"Possible AD Looms For Lycoming Owners Affected By Latest Service Bulletin
Calls For "Retirement" Of 5,000+ Crankshafts
Two-hundred-million dollars. That's the current price tag on Textron/Lycoming's effort to, in the company's words, "proactively retire" thousands of engines with potential crankshaft problems. Now, Lycoming has announced yet another bulletin -- SB 569, which calls for replacement of over 5,000 crankshafts on engines ranging from the O-360 to the IO-720.
Unlike earlier service bulletins, however, the latest warning from Lycoming affects crankshafts that, to the company's knowledge, haven't failed to perform as designed -- and that rubs the Aircraft Owners and Pilots Association the wrong way.
"Even Lycoming concedes that there have been no failures with these crankshafts," said Luis Gutierrez, AOPA director of regulatory and certification policy. "The FAA needs to do its homework and ensure that there is compelling, risk-based data to support what will be an expensive proposition for owners."
SB 569 calls for the crankshaft to be replaced whenever the crankcase is opened, the engine overhauled, or within three years, whichever comes first. That's not the worst of it, though: unlike previous ADs where the company paid all expenses for replacing the crankshaft, Lycoming is only offering to provide a $2,000 "crankshaft kit." If the SB requirements are written into an AD, AOPA reports owners could face a $6,000 to $7,000 bill within three years.
While it's customary for the FAA to solicit user input and experience before issuing an AD, the agency has not yet done that. However, the Wall Street Journal reports the FAA is preparing to step in and make all Lycoming service bulletins related to crankshafts into Airworthiness Directives.
Already, Lycoming has set aside $190-million -- most of it insurance money -- to deal with the existing problems found in crankshafts for a wide range of aircraft.
Textron has tried to recoup some of its money already on the crankshaft debacle, by suing the company that made the defective parts -- Interstate Southwest, Ltd of Navasota, TX. In a strange legal twist, however, the judge ordered Textron to pay Interstate $96 million in damages -- after the jury found that Textron defrauded Interstate by hiding design defects and other problems with its engines.
That verdict is now under appeal. Meanwhile, Lycoming owners are on the edge of their seats, awaiting word on whether the latest service bulletin will result in an Airworthiness Directive.
AOPA is "strongly urging" the FAA to go through the Airworthiness Concern Sheet (ACS) process, which allows the FAA to consult with owner groups and type clubs to obtain operational data on crankshaft problems, and consider alternatives before issuing an AD. Such a directive would hit owners with a $35 million bill for repairs, according to the association.
AOPA also argues that if crankshaft replacement is warranted, it should be based on time in service -- rather than an arbitrary calendar time. "The FAA seems to be receptive to that," said Gutierrez, "and that would have a real cost of ownership benefit for most private aircraft owners."
"In three years, some owners may still have less than 500 hours on their crankshafts," said Gutierrez. "That is why it is essential that any retirement scheme not be arbitrary but based on solid data that indicates when the failures are likely to occur."
AOPA will also be urging Lycoming to provide the same kind of benefits to owners as it has with the previous ADs -- namely, covering the costs of compliance."

egg: "eggenfellner aircraft, this is jan"
chad: "good morning jan! i'd like to order an H-6 today"
jan: "it's about time, chad!"
chad: "i know, i know...i need an engine that won't cost me another 6-8 grand in a few years because of an SB or AD"
jan: "an H-6 is on it's way for you!"
) And everytime I talk to someone really knowledgable about airplane engines, they always say, "don't use an automotive engine". I heard somethind like that from Mr. VanGrunsven himself. But this has been seconded, and thirded, by others.
