Aircraft Accident/Incident Report

Colorado Sprngs, Colorado 80831
Thursday, May 7, 1998 21:30 MDT

NTSB Narrative Summary Released at Completion of Accident

Federal Express flight 1287 departed Colorado Springs, en route to Memphis, Tennessee. When the airplane was north of the airport and passing 8,500 feet msl, it struck a flock of large white birds, causing an uncontained no. 3 engine failure. There was also a loss of essential electrical power. The captain declared an emergency, returned to the Colorado Springs Airport, and made an uneventful landing. In addition to minor damage to the right side of the fuselage, visual inspection of the engine disclosed bird remains in and around the no. 3 engine. The outboard 4 inches of the first stage compressor blade separated, damaging the first and second stage compressor blades, stator blades, and inlet guide vanes. Shrapnel was ejected through the engine case at the 12 o'clock position, severing the no. 3 electrical bus wire bundle and puncturing the engine inlet anti-ice bleed air duct. The nose and upper engine cowling and thrust reverser were also damaged. The constant speed drive oil cooler was partially separated due to engine vibrations.

NTSB Probable Cause Narrative

An inadvertent inflight collision with a flock of large birds.
