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. on 49 U.S.C. To start my investigation, I wanted the official definition of a prop strike. 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. The President of the United States manages the operations of the Executive branch of Government through Executive orders. Register (ACFR) issues a regulation granting it official legal status. (2) Any incident during engine operation in which the propeller impacts a solid object that causes a Lycoming's Service Bulletin 533 would also have to be complied with without question. on Sep 28, 2016. to a sudden stop. 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. A prop-strike also imposes terrific jamming forces backward on the rear of the case-where the gearing is located and easily damaged. Section 39.13 is amended by adding the following new airworthiness directive: 2000-23-21 Teledyne Continental Motors: Amendment 39-11994. They all agreed that if it were their aircraft, they would think long and hard about doing a teardown and inspection. My investigation started with my need for another engine for my Cessna 210. Issued in Burlington, Massachusetts, on November 13, 2000. ", Case in point 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 A Rule by the Federal Aviation Administration on 11/27/2000. Everyone was happy and the prices were right. documents in the last year, 16 If you've attended AirVenture or any of the other major airshows, you've heard it. Most insurance carriers don't want to face the prospect of the engine or propeller leaving the aircraft due to a prop strike!". 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 Federal Register. Lycoming has reports of ground strikes, which have resulted in overstressed connecting rod bolts, that failed later. Document page views are updated periodically throughout the day and are cumulative counts for this document. 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. Putting the puzzle together These tools are designed to help you understand the official document This year's numbers have placed us in the top 10, highlighting another strong year of property development. Propeller strike inspections. 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 The engine makers seem to agree quite strongly as does the FAA. rendition of the daily Federal Register on FederalRegister.gov does not This proposed rule does not have federalism implications, as defined in Executive Order No. PROPELLER STRIKE INSPECTIONS. 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. TCM is less equivocal. 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. 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. Unfortunately, it may be the next owner who discovers any hidden damage. The Public Inspection page 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? 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. 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. One, "A sudden rpm drop while impacting water, tall grass, or similar yielding medium, where propeller damage is not normally incurred." I took the other SR20 this time and it was also broken, to the point where it shouldn't have been flown. These cases should be handled as sudden stoppages because of potentially severe side loading on the crankshaft flange, front bearing, and seal.". Some reports are quite specific about a recent prop strike in the engines history. 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. 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. I watched the video and figured the pilot had reduced power before hitting the ditch. Say the engine is turning only 1000 rpm, barely above an idle. the most are "prop strike." documents in the last year, 37 Never allow an insurance adjuster to dictate the inspection requirements after an incident. Aircraft Owners & Pilots Association Find it free on the store. 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. The documents posted on this site are XML renditions of published Federal He adds, "This limits their liability exposure. The thought of the damage and cost involved makes all of us shudder. PROP STRIKE. on Aircraft was involved in a prop strike. Prop strike. These two words are guaranteed to make any pilot wince. Should he also have performed the obligatory engine inspections? They are often ignored in the prop-strike evaluation, yet they have prescribed inspection criteria even if involved in only a sudden stoppage.

All communications received on or before the closing date for comments will be considered, and this rule may be amended in light of the comments received. "You naturally think of the crankshaft and things that are directly connected to the engine, but you don't think of other accessories. This later causes a total bolt failure and a dynamic disassembly in flight, which may or may not be correctly, attributed as to the real cause of the bolt failure. For more than three decades, customers have trusted their airplanes to Triad Aviation, Inc. Are any of the engines accessories inspected as they should be, and if so to what extent? In fact it is a very insidious situation since there is often no obvious damage-no harm, no foul so to speak. include documents scheduled for later issues, at the request That action was prompted by reports of crankshafts on which the connecting rod journals had fractured. Submit comments in triplicate to the Federal Aviation Administration (FAA), New England Region, Office of the Regional Counsel, Attention: Rules Docket No. Basically anything that moves is subject to visual and other forms of nondestructive testing. A bit of homework will go a long way towards helping you persuade your customer to do the right thing. A. Until the ACFR grants it official status, the XML On November 24, 1999, the FAA was notified of a crankshaft failure on a TCM engine. 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. As for dialing the flange, he said TCM nitrides the crank so checking the run-out of the flange is a waste of time. The investigation revealed that the crankshafts failed due to subsurface defects in the number one crankshaft connecting rod journal. 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). Engines that have been rebuilt by TCM will have a letter R at the end of the six digit numerical portion. Although this action is in the form of a final rule that involves requirements affecting flight safety and, thus, was not preceded by notice and an opportunity for public comment, comments are invited on this rule. If the engine is being disassembled does the estimate include testing after reassembly? But what is a prop strike and what exactly are the ramifications? 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. Teledyne Continental Motors has a slightly different approach, but not much different in practice. AC 43.13-1B has lots of general information in Chapter 8 on prop strikes. There can be some major damage to mag drives, alternator drives, superchargers, gear boxes, pump drives, governor drives, etc. 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. The $8,500 differential is not insignificant. It still could end up at a prop repair station if inspection deems it a prop major repair requirement depending on manufacturer inspection criteria of the prop. 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. That AD requires removing a core sample of material from the propeller mounting flange and sending the core sample to TCM for evaluation. Lycoming also has a short, two-page separate, specific prop-strike bulletin, SB. Dealing with them on this issue is fodder for another article, however. +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 - 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." In fact, the customers were sold their own crank. However the dates that the engines and crankshafts were delivered may not coincide with their dates of manufacture. Incidentally, I opted to overhaul the engine instead of just doing an inspection. Do we think the engine makers are overly eager to have you tear down or dig into your engine? Russell explains, "Aircraft operating under Part 135 of the FARs must comply with all manufacturer's service bulletins, and would have to comply with Service Bulletin 96-11 requiring total disassembly and inspection after any incident that required removal of the propeller for repairs or if the engine physically lost rpms during the incident. 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. Its also important to point out that this is not the only Lycoming bulletinthat discusses prop strikes. ", Airworthiness Directive 2004-10-14 is applicable to Lycoming engines that experienced a prop strike. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); WORLD'S PREMIER INDEPENDENT AVIATION NEWS RESOURCE. After defining a prop strike, TCM's SB 96-11A states: "A. Sun Sep 23, 2018 8:02 pm. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket. The bulletin reads as follows: At what point after a prop strike do you need an engine teardown and inspection? You will note TCM does not get into the concept of sudden stoppages possibly being handled differently as Lycoming does. It pretty much echoes the TCM service bulletin but adds two other situations. The specification material evaluation techniques have been improved to preclude a reoccurrence of this condition. A full overhaul will cost about $12,500 plus accessories. Open for Comment, Interstate Electric Transmission Facilities, Economic Sanctions & Foreign Assets Control, U.S. Some elbow room? This repetition of headings to form internal navigation links The one that came with the airplane had passed TBO (time between overhauls) but its logbooks didn't go back to when it came from the factory. 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. 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. So carefully consider all factors related to propeller strikes. 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. There are other things that have to be checked, including the magnetos, propeller governor, and fuel system. Both Lycoming and Continental have very specific requirements for disassembly and inspection. documents in the last year, 946 Comments may also be sent via the Internet using the following address: [email protected]. Comments sent via the Internet must contain the docket number in the subject line. This document has been published in the Federal Register. And what's a "solid object?" Now I had to determine the consequences. O-435, and TIO-541 series engines being exempt. (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). This is a minor or major prop repair issue, but not a potential engine tear down issue. The engine for sale was the model I needed, with about 1,000 hours since a factory overhaul. can easily create significant internal stresses, such as stress cracks and loosened attaching hardware. 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. Others are not necessarily so forthcoming, so reliable conclusions are difficult to draw. 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. Actually they are fairly consistent. These can be useful Comments for inclusion in the Rules Docket must be received on or before January 26, 2001. There is another FAA document with additional specifics for many Lycoming engines, and this is found in AD 2004-10-14, which defines and differentiates a prop strike and sudden prop stoppage and references Lycoming SB 475C, Jan 2003 as the supporting manufacturer document for the inspection and applicable engines. I've heard that a Continental doesn't require a tear down and inspection as a Lycoming does, but looking at Continental's Service Bulletin SB96-11B it looks Home. 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. In addition, propeller strikes also include situations where an aircraft is that agencies use to create their documents. You can find the Service Bulletins for Continental Aerospace Technologies Type Certificated Gasoline Engines below. Posted at 11:12h in don franklin oil change somerset ky by royal Sensenich Wood Propeller Co. 2008 Wood Court Plant City, FL 33563. At Unlimited Aero Engines we know that things happen, and happen fast. 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. 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. documents in the last year, 1487 00-29496 Filed 11-24-00; 8:45 am], updated on 4:15 PM on Tuesday, January 17, 2023, updated on 8:45 AM on Tuesday, January 17, 2023, 142 documents On numerous occasions, Textron Lycoming has been consulted about recommendations on whether to continue using an aircraft engine that has been involved We like to think that those we deal with are honest, however, there's a chance of impropiety by a seller, so when buying an airplane, be careful. Lycoming, in their prop-strike Service Bulletin 533A, takes the approach that the safest procedure is to take the engine apart for inspection following any incident involving propeller blade damage. PROPELLER STRIKE INSPECTIONS. Talking about whether to have the engine overhauled or just inspected, Tunnel said it can be penciled out. the material on FederalRegister.gov is accurately displayed, consistent with 533 called "Recommendations Regarding Accidental Engine Stoppage, Propeller/Rotor Strike or Loss of Propeller/Rotor Blade or Tip.". Kiss the old days goodbye. 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. I spoke with several shop owners and asked their opinion. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 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. 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. As for whether the inspection should be done, Anderson said he couldn't answer for anyone but himself; however, he wouldn't hesitate if it were his engine. continental prop strike ad. documents in the last year, 12 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 prop strike ad continental prop strike ad. 2000-NE-16-AD, 12 New England Executive Park, Burlington, MA 01803-5299. Inspect all engine accessories in accordance with the manufacturer's instructions.". Service Bulletin 533A has the pertinent Lycoming prop-strike definitions for all Lycoming direct drive engines. And anyway, who needs NOTAMs? Contact TCM to obtain additional rotobroach bits. This feature is not available for this document. Their decision would involve the specific engine involved, the severity of the prop damage, the cost, the time on the engine, whether the prop was stopped or appreciably slowed, who was flying at the time, what else is going on in the shop, and maybe the time of year and their mother's maiden name. The Public Inspection page may also Although not a guarantee of any kind, the lack of movement showed that utter destruction had not occurred. Lycoming's Service Bulletin 475B requires that in the event that the engine has experienced a propeller strike, inspection and possible rework of the accessory gear train as well as the rear of the engine's crankshaft is required. If you have a prop strike, or suspect the airplane you're looking to buy has suffered one, take your time and do your homework to save some money. 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. Counts are subject to sampling, reprocessing and revision (up or down) throughout the day. (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. For those engines that were overhauled in the field with factory new crankshafts, the crankshaft SN should be shown in work orders, log books or other maintenance records. According to the salvage yard, the prop strike came about after an out-of-fuel landing on a road in Louisiana. 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. 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). documents in the last year, 117 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. 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. 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." John Schwaner, author of the Sky Ranch Engineering Manual, a must have for all those interested in aircraft engines, and owner of Sacramento Sky Ranch, in Sacramento, California, said the quandary is, "How do you know if something is good or not?
