Narrative:
Varig Flight 886 to Lima, Peru, experienced an uncontained failure of the HPC stage 3-9 spool in the No. 2 (right) General Electric CF6-80C2B2 engine during takeoff. The flight crew reported that at a speed of about 60 knots, they heard a loud bang. They rejected the takeoff and stopped the airplane on the runway. The copilot opened the right-side cockpit window to look out and advised the pilot that there was a fire around the right main landing gear. The flight crew reported that they then attempted to taxi clear of the fire but stopped the airplane on the runway again when they realized it was the engine that was on fire and ordered an evacuation. Although the flight crew discharged both fire bottles into the No. 2 engine nacelle, the fire continued until it was extinguished by airport fire department personnel.
Contributing factors (translated from Portuguese):
Material factor
(1) Design Deficiency - Contributed
The inspection by penetrating liquid, scheduled to be executed on the HPC stage 3-9 spool, failed to ensure the detection of cracks caused by DTF ("Dwell-Time Fatigue"), such as that caused the failure in this accident.
(2) Deficiency manufacturing - Contributed
The HPC stages 3-9 spool failure occurred because the existence of an area of quasi-cleavage, originating from the manufacturing process of the same.
