Circumstances:

The crew was completing a local training flight at Khartoum-Haj Yusuf Airport. Following several circuits and landings, the crew started a new approach to runway 36 with engine at idle. The airplane stalled, struck the roofs of two houses then crashed onto the ground, hit a truck and came to rest, broken in two. Two crew members were killed while two others were injured.

Probable cause:

Due to the lack of conclusive evidence it is not possible to formulate an opinion as to the direct cause of the accident. From the evidence available it is possible that one or more of the following items could have contributed tot the cause of the accident:
- No satisfactory reason has yet been put forward for the initial turn of the aircraft to the port,
- The loss of height after the turn was probably caused by the selection of the flaps from 1/4 position to the 'UP' position,
- From witness' statement it would appear that at some time after the aircraft was starting to re-commence climbing on one or both of the engines 'coughed'. This could have been caused by the inadvertent mishandling of either the throttle and/or mixture control levers by the pilot under training as he left his seat. The possibility also exists that he may have pulled himself up by the ignition master switch, at the same time inadvertently switching 'off' the port ignition switch. (evidence of an explosion in the port exhaust system could have been caused by either of the above events,
- If anything like the possibility mentioned in item 3) did in fact occur it would have been just at the critical time when the Training captain was re-gaining control of the aircraft, and could have presented him with a situation from which it was impossible to recover, bearing in mind the proximity of obstructions and the fact that he was alone in the cockpit.

Circumstances:

En route from Cairo to Khartoum at an altitude of 20,500 feet, a loss of hydraulic pressure occurred. The crew continued the flight and started the descent to Khartoum. While completing the approach checklist, the crew was unable to lower the landing gear, even with the emergency systems. The captain decided to complete a belly landing on the sandy area alongside the runway. The airplane slid for hundreds yards before coming to rest. All 27 occupants were evacuated safely while the aircraft was damaged beyond repair.

Probable cause:

It was determined that the failure of the support member for the starboard main gear uplock caused the gear to fall in flight, damaging hydraulic system lines.

Circumstances:

The aircraft was on its way from Khartoum to London with an intermediate stop at Cairo, carrying a crew of five and 25 passengers on behalf of the 36th Squadron. After takeoff from Khartoum Airport, while climbing, the pilot informed ground that the engine number two failed and received the permission to return for a safe landing. The captain made a turn to the left to join the approach path when the airplane rolled left and right and eventually banked left. In such conditions, the captain decided to shut down the engine number one he thought that was malfunctioning. While trying to maintain a stable attitude, he lost control of the airplane that stalled and crashed. On impact, the undercarriage and all four engines were sheared off and the aircraft skidded for several yards before coming to rest. While all 25 passengers were injured, all five crew members were killed.

Probable cause:

Investigations were unable to determine the exact cause of the failure of the engine number two. Technical analysis on engine number one did not reveal any issues so the decision of the pilot to shut it down was unfounded.

Circumstances:

The aircraft left Khartoum International Aerodrome at 0555 hours GMT on 10 July carrying a crew of 6 and 14 passengers and was cleared to cruise at 17 500 feet. At 0610 hours, at about 10 500 feet altitude, the number two engine fire warning light for zones 2 and 3 came on and the warning bell rang. The engine was feathered. The CO2 bottle was released and concurrently an explosion followed by a violent fire, made it necessary (at approximately 0620) to land the aircraft with gear up on a large flat cultivated area. There were no injuries to passengers or crew, but the aircraft was almost totally destroyed by fire which continued burning on the ground.

Probable cause:

This accident was due to the overheating of one of the brakes of the main landing gear during the aircraft's taxiing and take-off run. It was caused by a dragging brake and a leakage of hydraulic oil with resultant fire and tire blow out. The tire blow out resulted in damage to hydraulic oil and fuel lines within the confined area of No. 2 engine nacelle, between the rear of the engine fire wall and rear spar, and between the fuselage and left side of the landing gear wheel well doors.
