A B737-300 WAS DISPATCHED IN NON COMPLIANCE WITH A #1 ENG COMBUSTION LINER CRACK OUT OF LIMITS.

Narrative

MAR/TUE/04; I WAS ASSIGNED TO ACFT; #1 ENG FOR SHAKEDOWN AND ROUTINE BORESCOPE. AT APPROX XA30 AFTER LETTING THE ENG COOL DOWN; I STARTED 'BORE.' I SAW SOME DAMAGE TO THE INNER COMBUSTION WALL. AT THIS POINT I ASKED INSPECTOR TO ALSO TAKE A LOOK. WE THEN DID A COLD SIDE INSPECTION TO SEE IF CRACKS WERE ON THAT SIDE; NONE WERE NOTED. AT THIS POINT WE CONTACTED OUR LEAD INSPECTOR; WHO; IN TURN; CONTACTED SUPVR. ASKED TO ALSO LOOK DUE TO HIS MANY YRS OF BORESCOPE WORK. AGREED THERE WAS DAMAGE THAT SHOULD BE WATCHED. CLOSED MOTOR. MAPPED DAMAGE ON PAPERWORK AND TURNED IN TO PRODUCTION WHO THEN FAXED TO ENGINEER. ON FRONT OF PAPERWORK PLACED NOTE 'ENG MAY NEED TO BE PUT ON WATCH STATUS.' WE HAD CHKED MAINT MANUAL AND BELIEVED THAT IT WAS WITHIN LIMITS. ENGINEER SAW RPT AND IT SAID IT WAS OUT OF LIMITS AND HAD ANOTHER 'BORE' DONE IN ZZZ. ENG WAS CHANGED AT THAT STATION. PWR PLANT ENGINEER WENT TO OFFICE LOCATED AT OTHER END OF HANGAR AND STARTED ASKING QUESTIONS ABOUT ENG. THE INSPECTORS INVOLVED IN THIS WERE NOT THERE; THIS AT APPROX XF30. THIS ACFT WAS AT GATE AND DEPARTED.
