Airworthiness Directives; BRP-POWERTRAIN GMBH & CO KG Rotax Reciprocating Engines

We are adopting a new airworthiness directive (AD) for BRP-- POWERTRAIN GMBH & CO KG Rotax 914 F2, 914 F3, and 914 F4 reciprocating engines. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as isolated manufacturing deviations reportedly found on the threads of a certain batch of fuel pressure regulators, part number (P/N) 887130, installed on Rotax 914 F series engines, which could result in fuel leakage during engine operation. We are issuing this AD to prevent fuel leaks, which could result in an in-flight fire and damage to the aircraft.
