On approach to Nairobi-Jomo Kenyatta Airport, an aircraft struck power cables and crashed short of the runway during a second landing attempt, killing all 10 occupants. Official findings indicate the crew descended below the minimum descent altitude in low visibility and failed to follow go-around procedures.

Accident Sequence

While approaching Nairobi-Jomo Kenyatta Airport, the flight crew encountered limited visibility due to poor weather conditions. Unable to locate the runway, the captain decided to abandon the approach and initiated a go-around. Minutes later, during a second landing attempt, the aircraft descended below the glidepath, struck power cables, and crashed approximately 4 km short of runway 06. The impact resulted in a fire that engulfed the aircraft. All 10 occupants were killed.

Investigation Findings

Official findings determined that the crew descended below the minimum descent altitude (MDA) in an effort to establish visual contact with the ground. At the time of the accident, visibility was 500 meters due to fog. The crew failed to follow the published go-around procedures. Additionally, the aircraft was not equipped with a Ground Proximity Warning System (GPWS).

Probable Cause

The probable cause, as stated in the official findings, is that the crew descended below the MDA to establish visual contact with the ground while approaching the airport in 500 meters visibility due to fog. The crew failed to follow the published go-around procedures, and the aircraft was not equipped with a GPWS system.
