A B737-200 WAS DISPATCHED IN NON COMPLIANCE WITH #2 ENG REPAIRED BUT NO REQUIRED INSPECTION ACCOMPLISHED.

Narrative

THE ACFT #2 ENG OIL FILTER HAD A LEAK THAT WAS BEING REPAIRED ON Y SHIFT. THERE IS A TYPICAL REPAIR TO SLEEVE THE OIL FILTER CAVITY. THE REPAIR CALLS FOR A MECH TO REMOVE FILTERS AND A MACHINIST TO SKIM CUT THE FILTER CAVITY FOR ROUNDNESS THEN CALL FOR AN INSPECTOR TO ACCOMPLISH AN FINAL PWRPLANT INSPECTION. THEN IF NO CRACKS ARE FOUND THE MECH RESLEEVES AND PRESSURE TESTS AT A GIVEN PSI FOR 10 MINS; REINSTALLS FILTER AND CAP; TORQUE STUDS; THEN REQUESTS AN ENG RUN FOR LEAK CHK. THE MACHINIST DID NOT MAKE THE SKIM CUT BECAUSE THE HOLE WAS NOT OUT OF ROUND; SO HE DIDN'T CALL FOR AN INSPECTOR TO FINAL PWRPLANT INSPECTION THE OIL CAVITY. AFTER SHIFT TURNOVER; THE X SHIFT MECH DID THE PRESSURE TEST AND REINSTALLED THE FILTER AND CAP AND HAD THE ENG RUN LEAK TEST ACCOMPLISHED. AT THIS TIME THE INSPECTION SUPVR WAS REQUESTED BY THE LINE SUPVR TO SEND AN INSPECTOR TO SIGN OFF WORK ACCOMPLISHED IN THE ACFT LOGBOOK. PER GEAR BOX SHOP AND MACHINE SHOP TURNOVERS 'ALL' WORK HAD BEEN ACCOMPLISHED PER THE TYPICAL REPAIR. THE Z SHIFT INSPECTOR SIGNED THE ACFT LOGBOOK AS TO THE ACCOMPLISHMENT OF THE FINAL PWRPLANT INSPECTION. THEN WONDERING WHY THE Y SHIFT INSPECTOR DIDN'T SIGN OFF FOR THE FINAL PWRPLANT INSPECTION; HE CALLED HIM AT HOME AT APPROX XA30; AT WHICH TIME HE INFORMED THE Z SHIFT INSPECTOR THAT HE NEVER DID THE FINAL PWRPLANT INSPECTION. AT THIS TIME THE INSPECTION SUPVR WAS MADE AWARE OF THE NEW DEVELOPMENT. WE TRIED TO CALL THE Y SHIFT MACHINIST TO SEE IF HE GOT AN INSPECTOR FROM ANOTHER AREA TO ACCOMPLISH THE FINAL PWRPLANT INSPECTION AND GOT NO RETURN PHONE CALL. IT WAS NOW SHIFT CHANGE FROM Y TO X SHIFT. THE ACFT HAD BEEN FLOWN WITHOUT INCIDENT FOR THE NEXT DAY'S SVC. WE REQUESTED THE X SHIFT INSPECTION SUPVR TO TRY TO FOLLOW UP WITH CONTACTING THE MACHINIST FOR MORE INFO. UPON RETURNING TO WORK THE NEXT DAY THE Y SHIFT INSPECTOR WAS INFORMED THAT NO FINAL PWRPLANT INSPECTION HAD EVER BEEN ACCOMPLISHED BY ANY OTHER INSPECTOR AND THAT HIS LOGBOOK ENTRY WAS BOGUS.
