Probable cause
The certificated flight instructor's failure to follow correct engine clearing procedures. A factor was the unsuitable landing area.
Findings · 4
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The certificated flight instructor (CFI) and student pilot departed on an introductory instructional flight towards a training area where they performed basic flight maneuvers. They then flew to an airport where the CFI demonstrated a simulated forced landing which was to be followed by a go-around to a runway that was reportedly covered with about 12-14 inches of snow. During the demonstration, the CFI reduced engine power to idle from an altitude of 2,000 feet mean sea level and executed a descent to an altitude of about 5 - 6 feet above ground level at 60 knots indicated airspeed. The CFI did not increase engine throttle during this descent to clear the engine. The CFI applied full throttle during the go-around, but the engine hesitated and the airplane continued to descend. The main landing gear wheels followed by the airplane's nose contacted the snow. The left wing contacted the ground followed by the right wing.. Both wings buckled, resulting in substantial damage to the airplane. The Federal Aviation Administration Flight Training Handbook states in the section under 'Descents (Maximum Distance Glides)' that during power-off descents, the engine should be cleared periodically to prevent excessive cooling and fouling.
Factual narrative
A flight instructor and student pilot departed on an introductory instructional flight towards a training area where they performed basic flight maneuvers. They then flew to Flying U Ranch Airport, Union Mills, Indiana, where the flight instructor demonstrated a simulated forced landing which was to be followed by a go-around to runway 18 (2,745 feet by 100 feet, grass). The runway was reportedly covered with about 12-14 inches of snow. During the demonstration, the flight instructor reduced engine power to idle from an altitude of 2,000 feet mean sea level and executed a descent to an altitude of about 5 - 6 feet above ground level at 60 knots indicated airspeed. The flight instructor did not increase engine throttle during this descent to "clear the engine." The flight instructor applied full throttle during the go-around, but the engine hesitated and the airplane continued to descend. The main landing gear wheels followed by the airplane nose contacted the snow. The left wing followed by the right wing then contacted the ground. Both wings buckled from the ground contact resulting in substantial damage to the airplane. The flight instructor accumulated a total flight time of 2,163 hours as an instructor.
