Narrative

POSTFLT CREW (IN REMOTE LOCATION) CALLED MAINT CTL WITH A DISCREPANCY. CAPT'S HEADSET QUIT WORKING INFLT. CAPT STATED HE SWAPPED THE HEADSETS WITH THE OBSERVER'S SEAT. INTERESTINGLY ENOUGH; HEADSETS ARE BOLTED DOWN ON OPERATOR'S ACFT TO PREVENT THEFT (REQUIRES TOOLING). CAPT THEN ASKED TO DEFER THE INOP HEADSET. MAINT CTLR THEN STATED THE ACTION TAKEN BY THE CREW IS ACTUALLY A MAINT FUNCTION AND REQUIRES A MECH TO BE CALLED OUT (COMPANY POLICY). PLT WAS SURPRISED THIS NEEDED TO TAKE PLACE. MAINT CTLR CALLED THE APPROVAL ON CALL VENDOR AS DIRECTED IN COMPANY GMM/COMPUTER. THE ONE AND ONLY MECH IN THE ON CALL VENDOR LIST WAS NOT AVAILABLE (LATER LEARNED MECH OUT FOR MEDICAL). THE INDIVIDUAL THAT MAINT CTL SPOKE WITH WAS THE GENERAL MGR ON THE APPROVED ON CALL VENDOR AND THAT HE (INSISTED); THE GENERAL MGR WOULD BE ABLE TO TAKE CARE OF THE OPEN DISCREPANCY PERTAINING TO CAPT'S HEADSET INOP. THE GENERAL MGR OF THE APPROVED VENDOR THEN ARRIVED AT THE ACFT. MAINT CTL DIRECTED THE INDIVIDUAL TO DOUBLECHK THE MAINT WORK THE CREW HAD PERFORMED INFLT; THEN PERFORM THE REQUIRED OPS CHKS AS PER THE FAX'ED MAINT MANUAL COPIES AND DEFER THE OBSERVER SEAT AND ASSOCIATED EQUIP. ONCE THE LOGBOOK WAS SIGNED OFF; MAINT CTL ASKED THE GENERAL MGR TO FAX HIS LICENSE CREDENTIALS TO MAINT CTL PRIOR TO THE ACFT DEPARTING (OPERATOR OF ACFT POLICY). AFTER REVIEWING THE PAPERWORK OF THE INDIVIDUAL; TO SEE IN FACT WHO HE SAID HE IS; TURNED OUT HE WAS A CERTIFIED REPAIRMAN WITH AN FCC LICENSE; NOT A LICENSE AIRFRAME AND PWR PLANT MECH (OPERATOR OF ACFT REQUIRES A&P FOR LOGBOOK ENTRIES). REALIZING A DISCREPANCY ON LICENSE REQUIREMENTS THE MAINT CTLR QUICKLY NOTIFIED THE DISPATCHER; DISPATCH SUPVR; GATE AGENT WORKING THE ACFT; SHIFT MGR OF MAINT CTL AND THE GENERAL MGR OF MAINT CTL TO STOP THE ACFT UNTIL THE APPROVED ON CALL VENDOR'S PAPERWORK WAS FURTHER REVIEWED. IT APPEARED ALL PARTIES NOTIFIED WERE THE LEAST CONCERNED. THE ACFT HAD DEPARTED. AFTER A CONFERENCE WITH THE GENERAL MGR OF MAINT CTL IT WAS DECIDED BY THE GENERAL MGR OF MAINT CTL THE WORK PERFORMED BY THE APPROVED VENDOR WAS LEGAL EVEN THOUGH THE OPERATOR OF THE ACFT'S (GMM) REQUIRES AIRFRAME AND POWERPLANT MECHS TO SIGN OFF LOGBOOKS. THE CONCERNS BY THE MAINT CTLR THEN CONSIDERED THIS A CLOSED SUBJECT.
