Peter Germano, 45, of Moorestown, N.J. who had worked for USAir since February 1981. However, two parameters recorded were crucial: the aircraft's heading and the pitch-control yoke position. On that sunny Thursday, USAir Flight 427 from Chicago crashed while on approach to Pittsburgh International Airport. [12] The NTSB remarked that no airline had ever trained a pilot to properly recover from the situation experienced by the Flight 427 pilots and that the pilots had just 10 seconds from the onset of the roll to troubleshoot before recovery of the aircraft was impossible.

The exact mechanism of the failure involved the servo valve, which remains dormant and cold for much of the flight at high altitude, seizing after being injected with hot hydraulic fluid that has been in continuous action throughout the plane. Berkman's case settled for $25.2 million, while Van Bortel's was resolved for $6 million, according to Demetrio. Trying to counteract sharply rising G-forces, Germano yelled "Pull!"

[1][11] The FDR revealed that after the aircraft stalled, the plane and its occupants were subjected to a load as high as 4 g throughout the dive until impact with the ground in an 80-degree nose-down attitude at approximately 300 mph under significant sideslip. The rudder surface most likely deflected in a direction opposite to that commanded by the pilots as a result of a jam of the main rudder power control unit servo valve secondary slide to the servo valve housing offset from its neutral position and overtravel of the primary slide.[1]:ix. This raised the aircraft's angle of attack, removed all aileron authority, prevented recovery from the roll induced by the rudder and caused an aerodynamic stall. [14], USAir submitted to the NTSB that pilots should receive training with regard to a plane's crossover speed and recovery from full rudder deflection.
