Abstract
We are adopting a new airworthiness directive (AD) for certain Lycoming TIO-540-AJ1A reciprocating engines. This AD was prompted by several reports of cracked engine exhaust pipes. This AD requires inspection of the engine exhaust pipes for cracks and replacement of the turbocharger mounting bracket. We are issuing this AD to prevent failure of the exhaust system due to cracking, which could lead to uncontrolled engine fire, harmful exhaust gases entering the cabin resulting in crew incapacitation, and damage to the airplane.
