Probable cause & findings

THE MECHANIC'S IMPROPER USE OF ANTI-SEIZE COMPOUND ON THE INJECTOR NOZZLE THREADS WHICH RESULTED IN AN ENGINE FAILURE.

Factual narrative

DURING TAKEOFF, THE AIRPLANE'S ENGINE LOST POWER WHICH RESULTED IN INADEQUATE POWER TO CLEAR TREES LOCATED AT THE END OF THE RUNWAY AND IN THE AIRPLANE'S FLIGHT PATH. THE INVESTIGATION REVEALED THAT AT THE LAST ANNUAL INSPECTION A MECHANIC REPLACED THE FUEL INJECTOR NOZZLES USING AN ANTI-SEIZE COMPOUND ON THE THREADS. THE ANTI-SEIZE COMPOUND WORKED ITS WAY INTO THE NUMBER 1 CYLINDER FUEL INJECTOR NOZZLE THREW THE HOLES AND BLOCKED THE FLOW OF FUEL TO THE CYLINDER.
