Probable cause

The canopy opening shortly after takeoff due to an inadequate repair and subsequent failure of the canopy latch, resulting in a emergency landing. Contributing to the accident was the lack of available runway remaining for the forced landing.

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 cockpit canopy latch broke at the conclusion of the previous flight. The latch was welded and reinstalled prior to the accident flight. After takeoff, the repaired canopy latch failed as the airplane climbed through 50 feet above ground level (agl). The pilot attempted to land on the remaining runway due to the possibility of the canopy separating and striking the empennage in flight. However, after landing, he was unable to stop on the remaining runway and the airplane struck a ditch during the runway overrun. The nose landing gear subsequently collapsed and the airplane nosed over.
