Descripción:
At about 19:08 EDT Flight VJA 597 (Atlanta-Miami) took off from runway 27R. During the take-off roll a loud bang was heard, and the crew of a following aircraft informed the ValuJet crew that they had an engine fire.
The take-off was aborted immediately, but shrapnel form the uncontained engine failure penetrated the right engine main fuel line. A cabin fire erupted from the fuel that was sprayed out of the fuel line. The DC-9 was stopped on the runway, and the occupants evacuated through the forward doors and the over wing exits.
The engine failed due to a fatigue crack that had originated at a small corrosion pit on the 7th stage HP compressor disk. The corrosion had not been detected when the effected part had been inspected during overhaul by THY in 1991.


PROBABLE CAUSE: "The failure of Turk Hava Yollari maintenance and inspection personnel to perform a proper inspection of a 7th stage high compressor disk, thus allowing the detectable crack to grow to a length at which the disk ruptured, under normal operating conditions, propelling engine fragments into the fuselage; the fragments severed the right engine main fuel line, which resulted in a fire that rapidly engulfed the cabin area. The lack of an adequate record-keeping system and the failure to use "process sheets" to document the step-by-step overhaul/inspection procedures contributed to the failure to detect the crack and, thus, to the accident."
