Circumstances:
After his departure from Miles City Airport, while climbing by night over an unlighted area, the pilot was cleared to climb to 6,000 feet. At a relative low altitude and high speed, the left wing outboard section failed and detached. Out of control, the airplane dove into the ground and crashed in a field. The pilot, sole on board, was killed.
Probable cause:
Airframe failure in flight and uncontrolled descent after the pilot diverted attention from operation of aircraft. The following contributing factors were reported:
- Exceeded designed stress limits of aircraft,
- Airframe - wings: other,
- Separation in flight,
- Overload failure,
- Fire after impact.
