Either may require additional inspection but neither may negate the inspections required by the FARs. Maybe it is and maybe it isn't." I spoke with several shop owners and asked their opinion. Section 39.13 is amended by adding the following new airworthiness directive: 2000-23-21 Teledyne Continental Motors: Amendment 39-11994. They are often ignored in the prop-strike evaluation, yet they have prescribed inspection criteria even if involved in only a sudden stoppage. 12866. Yet, the company recently published a new Service Bulletin, SB No. At Unlimited Aero Engines we know that things happen, and happen fast. documents in the last year, 84 Ken Tunnel of Lycon Aircraft Engines in Visalia, California, an engine facility used by a number of owners of show airplanes, said, "There's no way you can tell if there's any damage regardless of the circumstances. (3) A sudden RPM drop while impacting water, tall grass, or similar yielding medium, where propeller damage is not normally incurred. Propeller strike inspections. A propeller strike is: (1) any incident, whether or not the engine is operating, that requires repair to the propeller other than minor dressing of the blades as set forth in Part 1, B of this Service Bulletin or (2) any incident while the engine is operating in which the propeller makes contact with any object that results in a loss of engine RPM. Register, and does not replace the official print version or the official Posted at 11:12h in don franklin oil change somerset ky by royal PROP STRIKE. (ii) If TCM notifies you that the crankshaft is serviceable, the propeller assembly may be reinstalled. Russell says, it should be noted that to comply with A.D. note 91-14-22, the engine does not need to be completely disassembled and that access to the accessory gear train can be accomplished, in most cases, with the engine still installed in the aircraft. #1. Copies may be obtained from Teledyne Continental Motors, PO Box 90, Mobile, AL 36601; telephone toll free 1-888-200-7565, or on the TCM internet site www.tcmlink.com. There are other things that have to be checked, including the magnetos, propeller governor, and fuel system. Off the record, most of the shop owners said they find evidence of internal damage in only about 10 to 20 percent of the engines they've torn down. Comments may also be sent via the Internet using the following address: 9-ane-adcomment@faa.gov. Comments sent via the Internet must contain the docket number in the subject line. No more filing blades a bit shorter after a tip strike, or performing a run-up and signing off on an engine after the runway lights have been mowed a bit shorter. Everyone was happy and the prices were right. If the engine is being disassembled does the estimate include testing after reassembly? Factory New & Factory Rebuilt Gasoline Engines +1.251.436.8101 08:00 - 17:00 Gasoline Engine Overhauls & MRO +1.251.990.5080 08:00 - 17:00 Technical Support (AvGas & According to DeJoris, "Hartzell requires hub replacement if any blade in the assembly is bent beyond repair limits due to impact damage. According to the salvage yard, the prop strike came about after an out-of-fuel landing on a road in Louisiana. More than the prop and crankshaft documents in the last year, 37 If the engine was assembled new, rebuilt, or overhauled on or before March 31, 1998, or on or after April 1, 2000, no action is required. And as we previously mentioned, the Lycoming 475C bulletin is broader than a prop strike; it is oriented to general engine overhaul crank inspections or crankshaft gear removal for inspection as well as prop strikes. The rationale for this hub retirement criteria revolves around the fact that forces great enough to bend blades beyond their respective repair limits represent loads that are in excess of those that the hubs were designed to withstand, while providing sufficient structural safety margins.". Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed. He used a football analogy of a player who can be brutally tackled and get right up, then trip over a bucket and break his leg. What you see in the pictures is what you are getting. Some geared alternators shafts use gears that are designed to slip on overloads, but older versions of this alternator gear do not have this design, and the gear shear design is for an alternator failure not a crank stoppage. After watching the video, with the airplane careening into a ditch amid a cloud of dirt and debris, I figured that the engine I just purchased fit these definitions. We will not be discussing damage to the prop in this article since there is so much information on prop damage that does not involve engine tear downs. Re: O-360 propeller indexing (noticeable slight vibration) Lycoming O-360 A-1As (and every other O-360 Ive met) propellers should be indexed such that the propeller stops at the 10 and 4 o'clock position (viewed from the front facing aft) when the engine shuts down. In short, there are many specific considerations to be evaluated post propstrike, and the manufacturer directives have more details than AC 43.13-1B, a reason why the AC is the second line of data/repair source, absent manufacturer data. The deffination of a prop strike is different on Lycomings than Continentals, Lycoming says any time a prop strikes any thing that will cause a loss of RPM it is a prop strike. TCM SB 96-11B defines a propeller strike as follows, and we paraphrase: First, any incident, whether or not the engine is operating, that requires repair to the propeller other than minor dressing of the blades, for instance where the propeller is damaged by a small foreign object during operation, such as a small stone. TCM-powered aircraft operating under Part 135 of the FARs that have to comply with all manufacturers service bulletins would have to comply with Service Bulletin 96-11B, dealing with prop strikes, dated July 2008, requiring total disassembly and inspection after any incident that requires removal of the propeller for repairs or if the engine physically lost any rpms during the incident. (iv) Do not exceed the torque limits specified in TCM MSB 00-5C, dated October 10, 2000, when obtaining the core sample. Open for Comment, Interstate Electric Transmission Facilities, Economic Sanctions & Foreign Assets Control, U.S. After defining a prop strike, TCM's SB 96-11A states: "A. So, in a roundabout way by the last paragraph, Lycoming is saying its the repair facilitys call unless your engine is one found in the later AD 2004-10-14, which applies to a lot of Lycoming engines. Another problem area is in engines with crank counterweights, a very common design. 01/17/2023, 249 Kennedy Airport Jetliner Aborts Takeoff To Avoid Another Jet Crossing Runway, FAA Says; Agency Investigating, FAA Releases Audio From Deadly Wings Over Dallas Air Show Crash Between Air Boss, Pilots, Year-End Surge Boosts Boeing, but Airbus Still No. Highly stressed connecting rod bolts also take a beating from a prop-strike, which can cause a slight stretch. 01/17/2023, 159 However the dates that the engines and crankshafts were delivered may not coincide with their dates of manufacture. documents in the last year, 946 While every effort has been made to ensure that Comments for inclusion in the Rules Docket must be received on or before January 26, 2001. documents in the last year, 876 It turned out to be a salvage shop and the owner confirmed that the logs for the engine were available, and the crank had been dialed, and found to be OK. Dialing checks the run-out, which is the amount of movement at the flange when the crank is rotated. This repetition of headings to form internal navigation links Even with a small engine that is generating say, 150 horsepower; if that power just suddenly stops, the torque from the engine has to be dissipated somewhere. During the subsequent takeoff, the airplane's right wing hit the mirror of a semitruck, which veered the airplane into a fire truck and eventually a ditch. Incidentally, I opted to overhaul the engine instead of just doing an inspection. One of the issues that is particularly hard to quantify if you elect not to tear an engine down, post strike and choose to disregard the fairly specific diagnostic procedures that the engine makers put out is do you have the FAA legal option of ignoring the service directives? That action was prompted by reports of crankshafts on which the connecting rod journals had fractured. the material on FederalRegister.gov is accurately displayed, consistent with ", In addition to regulatory changes and manufacturer recommendations, insurance companies are also playing a major role in determining what you do to your engine and prop. All comments submitted will be available, both before and after the closing date for comments, in the Rules Docket for examination by interested persons. documents in the last year, 480 In our response to readers we quote the latest manufacturer directives and FAA guidance, and add our perspectives and experience to hopefully help the owner feel his or her ultimate decision is the right and legal one. I won't list them all here, but some of the more expensive ones are: hydraulic valve lifters, connecting rod bearings, the crankshaft's main and thrust bearings, all needle, ball, and roller bearings, exhaust valves, valve springs, piston pins, pistons, crankcase through bolts, all the hardware, seals, gaskets, O-rings, and lots of other small stuff. 106(g), 40113, 44701. Our designation as a Cessna Service Center and authorization as a parts and engine distributor for both Lycoming and Continental But if there's 1,000 hours or more left on the engine, you're probably better off with just an inspection. Anderson, owner of Corona Cylinder and Engine Overhaul, said the cost of a teardown and inspection, for a small four-cylinder engine like the O-360 or -320, is about $4,000. TCM's SB 97-6 specifies the mandatory items that must be replaced when the engine is torn down. FAA# JL4R288M | EASA.145.4115 | Toll Free: 800-282-3202 | 954-970-3200 One, "A sudden rpm drop while impacting water, tall grass, or similar yielding medium, where propeller damage is not normally incurred." I bought the engine and started my quest to determine what I absolutely had to do to get the airplane airworthy. The FAA has determined that all of the defects were due to unique material composition characteristics combined with process control variations that occurred during the material melt process. There's a tremendous amount of energy stored in the rotating flyweight, and when all of a sudden you stop the prop and engine, that energy has to be dissipated somewhere.". has no substantive legal effect. informational resource until the Administrative Committee of the Federal The authority citation for part 39 continues to read as follows: Authority: documents in the last year, 28 Talking about whether to have the engine overhauled or just inspected, Tunnel said it can be penciled out. Recently, a transient aircraft hit a rubber traffic cone with the prop and kept going, taking off and disappearing into the western sky. ", Case in point The answer is yes, you can ignore the directive to the same degree that any one who operates under Part 91 does with any other service directive without the force of an AD behind it. Aircraft was involved in a prop strike. to a sudden stop. Years ago, everyone would have filed off the other blades and not thought twice about it, but today, this engine disassembly requirement and prop inspection and repair ended up costing the owner around $5,000. Moreover, the crank is not the only critical element in a prop-strike incident. The thought of the damage and cost involved makes all of us shudder. documents in the last year, 41 Definition of Propeller Strike (i) For the purposes of this AD, a propeller strike is defined as follows: (1) Any incident, whether or not the engine is operating, that requires repair to the propeller other than minor dressing of the blades. on NARA's archives.gov. This is not restricted to propeller strikes againstthe ground. And two, "The preceding definitions include situations where an aircraft is stationary and the landing gear collapses causing one or more blades to be substantially bent, or where a hangar door (or other object) strikes the propeller blade. Finding out what needs to be done and whether that agrees with what you feel should be done, whos going to do it and who is going to pay for it, should help make the experience of a prop strike/sudden stoppage as painless as possible. (2) Any incident during engine operation in which the propeller impacts a solid object that causes a And anyway, who needs NOTAMs? Also, some engines with a gear-driven alternator have a large, relatively thin and very vulnerable gear bolted to the forward end of the crankshaft. The thought of the damage and cost involved makes all of us shudder. I alluded to the potential of buying an airplane that suffered a prop strike without the required inspections being completed. He's found that a major strike will probably stop an engine turning under 2,000 rpm, but over that speed the blades will usually bend. The engine for sale was the model I needed, with about 1,000 hours since a factory overhaul. You can find the Service Bulletins for Continental Aerospace Technologies Type Certificated Gasoline Engines below. Still others will only pay for the labor to do the job and will not pay for any parts. Inspect all engine driven accessories in accordance with the manufacturers maintenance instructions. Consider the accessories. A bit of homework will go a long way towards helping you persuade your customer to do the right thing. include documents scheduled for later issues, at the request Its possible to do major engine/accessory damage without obviously damaging the prop by hitting water or heavy, tall grass that stops or slows the running engine. Phone: (813) 752-3711 TCM has informed the FAA that it intends to maintain a 24 to 48 hour turn-around time for notification of the crankshaft airworthiness. A propeller strike can occur at taxi speeds and during touch-and-go operations with propeller tip ground contact. documents in the last year, 16 O-435, and TIO-541 series engines being exempt. Airmark Overhaul, Inc. 6001 NW 29th Avenue Fort Lauderdale, FL 33309. This article originally appeared in the December 2012 issue of Light Plane Maintenance. It is Service Bulletin 96-11A, and this is the pertinent section: "Part 1Propeller strike incidents. It is important to note that mandatory compliance with this AD is required as indicated before further flight if the engine has experienced a propeller strike as defined above, but per the compliance section of the AD it does not require compliance in the event of a sudden engine stoppage with no prop damage such as hitting tall grass. Unfortunately, it had experienced a prop strike. Compliance with the requirements of this AD is required within the next 10 hours time-in-service from the effective date of this AD, unless already done. Start dateSep 28, 2016. certain lots, of steel production or forming operations. SENSENICH WOOD PROPELLER COMPANY LOCATED IN PLANT CITY, FL. Register documents. This year's numbers have placed us in the top 10, highlighting another strong year of property development. CONTINENTAL TSIO-520-J $18,995 FOR SALE Engine with Accessories TSMO=488.2 No Prop Strike Photos, logs, details per request. To start my investigation, I wanted the official definition of a prop strike. A prop that hits so hard as to bend the crank flange is only one of several considerations. A propeller strike (according to this Lycoming bulletin) is defined as follows:(It has all the same definitions found in AD 2004-10-14 that we printed in italics but has additional information): Circumstances which surround accidents are many and varied; therefore, the circumstances of the accident can not, in our opinion, be used to predict the extent of the damage to the engine or assure its future reliability. On TCM engines with the geared alternators up front, he has seen the mounting flange and the gear drive bolts break during a prop strike. Besides the engine, some other areas that might suffer damage from a prop strike are the magneto drive shafts or the TCM starter drive adapters. More information and documentation can be found in our Federal Register. When a prop strike incident occured, standard industry accesptance was to have the mechanic remove the propeller and dial indicator, "or check the crankshaft flange for being out of limits." publication in the future. All crankshafts that are found to be unserviceable must be replaced with a serviceable crankshaft prior to further flight. All of the fractures have been grouped around certain manufacturing dates between April 1, 1998, and March 31, 2000, inclusive. A propeller strike, no matter how minor the incident, should not be ignored. Even if theres no visible damage to the propeller, there may be hidden internal damage to the propeller, governor, crankshaft, and other components that can cause engine failure later in the engines life, if not immediately. (f) This amendment becomes effective on December 12, 2000. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Atlanta ACO. These markup elements allow the user to see how the document follows the The Lycoming information is more complicated and equivocating than the TCM directives in our opinion, as well explain. I've heard that a Continental doesn't require a tear He also said that if you have a prop strike while traveling, don't go to the first shop you see and turn the airplane over to it. A tear down of most direct drive engines isnt a major repair but we recommend using a certified repair station or the factory for that action as well as the level of NDT testing will be significant and required to be done by certified people for such critical NDT inspections. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket. (c) Crankshaft material inspections (crankshaft propeller flange core samples) that were done using TCM MSB 00-5, dated April 14, 2000; MSB 00-5A, dated April 28, 2000; or MSB 00-5B, dated May 25, 2000, comply with this AD and must not be repeated. The FAA has reviewed and approved the technical contents of TCM Mandatory Service Bulletin (MSB) 005C, dated October 10, 2000. ", Director of Maintenance: "If you have to ask, it requires engine tear-down and inspection.". Basically anything that moves is subject to visual and other forms of nondestructive testing. The President of the United States manages the operations of the Executive branch of Government through Executive orders. Definition of Propeller Strike (i) For the purposes of this AD, a propeller strike is defined as follows: (1) Any incident, whether or not the engine is operating, that requires repair to the propeller other than minor dressing of the blades. "The result is that those flyweights that are hanging on by 1/8-inch pins can easily bend, twist, or damage those pins. Both major engine manufacturer's have service literature that explains the desired course of action after accidental propeller damage and, in the case of Teledyne Continental, defines what their interpretation of a propeller strike is.". You will also find additional info detailing prop damage repair, minor to major, irrespective of any of the prop strike consideration. Prop strike on Continental. He continues, "T.C.M. How much more time before overhaul is remaining on the engine? Its also important to point out that this is not the only Lycoming bulletinthat discusses prop strikes. Actually they are fairly consistent. Now that I had a definition, what would I have to do about such an event? Always rely on the FAA certified inspecting technician, applicable service data and the FARs to dictate how thorough an inspection is necessary to continue the engine in service. Continental Motors states: A propeller strike is: (1) any incident, whether or not the engine is operating, that requires repair to the propeller other than minor dressing of the blades as set Got a nick on your prop? Should he also have performed the obligatory engine inspections? It is recommended that the technician views and understands Instructional Video for Compliance with Teledyne Continental Motors Mandatory Service Bulletin MSB 00-5C before performing these procedures. As he approached the director of maintenance he asks, Pilot: "When does a prop strike require engine tear-down and inspection? I took the other SR20 this time and it was also broken, to the point where it shouldn't have been flown. According to John DeJoris, president of Aircraft Propeller Service Inc., in Wheeling, IL, "The FAA has embraced the policy that any type of propeller strike is a cause for teardown and engine manufacturers are quickly jumping on board. Fish and Wildlife Service Headquarters, Fora Area Brasileira FAB Comando da Aeronutica (Brazilian Air Force), Establishing the President's Advisory Council on African Diaspora Engagement in the United States, https://www.federalregister.gov/d/00-29496, MODS: Government Publishing Office metadata. Second, any time foreign object damage requires propeller removal for repairs other than the minor dressing of the blades as mentioned above, the incident is considered a propeller strike and must be inspected as outlined in SB 96-11B. "It" 2023 Aviation Publishing Group. Thread starterkevmor99. My investigation started with my need for another engine for my Cessna 210. However, they have the caveat that the inspecting mechanic may override that position and return the engine to service without disassembly and inspection if he feels that it is the prudent and responsible thing to do. documents in the last year, 830 The following was overheard recently at a maintenance facility after a very irritable looking pilot walked in with a look of embarrassment on his face. That said, you'll understand that this article isn't going to state, or even hint at, what you should do in this situation. TCM is less equivocal. Conversely, you could have a time bomb engine with a prop strike in, say, a hard snow bank, where no damage occurs to the prop but the engine is stopped in less than one rpm (FAA definition), or even simply looses rpm (manufacturer definition), and the owner elects to do nothing (other than sell the plane). On April 28, 2000, the Federal Aviation Administration (FAA) issued emergency airworthiness directive (AD) 2000-08-51 that is applicable to Teledyne Continental Motors IO-360, TSIO-360, LTSIO-360, O-470, IO-470, TSIO-470, IO-520, TSIO-520, LTSIO-520, IO-550, TSIO-550, and TSIOL-550 series reciprocating engines. Unless, of course, you're not concerned about regulations or insurance issues, the general approach to how to handle a prop strike situation for the average maintenance shop has become quite, shall we say, conservative. Following any propeller strike, complete disassembly and inspection of all rotating engine components is mandatory and must be accomplished prior to further flight. The OFR/GPO partnership is committed to presenting accurate and reliable Even tip damage is considered cause for teardown So my question was, should I overhaul the present engine or look for one with good logs? Lycoming engines that specifically mentions prop strikes and mandates some degree of tear down, but not necessarily a full tear down, and only if it is a prop strike as opposed to a sudden stoppage. As for dialing the flange, he said TCM nitrides the crank so checking the run-out of the flange is a waste of time. Replace the rotobroach after the sixth core sample, or before if the rotobroach does not cut with the maximum torque applied. Bending loads alone are not the only destructive element, and nondestructive testing of the entire crank and associated structures is the only reasonable way to check it out. "You naturally think of the crankshaft and things that are directly connected to the engine, but you don't think of other accessories. In short, all accessories become suspect to damage under either a prop strike or sudden stoppage incident. There is also a measure of anecdotal evidence in the engine accident/incident statistics that engines that have a prop strike/sudden stoppage and owners who did not follow the manufacturer recommendations such as only checking the crankshaft run-out, have a higher incidence of broken cranks or other engine failures a number of flight hours later. Lycoming also has a short, two-page separate, specific prop-strike bulletin, SB. The service information referenced in this AD may be obtained from Teledyne Continental Motors, PO Box 90, Mobile, AL 36601; telephone toll free 1-888-200-7565, or on A.

This proposed rule does not have federalism implications, as defined in Executive Order No. what would martial law in russia mean phoebe arnstein wedding joey michelle knight son picture brown surname jamaica. AOPA Members DO more LEARN more SAVE more - Get MORE out of being a pilot -. and services, go to Over the years, Continental has built a service offering for aircraft operators and owners These services include engine overhauls at the Continental factory service center for Continental, Titan, and LYCOMING engines, factory overhauls for Continental AvGas engines, sudden stoppage/propeller strikes, shock inspections, fleet overhaul programs, Jet-A burning engine Do we think the engine makers are overly eager to have you tear down or dig into your engine? A slam stop will detune the weights and damage the bushings so they can no longer do their job of helping to balance the crank while operating. This may seem to contradict itself since sudden stoppage is mentioned earlier in the AD in the prop strike-definitions section, but thats the way it is written with an orientation to certain types of direct drive Lycoming engines, with only Lycoming O-145, O-320H, O-360E, LO-360E, LTO-360E,O-435, and TIO-541 series engines being exempt. documents in the last year, by the Transportation Security Administration The crankshaft SN is only used to determine the need for taking a core sample for those crankshafts identified in paragraph (a) and (b) of this AD. Sure, some of these arguments are specious, but the point is, there's a lot of gray area, and this can cause many incidents to be ignored. on FederalRegister.gov How much liability insurance do you have? Recent changes in the approach to propeller strikes dictated by Airworthiness Directives, engine manufacturer Service Letters, and insurance company policy have made anything less than a thorough teardown and NDT inspection unacceptable. Engines that have been rebuilt by TCM will have a letter R at the end of the six digit numerical portion. continental prop strike ad. This document has been published in the Federal Register. Jerry Robinette, Senior Engineer, Propulsion, Atlanta Aircraft Certification Office, FAA, Small Airplane Directorate, One Crown Center, 1895 Phoenix Blvd., Suite 450, Atlanta, GA 30349; telephone: (770) 703-6096, fax: (770) 703-6097. Be especially wary if this is some form of private cash sale that has to be done right away, unless you are planning to have it torn down and rebuilt by a shop with the right inspection equipment to inspect for crank and gear damage, and be prepared for costs potentially exceeding a factory reman engine i.e. Following any propeller strike complete disassembly and inspection of all rotating engine components is mandatory and must be accomplished prior to further operation. I took the ad to an engine overhaul shop, Corona Cylinder and Engine Overhaul in Corona, California, and had the owner, Joe Anderson, call the person selling the engine. The MSB also describes procedures for removing a core sample of material from the propeller mounting flange of the crankshaft and for cleaning, chamfering, dye checking, and painting the core sample holes. The engine SN can be found in logbooks or other maintenance records. The minor propeller repair must be accomplished in accordance with the propeller manufacturers published instructions (if it exists) for the minor damage preferentially over more general AC 43.13-1B with the exceptions we noted earlier). The oil pump on the Continental IO-360 is driven by a very small shaft, for instance, and can be easily sheared as a result of a strike," says DeJoris. continental prop strike ad 21 May. on If you have a favorite mechanic, he may know someone in the area who will pull the enginethis takes only a few hoursand ship it wherever you want. Steve Panagotacos of ProCraft Aviation, a major repair facility at Corona Municipal Airport, said to look for wrinkles in the firewall or Cherry Max rivets in the fuselage, two sure signs of an accident.
