## Analysis

THE ACFT WAS ON A TEST FLT AFTER A TOP-OVERHAUL HAD JUST BEEN COMPLETED. MECHANICS RPRTD THAT BEFORE THE FLT, THE ENG HAD BEEN PROPERLY RIGGED & OPERATED NORMALLY DRG RUN-UP. DRG INITIAL CLIMB AFTER TAKEOFF, WITNESSES SAID THE ENG LOST POWER. THE PLT INITIATED A STEEP (70-75 DEGREE BANKED) TURN BACK TOWARD THE ARP. DRG THE TURN, THE NOSE DROPPED & THE ACFT IMPACTED THE GROUND IN A LEFT WING LOW, NOSE DOWN ATTITUDE. THE ACFT WAS EXTENSIVELY DAMAGED BY IMPACT & GROUND FIRE. A TEARDOWN OF THE ENG REVEALED INTERNAL ENGINE MECHANICAL CONTINUITY, EVIDENCE OF OIL PUMP OPERATION, AND NORMAL LUBRICATION. THE DUAL MAG HAD EXTENSIVE FIRE DMG. THE FUEL PUMP WAS CHARRED; INVESTIGATORS WERE UNABLE TO ROTATE DRIVESHAFT. TEARDOWN DID NOT CONFIRM REASON FOR POWER LOSS.
