Narrative

THE PLT WROTE UP '#1 ENG SLOW TO ACCELERATE FOR TKOF. #1 ENG BACKFIRES IN THRUST REVERSER DURING LNDG ROLL -- LOUD POP AND FLASH.' CORRECTIVE ACTION; AS I PERCEIVED; WAS A FUEL SCHEDULING PROB. WE PERFORMED A VARIABLE BLEED VALVE FEEDBACK CABLE RIG CHK PER MAINT MANUAL. WE PERFORMED A TIMED ACCELERATION CHK PER MAINT MANUAL. NO PROBS WERE NOTED. I WAS INFORMED TODAY (APR/TUE/02) THAT A BORESCOPE INSPECTION MAY HAVE BEEN REQUIRED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE LOGBOOK RPT ON THE ENG WAS #1 ENG WAS SLOW TO ACCELERATE AND BACKFIRES IN REVERSE. THE RPTR SAID BOTH TECHNICIANS AGREED THIS WAS A FUEL SCHEDULING PROB AND USED THE MAINT MANUAL CORRECTIVE ACTION PROCS. THE RPTR STATED A VARIABLE BLEED VALVE RIG CHK AND ADJUSTMENT WAS IN ORDER AND THIS WAS ACCOMPLISHED THE FEEDBACK CABLE NEEDING A SMALL ADJUSTMENT. THE RPTR SAID THE ACFT WAS TAXIED TO A RUN PAD AND THE ACCELERATION WAS CHKED AND FOUND WITHIN LIMITS. THE RPTR STATED THE AIRPLANE WAS THEN RETURNED TO SVC. THE RPTR SAID ABOUT 1 WK LATER; MAINT CTL ADVISED LCL MGMNT A BORESCOPE PROC SHOULD HAVE BEEN PERFORMED. THE RPTR STATED THE MAINT MANUAL DID NOT REQUIRE A BORESCOPE PROC. THE RPTR SAID THE ENG OPERATED FOR 10 WKS BEFORE IT HIT AGAIN; BUT THE LOG RPT WAS DIFFERENT AND STATED THE ENG WAS SLOW TO ACCELERATE AND STALLS IN REVERSE. THE RPTR STATED A MAIN ENG FUEL CTL WAS REPLACED AND OPERATED SINCE WITH NO PROBS.
