Airworthiness Directives; Fokker Services B.V. Airplanes

Короткий зміст

We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This AD was prompted by an in-flight failure of the hydraulic control panel, which resulted in the absence of pressure and quantity indication of the hydraulic system and accompanying alerts for "hydraulic system 1 low quantity" and "hydraulic system 2 low quantity." This AD requires implementing new abnormal procedures for hydraulics in the airplane flight manual (AFM). We are issuing this AD to prevent loss of control of the airplane due to incorrect hydraulic system failure information being provided to the flightcrew, followed by application of inappropriate procedures.
