What was found
THE NR 2 ENGINE GAVE OFF A LOUD BANG AFTER TAKEOFF FROM SJO. THE BANG WAS FOLLOWED BY A RAPID RISE IN EGT AND LOSS OF THRUST. THE NR 2 ENGINE WAS SHUT DOWN AND THE AIRCRAFT WAS RETURNED TO SJO WHERE IT LANDED WITHOUT INCIDENT. A WALKAROUND INSPECTION FOUND NR 2 ENGINE FAN BLADE AND INLET COWL DAMAGE, A HOLE THROUGH THE RT HORIZONTAL STABILIZER, AND DAMAGE TO FLAP FAIRING. THE AIRCRAFT WAS TAKEN OUT OF SERVICE FOR REPAIRS AND IS UNDER GOING AN ENGINE CHANGE. ENGINEERING INVESTIGATION CONCLUDED THAT THE PRIMARY CAUSE OF ENGINE FAILURE WAS DUE TO A LOW CYCLE FATIGUE CRACK ON THE RADIUS OF THE FRONT LUG OF THE ANNULUS FILLER.
