Circumstances:
While descending to Bamako-Senou Airport, the crew was informed about the poor weather conditions at destination with thunderstorm activity and strong crosswinds. As the visibility was estimated to be above 10 km, the crew decided to continue the approach. After landing on runway 06, the aircraft was caught by strong crosswinds and started to roll left and right, causing the right wing to struck the runway surface. Out of control, the aircraft veered off runway to the right and collided with a bunker. The right wing was torn off and the aircraft came to rest. All four crew members escaped uninjured.
Probable cause:
Loss of control after landing due to strong crosswinds in thunderstorm activity.

Circumstances:
Twenty-three minutes after takeoff from Tynda Airport, while cruising at an altitude of 5,700 metres, the crew encountered technical problems with the engine n°2 (central engine). Due to an excessive temperature of the turbine, the captain decided to shut this engine down (the engine n°2 is equipped with a thrust reverser system). While descending to Aldan Airport, the aircraft approached in a nose down attitude and struck the ground 90 metres short of runway threshold with a positive acceleration of 4 g. On impact, the nose gear collapsed, the aircraft bounced several times then slid for 800 metres before coming to rest on the runway. All 11 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
The following findings were reported:
- The crew took the wrong decision to fly to Aldan Airport instead of the alternate,
- The approach was continued with excessive gap related to the approach speed and altitude,
- On final, the aircraft was in an excessive nose down attitude,
- The crew failed to identify and correct the wrong approach configuration.

Circumstances:
On approach to Cafunfo Airport, following an uneventful cargo flight from Luanda, the crew encountered bad weather conditions with thunderstorm. On short final, the pilot reported a minor technical problem with the left engine and initiated a go-around procedure. Shortly later, the aircraft stalled and crashed short of runway, bursting into flames. Four crew members were killed and four others were injured.
Probable cause:
Loss of control while initiating a go-around procedure due to a stall consecutive to an insufficient speed.

Circumstances:
Following an uneventful flight from Dalian, the crew started the descent to Shanghai-Hongqiao Airport in limited visibility due to marginal weather conditions. While completing a last turn to join the approach path, the twin engine aircraft crashed on the top of a hill located about 3 km short of runway. A pilot and a passenger were killed while 10 other occupants were injured.
Probable cause:
It was determined that the crew initiated the last turn prematurely, causing the aircraft to descent below the MDA in limited visibility. At the time of the accident, the aircraft deviated 3 km to the right of the approach path. Lack of visibility was a contributing factor.

After landing at Whale Cove Airport, the aircraft deviated to the left after a course of about 1,600 feet. It veered off runway, lost its undercarriage and came to rest. Both pilots escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
The aircraft deviated from the runway centerline after landing due to strong crosswinds gusting up to 31 knots. The certification limit for the aircraft in such conditions was 22 knots.

Aircraft flight hours:

Circumstances:
During initial takeoff climb the copilot who was manipulating the controls called for METO (maximum except takeoff) power. After the pilot-in-command set METO power, the left engine lost power. The PIC took the controls from the copilot and called for him to feather the left propeller. The copilot did not hear the call to feather the left propeller. Maintaining an indicated airspeed of 90 knots and wings level attitude, the airplane descended into trees and impacted a rural residential paved street. The cockpit area and main fuselage were consumed by a post crash fire. Examination of the throttle quadrant revealed the propeller control levers were forward, the mixture control levers were autorich, the throttle for the right engine was forward, and the throttle for the left engine was at idle. According to a FAA operations inspector maintaining 90 knots with the propeller not feathered would result in the aircraft descending. The pilot and copilot had not completed a proficiency check or flight check for the DC3 type aircraft within the previous 24 months. Examination of the left engine did not disclose any preexisting anomalies.
Probable cause:
The flight instructor's failure to use the single engine best angle of climb airspeed resulting in a loss of control of the aircraft. Factors were the loss of power to the left engine for undetermined reasons, the flight instructor not being qualified to be pilot-in-command in the DC3, his lack of recent experience in the DC3, and the lack of suitable terrain for the forced landing.

Circumstances:
During departure climb, the airplane experienced a loss of engine power. Emergency procedures were executed and a forced approach/landing was initiated to a field. While on the approach, the pilot observed a ditch running across the proposed landing pathway. He turned the airplane right to parallel the ditch. During the landing roll, the pilot attempted to avoid a building by intentionally ground looping the airplane. During this avoidance maneuver, the left wing struck the building. Examination of the airplane revealed that the engine had seized due to an internal failure. The reason for the engine's internal failure was not determined.
Probable cause:
Engine seizure for undetermined reasons. A factor was the lack of suitable terrain for the forced landing.

Circumstances:
The crew was completing an executive flight from Kaduna to Jos, carrying four crew members and eight passengers, among them Colonel Mohammed Wase. On approach to Jos Airport, the crew encountered limited visibility due to marginal weather conditions when the aircraft collided with a telecommunication antenna and crashed, bursting into flames. The aircraft was totally destroyed and all 12 occupants were killed.
Probable cause:
The following findings were reported:
- The antenna has been recently installed by the company Nitel in a prohibited area,
- The crew was unable to see and avoid the obstacles due to poor weather conditions,
- The aircraft was not properly aligned on the approach path due to a wrong calibration of the Jos VOR by 10°.
