Full official abstract

We are adopting a new airworthiness directive (AD) for all Lycoming TIO-540-AJ1A reciprocating engines. This AD requires initial and repetitive inspections of engine exhaust system weld joints and torque checking the exhaust pipe flange mounting nuts. This AD was prompted by several reports of engine exhaust leaks. We are issuing this AD to correct the unsafe condition on these products.
