Détails:
A CRJ-200ER, N622BR, operating as Atlantic Coast Airlines (ACA) flight 7682, struck two wild turkeys while initiating a takeoff from runway 30 at Washington Dulles International Airport (IAD). None of the 3 crewmembers or 50 passengers on board was injured. The airplane sustained damage to the number-two engine inlet, the first officer's windshield, and a 14- by 4-inch section of fuselage skin just below the windshield seal on the first officer's side.
The captain reported that the airplane was on departure roll and had accelerated past 80 knots when a flock of birds began to fly south over the runway. The airplane was traveling at approximately 110 knots when one of the birds hit the airplane, cracking the first officer's windshield and causing a few shards of glass to fall into the cockpit and onto the first officer. The captain immediately rejected the takeoff and stopped on the runway to assess the damage.

A postflight inspection by maintenance personnel revealed that the airplane had struck two wild turkeys. One turkey hit the intake of the number-two engine, slightly damaging the forward lip of the engine intake cowl. No bird remains went through the engine. The other turkey hit just below the first officer's windshield, where a turkey leg and foot were still lodged. Closer examination of the airplane revealed that the second turkey hit the nose sheet metal at the base of the first officer's windshield, bending the windshield support structure and causing the windshield to crack upward from that location. The second turkey penetrated the area beneath the lower support structure, went through the pressure bulkhead, and entered the back of the instrument panel but did not penetrate either the windshield or its supporting structure.

Probable Cause:

PROBABLE CAUSE: "The airplane's collision with two wild turkeys."
