Probable cause
The pilot’s failure to extend the landing gear before landing.
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 pilot stated that, when he returned to the airport after a local flight, two airplanes were in the traffic pattern and a third airplane was inbound about 10 miles east. To sequence with the two airplanes in the pattern and the third airplane on the extended downwind leg, the pilot did not enter the traffic pattern at the midpoint of the downwind leg, but entered the traffic pattern closer to the approach end of the intended runway. He lowered the flaps, but did not lower the landing gear. He turned onto the base leg, extended full flaps, and then turned onto final approach. While on final approach, the pilot had a sense that the airplane was fast and that the “sight picture” was lower than usual, but he did not detect that the landing gear was retracted or recall hearing the landing gear warning horn. He heard the propeller contact the runway and attempted to lower the landing gear, but it was too late. He heard the landing gear warning horn after the airplane came to rest. Postaccident examination of the airplane revealed that a main stringer and leading edge rib inside the right wing were damaged. The pilot stated that there were no preimpact malfunctions or failures that would have precluded normal operation.
Factual narrative
The pilot stated that after departure he proceeded to the local practice area then elected to return. Two airplanes were in the traffic pattern and a third airplane was about 10 miles to the east inbound. In order to sequence with the 2 airplanes in the pattern and the third airplane on the extended downwind, he entered the traffic pattern close to the approach end of the intended runway rather than midfield downwind. He lowered the flaps, but “…failed to lower the gear at the ‘key’ point….” He turned onto base where he extended full flaps then turned onto final approach. While on final approach he had a sense that the airplane was fast, but did not detect that the landing gear was retracted. He continued the approach and sensed that the sight picture was lower than usual, but did not recall hearing the landing gear warning horn. He heard the propeller contact the runway and attempted to lower the landing gear but it was too late. He heard the landing gear warning horn after the airplane came to rest. Postaccident inspection of the airplane revealed a main stringer and leading edge rib inside the right wing were damaged.
