Findings · 1

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

On the base leg of the traffic pattern, the pilot lowered the landing gear and the green landing gear indicator light illuminated. During the subsequent landing, the main gear touched down, and “the nose came down like normal but kept going down with a sudden bang.” The airplane slid off the runway, came to rest in the grass, and sustained substantial damage to the forward lower fuselage. Examination of the airplane revealed that forward end of the landing gear actuator rod was fractured. The failure resulted in insufficient tension to keep the over-center down lock assembly in place.
