Circumstances:
While approaching Paris-Roissy-CDG Airport by night, at a distance of 13 km from runway 27 threshold, the crew was instructed by ATC to modify the approach trajectory and to descent to runway 28. This late request was necessary because runway 27 was just closed to traffic after a Korean Air B747 contacted the runway surface with its engine n°1. While completing a left turn, the airplane lost height and crashed in a field located 1,800 metres short of runway. Four passengers were killed while 19 other occupants were injured. The aircraft was destroyed. At the time of the accident, the visibility was reduced between 700 and 1,400 metres due to light fog and rain. The copilot was in command and it is believed the crew was disturbed by the late runway change. While on descent heading 265°, 100 seconds before FDR stopped recording, at an altitude of 1,600 feet and a speed of 170 knots, both engine torques were at 20%. Twenty seconds later, both engines torque dropped to zero and the automatic pilot system was deactivated. At this time, the flaps were retracted. The sink rate increased then the aircraft entered a nose-up attitude with its speed decreasing. The aircraft struck the ground at a speed of 110 knots and crashed.

Circumstances:
During the approach, the 1st officer (FO) asked the captain if he wanted to '...pop the boots?' to remove ice off the wings. The capt responded '...it's going to the hangar. I'll run'em on the ground...' The FO retarded power over the threshold and the sink rate increased; the capt observed 900 fpm. The FO applied additional back pressure on the yoke, but it was inadequate to arrest the high sink rate. Additional back pressure was applied, and the stall horn sounded followed shortly thereafter by the captain stating 'I got it.' During the hard landing the right main landing gear broke, the fuel tank ruptured, and the right wing rear spar bent upward. Aprx 18 hrs after the accident, 3/16 inch of rime mixed with clear ice was observed on the leading edges of the wing, horizontal stab, and vertical stab. The ice had finger-like protrusions positioned vertically to the wing surfaces. The company's line ops manual does not discuss flight characteristics or landing techniques specific to wing ice. Neither pilot had received company's current crm training.
Probable cause:
The first officer's failure to maintain a proper descent rate during the landing, and the captain's inadequate supervision by not taking timely action to ensure a safe landing. Factors which contributed to the accident were: the company's failure to provide adequate training on the airplane's flight characteristics and/or handling techniques under conditions of wing ice contamination, the company's failure to assure that both pilots had received the current crew resource management (crm) training, and the existing weather conditions which resulted in an accumulation of ice on the airplane's wing.

Circumstances:
Following an uneventful flight from Benghazi, the crew was cleared to start the descent to Tripoli Airport. Due to military traffic, the crew was instructed to hold over the Papa Echo beacon located 4,1 DME from runway 27 threshold. At an altitude of 3,000 feet, the Boeing 727 collided with a Libyan Air Force MiG-23 that just took off from Tripoli Airport. The fighter struck the tail of the Boeing that entered a dive and crashed 9 km from the airport after the tail separated. All 157 occupants were killed while both pilots on board the fighter ejected safely.

Circumstances:
After takeoff from Alotau Airport, the pilot followed the published departure procedure for about 17 km when he initiated a turn to the left bound to the northwest, always below clouds. Then, the aircraft entered clouds when, less than two minutes later, it struck the slope of a mountain located some 25 km from Alotau. The aircraft was destroyed and all six occupants were killed.
Probable cause:
Controlled flight into terrain after the pilot was flying under VFR mode in IMC conditions.

Circumstances:
During the second ILS approach the airplane descended below the glidepath and impacted the terrain 2,500 feet short of the intended landing runway. The pilot indicated that a failure in the approach lighting system contributed to the accident. A post accident functional check of the approach lighting system failed to reveal any anomalies.
Probable cause:
The pilot-in-command's failure to maintain a proper glidepath.

Circumstances:
En route to Goma, while cruising at FL190, the crew was cleared to descent successively to FL150, FL110 then FL085. Preparing for an approach to runway 36, the crew descended prematurely when, at an altitude of 8,800 feet, the aircraft struck the slope of a mountain located 40 km southwest of Goma. The aircraft disintegrated on impact and all 37 occupants were killed.
Probable cause:
For unknown reasons, the crew failed to follow the published approach procedures and initiated the descent prematurely, causing the aircraft to struck the ground. The minimum altitude of 8,500 feet could be reached only after the last turn completed between 19 and 25 km from the runway threshold.

Circumstances:
The single engine airplane was completing a flight from Ventsy (krai of Krasnodar) to Maykop, carrying two pilots and one mechanic. On approach to Maykop Airport, the crew encountered below minima weather conditions with clouds down to 100 metres and a visibility of 1 km. The crew was unable to establish a visual contact with the runway and when ATC suggested the crew to return to Ventsy, the crew said he was short of fuel. Shortly later, the engine failed; the aircraft lost height and crashed in an open field located 3 km from the airport, bursting into flames. All three occupants were killed.
Probable cause:
Engine failure due to fuel exhaustion. Weather bulletin transmitted to crew prior to departure from Ventsy was not relevant and did not reflect the actual situation in Maykop. Also ATC failed to transmit suitable information to the crew.

Circumstances:
The approach and landing to Yerevan-Zvartnots Airport was completed in poor weather conditions. Upon landing, the aircraft was not properly aligned with the centerline and landed too far to the right of the runway. Out of control, it veered off runway and eventually collided with a concrete wall. All 154 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
It was determined that the aircraft was not properly aligned with the runway centerline upon landing after the crew mistook the runway edge lights with the runway centerline lights.
