Read the full NTSB narrative

SMOKE DETECTED IN THE CABIN RESULTED IN AN EVACUATION OF THE AIRCRAFT JUST AFTER BEING PUSHED BACK FROM THE JET-WAY. SUBSEQUENT INVESTIGATION ESTABLISHED THAT A MALFUNCTIONING PACK VALVE HAD CAUSED THE AIR-CONDITIONING SYSTEM TO OVERHEAT CAUSING THE SMOKE. THE EMERGENCY SLIDE AT DOOR 2R INFLATED PARTIALLY INSIDE THE ACFT AND WAS NOT USABLE. AT THE TIME OF INITIAL INVESTIGATION THE SLIDE TRAY DOOR FROM 2R WAS FOUND LYING ON THE FLOOR INSIDE THE ACFT. EXITS 1L, 2L, 4L, 4R AND FOUR OVER WING EXITS WERE USED (THE CAPT HAD LOWERED THE FLAPS TO FULL DOWN FOR THE EVACUATION). IT WAS DETERMINED DURING INVESTIGATION THAT THE DOOR WAS NOT OPENED FULLY ENOUGH FOR EXIT 2R TO OPERATE PROPERLY. UAL MODIFIED THE TRAINING TO EMPHASIZE THE DOOR OPENING PROCEDURE. THE FA SAID SHE PULLED THE (MANUAL INFLATION) HANDLE ON 2R.
