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 reported that, during the landing flare, he was startled by the airplane impacting the runway early and then bouncing. Subsequently, the airplane touched down hard and porpoised. He increased power to abort the landing and retracted the flaps, but the airplane was unable to take off. He reduced engine power, and the airplane rolled to a stop on the runway. The airplane sustained substantial damage to the lower fuselage bulkhead. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Factual narrative
The pilot reported that during the landing flare, he was startled by the early impact and bounce. The airplane touched down hard and bounced about three times in a "porpoise pattern." He increased power to abort the landing, and he retracted the flaps but, "It was too late to recover." He reduced engine power and the airplane rolled to a stop on the runway. The airplane sustained substantial damage to the lower fuselage bulkhead. The airport's METAR reported that about the time of the accident, the wind was from 210° at 5 knots. The airplane landed on runway 04L. The airport elevation was 618ft, the temperature was 82°F, the barometric setting was 29.94, and the estimated density altitude was 2,300ft. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
