Description

The FAA is issuing a new airworthiness directive (AD) for certain Tecnam Model P2010 airplanes equipped with Lycoming IO390 engines. This AD addresses an unsafe condition caused by potential failure of the exhaust muffler flame tube, which could lead to unrecoverable loss of engine power and loss of control. It requires repetitive detailed borescope inspections of the exhaust muffler flame tube and, if cracks or fractures are found, repairs must be made using FAA or EASA approved methods. An optional terminating action involves revising the aircraft maintenance program to include specific Tecnam maintenance manual supplements.
