A Fokker 50 operated by Silverstone Air Services veered off the runway during takeoff from runway 14 at Nairobi-Wilson Airport, Kenya. The aircraft was performing a scheduled flight from Nairobi-Wilson Airport to Mombasa, Lamu and back to Wilson Airport. At 09:02 local time during the takeoff roll on runway 14, the no.1 (left) engine ITT began to fluctuate, dropping from 707.8 to 175.8. The no.2 (right) engine ITT remained stable. The other parameters of both engines were stable. The no.1 engine lost power and the IAS dropped from after reaching 110 knots. Simultaneously the aircraft deviated to the right of the runway axis when it left the paved surface of the runway, before colliding with the airport perimeter fence. It then went through an embankment before coming to rest tilted to the right after the starboard wing made contact with a tree. The passengers were deplaned through the two left hand side front and rear exit doors. There were 50 passengers and five crew members on board. One passengers sustained serious injuries.
