Airworthiness Directives; Fokker Model F28 Mark 0100 Series Airplanes

Riepilogo

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 97-19-16, that was sent previously to all known U.S. owners and operators of Fokker Model F28 Mark 0100 series airplanes equipped with Rolls-Royce Tay 650-15 engines, by individual notices. This AD requires a revision to the FAA- approved Airplane Flight Manual (AFM) to include procedures to prohibit use of reverse engine thrust power settings between idle and emergency maximum; and submission of a report to the airplane manufacturer. This action is prompted by a report that, during preparation for takeoff, an engine fan blade failure occurred, followed by an engine fire. The actions specified by this AD are intended to prevent uncontained engine fan blade failure due to high cycle fatigue cracking, which could result in loss of thrust from the affected engine and secondary damage to aircraft and/or fire.
