preliminary report on the loss of a Fokker 100 operated by Air France
subsidiary Regional Airlines reveals that the co-pilot noticed birds passing the
aircraft during the take-off run, which ended in the aircraft failing to gain
height and crashing through the boundary fence.
investigators have found no evidence of a bird-strike in either of the two
Rolls-Royce Tay 650 engines and it remains uncertain why the aircraft crashed.
truck-driver on a public road was killed in the 25 January accident this year
when the aircraft, operating flight AF7775 to Paris, struck his vehicle after the overrun at Pau Airport in south-western France.
The 50 passengers and four crew
Bureau d’Enquetes et d’Analyses (BEA), in a newly-released
preliminary inquiry report, describes how the aircraft began its take-off run
on runway 13 just before 10:24 and that about three seconds before rotation,
the first officer, who was non-flying, commented: “Ah, sparrows.”
aircraft lifted off at a speed of 144kt (266km/h) but almost immediately banked
left up to 35º. The captain used stick and rudder to counter the movement, but
the aircraft then banked as far as 67º to the right, and finally 59º left. The
maximum height reached was 107ft at an angle of incidence of 17º.
the captain still controlling it, the aircraft touched down on the right-hand
gear to the right of the runway, bounced airborne again, before careering
through the airfield boundary, thrust-reversers deployed, and coming to a halt
in a field after its left-hand main-gear had struck the cabin of the truck
voice and data recorders worked well but the investigators have yet to find the
cause of the accident. They say there was no “smell, debris, or marks” to
indicate a bird-strike to either engine.
the crew did not request de-icing, neither did four of five crews of other
aircraft that departed in the preceding 40 minutes when the temperature was
near zero and light snow was intermittently falling.
