Taft

The emergency medical service (EMS/medevac) flight was dispatched to transport a patient in response to a medical emergency. During arrival to the destination, the pilot contacted the airport unicom for advisories and was advised to land on runway 25. Runway 25 had a 2.2 percent uphill grade and was restricted to landings only. After landing, the airplane was refueled and the patient was put on board. The pilot back-taxied on runway 25 and proceeded to take off uphill with the airplane near its maximum gross weight. According to ground witnesses, there was a tailwind, which they estimated was between 4 and 15 knots. The temperature was about 100 degrees, and the density altitude was about 3,200 feet. After the airplane became airborne, the pilot started an immediate left turn to avoid rising terrain. However, the left tip tank contacted the ground, and the airplane cartwheeled. It came to rest about 711 feet from the departure end of the runway. The flaps and landing gear were found fully extended; the published configuration for takeoff data in the flight manual was for 'wing flaps - up.' The airport had no signs to indicate runway use restrictions; however, the restrictions were published in the airport facility directory.

The aircraft was on a local flight involving a parachute jumping activity. In addition to the pilot, there were 12 parachutists and an observer on board. The pilot initiated his takeoff on runway 18. A witness stated that shortly after takeoff, the engine power was reduced to climb power, followed by the gear retraction. Reportedly, the aircraft had climbed to about 150 feet agl when the nose pitched up, the plane rolled to the left and then it crashed in a steep left bank, nose down attitude. An investigation revealed that the aircraft was loaded well beyond its maximum gross weight and aft cg limits. The amount of fuel on board was not verified, but even with no fuel, the plane would have been about 580 lbs over the maximum limit. With 100 gallons, the estimated gross weight would have been about 9,939 lbs with the cg at about 121 inches. The maximum certificated gross weight was 8,750 lbs with an aft cg limit of 117.6 inches. Extensive ground fire damage, but no preimpact, mechanical discrepancies evident.

En route from Ontario (California) to Moffett AFB, the crew decided to perform five consecutive stalls. Doing so, the airplane lost 3,000 feet and suffered severe vibrations that caused structural damages to skin, stringers and bulkheads in the aft portions of the fuselage. The pilot requested permission to divert to Taft Airport for an emergency landing but shortly later, the airplane disintegrated in the air and crashed in a mountainous area located 7 miles east of Taft. The aircraft was totally destroyed and all five crew members were killed.

The airplane crashed in unknown circumstances in a mountainous area located 15 miles west of Taft. At least one crew member was killed.
