Probable cause

The dual student pilot's improper use of the aircraft power plant controls, resulted in a complete loss of engine power.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The instructor pilot was giving training to a commercial pilot who was preparing to renew his instructor's license. The instructor was giving his student a simulated forced landing. During the descent the engine was cleared only once. When the throttle was advanced for a go-around the engine failed to respond. The aircraft landed on unsuitable terrain and nosed over.
