Narrative:
A Skyward Fokker 50, registration 5Y-SIB, performing a cargo flight from Wajir to Nairobi-Wilson Airport was on downwind runway 07, when the crew received indication that the left main gear did not extend and lock in the down position. The crew aborted the approach and opted to extend downwind and then entered a hold, where it was confirmed the gear had not extended.
While taking off at Wajir runway 15 at 09:40, while passing 200 feet above ground level the crew noticed a flock of birds and experienced a bird strike, but decided to proceed on with the flight when they were satisfied with their safety review of the situation.
Visual inspection by the crew revealed a large bird carcass hanging from the left main landing gear. At 10:55 the crew requested for diversion to Nairobi-Jomo Kenyatta Airport as they declared full emergency landing and was cleared to join base runway 06.
The crew subsequently decided to perform a gear up landing and landed the aircraft on runway 06 at about 11:02 skidding to a halt 2 km from the threshold on the runway. No injuries were reported.
A post removal inspection revealed evidence of a bird strike lodged into the left main gear structure.

Probable Cause:

Probable Cause: "The cause of the accident was the failure of the left Main Landing Gear,MLG to extend during landing due to a bird strike which disabled proper functioning of the mechanical system that controls the opening and closing the door to the left MLG."
