Analysis

Captain heard a muffled explosion accompanied by a moderate left yaw and 'a deterioration of readings on #1 engine' shortly after takeoff. Acft returned for an uneventful landing. Examination revealed that the engine failure initiated in 'the T3 disk/blades area.' Metallurgical examination disclosed the fatigue failure of the 3rd stage turbine blade was most probably induced by rubbing btw the turbine shroud and the outer air seal.
