Narrative:
Mechanic went from chicago to new orleans to dress first stage fan blades on air carrier aircraft on oct/xx/95. Maintenance manual was used as maintenance reference. #3 fan blade may have been 'cropped' beyond maintenance manual overhaul version limits. Callback conversation with reporter revealed the following information: reporter stated that the fan blades were from a compressor disk off of a B737-200 engine which was put back in service after disk replacement. After the reporter checked with the FAA local office, other company personnel gave the reporter the impression that this bad disk was never a reality and was only a joke. Reporter further stated that he has been given harassment by his fellow workers. This was learned by reporter after he turned in this report at the suggestion of his safety officer. Even if this problem had occurred, it would no longer be a problem since the compressor fan was replaced after the ferry flight before the aircraft was returned to service.

Title: AN ACR MECH RPTS THAT A TURBINE ENG FAN BLADE WAS 'DRESSED DOWN' BELOW MAINT OVERHAUL LIMITS.
Narrative: MECH WENT FROM CHICAGO TO NEW ORLEANS TO DRESS FIRST STAGE FAN BLADES ON ACR ACFT ON OCT/XX/95. MAINT MANUAL WAS USED AS MAINT REF. #3 FAN BLADE MAY HAVE BEEN 'CROPPED' BEYOND MAINT MANUAL OVERHAUL VERSION LIMITS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE FAN BLADES WERE FROM A COMPRESSOR DISK OFF OF A B737-200 ENG WHICH WAS PUT BACK IN SVC AFTER DISK REPLACEMENT. AFTER THE RPTR CHKED WITH THE FAA LCL OFFICE, OTHER COMPANY PERSONNEL GAVE THE RPTR THE IMPRESSION THAT THIS BAD DISK WAS NEVER A REALITY AND WAS ONLY A JOKE. RPTR FURTHER STATED THAT HE HAS BEEN GIVEN HARASSMENT BY HIS FELLOW WORKERS. THIS WAS LEARNED BY RPTR AFTER HE TURNED IN THIS RPT AT THE SUGGESTION OF HIS SAFETY OFFICER. EVEN IF THIS PROB HAD OCCURRED, IT WOULD NO LONGER BE A PROB SINCE THE COMPRESSOR FAN WAS REPLACED AFTER THE FERRY FLT BEFORE THE ACFT WAS RETURNED TO SVC.
