Bird residue was found in the left engine of the Sabreliner that crashed during an aborted takeoff May 9 from Brownwood Regional Airport, Texas, according to the NTSBâs recently released factual report. After the airplane reached V1 the crew and passengers heard a âloud bangâ after which the airplane swerved to the left. The pilots lost directional control and the airplane went off the end of the runway, hit trees, crossed a road and came to rest in a field. The GE CF700-powered jet was substantially damaged but there were no serious injuries to those on board. On subsequent investigation, the NTSB said âsmall organic fibers that appeared to be from a bird were found on the combustion chamber mating flange and throughout the second-stage turbine nozzleâ of the left engine. The Safety Board also reported that while the 1978 twinjet (N972R) was equipped with a Fairchild Model A100 cockpit voice recorder, the recording was found to be of such âpoor qualityâ it was useless for accident investigation purposes.
