The FAA has issued a Notice of Proposed Rulemaking on Lycoming 540 and 360 series engines that were the subject of a company Service Bulletin and recall two weeks ago. The good news, according to AOPA, is that parts are in stock and the fully funded repairs of the 1,128 engines shouldn't take too long. Lycoming is estimating the engines will be in their shop for 10 days and the rest of the down time is dependent on the removal and re-installation. The FAA didn't issue an Emergency AD on the engines, which have suffered 12 crankshaft failures in the past five years. The NPRM comment period goes until Aug. 22 and then owners have 50 hours or six months, whichever comes first, to comply. "Three years ago, Lycoming did a good job, in most cases, in covering reasonable expenses and getting claims processed," AOPA spokesman Woody Cahall said. "But owners should let us know (1-800-872-2672) if they encounter any problems."
