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 the airplane approached the runway with a "steep angle [and] high descent rate." He added that the airplane "touched the ground before flaring" and that the airplane porpoised on the runway. Subsequently, the nosewheel tire popped, and the strut partially collapsed. The pilot reported that he stopped the airplane on the runway and radioed for assistance. The firewall and fuselage sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
