What happened
A flight instructor was conducting multiengine training for a private pilot rated in single-engine aircraft. The training was being performed in a late 1930s vintage amphibious airplane. During the flight, which was intended to teach engine-out procedures, the instructor intentionally reduced power to the right engine to simulate a mechanical failure. This maneuver occurred at approximately 600 feet above ground level as the pilot was initiating a left turn and retracting the landing gear.
Following the simulated failure, the pilot performed the required emergency procedures. While the instructor was scanning the surrounding area for other aircraft in the pattern, the pilot reported that the aircraft was losing altitude despite reaching the recommended airspeed. The instructor subsequently moved the right throttle to a half-power position. During the descent, the aircraft struck the ground and subsequently caught fire. The accident resulted in fatalities.
Findings
- The aircraft lacked published performance data, meaning the instructor relied on experience from previous flights to manage the aircraft's capabilities.
- The intentional reduction of power to simulate an engine failure occurred during a critical phase of flight involving gear retraction and maneuvering.
- There was uncertainty regarding whether the pilot had properly adjusted power controls following the initial takeoff power application.
