What happened
During takeoff, the pilot reported that the right engine lost power as the aircraft was climbing through approximately 50 feet AGL. In response to the power loss, the pilot elected to shut down both engines and abort the takeoff. The aircraft landed with the landing gear retracted and subsequently skidded off the right side of the runway.
The investigation
An examination of the right engine revealed heavy sooting on the spark plugs and the exhaust system. When the right engine was restarted following the accident, it initially ran roughly, exhibited a rich mixture, and produced black smoke from the exhaust. Investigators noted evidence of excessive fuel pressure.
Following the replacement of the fuel injector pump, the engine returned to normal operation. An inspection of the failed pump revealed that the low-pressure adjustment bolt could be rotated by hand. Upon disassembly of the pump, it was discovered that the internal lock nut was worn and unserviceable.
Maintenance records indicated that engine problems had been reported on previous flights. On June 21, 1989, the right engine's turbocontroller and fuel pump were adjusted for both high and low pressures. However, the procedures used at the maintenance facility for turbocharged engines were not in accordance with Teledyne Continental Service Bulletin M89-10.
