Narrative:

New company position. Dealing with a tech I'm not familiar with. While supervising a repair on aircraft X in ZZZ; a miscom occurred on location of damage to the #2 engine fan blades which would have required a borescope inspection of the gas path per maintenance manual supplement 71-00-47 fig 102. Verbal description of the damage and pictures sent didn't indicate damage inboard of the midspan shroud. When aircraft arrived in ZZZ1 further inspection of the engine caused suspicion. The mechanic didn't relay all the locations of the damage to the fan blades. After contacting the mechanic today I had him facsimile a diagram of the locations he blended on the blades and found he had blended within the midspan shroud area. Received call from ZZZ saying the #2 engine had FOD damage. The mechanic said he had damage to several blades and the acoustical liner. Maintenance manual reference were sent in order for him to accomplish the repairs. The inlet cowl was determined to be outside the maintenance manual limits and therefore required repair. He sent pictures of the damage he saw. He blended the blades he indicated were damaged; and mapped out the inlet cowl damage in order to submit to engineering. When it was determined the damage to the cowl was not going to be fixed we decided to ferry the aircraft to ZZZ1 for repair of the cowl. Because all damage was understood to be outside the midspan shroud I believed it was unnecessary to accomplish a borescope. Callback conversation with reporter revealed the following information: reporter stated this was a cfm-56 type engine.

Title: A B737-400 ACFT WAS FERRIED TO MAINT BASE WITHOUT THE REQUIRED BORESCOPE INSPECTION OF THE #2 ENG. MISCOMMUNICATION BETWEEN THE LINE MECHANIC AND BASE SUPERVISOR ABOUT DAMAGE LOCATION ON FAN BLADES.

Narrative: NEW COMPANY POS. DEALING WITH A TECH I'M NOT FAMILIAR WITH. WHILE SUPERVISING A REPAIR ON ACFT X IN ZZZ; A MISCOM OCCURRED ON LOCATION OF DAMAGE TO THE #2 ENG FAN BLADES WHICH WOULD HAVE REQUIRED A BORESCOPE INSPECTION OF THE GAS PATH PER MAINT MANUAL SUPPLEMENT 71-00-47 FIG 102. VERBAL DESCRIPTION OF THE DAMAGE AND PICTURES SENT DIDN'T INDICATE DAMAGE INBOARD OF THE MIDSPAN SHROUD. WHEN ACFT ARRIVED IN ZZZ1 FURTHER INSPECTION OF THE ENG CAUSED SUSPICION. THE MECH DIDN'T RELAY ALL THE LOCATIONS OF THE DAMAGE TO THE FAN BLADES. AFTER CONTACTING THE MECH TODAY I HAD HIM FAX A DIAGRAM OF THE LOCATIONS HE BLENDED ON THE BLADES AND FOUND HE HAD BLENDED WITHIN THE MIDSPAN SHROUD AREA. RECEIVED CALL FROM ZZZ SAYING THE #2 ENG HAD FOD DAMAGE. THE MECH SAID HE HAD DAMAGE TO SEVERAL BLADES AND THE ACOUSTICAL LINER. MAINT MANUAL REF WERE SENT IN ORDER FOR HIM TO ACCOMPLISH THE REPAIRS. THE INLET COWL WAS DETERMINED TO BE OUTSIDE THE MAINT MANUAL LIMITS AND THEREFORE REQUIRED REPAIR. HE SENT PICTURES OF THE DAMAGE HE SAW. HE BLENDED THE BLADES HE INDICATED WERE DAMAGED; AND MAPPED OUT THE INLET COWL DAMAGE IN ORDER TO SUBMIT TO ENGINEERING. WHEN IT WAS DETERMINED THE DAMAGE TO THE COWL WAS NOT GOING TO BE FIXED WE DECIDED TO FERRY THE ACFT TO ZZZ1 FOR REPAIR OF THE COWL. BECAUSE ALL DAMAGE WAS UNDERSTOOD TO BE OUTSIDE THE MIDSPAN SHROUD I BELIEVED IT WAS UNNECESSARY TO ACCOMPLISH A BORESCOPE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: REPORTER STATED THIS WAS A CFM-56 TYPE ENGINE.
