This article originally appeared in the December 2012 issue of Light Plane Maintenance. This amendment is prompted by reports of crankshaft failures, and by the addition of additional crankshaft serial numbers (SN) that have been added to the suspect population. The thought of the damage and cost involved makes all of us shudder. establishing the XML-based Federal Register as an ACFR-sanctioned Includes: Fuel Injection Spyder Starter Alternator Bendix Magnetos Gamijectors I will be more than happy to ship this engine to you. 600-ft lb load on the crank gear on a sudden stop from 1000 engine rpm. 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. Another problem area is in engines with crank counterweights, a very common design. 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. 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. For example, how much propeller filing constitutes "minor dressing?" There's a tremendous amount of energy stored in the rotating flyweight, and when all of a sudden you stop the prop and engine, that energy has to be dissipated somewhere.". All of the fractures have been grouped around certain manufacturing dates between April 1, 1998, and March 31, 2000, inclusive. Following any propeller strike, complete disassembly and inspection of all rotating engine components is mandatory and must be accomplished prior to documents in the last year, 28 The authority citation for part 39 continues to read as follows: Authority: The actions are required to be accomplished in accordance with the service bulletin described previously. Nitride hardened cranks have a greater tendency to crack, since the nitride hardened materials resist bending. regulatory information on FederalRegister.gov with the objective of Note 10: 2400 hours TBO may apply. Compliance with this service bulletin is mandatory per AD 91-14-22. Kiss the old days goodbye. So, when it comes time for that prop strike/sudden. Continental Properties has earned a spot on the National Multifamily Housing Council's (NMHC) list of the Top 10 developers in the country. 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). 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. 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. 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. (2) Any incident during engine operation in which the propeller impacts a solid object that causes a Issued in Burlington, Massachusetts, on November 13, 2000. In another incident a prop hit a small rock, which had been dislodged and thrown back by a larger aircraft. corresponding official PDF file on govinfo.gov.

AOPA Members DO more LEARN more SAVE more - Get MORE out of being a pilot -. The opinions differ with each individual, and what maintenance technicians would do personally is quite often at odds with their professional opinions. (c) Crankshaft material inspections (crankshaft propeller flange core samples) that were done using TCM MSB 00-5, dated April 14, 2000; MSB 00-5A, dated April 28, 2000; or MSB 00-5B, dated May 25, 2000, comply with this AD and must not be repeated. 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. Propeller strike inspections. And what's a "solid object?" Register, and does not replace the official print version or the official Information about this document as published in the Federal Register. Does 500 rpm fit that bill? 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. Studies have shown that a 100-amp alternator can impose a. Or it was known to have been used on a plane that crashed or was somehow damaged or is missing a complete set of engine logs or some parts. 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. documents in the last year, by the Veterans Affairs Department 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. These counterweights move on relatively soft bushings. 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. [FR Doc. New posts Search forums. My investigation started with my need for another engine for my Cessna 210. 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. documents in the last year, by the Transportation Security Administration Recent changes in the approach to propeller strikes dictated by Airworthiness Directives, engine manufacturer Service Letters, and insurance company policy have made anything less than a thorough teardown and NDT inspection unacceptable. 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. This Airworthiness Directive (AD) is applicable to Teledyne Continental Motors (TCM) 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 that were assembled, rebuilt, or overhauled using a crankshaft that was manufactured between April 1, 1998, and March 31, 2000, listed by engine and crankshaft serial number (SN) in TCM Mandatory Service Bulletin (MSB) 00-5C, dated October 10, 2000. 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. 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. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket. In short, all accessories become suspect to damage under either a prop strike or sudden stoppage incident. documents in the last year, 534 as a result of sudden stoppage. 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. 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. 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. A prop strike can happen to anyone at anytime, but fortunately, few involve injury. That said, you'll understand that this article isn't going to state, or even hint at, what you should do in this situation. documents in the last year, 12 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. The argument goes would you rather be paying for an in flight engine failure 100 hours from now. Inspect all engine accessories in accordance with the manufacturer's instructions.". A Rule by the Federal Aviation Administration on 11/27/2000. In many instances prop strikes will fall into the major repair category, which necessitates repair station or manufacturer repair of the prop (if needed). So carefully consider all factors related to propeller strikes. "You naturally think of the crankshaft and things that are directly connected to the engine, but you don't think of other accessories. Should he also have performed the obligatory engine inspections? documents in the last year, 37 on FederalRegister.gov karen rietz baldwin; hidden valley high On numerous occasions, Textron Lycoming has been consulted about recommendations on whether to continue using an aircraft engine that has been involved Refer McCauley Service Bulletin 137W. 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 Click here for the Diesel Engines service bulletins. 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). (iv) Do not exceed the torque limits specified in TCM MSB 00-5C, dated October 10, 2000, when obtaining the core sample. Although not a guarantee of any kind, the lack of movement showed that utter destruction had not occurred. (ii) You may use each rotobroach bit to obtain up to six core samples. 552(a) and 1 CFR part 51. Emergency AD 2000-08-51 was sent to all known U.S. owners and operators of Teledyne Continental Motors (TCM) 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 by individual letters. 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. The President of the United States communicates information on holidays, commemorations, special observances, trade, and policy through Proclamations. Are any of the engines accessories inspected as they should be, and if so to what extent? FIND A DEALER. So my question was, should I overhaul the present engine or look for one with good logs? 2000-NE-16-AD, 12 New England Executive Park, Burlington, MA 01803-5299. At what point after a prop strike do you need an engine teardown and inspection? This site displays a prototype of a Web 2.0 version of the daily The engine SN can be found in logbooks or other maintenance records. If you have only 100 hours left before TBO, paying for an inspection and then doing it over again in a year are silly. 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 Are the minimum legal requirements being met? Document page views are updated periodically throughout the day and are cumulative counts for this document. TCM has informed the FAA that it intends to maintain a 24 to 48 hour turn-around time for notification of the crankshaft airworthiness. 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. (ii) If TCM notifies you that the crankshaft is serviceable, the propeller assembly may be reinstalled. ", Case in point Basically the fuel gauges in the center console are shorting out. This repetition of headings to form internal navigation links Other Lycoming literature mentions the importance to check the accessories as does TCM. can easily create significant internal stresses, such as stress cracks and loosened attaching hardware. 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. For more than three decades, customers have trusted their airplanes to Triad Aviation, Inc. 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. Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed. (3) A sudden RPM drop while impacting water, tall grass, or similar yielding medium, where propeller damage is not normally incurred. These tools are designed to help you understand the official document has no substantive legal effect. While every effort has been made to ensure that Dye Penetrant test didn't show any cracks on the flange, runout is .001 which is well within tolerance. During the subsequent takeoff, the airplane's right wing hit the mirror of a semitruck, which veered the airplane into a fire truck and eventually a ditch. Engine inspection requirements after prop strikes can become complicated, however, and the regulations and recommendations seem to overlap and intertwine. Inspect all engine driven accessories in accordance with the manufacturers maintenance instructions. 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. He adds, "This limits their liability exposure. continental prop strike ad. 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. Everyone was happy and the prices were right. documents in the last year, 90 on 12866. 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. (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. 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. documents in the last year, 1487 More information and documentation can be found in our 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. 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. ", Airworthiness Directive 2004-10-14 is applicable to Lycoming engines that experienced a prop strike. 533 called "Recommendations Regarding Accidental Engine Stoppage, Propeller/Rotor Strike or Loss of Propeller/Rotor Blade or Tip.". On Lycoming engines, which are not nitrided, the flange can be bent. Consider the accessories. However the dates that the engines and crankshafts were delivered may not coincide with their dates of manufacture. You will note TCM does not get into the concept of sudden stoppages possibly being handled differently as Lycoming does. are not part of the published document itself. documents in the last year, 41 Recently, a transient aircraft hit a rubber traffic cone with the prop and kept going, taking off and disappearing into the western sky. 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. by the Federal Energy Regulatory Commission documents in the last year, by the Federal Communications Commission A propeller strike can occur at taxi speeds and during touch-and-go operations with propeller tip ground contact. TCM is less equivocal. Plus, unless you were watching the tach, how would you know? 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. FAA# JL4R288M | EASA.145.4115 | Toll Free: 800-282-3202 | 954-970-3200 But what is a prop strike and what exactly are the ramifications? According to DeJoris, "Hartzell requires hub replacement if any blade in the assembly is bent beyond repair limits due to impact damage. and services, go to The concern, of course, is the prospect of hidden damage, which can cause, and has caused, subsequent engine failures. Comments for inclusion in the Rules Docket must be received on or before January 26, 2001. 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. 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. Is the engine being completely disassembled and inspected? The general consensus is that at least some degree of tear-down is the only safe option under their definition, and largely follows manufacturer data in the general damage/repair evaluation techniques. better and aid in comparing the online edition to the print edition. Disregard the letter R.. 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. Its not a smoking gun, but perusing the accident reports makes one wonder about such coincidences. 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. Basically anything that moves is subject to visual and other forms of nondestructive testing. 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. 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. , since the nitride hardened materials resist bending one with good logs experienced a prop hit a small rock which!
