Narrative

SHORTLY AFTER TKOF (20-30 MINS); I WAS IN THE FIRST CLASS GALLEY SETTING UP FOR MEAL/BEVERAGE SVC IN FIRST CLASS; WHEN THE PURSER NOTICED THE DOOR AT 1L HAD BECOME DISARMED. IT DID IT SPONTANEOUSLY. THE PURSER (FLT ATTENDANT #1) NOTIFIED ME AND WE TALKED ABOUT IT AND I CONFIRMED THAT I HAD OBSERVED HER ARM THE SLIDE AT PUSHBACK. SHE NOTIFIED THE COCKPIT CREW. THERE WAS QUITE A LAG IN THEIR RESPONSE AND BY THE TIME THEY CAME OUT; THE HANDLE TO OPEN THE DOOR HAD STARTED TO RISE AWAY FROM THE FUSELAGE. IT ALSO WAS BOUNCING UP AND DOWN. THE COCKPIT CREW NOTIFIED THE COMPANY; THEY NOTIFIED US TO LAND AT JFK TO HAVE MAINT LOOK AT IT. THE CAPT DID WANT TO TRY TO MOVE IT. WE TOLD HIM WE WERE NOT COMFORTABLE WITH THAT IDEA AS HE WANTED TO TRY TO MOVE THE ARMING MECHANISM WITH A KNIFE. WE POINTED OUT THAT IF HE DROPPED THE KNIFE INTO THE INSIDE OF THE DOOR; IT COULD JAM THE OPENING MECHANISM. WE DID LAND AT JFK. PRIOR TO THAT; THE PURSER WAS ABLE TO ARM THE DOOR. THE MECHS COULD NOT DUPLICATE THE SET OF EVENTS ON THE GND AND COULD FIND NOTHING WRONG WITH THE DOOR. THEY DID MENTION THAT THERE APPEARED TO BE MARKS ON THE OUTSIDE OF THE DOOR FRAME THAT COULD POSSIBLY INDICATE A PREVIOUS PROB. WE LEFT JFK AND HAD NO MORE PROBS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT THE PURSER HAD HAD A HARD TIME ARMING THE DOOR IN RALEIGH; BUT MANAGED TO ARM IT. AFTER THE CAPT HAD LOOKED AT THE DOOR; THEY HAD A FLT ATTENDANT SIT IN A JUMP SEAT NEXT TO THE DOOR TO CONSTANTLY HOLD THE DOOR HANDLE DOWN. WHEN THEY REACHED A LOWER ALT AND THE PRESSURE INSIDE AND OUTSIDE HAD EQUALIZED; THE PURSER WAS THEN ABLE TO ARM THE DOOR. THE MECHS; WHO LOOKED AT THE DOOR IN JFK; TOOK INTO CONSIDERATION THE PROB THAT THE PURSER HAD ARMING THE DOOR ON THE GND; THE FACT THAT THE HANDLE WAS RISING ON THE OUTSIDE OF THE DOOR INFLT; AND ALONG WITH THE NOTCHES ON THE DOOR SEAL; THEORIZED THAT THE AGENT HAD NEVER COMPLETELY SHUT THE DOOR ON THE GND. SUPPLEMENTAL INFO FROM ACN 461213: I WAS INSTRUCTED TO HOLD THE HANDLE DOWN IN THE CLOSED POS TILL THE AIR NOISE STOPPED AND/OR LNDG. THE NOISE STOPPED ONCE WE DSNDED BY DOWN TO 10000 FT. THE B767 DOORS (ALL) HAVE IN MY 9 YRS OF FLYING BEEN THE MOST DIFFICULT TO ARM AND DISARM. YOU MUST USE 2 HANDS AND THE ARMING HANDLE IS VERY DIFFICULT TO PUSH BACK EVEN FOR MALE FLT ATTENDANTS AND PLTS.
