AN A320 PILOT REPORTS ON THE UNPROFESSIONAL ATTITUDE AND DEMEANOR OF A MAINTENANCE SUPERVISOR AND MECHANIC; AFTER CALLING MAINTENANCE CONTROL ABOUT NUMEROUS UNDOCUMENTED LOCALIZED DENTS ON THE RIGHT LOWER SIDE OF THE RIGHT HORIZONTAL STABILIZER.

Narrative

DURING MY WALKAROUND; I DISCOVERED NUMEROUS LOCALIZED DENTS ON THE UNDERNEATH SIDE OF THE R SIDE OF THE HORIZ STABILIZER. THE ACFT SKIN REMINDED ME OF A GOLF BALL. THERE WERE APPROX 15-20 SMALL DENTS; APPROX 10 INCHES INBOARD; IN A CIRCULAR AREA WITH A 7-10 INCH DIAMETER. I WAS SURPRISED NOT TO SEE A STICKER (AKA 'DENT DOOR') PLACED BY MAINT AFTER INSPECTING THE AREA; AS I THOUGHT THE DAMAGE WAS VERY NOTICEABLE. MY MAIN CONCERN WAS THE POSSIBILITY OF INTERNAL STRUCTURAL DAMAGE TO THE STABILIZER FAIRING. UPON RETURNING TO THE COCKPIT; I TOLD THE CAPT ABOUT THE DAMAGE. AS THERE WAS NOTHING MENTIONED ABOUT THIS IN OUR MAINT LOG HISTORY PAPERWORK; HE TOLD ME TO CALL MAINT TO INQUIRE ABOUT THE LONG(ER) TERM ACFT HISTORY. I CALLED THE LOCAL MAINT CTL FREQ; AND WAS TOLD BY THE MECH WHO ANSWERED THAT HE WOULD INVESTIGATE AND GET BACK TO US. WHEN THE MECH CALLED BACK SEVERAL MINS LATER; HE STATED HIS SURPRISE THAT THERE WAS ABSOLUTELY NO RECORD OF ANY SUCH DAMAGE; CF OR DF ITEM FOR OUR ACFT AND THAT SOMEONE WOULD NEED TO COME OUT AND TAKE A LOOK AT IT. I ASKED IF HE WANTED US TO SEND A MAINT REQUEST CODE OR HAD HE ALREADY DONE SO? HE REQUESTED THAT WE ENTER THE LOG ITEM BY SENDING THE WRITE-UP VIA ACARS. I ENTERED THE WRITE-UP: UNDERNEATH SIDE OF R SIDE HORIZ STABILIZER HAS NUMEROUS DENTS -- POSSIBLE HAIL DAMAGE. SHORTLY THEREAFTER; A MECH STOPPED BY THE COCKPIT AND ASKED ME TO COME OUTSIDE AND POINT OUT THE AREA WE/I WAS REFERRING TO. I CAME OUTSIDE AND POINTED OUT THE AREA. I NOTICED IMMEDIATELY A MAINT SUPVR WHO WAS OUTSIDE NEAR THE TAIL WHO WAS ON HIS CELL PHONE AND HAD A CLIPBOARD AND WAS MAKING NOTES. HE STOOD AWAY FROM US THE ENTIRE TIME AND DID NOT ENGAGE IN ANY KIND OF DISCUSSION WITH ME. THE MECH SAID 'THAT'S FIBERGLASS.' I SAID 'I KNOW.' HE SAID 'THAT'S INTERNAL DAMAGE.' I SAID 'THAT IS WHAT IT LOOKED LIKE TO ME TOO; WHICH IS WHAT MOST CONCERNED ME.' THEN HE SAID; 'DO YOU SEE THE AREA THAT HAS BEEN PAINTED ALONG THE OUTER EDGE OF THE FAIRING?' I SAID 'YES.' HE SAID 'THAT'S THE REPAIR.' I MENTIONED THAT I WAS SURPRISED THAT THE CTLR I TALKED TO OVER THE RADIO DIDN'T HAVE ANY RECORD IN THE ARCHIVES OF THE DAMAGE AND/OR SUBSEQUENT REPAIR. HE SAID 'WELL; HIS INFO ONLY GOES BACK 30 DAYS!' I SAID; 'WELL; AS WE HAVE NO OFFICIAL RECORD OF THIS HAVING BEEN RPTED OR REPAIRED AND SINCE YOU'RE ALREADY OUT HERE; WOULD YOU PLEASE TAKE A QUICK LOOK; SO THAT WE WILL KNOW; FOR SURE; IT'S OK?' HE HUFFED AND TURNED TO GO UP ON THE 'CHERRY PICKER' WITHOUT ANY REPLY. I TURNED AND STARTED TO WALK AWAY AS I WAS GOING TO RETURN TO THE COCKPIT; THEN CHANGED MY MIND AND DECIDED TO WATCH AND MAKE SURE THAT THE MECH DID IN FACT INSPECT THE AREA. I WAS ABOUT 20 FT AWAY WHEN I TURNED AROUND; SAW THE MECH TALKING TO THE SUPVR; SHAKING HIS HEAD AND LAUGHING. AFTER HE INSPECTED THE AREA; THE MECH TOLD ME THAT IT WAS FINE AND THAT IT DID LOOK LIKE THE PAINT HAD BEEN DONE AFTER THE DENTS HAD HAPPENED. THIS WAS NOT EVIDENT TO ME FROM THE GND (PERHAPS AT ANOTHER TIME I CAN LEARN HOW PAINT IS SUFFICIENT TO REPAIR INTERNAL STRUCTURAL DAMAGE TO ACFT PARTS). I HAVE 2 ISSUES WITH THIS SITUATION. FIRST OF ALL; I FIND IT DISTURBING (IF IT IS IN FACT TRUE); THAT MAINT CANNOT ACCESS RECORDS OF DAMAGE AND REPAIR TO ANY ACFT BEYOND 30 DAYS. IF THIS IS TRUE; A BETTER SYSTEM SHOULD BE CREATED. AT THE BOTTOM OF OUR LOG HISTORY; WE SHOULD HAVE A LIST OF EACH EXTERNAL ITEM WHERE ANY REPAIR DOES NOT TOTALLY CORRECT ALL EVIDENCE OF THE ORIGINAL ISSUE/DAMAGE; SO EACH CREW WILL HAVE THE INFO AND KNOW IT IS NOT A NEW ISSUE. SECOND; I FOUND THE WAY I WAS TREATED TO BE VERY UNPROFESSIONAL AND DEMEANING. THE MECH MIGHT AS WELL HAVE SAID; 'YOU DON'T KNOW ANYTHING! WHY ARE YOU WASTING MY TIME?' THE DEMEANOR OF BOTH THE MECH AND SUPVR CERTAINLY SEEMED TO SAY THAT. IF; IN MY PROFESSIONAL JUDGEMENT; I HADN'T THOUGHT THE ITEM WAS A LEGITIMATE CONCERN; I WOULD NOT HAVE MENTIONED IT TO THE CAPT; MUCH LESS TO MAINT. I FELT THAT THEIR TREATMENT OF ME WAS INTENDED TO SERVE AS A DETERRENT FOR FUTURE WRITE-UPS.
