THE CABIN AND COCKPIT FILLED WITH SMOKE DURING CLIMBOUT. THE PILOT DECLARED AN EMERGENCY AND LANDED WITHOUT INCIDENT. HOWEVER, DURING THE TAXI TO THE RAMP THE FLIGHT CREW STARTED THE APU AND SMOKE FILLED THE CABIN AND COCKPIT AGAIN. THE PILOT STOPPED THE AIRPLANE AND ORDERED AN EVACUATION VIA THE EMERGENCY SLIDES. THE FLIGHT ATTENDANTS STARTED THE EVACUATION AND DISCOVERED THAT THREE SLIDES WOULD NOT DEPLOY. EXAMINATION OF THE AIRPLANE DISCLOSED THAT THE NUMBER 2 AIR CYCLE MACHINE HAD OVERHEATED AND SMOKE FLOWED INTO THE AIRPLANE. ADDITIONALLY, THE GIRT BARS ON THE 3 INOPERATIVE SLIDES WERE NOT INSTALLED IN ACCORDANCE WITH STANDARD PROCEDURES.
The National Transportation Safety Board determines the probable cause(s) of this incident to be: THE OVERHEATING OF THE NUMBER 2 AIR CYCLE MACHINE WHICH RESULTED IN AN EMERGENCY EVACUATION VIA SLIDES; THE FAILURE OF THE FLIGHT ATTENDANTS TO SECURE THE SLIDE GIRT BARS.
