Factual Report: Birdstrike Might Be Cause Of Sabreliner Accident
Rockwell International NA-265-80 Sabreliner, Brownwood, Texas, May 9, 2005–Debris, possibly from a bird, was found on the combustion chamber mating flange and throughout the second-stage turbine nozzle of the left GE CF700 of the Sabreliner that crashed on takeoff from Brownwood Regional Airport.
According to the NTSB factual report on the accident, investigators also found residue on the inlet frame assembly and on five of the first-stage compressor blades, the tips of which were bent and deformed. ive of the first-stage turbine vanes were bent slightly on the outboard tips. Investigators found dust throughout the engine.
The Sabreliner was taking off and had reached V1 when the crew and passengers heard a “loud bang.” The captain said he immediately aborted the takeoff because of “rapidly losing directional control” and applied thrust reversers to keep the airplane “as centered on the runway as possible.” The airplane lost power, swerved to the left and went off the end of Runway 17, hitting trees and crossing a road before plowing into a field and stopping approximately 1,300 feet beyond the end of the runway.
The Sabreliner was substantially damaged, but the 4,120-hour ATP pilot, the commercial copilot and three passengers were not injured. Operated by Compass Acquisitions and Development of Dallas, the airplane was en route to Mesquite, Nev. The cockpit voice recording was of such poor quality that it was no help to the investigators
