Findings · 2
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 accident occurred during the student pilot's third landing on his first solo flight. He reported that he flew the final approach between 72 and 74 knots and that he reduced engine power as the airplane crossed-over the runway numbers. He stated that the stall warning horn sounded as he flared, but the aircraft did not descend onto the runway. He reduced his yoke back pressure and the airplane landed hard on the runway. The airplane then proceeded to bounce several times before stabilizing on a landing rollout. An after-flight inspection revealed that one of the propeller blade tips was curled from contact with the runway and that the engine firewall was substantially deformed.
