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

During the initial touchdown the nose gear collapsed. Examination of the airplane by a Federal Aviation Administration inspector revealed that the nose gear oleo strut was broken, and the firewall was buckled. Examination of the oleo strut by the National Transportation Safety Board materials laboratory revealed that all of the fractures were on a slant plane, and were consistent with overstress fracture. The fractures occurred under bending overstress. There was no indication of any pre-existing fatigue cracking or corrosion.
