Demonstration

The pilot was executing a high speed pass over the runway at about 250 feet agl. The pilot then began a rapid pull-up and both wings separated just outboard of the engine nacelles. Reconstruction of the sequence from a videotape revealed that the aircraft's speed at the time of the wing separations was 220 knots. Vne for the aircraft is 193 knots. It was calculated that, at 220 knots and an 8° nose-up pitch, the 'g' load at the time of the wing separations would have been 8.3 g's. The pilot, sole on board, was killed.

The pilot, sole on board, was taking part to an airshow at RAF Culdrose, Cornwall. While completing a 360 turn at low height, one of the wing struck the ground and the airplane crashed. The pilot was killed.

The pilot and a prospective buyer/passenger were on a local demonstration flight. Prior to this flight, the aircraft had been parked for nearly one year. Since the last annual inspection on 12 January 1982, it had been flown only 66 hours. During the preflight, the pilot found the fuel tanks between 1/4 full and empty. The sumps were drained, the main tanks were filled, then the sumps were drained again. After takeoff, the pilot leveled the aircraft at 1,500 feet in a cruise configuration. Shortly thereafter, the left engine began running rough, backfiring and losing power. The pilot turned back toward the airport, but the engine lost all power and the propeller was feathered. While returning, the right engine's cylinder head and oil temperature began rising above the red line. Subsequently, it began losing power and a wheels-up, forced landing was made in an open field. An examination revealed that both engines were out of time, firing was intermittent and distributor block on the left engine was burned due to incorrect timing. Also, the left turbocharger gate was stuck open and the left fuel filter was partially clogged. Both occupants escaped uninjured.

The twin engine airplane departed Honolulu Airport to take part to a local airshow, carrying 11 skydivers and one pilot. While making a turn toward the jump area, the airplane entered a spin. Four occupants parachuted before the airplane crashed in Pearl Harbour. Only one passenger survived the crash and was seriously injured while 11 other occupants were killed. The airplane was destroyed.

The crew was engaged in a local demonstration flight to potential customers. After takeoff, while flying at a speed of 155 knots and an altitude of 690 feet, the crew initiated a barrel roll when control was lost. The airplane dove into the ground and crashed near the airbase, killing both pilots.

The pilot, sole on board, departed Fayetteville, NC, on a flight to Wilmington to demonstrate the airplane to potential customers. After being cleared for a VOR approach to runway 34, the pilot started the descent in bad weather conditions with thunderstorm activity. In severe turbulences, control was lost and the airplane stalled and crashed in a field. The aircraft was destroyed and the pilot was killed.

This aircraft was delivered on 17 October to TAB1 at Wagner Field, a disused auxiliary airfield at Eglin Air Force Base, Florida. Between 19 October and 28 October, numerous flights were made testing various aspects, including the double-slotted flaps system, which enabled the C-130 to fly at 85 knots on final approach at a very steep eight-degree glide slope. All aspects worked flawlessly, and a full profile test was scheduled for 29 October. The test's takeoff phase was executed flawlessly, setting a number of short takeoff records. The Lockheed test crew then assessed that the computer used to command the firing of the rockets during the landing sequence needed further calibration, and elected to manually input commands. The reverse-mounted (forward-facing) eight ASROC rockets for decelerating the aircraft's forward speed were situated in pairs on the fuselage's upper curvature behind the cockpit, and at the midpoint of each side of the fuselage beneath the uppers. Testing had determined that the upper pairs, fired sequentially, could be ignited while still airborne (specifically, at 20 feet), but that the lower pairs could only be fired after the aircraft was on the ground, with the descent-braking rockets also firing during the sequence. The flight engineer, blinded by the firing of the upper deceleration rockets, thought the aircraft was on the runway and fired the lower set early. The descent-braking rockets did not fire at all. Later unofficial disclaimers allegedly made by some of the Lockheed test crew's members asserted that the lower rockets fired themselves through an undetermined computer or electrical malfunction, which at the same time failed to fire the descent-braking rockets. As a result, the aircraft's forward flight was immediately reduced to nearly zero, dropping it hard to the runway and breaking the starboard wing between the third and fourth engines. During rollout, the trailing wing ignited a fire, but a medical evacuation helicopter dispersed the flame and crash response teams extinguished the fire within eight seconds of the aircraft stopping, enabling the crew to exit the aircraft safely. 74-1683 was dismantled and buried on-site for security reasons, but most of its unique systems were salvaged.

The aircraft was taking part to an airshow at Biggin Hill Airport for the Battle of Britain air display. Shortly after take off from runway 21, the pilot made a turn to pass over the airport when the aircraft nosed down and crashed in a huge ball of fire about 500 yards from the airfield. All seven occupants were killed.

The twin engine airplane was engaged in a demonstration flight from Mobile to Ocala, Florida, carrying five passengers and one pilot. After takeoff, the airplane encountered serious difficulties to gain height, stalled and crashed. All six occupants were killed.

The airplane was taking part in Samoa's Flag Day celebration. It was dropping skydivers near the reviewing area. During the second run, the airplane clipped a mile-long tramway line running across Pago Pago Harbor to Mount Alava. Part of the wing separated and the airplane crashed in flames into an area in front of the two-storey Rainmaker Hotel. All six occupants as well as two people on the ground were killed.
