The pilot approached high and fast for landing on runway 04. The wind was from 240° at 10 to 12 knots. The aircraft floated and after touchdown, the pilot was unable to stop on the wet, downsloping runway. After departing the runway, the aircraft continued down a steeper slope and into an area of brush and trees. All three gear collapsed, there was leading edge spar damage on both wings, and the right side fuselage skin, forward of the right wing, was damaged.

The aircraft crashed and burned shortly after taking off in darkness on an IFR flight plan. The weather was reported as indefinite ceiling, zero obscuration, visibility 1/4 mile with fog, wind 120° at 5 knots. A number of witnesses heard the aircraft, both before and after takeoff. The consensus of their statements indicated that one engine lost power while the other continued running at a high power setting. An investigation revealed that an intense post crash fire had consumed most of the aircraft. There was evidence that the plane had crashed in a steep nose down, right wing low attitude and did not move after impact. The right propeller was found in a feathered position. The left propeller blades were curled and twisted. Both engines were disassemble, but no evidence of a mechanical failure was found. The gear and flaps were retracted and the cowl flaps were closed. All three occupants were killed.

Pilot lost control of his aircraft during low altitude maneuvers to align the aircraft for landing. The low ceiling and rising terrain around the airport influenced the pilots decisions to make tight turns at low altitude. The aircraft was stalled and rolled inverted onto the runway during a turn.

A PA-31, N100FD, was being vectored by DFW approach control (approach control) for a landing on runway 13L at Dallas-Love Field. The pilot's last received and acknowledged instructions were to descend and maintain 2,000 feet and turn left to 190°. Simultaneously, a Cessna 337, N72430, departed runway 15 at Addison Airport, under tower control, and was to make a right climbing turn of approx 180°. Two min after takeoff, the pilot asked and got approval for freq change. 24 seconds later, he contacted approach control stating he had just departed Addison and was climbing to 2,500 feet on a 300° heading. The controller misunderstood the pilot's departure point and instructed him to change to frequency 120.5. The two aircraft immediately collided. A 2,000 feet ceiling was reported, two witnesses stated they could see more blue sky than clouds. A witness approximately 8 miles away saw a fireball in the clouds. Investigation revealed the controller, vectoring N100FD, prematurely cleared the aircraft to an altitude which was below the ceiling of the Addison Airport traffic area and prior to reaching the airspace delegated for that purpose by an ATC letter of agreement.

During departure, the pilot climbed in IFR conditions to 6,000 feet. After leveling, a frequency change was made and he was cleared to 8,000 feet, which he acknowledged. About 2 minutes later, the controller radioed to the pilot that he was about 4 miles north of the airway, but there was no reply from the pilot. Shortly after that radar contact was lost and the plane crashed in mountainous terrain. Several residents in the area reported hearing extremely loud engine noises followed by complete silence. An investigation revealed that both wings had separated outboard of their respective engine nacelle assemblies. An examination of the fractures revealed the wings had separated from positive overload. The leading edges of both wings had ballooned upward, indicative of extreme airspeed. The empennage had separated in a yaw and from right torsional overload. Parts of the aircraft were found within a 1 mile arc, north of the main impact area. The pilot's recent instrument experience could not be verified. All three occupants were killed. Turbulence was forecasted below 8,000 feet.

Following a missed approach to Aurora-Sugar Grove Airport, the twin engine airplane descended in a left turn, causing the left wing to struck the ground first. The aircraft broke up and caught fire. The pilot, sole on board, was killed. No malfunctions found.

A maintenance supervisor and two pilots noted that the left engine did not respond normally while being started. Aft starting, the pilot taxied to runway 10 for an IFR departure. Since the taxiway did not extend to the end of the runway, the pilot of another aircraft waited on the taxiway, just short of the runway, approximately 2,967 feet from the end. He observed smoke coming from the left engine of the MU-2 and reported this info on the unicom frequency. He reported that the MU-2 continued and rotated for takeoff approximately 200 to 250 yards east of his position. Reportedly, the aircraft climbed to approximately 300-400 feet afl, then turned left toward higher terrain. After turning, it enter what two witnesses described as a VMC roll, then crashed and burned. An examination of the airframe revealed no preimpact mechanical failures. A teardown of the left engine revealed that a turbine bearing, pn 3101092-1, had been misaligned and subsequently began to fail, damaging the 2nd and 3rd stages of the turbine section. The airport elev was 6,597 feet. The computed takeoff roll was 1,620 feet and the computed accelerate stop distance was 3,100 feet. The landing gear and selector found in down position. The aircraft was destroyed and all six occupants were killed.

The approach to Rio Branco-Presidente Médici Airport was initiated in poor weather conditions. On final approach in rain falls, the crew was unable to locate the unlighted runway and decided to initiate a go-around. A second approach was abandoned few minutes later for the same reasons. During a third attempt to land, the airplane stalled and crashed 5 km from the airport. It was destroyed on impact and all 10 occupants were killed.

Crashed in unknown circumstances while approaching Pretoria-Wonderboom Airport. The occupant fate is unknown. It is believed that the aircraft went out of control following a fire in the cabin while on approach.

During the takeoff roll on runway 01 (805 meters long grassy runway), the twin engine aircraft encountered serious difficulties to gain the necessary speed of 85 knots. It overran, rolled through a cornfield, crossed a motorway and came to rest against a dirt bank, bursting into flames. All four occupants were injured, the pilot seriously. The aircraft was totally destroyed by a post crash fire.
