Détails:
The no. 1 engine accelerated beyond target EPR on takeoff. The crew aborted the takeoff, but the no. 1 engine didn't respond to the retarded power lever, so had to be shut down with the fuel shut-off lever. Asymmetric thrust was controlled with nose wheel steering. The nosegear wheels separated from the gear before the aircraft was brought to a halt.
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."
