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.
