New AD Issued for Lycoming Engines

The FAA has issued a new airworthiness directive (AD) for all Lycoming TIO-540-AJ1A reciprocating engines that went into effect June 28, 2017. The AD, which was prompted by several reports of engine exhaust leaks, requires initial and repetitive inspections of engine exhaust system weld joints and torque checking the exhaust pipe flange mounting nuts. The FAA estimates the AD will affect 758 engines installed on airplanes of U.S. registry. For more details, click here.
