Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
Shortly after lift-off, the flt crew heard a loud noise (similar, but louder than a tire blow-out) as the #1 eng failed. They secured the #1 eng, remained in the traffic pattern & landed on the same rwy. After landing, an exam revealed the combustion chamber outer case, pn 616315, had failed from low cycle fatigue. The fatigue had propagated from a bolt holeon the rear flange & progressed forward until it reached a critical length, then the remaining fracture was from tensile overload. Nickel-cadmium plating was found in the fatigue cracked area. The case was last replated after it was modified, aprx 5152 flt hrs prior to the acdnt. Pratt & whitney engine repair manual 72-42-11 prohibits the nickel-cadmium plating of the front & rear case flange bolt holes.
