Circumstances:
On approach to Nairobi-Jomo Kenyatta Airport, the crew encountered limited visibility due to poor weather conditions. As the crew was unable to locate the runway, the captain decided to abandon the approach and initiated a go-around manoeuver. Few minutes later, while completing a second attempt to land, the aircraft descended below the glide when it struck power cables and crashed 4 km short of runway 06, bursting into flames. All 10 occupants were killed.
Probable cause:
It is believed that the crew descended below the MDA to establish a visual contact with the ground while approaching the airport in a 500 meters visibility due to fog. The crew failed to follow the published go-around procedures and at the time of the accident, the aircraft was not equipped with a GPWS system.

Circumstances:
On December 3, 1990, at 1345 est, Northwest flight 1482, a DC-9 (N3313L), and Northwest flight 299, a Boeing 727 (N278US), collided near the intersection of runway 09/27 and 03C/21C in dense fog at Detriot-Metropolitan-Wayne County Airport, MI. At the time of the collision, the B-727 was on its takeoff roll, and the DC-9 had just taxied onto the active runway. The B-727 was substantially damaged, and the DC-9 was destroyed. Seven of the 40 passengers and 1 crew member aboard the DC-9 received fatal injuries. None of the 146 passengers and 8 crewmembers aboard the B-727 were injured.
Probable cause:
Lack of proper crew coordination, including virtual reversal of roles by the DC-9 pilots, which led to their failure to stop taxiing and alert ground controller of their positional uncertainty in a timely manner before and after intruding onto the active runway. Contributing to cause of accident were:
- Deficiencies in ATC services provided by Detroit tower, including failure of ground control to take timely action to alert local controller to possible runway incursion, inadequate visibility observation, failure to use progressive taxi instructions low-visibility conditions, and issuance of inappropriate and confusing taxi instructions compounded by inadequate backup supervision for level of experience of staff on duty;
- Deficiencies in surface markings, signage and lighting at airport and failure of FAA surveillance to detect or correct any of these deficiencies;
- Failure of Northwest Airlines to provide adequate cockpit resource management training to line aircrews. Contributing to fatalities was inoperability of DC-9 internal tailcone release mechanism. Contributing to number and severity of injuries was failure of crew of DC-9 to properly execute the passenger evacuation.

Circumstances:
Following an uneventful flight from Krasnoyarsk, the crew started the approach to Dikson by night and marginal weather conditions. On short final, the aircraft was too high and landed too far down the runway with a tailwind component and at an excessive speed. Unable to stop within the remaining distance available, the aircraft overran, went through an embankment at a speed of 115 km/h and eventually came to rest in a ravine. All 35 occupants were rescued, among them 8 were injured. The aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration on part of the crew. The following contributing factors were reported:
- Excessive speed upon landing,
- Tailwind component,
- Lack of visibility,
- Snow squalls.

Circumstances:
On final approach, after being cleared to land, the pilot informed the controller that he might have to shut down an engine. He declined to declare an emergency or request assistance. On short final, the aircraft was observed to roll to the left and descent into the terrain. Subsequent examination revealed evidence that the left engine was not developing power, although the left propeller was not feathered. There was evidence that the right engine was producing high power during impact. No mechanical deficiency of the left engine or propeller was found. The pilot, sole on board, was killed.
Probable cause:
The pilot's improper emergency procedures by not feathering the left engine after it lost power and/or was shut down, and his failure to keep the aircraft at or above the minimum control airspeed (VMC), which resulted in a loss of aircraft control. A factor related to the accident was: an undetermined problem concerning the left engine that caused it to lose power or prompted the pilot to shut it down.
