Probable cause
Failure of the fuel pump control shaft because of improper machining by the repair facility during maintenance modification of the pump and improper procedures during overhaul of the nose landing gear.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
As engine power was increased for takeoff, the no. 1 engine accelerated beyond target epr. Engine shut down had to be done with the fuel shut off lever. The asymmetric thrust was controlled with nose wheel steering. Before the airplane could be stopped the nose wheels separated from the landing gear. The investigation revealed that the fuel pump output spline to the fuel control had stripped. It occurred at such a time that the fuel control sensed an underspeed & increased fuel flow. Misalignment of the spline shaft resulted from improper machining during pump modification. The nose gear inner cylinder failed in fatigue in an area of excessive grinding during overhaul.
