Investigators have commenced a probe into an accident at Wilson airport, in western Nairobi, involving a Silverstone Air Services Fokker 50 turboprop.

The aircraft had been departing Wilson for Mombasa and onwards to Lamu at around 09:00 on 11 October.

Kenya Airports Authority says the aircraft "veered off the runway" during take-off. It came to rest on rough ground, in a patch of bushes, suffering substantial damage.

Two of the 55 occupants – comprising 50 passengers and five crew members – were injured, says the authority.

"We are currently working with the relevant authorities to assess the situation," says Silverstone Air.

It identifies the Fokker 50 involved as 5Y-IZO, which Cirium fleets data lists as a 1992 airframe originally delivered to Icelandair. It was leased by Silverstone in March last year.

Meteorological data from Wilson airport indicates good visibility and no adverse weather conditions.

Silverstone Air operates a mixed fleet which also includes Bombardier turboprops, and serves several domestic routes.
