## Analysis

DURING TAKEOFF ROLL, FULL THROTTLE WAS APPLIED TO BOTH ENGINES BUT THE LEFT ENGINE WAS SLOW TO RESPOND. WHEN FULL PWR WAS NOT REACHED, THE FLIGHT WAS ABORTED. THE ACFT CONTINUED TO ROLL OFF THE DEPT END OF THE RWY AND DOWN A RAVINE. THE PLT STATED THAT ON THE PRIOR FLIGHT HE NOTED THAT THERE WAS AN APPROX 100 RPM DROP ON BOTH MAGS IN THE LEFT ENGINE AND THE MANIFOLD PRESSURE WAS SLOW TO RESPOND TO THROTTLE COMPARED TO THE RIGHT ENGINE. THE ACFT WAS ON THE GROUND FOR OVER 6 HOURS BEFORE TAKEOFF ON THE ACCIDENT FLIGHT.
