So my question was, should I overhaul the present engine or look for one with good logs? TCM has informed the FAA that it intends to maintain a 24 to 48 hour turn-around time for notification of the crankshaft airworthiness. Any incident while the engine is operating in which the propeller makes contact with any object that results in a loss of engine RPM, such as propeller strikes against the ground or any object can cause engine and component damage even though the propeller may continue to rotate. (ii) If TCM notifies you that the crankshaft is serviceable, the propeller assembly may be reinstalled. 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. Studies have shown that a 100-amp alternator can impose a. How much more time before overhaul is remaining on the engine? 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. Just a few short months ago, Textron Lycoming's Service Letter L-163C recommended taking the engine apart for inspection following any incident involving propeller blade damage. Forums. Posted at 11:12h in don franklin oil change somerset ky by royal This repetition of headings to form internal navigation links 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. dont do it. 12866. The Lycoming information is more complicated and equivocating than the TCM directives in our opinion, as well explain. These tools are designed to help you understand the official document If it has, and there's no indication in the engine logs about a teardown and inspection, it's time for a long explanation from the seller. 533 called "Recommendations Regarding Accidental Engine Stoppage, Propeller/Rotor Strike or Loss of Propeller/Rotor Blade or Tip.". 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. I've heard that a Continental doesn't require a tear #1. Prop strike on Continental. Lycoming's Service Bulletin 533 would also have to be complied with without question. The President of the United States communicates information on holidays, commemorations, special observances, trade, and policy through Proclamations. Lycoming has reports of ground strikes, which have resulted in overstressed connecting rod bolts, that failed later. 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. These are the requirements as we see them. This could indicate a gear-up landing, or other source of damage that took time to fix. 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? Also, on prop strikes involving frontal impact, the crank can be pushed back into the engine, cracking the case at the slinger ring, and this may not be visible. 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. ", 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. If you can imagine a loose rod banging around inside your engine, you know it's bad. Lycoming is particularly concerned with this area and outlines specific inspection criteria with the force of AD 2004-10-14 to support their bulletin SB 475C depending on engine model. As for dialing the flange, he said TCM nitrides the crank so checking the run-out of the flange is a waste of time. continental prop strike ad continental prop strike ad. 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. 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 the TCM internet site www.tcmlink.com. This information may be examined at the FAA, New England Region, Office of the Regional Counsel, 12 New England Executive Park, Burlington, MA; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC. If the engine is being disassembled does the estimate include testing after reassembly? 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). A special note to experimental aircraft builders or someone looking for an engine upgrade: Beware of that great deal on an engine with a less than stellar or unknown history. Dialing in the flange is worthless for this. Yet, the company recently published a new Service Bulletin, SB No. PROPELLER STRIKE INSPECTIONS. While every effort has been made to ensure that 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. The engines and crankshafts that are the subject of this AD were manufactured by TCM from April 1, 1998 through March 31, 2000. headings within the legal text of Federal Register documents. But if there's 1,000 hours or more left on the engine, you're probably better off with just an inspection. 01/17/2023, 249 Then, put the pieces of the puzzle together for your customer and explain what needs to be done. That AD requires removing a core sample of material from the propeller mounting flange and sending the core sample to TCM for evaluation. The bulletin reads as follows: After defining a prop strike, TCM's SB 96-11A states: "A. Propeller strike inspections. Following any propeller strike complete disassembly and inspection of all rotating engine components is mandatory and must be accomplished prior to further operation. Inspect all engine accessories in accordance with the manufacturer's instructions." It also does not equivocate to any degree on an engine tear down being the mandatory procedure, which is described in the bulletin. provide legal notice to the public or judicial notice to the courts. Section 39.13 is amended by adding the following new airworthiness directive: 2000-23-21 Teledyne Continental Motors: Amendment 39-11994. by the Federal Energy Regulatory Commission In addition, propeller strikes also include situations where an aircraft is 01/17/2023, 823 These can be useful on FederalRegister.gov In some cases we really take issue with some directives being a bit excessive, but the prop strike directives we believe are a pretty reasonable course to follow, even if you have the option to not follow them if you are a Part 91 operator or are not affected by AD 2004-10-14, which well address below. It defines a sudden engine stoppage as; stopping an engine in one revolution or less for any reason, be it from propeller impact or from an engine failure of some sort. He also said prospective owners should review the logs to see if the propeller has been changed. documents in the last year, 946 The accident was recorded on video and available on the Internet. 2000-NE-16-AD, 12 New England Executive Park, Burlington, MA 01803-5299. You could identify its sound with your eyes closed. Basically anything that moves is subject to visual and other forms of nondestructive testing. documents in the last year. The President of the United States issues other types of documents, including but not limited to; memoranda, notices, determinations, letters, messages, and orders. We have personally seen an instance where a plane lost the entire prop in flight following a so called minor prior strike of hitting a runway light while taxing, but the crank on the IO-520 was only checked for run-out and prop repaired (and this was a Part 135 operated plane). This is one failure no one wants to experience. Start with all relative ADs, collect all service bulletins and service letters offered by the particular engine manufacturer, and sit with the insurance adjuster. Below are three important links from the FAA, Lycoming, and Teledyne Continental regarding the definition of a Prop Strike and sudden stoppage. All rights reserved. are not part of the published document itself. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). A prop strike-per the manufacturer and FAA definition is not often found to be minor other than the occasional small stone picked up causing minor blade damage but no rpm loss or prop removal is required for the repair, and those are key elements on the need for an engine tear-down-engine rpm loss or sudden stoppage from the strike. My investigation started with my need for another engine for my Cessna 210. The argument goes would you rather be paying for an in flight engine failure 100 hours from now. As mentioned earlier, Advisory Circular 43.13-1B, Chapter 8 defines a sudden engine stoppage as stopping an operating engine in one revolution or less for any reason, period, and includes prop-strike damage as a subset of the of sudden stoppage definition (at least the way we interpret the way it is written). Replace the rotobroach after the sixth core sample, or before if the rotobroach does not cut with the maximum torque applied. Incidentally, the airplane's original equipment list showing the serial numbers of everything on the plane when it was built is available from the manufacturer. include documents scheduled for later issues, at the request documents in the last year, 973 The Public Inspection page may also Textron Lycoming must take the position that in the case of a sudden stoppage, propeller/rotor strike or loss of propeller/ rotor blade or tip, the safest procedure is to remove and disassemble the engine and completely inspect the reciprocating and rotating parts including crankshaft gear and dowel parts. of the issuing agency. Comments for inclusion in the Rules Docket must be received on or before January 26, 2001. The documents posted on this site are XML renditions of published Federal "The result is that those flyweights that are hanging on by 1/8-inch pins can easily bend, twist, or damage those pins. For more than three decades, customers have trusted their airplanes to Triad Aviation, Inc. SUMMARY: The FAA is adopting a new airworthiness directive (AD) that supersedes an existing AD, for Lycoming Engines (formerly Textron Lycoming), direct-drive They are often ignored in the prop-strike evaluation, yet they have prescribed inspection criteria even if involved in only a sudden stoppage. 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. In fact it is a very insidious situation since there is often no obvious damage-no harm, no foul so to speak. 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. My group also argued about the propeller hitting grass and water. documents in the last year, 84 SENSENICH WOOD PROPELLER COMPANY LOCATED IN PLANT CITY, FL. Although many in the industry still like to interpret rules to their advantage, the mechanic is being faced with fewer and fewer "outs" The pressure from an owner to ignore the engine and fix the prop may be great, but it is certainly in the best interest of the mechanic's career to persuade the owner that any amount of damage to the propeller constitutes the need for a thorough inspection. We see flyweights and connecting hardware, in some designs, brutalized quite frequently by sudden stoppage. The prop had a good-size dent in it, prompting the pilot to remove the prop and send it in for repair. More than the prop and crankshaft Compliance with this service bulletin is mandatory per AD 91-14-22. 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. from 54 agencies. ", Airworthiness Directive 2004-10-14 is applicable to Lycoming engines that experienced a prop strike. (2) After obtaining the results of the core sample evaluation, disposition the crankshaft as follows: (i) If TCM notifies you that the crankshaft is not serviceable, replace the crankshaft with a serviceable crankshaft of the same part number before further flight. Textron Lycoming must take the position that in the case of a sudden engine stoppage, propeller/rotor strike or loss of propeller/rotor blade or tip, the safest procedure is to remove and disassemble the engine and completely inspect the reciprocating and rotating parts including crankshaft gear and dowel parts. the official SGML-based PDF version on govinfo.gov, those relying on it for In many instances prop strikes will fall into the major repair category, which necessitates repair station or manufacturer repair of the prop (if needed). 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 AD, defines a propeller strike as follows: (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 blade dressing. One, "A sudden rpm drop while impacting water, tall grass, or similar yielding medium, where propeller damage is not normally incurred." on 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. 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. Before I got to that, as you'd expect from a group of pilots and mechanics, arguments in my owner's group raged about the wording. 106(g), 40113, 44701. +1.251.436.8122 08:00 - 17:00 Gasoline Engines Parts +1.972.586.1000 24 hours Avionics +1.251.990.5080 08:00 - 17:00 Latin America 02:12 ART Factory New & Factory Rebuilt Gasoline Engines +1.251.436.8101 10:00 - 19:00 Gasoline Engine Overhauls & MRO +55.11.99923.9579 08:00 - 17:00 Technical Support (AvGas & Jet-A) +1.888.826.5465 09:00 - the most are "prop strike." Conditions 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. the Federal Register. documents in the last year, 830 The Public Inspection page But let me start this section with a caveat: There is no black and white, and the subject under discussion is the grayest of the gray areas. 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." Both Lycoming and Continental express concerns about prop-strikes causing damage to the rear of the crank in the vicinity of the rear radius of the oil slinger, which can be shoved back into the case rear. documents in the last year, 41 The thought of the damage and cost involved makes all of us shudder. How much liability insurance do you have? If possible, he suggests, mark the flange somehow, or take a photo of the scratches and nicks so you can compare it to the "new" one later. The actions specified by this AD are intended to prevent fracture of the crankshaft connecting rod journal, which could result in total engine power loss, in-flight engine failure and possible forced landing. What you see in the pictures is what you are getting. You can bet the fellow who hit the traffic cone never made a logbook entry unless the engine had to be repaired. 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. Everyone was happy and the prices were right. Not every prop strike results in sudden stoppage, but it doesn't take much to damage some of these accessories. 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. Removing and reinstalling a propeller take just a few hours, and the prop shops don't care who brings the job through the door. 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 engine for sale was the model I needed, with about 1,000 hours since a factory overhaul. The investigation revealed that the crankshafts failed due to subsurface defects in the number one crankshaft connecting rod journal. Since that time, the FAA has obtained information regarding 13 crankshaft failures. 01/17/2023, 284 Moreover, the crank is not the only critical element in a prop-strike incident. On Lycoming engines, which are not nitrided, the flange can be bent. On numerous occasions, Textron Lycoming has been consulted about recommendations on whether to continue using an aircraft engine that has been involved Many insurance companies will not pay for any inspection requirements unless damage from the incident is found during that inspection. This amendment supersedes emergency airworthiness directive (AD) 2000-08-51. documents in the last year, 876 FIND A DEALER. 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. and services, go to Kiss the old days goodbye. A Textron Lycoming engine, that is being operated on a Part 91 aircraft, that had a sudden engine stoppage, not a propeller strike, must comply with AD 91-14-22 and Service Bulletin 475B at a minimum. 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 I, 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. Use the PDF linked in the document sidebar for the official electronic format. 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 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. 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. Issued in Burlington, Massachusetts, on November 13, 2000. 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. 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. 01/17/2023, 202 Lycoming also has a short, two-page separate, specific prop-strike bulletin, SB533A, which is dated in 1999, five years earlier than AD 2004-10-14, and four years earlier than SB 475C. documents in the last year, 480 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. Compliance with this service bulletin is mandatory per AD 91-14-22. The AD specifies the inspection at each engine overhaul, after a propeller strike, sudden stoppage, or whenever gear train repair is required. Lycoming's new SB seems to generalize the term propeller strike and sudden stoppage to be quite inclusive. It is not an official legal edition of the Federal Or it could be an engine with illegal performance enhancements for a certified engine such as shaved decks to increase compression. documents in the last year, 1401 This can cause major internal engine damage without visible prop damage. CONTINENTAL TSIO-520-J $18,995 FOR SALE Engine with Accessories TSMO=488.2 No Prop Strike Photos, logs, details per request. Information about this document as published in the Federal Register. The FAA definition of a sudden stoppage, is the engine stopping suddenly in under one rpm. Refer McCauley Service Bulletin 137W. 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. At least thats our goal. So carefully consider all factors related to propeller strikes. Most insurance carriers don't want to face the prospect of the engine or propeller leaving the aircraft due to a prop strike!". (j) 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. Accordingly, the FAA has not consulted with state authorities prior to publication of this proposed rule. on 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." MSB 005C lists additional serial numbers (SN's) of affected engines and suspect crankshafts that were manufactured between April 1, 1998, and March 31, 2000, inclusive. 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. has no substantive legal effect. You will note TCM does not get into the concept of sudden stoppages possibly being handled differently as Lycoming does. These markup elements allow the user to see how the document follows the 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. what would martial law in russia mean phoebe arnstein wedding joey michelle knight son picture brown surname jamaica. documents in the last year, by the Veterans Affairs Department as a result of sudden stoppage. That engine may be a time bomb, and an illegal one if the data plate is still on the engine, as after some mods it no longer qualifies as a certified engine, and may not be economically able to be recertified, depending on what was done to it. My investigation started with my need for another engine for my Cessna 210. 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. To be undiplomatic, dialing in a crank after a prop strike or sudden stoppage as has been defined by both the manufacturers and the FAA is essentially a fools errand-at least as possible decision making criteria on the serviceability of the crank. documents in the last year, 1487 documents in the last year, 534 You will also find additional info detailing prop damage repair, minor to major, irrespective of any of the prop strike consideration. A prop-strike also imposes terrific jamming forces backward on the rear of the case-where the gearing is located and easily damaged. establishing the XML-based Federal Register as an ACFR-sanctioned for better understanding how a document is structured but "You naturally think of the crankshaft and things that are directly connected to the engine, but you don't think of other accessories. 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.
