Total fatalities:

Circumstances:
The aircraft was engaged in a special flight on behalf of the International Committee of the Red Cross (ICRC), carrying 20 passengers and two crew members. During the takeoff roll, the crew encountered directional problems and the aircraft deviated to the right of the runway. The crew was able to takeoff when shortly after liftoff, the right wing struck a mast. The airplane nosed down, struck the ground, lost its nose gear and came to rest in a potatoes field. All 22 occupants were evacuated, among them four passengers suffered minor injuries. One people on the ground was killed.
Probable cause:
It is believed the crew encountered problems with the ailerons and the nosewheel steering system due to hydraulic issues.

The aircraft entered a dive and crashed on the village of Cancao located about 40 km west of Kuito. The aircraft disintegrated on impact and at least eight houses were destroyed. All six occupants were killed as well as two other people on the ground.

Aircraft flight hours:

Circumstances:
The single engine aircraft departed Grenchen Airport on a local skydiving flight, carrying eight skydivers and one pilot. At the altitude of 1,000 meters, the instructor opened the door and the pilot stabilized the airplane and reduced the speed. The first skydiver bailed out and when the second skydiver was ready, the instructor realized his dorsal parachute bag was partially open and decided to push him outside the cabin. Immediately after, he heard a shock and saw that the horizontal stabilizer was damaged. It is believed that the first skydiver probably made an excessive traction on the strap which may cause the automatic open of the next skydiver. In such situation, all other skydivers and the instructor bailed out. The pilot attempted several times to stabilize the airplane but unable to reach Grenchen Aerodrome, he bailed out at a height of 300 meters. Out of control, the airplane crashed in an open field and was destroyed. All nine occupants were uninjured.
Probable cause:
The accident was the consequence of the following findings:
- Poor layout of the automatic opening system of the straps in the cabin,
- An horizontal stabilizer was damaged by parachute elements.
- Poor layout of the automatic opening system of the straps in the cabin,
- An horizontal stabilizer was damaged by parachute elements.

Captain / Total hours on type:

Aircraft flight hours:

Circumstances:
The pilot, sole on board, was completing a cargo flight from Riyan to Aden with an intermediate stop in Al Furt. On approach to runway 35, he observed big birds standing near the runway threshold and opted for a downwind right hand short base landing. On short final, the single engine airplane stalled and crashed. The aircraft was destroyed and the pilot was seriously injured.
Probable cause:
The accident was the consequence of the following:
- Inappropriate flight technique,
- The last turn was completed below lift speed,
- Turbulences and windshear may have been contributing factors.

Circumstances:
One minute after takeoff from the Q5 A-103 Oil Field, en route to Benghazi, the single engine airplane went out of control and crashed. The airplane was totally destroyed and both pilots were killed. The accident occurred about 350 km southeast of Benghazi.
Probable cause:
It was determined that the loss of control during initial climb was the consequence of a poor flight preparation on part of the crew who failed to follow the pre-takeoff checklist and failed to remove the system that was blocking the aileron on the left wing.
