However the dates that the engines and crankshafts were delivered may not coincide with their dates of manufacture. from 54 agencies. Some elbow room? Until the ACFR grants it official status, the XML SUMMARY: The FAA is adopting a new airworthiness directive (AD) that supersedes an existing AD, for Lycoming Engines (formerly Textron Lycoming), direct-drive 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? Basically anything that moves is subject to visual and other forms of nondestructive testing. But if there's 1,000 hours or more left on the engine, you're probably better off with just an inspection. (2) Any incident during engine operation in which the propeller impacts a solid object that causes a 552(a) and 1 CFR part 51. These tools are designed to help you understand the official document 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. documents in the last year, by the Transportation Security Administration 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. Unfortunately, it had experienced a prop strike. The pins are more than adequate for running loads, but they are totally inadequate when you subject them to sudden stoppage. include documents scheduled for later issues, at the request The FAA definition of a sudden stoppage, is the engine stopping suddenly in under one rpm. Lycoming has reports of ground strikes, which have resulted in overstressed connecting rod bolts, that failed later. 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. At what point after a prop strike do you need an engine teardown and inspection? for better understanding how a document is structured but A propeller strike can occur at taxi speeds and during touch-and-go operations with propeller tip ground contact. 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. On numerous occasions, Textron Lycoming has been consulted about recommendations on whether to continue using an aircraft engine that has been involved 2023 Endeavor Business Media, LLC. documents in the last year, 117 Refer McCauley Service Bulletin 137W.

(iii) Maintain a record of each core sample obtained with each rotobroach bit used. 600-ft lb load on the crank gear on a sudden stop from 1000 engine rpm. It pretty much echoes the TCM service bulletin but adds two other situations. (iv) Do not exceed the torque limits specified in TCM MSB 00-5C, dated October 10, 2000, when obtaining the core sample. the Federal Register. 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. I bought the engine and started my quest to determine what I absolutely had to do to get the airplane airworthy. Inspect all engine driven accessories in accordance with the manufacturers maintenance instructions. on 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 is Service Bulletin 96-11A, and this is the pertinent section: "Part 1Propeller strike incidents.

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. 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. (ii) You may use each rotobroach bit to obtain up to six core samples. 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. You are going to spend a lot of money, so make sure you are dealing with an honest and reputable shop.

The FAA has reviewed and approved the technical contents of TCM Mandatory Service Bulletin (MSB) 005C, dated October 10, 2000. This condition, if not corrected, could result in crankshaft connecting rod journal fracture, which could result in total engine power loss, in-flight engine failure and possible forced landing. I watched the video and figured the pilot had reduced power before hitting the ditch. (2) Any incident during engine operation in which the propeller impacts a solid object that causes a drop in revolutions per minute (RPM) and also requires structural repair of the propeller (incidents requiring only paint touch-up are not included). Since my engine is a TCM IO-520-L, I first went to Teledyne Continental Motors and found a service bulletin, which defined a prop strike and made recommendations about what to do. the official SGML-based PDF version on govinfo.gov, those relying on it for Compliance with this service bulletin is mandatory per AD 91-14-22.

Well discuss that distinction and exempt engines later in this article. This is a minor or major prop repair issue, but not a potential engine tear down issue. Service Bulletin 533A has the pertinent Lycoming prop-strike definitions for all Lycoming direct drive engines. This table of contents is a navigational tool, processed from the 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). 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. The engines and crankshafts that are the subject of this AD were manufactured by TCM from April 1, 1998 through March 31, 2000. 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. provide legal notice to the public or judicial notice to the courts.

These are the requirements as we see them. 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. documents in the last year, 534 developer tools pages. 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.
