| Confidence Rating: |  Accident investigation report completed and information captured |
An uncontained failure of the right engine occurred as the airplane lifted off the runway and began its initial takeoff climb. The airplane returned to the departure airport for a single-engine landing, and emergency crews extinguished a fire confined to the right engine's hot section. The uncontained failure resulted from a fatigue crack in the combustion chamber outer case at the forward drain boss weld. Based on an analysis of fatigue striation measurements, a detectable crack existed at the forward drain boss weld when an on wing ultrasonic inspection of the boss was performed by company maintenance personnel in December 1995.
Probable Cause: The failure of company maintenance personnel to perform a proper inspection of the combustion chamber outer case, thus allowing a detectable crack to grow to a length at which the case ruptured.
