Big Airworthiness Directive Hits Lycoming Owners

Lycoming 360-Series Engines Affected

We knew it was coming... and it looks like it's here: a massive new Airworthiness Directive, affecting nearly 300 Lycoming 360-series engines, installed on a variety of single-and-twin-engine aircraft.

The AD, which requires owners to install new crankshafts in the affected engines, comes after a crankshaft failure was reported on a Lycoming LO–360. The directive, issued Thursday, also affects owners of AEIO–360, IO–360, O–360, and LIO–360 series reciprocating engines -- in all, an estimated 282 engines.

The FAA estimates each engine will need approximately 85 hours of labor to replace -- which, including parts and factoring labor costs of $65 per hour, amounts to total costs of about $15,300 per engine.

The FAA says it will cost US flyers more than $5.8 million to comply with the new AD.

Some better news, though -- the FAA also states Lycoming has said it intends to supply the new parts at no charge -- and will reimburse labor costs for engine removal and reinstallation "when authorized."

That should save pilots some lot of money -- and we certainly hope so, as this may be just the first in a series of new ADs affecting Lycoming owners.

Earlier this month, Aero-News reported on SB 569, a service bulletin issued on over 5,000 Lycoming crankshafts in engines ranging from the 360 series through IO-720s. The Aircraft Owners and Pilots association has urged Lycoming to cover all costs to owners affected by the bulletin... especially if, as seems likely, the bulletin becomes an Airworthiness Directive.
