While attempting to depart from the 3,500-foot long grass airstrip with a 14 knot quartering tailwind, the 5,800-hour pilot reported that at an airspeed of approximately 95 knots, "the airplane yawed left and rolled left abruptly as the aircraft came off the ground briefly." The airplane settled back onto the ground, before again climbing back into the air approximately 20 degrees left of the runway heading. Subsequently, the airplane’s landing gear struck tree tops before it impacted the ground. A passenger added that he "noticed the flaps were up during takeoff." Approximately three minutes after the accident, a weather reporting station located 5.6 nautical miles southwest of the accident site reported wind from 010 degrees at 14 knots. Examination of the engines revealed rotational scoring throughout the first and second stage turbines. No mechanical anomalies were observed.

On approach to Tampico-General Francisco Javier Mina Airport, the crew established on the ILS. The aircraft descended below the glide and MDA until it struck the ground and crashed in a lagoon located 12,8 km short of runway. A pilot and two passengers were killed while five other occupants were injured. The aircraft was destroyed.

After approximately 1.5 hours of pipeline patrol flight at a planned altitude of 500 feet agl the aircraft flew into the flat terrain in a landing attitude. The aircraft went through a wire fence, heavy brush and small trees before coming to rest 437 feet from initial ground contact with all 3 gear collapsed. A physical examination and the pilot's statement indicate that the pilot was operating under an extreme amount of stress which may have resulted in chronic fatigue at the time of the accident. According to the pilot, he was accustomed to a very heavy flight schedule. The chief pilot attempted to assign an additional pilot but company budget constraints prevented such an assignment.

While in cruising altitude in marginal weather conditions on a flight from Houston to Dallas, the pilot lost control of the airplane that entered a dive. During the descent, wings and stabs separated and the aircraft crashed near Madisonville. All three occupants were killed.

En route from Houston to Mineral Wells, the pilot encountered poor weather conditions with thunderstorm activity and turbulences. While flying in adverse weather conditions, he suffered a spatial disorientation and lost control of the airplane that dove into the ground and crashed in a field near Hammond, bursting into flames. All three occupants were killed.

After takeoff from Lajitas Airfield, the twin engine airplane encountered difficulties to gain height. It struck power cables then crashed, bursting into flames. The pilot and one passenger were killed while eight other occupants were injured, five of them seriously.

After takeoff from Palacios Airport, while climbing, both engines lost power. The pilot was cleared to return for an emergency landing and initiated a turn. While flying at low height, the twin engine airplane struck power cables and crashed in a field. All four occupants were slightly injured.

While cruising at an altitude of 41,200 feet, the airplane entered an uncontrolled descent following an airframe failure in flight. The airplane crashed in an open field and was totally destroyed. Both pilots who were completing a ferry flight from Vernal to Houston were killed.

The airplane landed in rain falls with a 18 knots tailwind about 2,000 feet down runway 13 which is 5,800 feet long. Unable to stop within the remaining distance, the airplane overran and came to rest in a ditch about 350 feet further and 200 feet to the right of the extended centreline. All 50 occupants escaped without injuries while the aircraft was damaged beyond repair. At the time of the accident, the total weight of the airplane was 71,000 lbs.

While in cruising altitude on a night flight from Houston to Tampa, the pilot encountered poor weather conditions with icing. After the pilot suffered a spatial disorientation, the twin engine airplane entered an uncontrolled descent and partially disintegrated in the air before crashing in a lake located near Leeville. Both occupants were killed.
