Circumstances:
Shortly after takeoff from Alexandria Airport, the crew informed ATC about the explosion of the left engine and requested the permission to divert to Cairo-Intl Airport for an emergency landing. Due to severe damages caused by the explosion, the crew was unable to lower the gear nor the flaps. Eventually, the captain decided to belly landed in a sandy area located near the runway 05. The airplane slid for dozen yards, came to rest and was damaged beyond repair while all 15 occupants escaped uninjured.
Probable cause:
Explosion of the left engine due to the presence of a foreign object in the rear cone of the left engine nacelle.

Circumstances:
The approach to Addis Ababa-Haile Selassie I Airport was completed by night and marginal weather conditions. On final, at an altitude of 150 feet, the pilot-in-command made a visual contact with runway 32 but the aircraft was 250 feet to the right of the extended centerline. The captain decided to make a turn to the left when the aircraft banked left, lost height and struck the ground. Out of control, it crashed by the runway and came to rest. All 14 occupants were injured and the aircraft was destroyed.
Probable cause:
Wrong approach configuration on part of the flying crew who continued the approach below minima weather conditions and passed the minimum descent altitude without any visual contact with the ground or runway. In such conditions, the captain should make a go-around procedure.

Circumstances:
The crew was performing a cargo flight from Faro to Uli with an intermediate stop in São Tomé with ammunition on board. While overflying Morocco by night, the crew encountered engine problems and informed ATC they want to divert to the nearest airport. The aircraft lost altitude then struck the slope of Mt Tibhirine located near the Mt Toubkal, south of Oukaïmeden, in the Atlas range. All SAR operations were suspended after few days as no trace of the aircraft nor the crew was found. In July 1970, the debris were located on the top of the mountain, at an altitude of 3,900 meters. All eight occupants were killed and the aircraft was totally destroyed by impact forces.
Probable cause:
According to the the Biafran government, three of the four engines were out of service at the time of the accident.

Circumstances:
Following an uneventful flight from Kano, the crew started the descent to Lagos-Ikeja Airport. The captain was cleared for a straight-in approach but encountered low visibility due to foggy conditions. On final, the crew failed to realize his altitude was insufficient when the airplane struck trees and crashed 13 km short of runway 19. The aircraft was totally destroyed and all 87 occupants have been killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. The FDR was found undamaged but the British AAIB engineers reported it was unreadable as the data consisted only of a stream of alternating ones and zeros. Apparently there had been a fault in one of the logic units of the system, something which could not be detected from the flight deck. No readable data could be reconstructed from this. Nevertheless, it is believed that the flying crew led the aircraft descending below the minimum safe altitude while still under control.
