Confidence Rating: Accident investigation report completed and information captured
The airplane was approaching Grain Valley after a flight from Tuscaloose (TCL). Approximately 3 miles from the airport, and 3,000 feet mean sea level on a left
base for runway 27, N620PA was cleared for a visual approach to runway 27. The landing gear was in the extended position and the before landing checklist was completed to flaps half. The pilot entered final, intercepted the visual approach slope indicator, and selected full flaps about 2 miles from the airport. The
airplane was reported to be at a constant airspeed and descent rate. The before landing checklist was completed. Approximately 150 feet from the runway
threshold, a sink rate developed, full power was applied, and the landing gear impacted approximately 5 feet from the runway threshold. The power was
increased on the right engine to maintain directional control. The left landing gear folded backwards during the last 10 feet of the landing. The airplane came to
rest to the right of the runway in the grass and the flight crew evacuated through the over-wing emergency exit.
The captain stated to the NTSB that he was "tired' and did not sleep since he began company flying on the day before the accident at 20:30. He stated that he and the first officer spent several hours on the ground in Alabama where they got lunch but did not sleep.

PROBABLE CAUSE: "The pilot not maintaining clearance from the fence. Contributing factors were the pilot's fatigue and the fence."
