Analysis

Plt stated after accident that while on final approach with eng pwr reduced for landing, the acft began to descend below the desired glidepath. When the throttle was advanced there was no added thrust. An in-flight restart was unsuccesful. The acft landed short of the runway an collided with a dirt embankment. Post crash functional test of the eng revealed no evidence of a mechanical malfunction or failure that would preclude normal eng operation. The eng did fail when the mixture control was set for smooth eng operation, the boost pump was in the off position and the throttle rapidly advanced from a low pwr setting to full pwr.
