Circumstances:
The four engine aircraft with dual registration F-RAFB and 43748 was engaged in a flight from Saint-Denis de la Réunion to Paris with an intermediate stop at Djibouti City, on behalf of the Groupe de Liaisons Aériennes Ministérielles (GLAM). It arrived at Saint-Denis Airport in the morning and was supposed to stay an overnight in Saint-Denis. Thus, the crew was released for the day but finally called for a departure in the evening. 55 seconds after takeoff from runway 13 in light rain, the pilot was contacted by the controller at the airport who told him he was turning to the wrong direction and asked him to make an immediate turn to the left while gaining altitude. The pilot acknowledged the message when the left wing struck two araucarias and crashed in flames in a wooded area located about 5 km southeast of the airfield. The aircraft was destroyed by impact forces and a post crash fire and only one passenger survived while 19 other occupants were killed, among them General Charles Ailleret, Chief of Staff of the French Army. He was returning to Paris following an inspection of the French troops stationed in the Indian Ocean. The only survivor was Mrs Michèle Renard, personal nurse of General Ailleret.

Probable cause:
The exact cause of the accident was not determined with certainty. However, it is believed that the crew suffered an extreme fatigue at the time of the accident due to insufficient rest time (sleep time). For unknown reason, the crew started a turn to the right after takeoff from runway 13 which is not compliant with the published departure procedures for Saint-Denis-Gillot Airport.

Circumstances:
The flight NB821, a non-scheduled air transport operation from Stockholm-Arlanda Airport to Gothenburg-Torslanda Airport, took off from Arlanda on 23 December 1967 at 0637 hours GMT. The aircraft was flown in accordance with an approved flight plan. The first approach was discontinued at critical height due to insufficient visual references. During the second approach the pilot-in-command took over the aircraft at a low altitude and landed. A heavy touchdown was made on runway 22 approximately 3,000 feet after the threshold at 0801 hours GMT. The aircraft sustained substantial damage and all 55 occupants were evacuated safely.
Probable cause:
The Board determines the cause of the accident was non-regulative use of reverse before firm ground contact. The following contributing factors were reported:
- The pilot-in-command took over the controls and continued the approach just after the co-pilot had started to level off at minimum altitude,
- The approach was high,
- The touchdown was made 3 000 ft after the threshold,
- The pilot-in-command applied reverse power before ground contact,
- The pilot-in-command's action was most probably affected by the high approach and the short runway.

Circumstances:
While cruising at an altitude of 15,500 feet over Holmdel, New Jersey, the aircraft suffered an explosive decompression of the cabin. A 60 by 125 inches 'panel' detached from the fuselage and struck the engine number three, causing the detachment of its propeller. The crew started an emergency descent and was able to complete an emergency landing at New York Airport. All 14 occupants were evacuated safely while the aircraft was later declared as damaged beyond repair.
Probable cause:
Fatigue fracture of the fuselage and explosive decompression caused by an inadequate maintenance and inspection on part of the ground maintenance personnel. Investigations reported that at the time of the decompression, the cabin was pressurized for 2,500 feet while the aircraft was flying at an altitude of 15,500 feet.

Circumstances:
Flight 203 was a scheduled domestic flight from La Mesa Airport, Cortis Department, to Toncontín, Tegucigalpa, D.C., with three flight crew members, two stewardesses and fifty passengers on board. The gross weight of the aircraft at take-off was 75 023 lbs. After a routine pre-flight check which did not reveal any abnormality, the aircraft took off from La Mesa at 0815 hours. Its estimated flight time was 32 minutes and the en-route altitude was 7 500 ft. After 23 minutes of flight the aircraft contacted Toncontín control tower over "El Rancho" and requested authorization to use frequency 118.1 Mc/s. This was acknowledged by the tower which cleared the aircraft to enter the circuit for a landing on runway 01, the wind being calm. The crew then requested to use runway 19 but the tower refused because there was some traffic on runway 01 and several aircraft were waiting to land on that runway. The landing was initiated, 20° of flaps and the undercarriage were lowered; the pilot reported on base leg and extended the flaps to 300. According to the flight crew the indicated airspeed was 100 kt over the fence located before the threshold of runway 01. The landing was normal and smooth and immediately after the nose-wheel touched down the pilot-in-command called for withdrawal of the safety lock of the propeller reverse system. This was done; however the throttle controls would not shift to the desired position (rearward) to operate the propeller reverse system satisfactorily. Three consecutive attempts were made without success. The pilot evaluated the situation and, since the air- craft had passed the point where a go-around could be attempted, he decided to use the brakes only as they appeared to operate normally at the time. According to some reliable observers (aviation mechanics and tower controllers) one of the aircraft's tires burst approximately halfway down the runway and another tire, possibly on the opposite side, burst 50 m farther down. It was assumed that these tires were the two outermost tires. As the aircraft was nearing the end of the runway, the pilot-in-command became afraid of the pronounced slope ahead and veered to the left to execute a 180° turn (ground loop). The turn was successfully completed; however, due to the aircraft's inertia, the radius of the turn was too wide and the nose-wheel ran into a drainage ditch; the aircraft then skidded, the left undercarriage ran into the same ditch and stayed in it, the nose-wheel broke off, the left wing fuel tanks burst and the propellers of Nos. 1 and 4 engines were damaged. A fire resulting from the intense heat of the brakes and wheels, the spilled fuel and the dry grass immediately broke out and destroyed the aircraft. Four passengers were killed while 51 other occupants were evacuated. The aircraft was destroyed.
Probable cause:
According to the reports of the crew, the probable cause of the accident was the failure of the reverse pitch control mechanism. The Board was not able to confirm or deny this because the fire had obliterated all traces of any possible cause.

Circumstances:
The crew was completing a cargo flight to Kelly AFB, San Antonio, Texas, on a subcontract for the US Air Force. While descending to Kelly AFB, the crew decided to divert to San Antonio-Intl Airport for unknown reason. While on a night approach, the pilot-in-command failed to realize his altitude was too low when the airplane struck trees, stalled and crashed in a cleef. The aircraft was destroyed and all three crew members were killed. At the time of the accident, the airplane was 1,100 feet below the glide.
Probable cause:
The cause of the accident was not determined.
