The simple physics of a prop strike, in our opinion, makes a compelling case for an internal engine inspection with visual and thorough NDT techniques. Well, for one i dont think i want to take out any of the clubs planes ever again. A Rule by the Federal Aviation Administration on 11/27/2000. Schwaner made the point that more than a few people have been told their engine's crank is bad, but it just so happens that the shop has the one you need in stock. Any decision to operate an engine which was involved in a sudden stoppage, propeller/rotor strike or loss of propeller/rotor blade or tip without such an inspection must be the responsibility of the agency returning the aircraft to service. He continues, "T.C.M. Inspect all engine accessories in accordance with the manufacturer's instructions.". Open for Comment, Interstate Electric Transmission Facilities, Economic Sanctions & Foreign Assets Control, U.S. As he approached the director of maintenance he asks, Pilot: "When does a prop strike require engine tear-down and inspection? Both Lycoming and Continental have very specific requirements for disassembly and inspection. 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. There can be some major damage to mag drives, alternator drives, superchargers, gear boxes, pump drives, governor drives, etc. 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. include documents scheduled for later issues, at the request in the separation of the propeller/rotor blade from the hub, the loss of a propeller/rotor blade tip or sudden stoppage following accidental propeller/rotor damage (such as propeller/rotor strike). There used to be, but it was kind of informal and there was a lot open to interpretation. on 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. to a sudden stop. 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. TCM mandatory service bulletin (MSB) 005B, dated May 25, 2000, and MSB 005C, dated October 10, 2000, were issued to include the SN's of those additional suspect crankshafts. Its not a smoking gun, but perusing the accident reports makes one wonder about such coincidences. McCauley hubs must be retired if any of the blades within the assembly are bent beyond repair limits inboard of the 85 percent blade radius. Information about this document as published in the Federal Register. There may be other additional requirements mandated by insurance policies or engine manufacturer and/or overhauler warranty. Without even trying, the FAA did what hasn't been done since 9/11: It cleared the airspace of commercial traffic. 2023 Endeavor Business Media, LLC. 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. Forums. Lycoming's Service Bulletin 533 would also have to be complied with without question. rendition of the daily Federal Register on FederalRegister.gov does not Per the Lycoming website it is still an active bulletin, which we quote in part as follows: (It has all the same definitions found in AD 2004-10-14 that we printed in italics but has additional information): FAA Partners With Korea On Advanced Air Mobility, Guest Blog: Why Aircraft Engines Should Be Hard To Start, Southwest: The Ghost Of Jack Welch Part II, And Now, A ChatBot For All Your Aviation Questions, Best Of The Web: How The Rolls-Royce Merlin Became A World, Best Of The Web: Why Wingsuits Are Flight As Pure As, General Aviation Accident Bulletin, January 16, 2023, Top Letters And Comments, January 13, 2023, National Museum Of The U.S. Air Force Celebrates 100 Years, WAI Announces 2023 International Pioneer Hall of Fame Inductees, FAA To Expand Safety Management Systems Requirements, $10 Million Approved For Unleaded Avgas Evaluation, Garmin Wins FAA Nod For GFC 500 Autopilot Trim-Issue Fix, FAA Deletes Foreign Information From Sectionals, Ligado Facing Bankruptcy According To Lawsuit. documents in the last year, by the Fish and Wildlife Service Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Code of Federal Regulations (14 CFR part 39) as follows: 1.

A propeller strike can occur at taxi speeds and during touch-and-go operations with propeller tip ground contact. There's also the cost of inspection of the accessories, which is extra. (b) After the effective date of this AD, do not install a crankshaft with a SN that is Start Printed Page 70656listed in MSB 00-5C, dated October 10, 2000, unless core samples have been taken and TCM has approved it for return to service. On numerous occasions, Textron Lycoming has been consulted about recommendations on whether to continue using an aircraft engine that has been involved 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. New posts Search forums. of the issuing agency. Sep 28, 2016. The engine makers seem to agree quite strongly as does the FAA. What looks like light damage may sometimes result in something broken or highly stressed inside, while a major collision shows nothing wrong after it's been torn down." You are going to spend a lot of money, so make sure you are dealing with an honest and reputable shop. On November 24, 1999, the FAA was notified of a crankshaft failure on a TCM engine. 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 or she feels that it is the prudent and responsible thing to do. Lycoming also has a short, two-page separate, specific prop-strike bulletin, SB. Putting the puzzle together Never allow an insurance adjuster to dictate the inspection requirements after an incident. 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. The thought of the damage and cost involved makes all of us shudder. 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. informational resource until the Administrative Committee of the Federal How about 50 rpm? 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. Thread starterkevmor99. Although not a guarantee of any kind, the lack of movement showed that utter destruction had not occurred. continental prop strike ad. So carefully consider all factors related to propeller strikes. These cases should be handled as sudden stoppages because of potentially severe side loading on the crankshaft flange, front bearing, and seal.

The documents posted on this site are XML renditions of published Federal 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. Any decision to operate an engine, which was involved in a sudden stoppage, propeller/rotor strike or loss of propeller/rotor blade or tip without such an inspection must be the responsibility of the agency returning the aircraft to service. 12866. A. The President of the United States manages the operations of the Executive branch of Government through Executive orders. Start dateSep 28, 2016. In this case however, there is an existing AD for quite a few differentLycoming 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. Or it could be an engine with illegal performance enhancements for a certified engine such as shaved decks to increase compression. Each document posted on the site includes a link to the Unfortunately, it may be the next owner who discovers any hidden damage. documents in the last year, 946 This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Atlanta Aircraft Certification Office (ACO). The pins are more than adequate for running loads, but they are totally inadequate when you subject them to sudden stoppage. Actually they are fairly consistent. Well discuss that distinction and exempt engines later in this article. DeJoris says he is dealing with claims adjusters on a regular basis, and many adjusters today choose to have you go the extra mile and tear down the entire engine and propeller and do a thorough inspection." 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. This amendment requires removing a core sample of material from the propeller mounting flange of certain crankshafts, and sending the core sample to TCM for evaluation. 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. 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. Aircraft Owners & Pilots Association Find it free on the store. Phone: (813) 752-3711 SUMMARY: The FAA is adopting a new airworthiness directive (AD) that supersedes an existing AD, for Lycoming Engines (formerly Textron Lycoming), direct-drive A prop-strike also imposes terrific jamming forces backward on the rear of the case-where the gearing is located and easily damaged. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); WORLD'S PREMIER INDEPENDENT AVIATION NEWS RESOURCE. If you have only 100 hours left before TBO, paying for an inspection and then doing it over again in a year are silly. Some elbow room? The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and is not a significant regulatory action under Executive Order No. PROPELLER STRIKE INSPECTIONS. (1) Do the crankshaft material inspection (crankshaft propeller flange core sample) in accordance with sections A through J of TCM MSB 00-5C, dated October 10, 2000, as follows: (i) Use the specialized tools and equipment provided by TCM as listed in section A of TCM MSB 00-5C, dated October 10, 2000. electronic version on GPOs govinfo.gov. But what is a prop strike and what exactly are the ramifications? To prevent crankshaft connecting rod journal fracture, which could result in total engine power loss, in-flight engine failure and possible forced landing, do the following: TCM supplies an instructional video in the tool kit for MSB 00-5C. In fact, the customers were sold their own crank. To start my investigation, I wanted the official definition of a prop strike. That said, you'll understand that this article isn't going to state, or even hint at, what you should do in this situation. The other thing to consider is all of the accessories on the engine or parts of the engine that are spinning at high speeds that could come 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. This proposed rule does not have federalism implications, as defined in Executive Order No. On the record, owners said that if someone came into their shop and said he or she had an aircraft with a prop strike, they would follow the procedures outlined above to the letter.

If you can imagine a loose rod banging around inside your engine, you know it's bad. Dealing with them on this issue is fodder for another article, however. Pre-Flight. PROPELLER STRIKE INSPECTIONS. Per the Lycoming website it is still an active bulletin, which we quote in part as follows: On numerous occasions Textron Lycoming has been consulted about recommendations on whether to continue using an aircraft engine that has been involved in the separation of the propeller/rotor blade from the hub, the loss of a propeller/rotor blade tip or sudden stoppage following accidental propeller/rotor damage (such as propeller/rotor strike). Prior to any ground operation of the engine assure that the propeller flange and the crankshaft flange area are free of any crack indications in addition to the engine component inspection. 1 in 2022, Southwest To Build Aircraft Hangar, Create 100 Jobs at Reid Airport, Boeing, United Airlines Finalize 737 MAX and 787 Order, Including Record Purchase for 100 Dreamliners. Moreover, 43.13-1B mandates the use of approved manufacturer data (providing it exists) rather than 43.13-1B data as the required source of both inspection and repair information (Manufacturer data will be more current with more detail and part specific is the thinking). 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. 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." 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. The engine for sale was the model I needed, with about 1,000 hours since a factory overhaul. A full overhaul will cost about $12,500 plus accessories. I alluded to the potential of buying an airplane that suffered a prop strike without the required inspections being completed. Kiss the old days goodbye. Refer McCauley Service Bulletin 137W. Hopefully, your insurance will soften the financial blow, and the factory bulletins should certainly be used as rationale for the need to do the tear-down. How much liability insurance do you have?

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. documents in the last year, 973 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. Docket 2000-NE-16-AD. documents in the last year, 534 They all agreed that if it were their aircraft, they would think long and hard about doing a teardown and inspection. The investigation revealed that the crankshafts failed due to subsurface defects in the number one crankshaft connecting rod journal. Should he also have performed the obligatory engine inspections? For engines that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (d) of this AD. Propeller strike inspections. Engine inspection requirements after prop strikes can become complicated, however, and the regulations and recommendations seem to overlap and intertwine. Lycoming has reports of ground strikes, which have resulted in overstressed connecting rod bolts, that failed later. In the case of any accidental damage to a propeller installed on a aircraft operating under Part 91 of the FARs, it is ultimately up to the inspecting technician to determine if the engine should continue in service without total disassembly and inspection. Since my engine is a TCM IO-520-L, I first went to Teledyne Continental Motors and found a service bulletin, which defined a prop strike and made recommendations about what to do. Its also important to point out that this is not the only Lycoming bulletinthat discusses prop strikes. Although many in the industry still like to interpret rules to their advantage, the mechanic is being faced with fewer and fewer "outs" and services, go to After defining a prop strike, TCM's SB 96-11A states: "A. So, when it comes time for that prop strike/sudden.
