Probable cause

The pilot’s failure to maintain an adequate glidepath during approach, which resulted in an impact with a semi-truck.

Findings · 3

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 approach in visual meteorological conditions, he referenced the RNAV instrument approach for the runway to assist with vertical guidance "as [there] is no VASI [visual approach slope indicator]" for that runway. He added that he thought he was high enough as he crossed the adjacent highway, but the airplane hit a semi-truck that was traveling across the airplane's flightpath. The airplane continued on short approach, landed, and the main landing gear collapsed. Subsequently, the airplane veered to the left off the runway. The airplane sustained substantial damage to the left and right engine firewalls and nacelle tanks. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
