Airworthiness Directives; Fokker Model F27 Mark 050 Airplanes

الملخص

The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F27 Mark 050 airplanes. This AD requires repetitive visual checks for oil leaks of both engines between the spinner and the engine cowling, and directly behind the heated intake lip of the engine; repetitive inspections for oil leaks at the feathering pump on both engines; and corrective actions if necessary. This AD results from reports of oil leakage at the engine feathering pump. We are issuing this AD to prevent oil loss from the feathering pump, which could cause the engine to shut down in flight.
