01/17/2023, 823 And what's a "solid object?" In addition, propeller strikes also include situations where an aircraft is 01/17/2023, 159 (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. Use the PDF linked in the document sidebar for the official electronic format. To start my investigation, I wanted the official definition of a prop strike. the most are "prop strike." documents in the last year, 534 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 There may be other additional requirements mandated by insurance policies or engine manufacturer and/or overhauler warranty. Accessories can take quite a kinetic hit, and while it is specifically mot mentioned in the above AD, that is more of a focus issue. Are there any hidden costs? (iii) Maintain a record of each core sample obtained with each rotobroach bit used. Document Drafting Handbook These cases should be handled as sudden stoppages because of potentially severe side loading on the crankshaft flange, front bearing, and seal.". Others are not necessarily so forthcoming, so reliable conclusions are difficult to draw. Since an unsafe condition has been identified that is likely to exist or develop on other engines of this same type design, this airworthiness directive (AD) requires removing a core sample of material from the propeller mounting flange and sending the core sample to TCM for evaluation. on Issued in Burlington, Massachusetts, on November 13, 2000. If you've attended AirVenture or any of the other major airshows, you've heard it. TCM is less equivocal. I spoke with several shop owners and asked their opinion. 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). 12866. AC 43.13-1B has lots of general information in Chapter 8 on prop strikes. Removing and reinstalling a propeller take just a few hours, and the prop shops don't care who brings the job through the door. We dont have such trust unless we know a whole lot about who we are dealing with and have all the proper logs and background checks-especially in the Internet age there is no excuse to not do a lot of digging on who and what you are dealing with. (f) This amendment becomes effective on December 12, 2000. 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? Includes: Fuel Injection Spyder Starter Alternator Bendix Magnetos Gamijectors I will be more than happy to ship this engine to you. 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. 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). 01/17/2023, 202 Most insurance carriers don't want to face the prospect of the engine or propeller leaving the aircraft due to a prop strike!". certain lots, of steel production or forming operations. Prop strike on Continental. 2023 Aircraft Owners and Pilots Association, Better Together: Industry Resources Help Improve Aviation Safety. Its also important to point out that this is not the only Lycoming bulletinthat discusses prop strikes. Unfortunately, disassembly and nondestructive testing procedures are the only way to provide a reasonable level of assurance that the engine is truly fit for continued service. 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? This could indicate a gear-up landing, or other source of damage that took time to fix. What this all boils down to is that in the case of any accidental damage to a propeller installed on a aircraft operating under Part 91 of the FARs, it is up to the inspecting mechanic to determine if the engine should continue in service without total disassembly and inspection, or only the SB 475C level of inspection if a Lycoming engine falls into that category. Note 10: 2400 hours TBO may apply. 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. better and aid in comparing the online edition to the print edition. documents in the last year, 37 As he approached the director of maintenance he asks, Pilot: "When does a prop strike require engine tear-down and inspection? 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. There used to be, but it was kind of informal and there was a lot open to interpretation. This proposed rule does not have federalism implications, as defined in Executive Order No. I took the other SR20 this time and it was also broken, to the point where it shouldn't have been flown. We can even see situations where a prop sustains a fairly nasty nick in a gravel strip, but no rpm loss occurs or serious blade damage occurs. 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. The documents posted on this site are XML renditions of published Federal Comments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. daily Federal Register on FederalRegister.gov will remain an unofficial All rights reserved. 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. 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. Propeller inspections are fairly clear cut damage on the blades is typically quite apparent, and the existence of damage beyond field repair limits dictates that the unit is disassembled and given a searching internal inspection, and in some cases, complete overhaul. 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. On severe prop strikes, the mounts can be easily twisted and loaded in a way that it was not designed to withstand," he says. Replace the rotobroach after the sixth core sample, or before if the rotobroach does not cut with the maximum torque applied. More than the prop and crankshaft 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. 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. In fact it is a very insidious situation since there is often no obvious damage-no harm, no foul so to speak. This article originally appeared in the December 2012 issue of Light Plane Maintenance. Putting the puzzle together 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). 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. 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 New posts Search forums. Counts are subject to sampling, reprocessing and revision (up or down) throughout the day. These markup elements allow the user to see how the document follows the So my question was, should I overhaul the present engine or look for one with good logs? 106(g), 40113, 44701. [FR Doc. Is the engine being completely disassembled and inspected? What you see in the pictures is what you are getting. 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. 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. 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 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. Its entirely possible after a sudden engine stoppage for there to be severe internal damage and yet the prop looks perfectly OK even if the prop was either totally stopped or the rpm dropped by the incident. 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." the most are "prop strike." O-435, and TIO-541 series engines being exempt. To comply with AD 2004-10-14, if it applies to your engine, the engine does not need to be completely disassembled and access to the accessory gear train can be accomplished, in most cases, with the engine still installed in the aircraft. It also does not equivocate to any degree on an engine tear down being the mandatory procedure, which is described in the bulletin. 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. All crankshafts that are found to be unserviceable must be replaced with a serviceable crankshaft prior to further flight. TCM has informed the FAA that it intends to maintain a 24 to 48 hour turn-around time for notification of the crankshaft airworthiness. Are any of the engines accessories inspected as they should be, and if so to what extent? Sensenich Wood Propeller Co. 2008 Wood Court Plant City, FL 33563. The opinions differ with each individual, and what maintenance technicians would do personally is quite often at odds with their professional opinions. Contact TCM to obtain additional rotobroach bits. 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. Its also important to point out that this is not the only Lycoming bulletinthat discusses prop strikes. There's also the cost of inspection of the accessories, which is extra. They were legitimate, having been initiated after an inspection, but that doesn't help when selling the airplane. 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. 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. has no substantive legal effect. establishing the XML-based Federal Register as an ACFR-sanctioned 01/17/2023, 249 (iv) Do not exceed the torque limits specified in TCM MSB 00-5C, dated October 10, 2000, when obtaining the core sample. 49 U.S.C. A propeller strike is dangerous, not only because it damages the propeller but also because it can 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. It pretty much echoes the TCM service bulletin but adds two other situations. 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. 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. Everyone was happy and the prices were right. After defining a prop strike, TCM's SB 96-11A states: "A. Airmark Overhaul, Inc. 6001 NW 29th Avenue Fort Lauderdale, FL 33309. The President of the United States communicates information on holidays, commemorations, special observances, trade, and policy through Proclamations. 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. the Federal Register. by the Federal Energy Regulatory Commission He continues, "T.C.M. Assistant Manager, Engine and Propeller Directorate, Aircraft Certification Service. Start dateSep 28, 2016. 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. Nitride hardened cranks have a greater tendency to crack, since the nitride hardened materials resist bending. 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. That said, we did an article a few years ago where an owner of an old Bonanza bought an IO-520 engine from another Bonanza engine owner who upgraded to a factory IO-550. 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. 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. Should he also have performed the obligatory engine inspections? For crankshafts identified in paragraph (a) of this AD, TCM has already determined which engines have a new suspect crankshaft installed and have identified those engines by engine SN. to a sudden stop. 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. If the engine is being disassembled does the estimate include testing after reassembly? 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. But what is a prop strike and what exactly are the ramifications? Docket 2000-NE-16-AD. Register (ACFR) issues a regulation granting it official legal status. This repetition of headings to form internal navigation links Does 500 rpm fit that bill? This feature is not available for this document. If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket. The alternator is turning 3000 rpm because of gearing. 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. Dialing in the flange is worthless for this. publication in the future. If you can imagine a loose rod banging around inside your engine, you know it's bad. Unfortunately, it may be the next owner who discovers any hidden damage. Now that I had a definition, what would I have to do about such an event? rendition of the daily Federal Register on FederalRegister.gov does not Located in Burlington, North Carolina, we provide an array of aircraft maintenance services, including engine, cylinder, and propeller overhaul and repair. documents in the last year, 973 of the issuing agency. This airworthiness directive (AD) applies to each engine identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. 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. offers a preview of documents scheduled to appear in the next day's 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 I alluded to the potential of buying an airplane that suffered a prop strike without the required inspections being completed. Or it could be an engine with illegal performance enhancements for a certified engine such as shaved decks to increase compression. Continued evaluation of crankshafts lots with serial numbers (SN's) other than those that were listed in AD 2000-08-51, has detected the same condition in those crankshaft lots. 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. Its not a smoking gun, but perusing the accident reports makes one wonder about such coincidences. Our designation as a Cessna Service Center and authorization as a parts and engine distributor for both Lycoming and Continental On Lycoming engines, which are not nitrided, the flange can be bent. The bulletin reads as follows: Kiss the old days goodbye. The President of the United States issues other types of documents, including but not limited to; memoranda, notices, determinations, letters, messages, and orders. K. kevmor99. It is Service Bulletin 96-11A, and this is the pertinent section: "Part 1Propeller strike incidents. 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. 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." Aircraft was involved in a prop strike. on 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. Each document posted on the site includes a link to the Submit comments in triplicate to the Federal Aviation Administration (FAA), New England Region, Office of the Regional Counsel, Attention: Rules Docket No. Compliance with this service bulletin is mandatory per AD 91-14-22. Inspect all engine driven accessories in accordance with the manufacturers maintenance instructions. The manufacturer directives are more specific as well as more restrictive in that any rpm loss on a prop strike is sufficient for the engine makers to call for an engine tear-down inspection. 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. Information about this document as published in the Federal Register. My investigation started with my need for another engine for my Cessna 210. They are often ignored in the prop-strike evaluation, yet they have prescribed inspection criteria even if involved in only a sudden stoppage. Register, and does not replace the official print version or the official A. 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. Basically the fuel gauges in the center console are shorting out.
