The FAA last Thursday made final the proposed Airworthiness Directive it issued last December affecting almost 300 crankshafts in Lycoming engines. (This AD was proposed prior to the latest Lycoming Service Bulletin that "retires" some 5,100 crankshafts.) No comments were received, the FAA said, so it will adopt the AD as proposed. "Lycoming has said that it will supply the new parts free of charge, pay for the shipping, and pay for the labor cost of removing and reinstalling the engines," said Luis Gutierrez, AOPA's director of regulatory and certification policy. "This will help soften the blow to aircraft owners and help save them a substantial amount of money." (Similar financing may not apply to owners of the 5,000 crankshafts to be retired.) Owners must comply within six months or 50 hours of time in service from the time the AD takes effect on April 27. The AD is the latest FAA action in a series of crankshaft problems in Lycoming engines.
