Airworthiness Directives; Fokker Model F.27 Mark 050 Airplanes
type: Action
additional type: https://schema.org/LegalForceStatus
description: The FAA is superseding an existing airworthiness directive (AD) that applies to certain Fokker Model F.27 Mark 050 airplanes. The existing AD currently 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 new AD retains the requirements of the existing AD. This AD also requires replacing the outlet port (high-pressure) bobbin with a new, improved outlet port (high-pressure) bobbin, which terminates the repetitive visual checks and inspections. 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.
