NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

A FLIGHT ATTENDANT FELL FROM THE ACFT DURING OPENING OF THE L5 DOOR. THE F/A WAS HELPING A COMPANY GROUND PERSON, WHO WAS OUTSIDE ON THE BOARDING STEP. THE BOARDING STEP WAS NOT AGAINST THE ACFT BUT ABOUT 1 FT AWAY FROM IT. WHEN THE DOOR WAS OPENED, THE F/A FELL THRU THE OPEN DOORWAY AND TO THE GROUND ABOUT 20 FT BELOW. THE COMPANY PROCEDURE REQUIRES HAND SIGNAL COMMUNICATION BETWEEN PERSONNEL INSIDE AND OUTSIDE DURING DOOR OPENING. THE INVESTIGATION REVEALED THAT RADIO COMMUNICATIONS WERE BEING USED BETWEEN THE GROUND PERSONNEL AND A COMPANY REP. THE GROUND PERSON COULD NOT ACTIVATE THE DOOR AND REQUESTED THE COMPANY REP TO OPEN IT. THE DOOR STILL WOULD NOT OPEN. THE COMPANY REP REQUESTED HELP FROM THE NEARBY FLIGHT ATTENDANT. THE BOARDING STEPS WERE INITIALLY FULLY AGAINST THE AIRCRAFT BUT WERE PULLED AWAY WHEN THE DOOR WOULD NOT CLEAR THE HANDRAILS OF THE BOARDING STEP. THE AIRFRAME HAS A CURVATURE AT THE L5 DOOR LOCATION. THE BOARDING STEP IS SQUARE SHAPED.
