There are tentative indications that the Colgan Air Bombardier Q400 which crashed on approach to Buffalo yesterday was just nine months old.
While authorities have yet to identify the airframe formally, a source points to the Pratt & Whitney PW150-powered aircraft as being serial number 4200, in service with Colgan Air as N200WQ.
Flight's ACAS database last entry for the aircraft lists it as being owned by Colgan Air, a subsidiary of US company Pinnacle Airlines.
Colgan Air operates as a Continental Connection carrier. Its Q400s were introduced last year under a 10-year agreement to fly for the US major.
Flight 3407 had been operating between Newark and Buffalo when it came down short of its destination, with no apparent survivors.
