Incident Overview
A flight instructor reported that during level cruise, the engine RPM suddenly decreased from 2300 to 1800. The power level became insufficient to maintain flight, necessitating a forced landing.
Forced Landing
The instructor selected a dry river wash in mountainous terrain as the only suitable landing area. The soil in the wash was soft. Upon touchdown, the nose gear dug into the soft soil, causing the aircraft to nose over.
Post-Accident Inspection
FAA inspectors examined the aircraft and discovered that the starter was engaged. No other system abnormalities were found.
