## Probable cause

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.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, climb - to cruise
  - air cond/heating/pressurization - overtemperature (cause)
- Airframe/component/system failure/malfunction, standing - engine(s) not operating
  - misc eqpt/furnishings,slides - not secured
  - miscellaneous equipment - not performed, flight attendant (cause)

## Analysis

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.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Incident 19920602021499I](https://openairdocs.org/incident/19920602021499I), Jun 2, 1992: Lkheed 10113851, Atlanta, GA. Smoke in cabin on climb. Returned. Landed safely. Evacuation. Some slides did not deploy. Air cycle machine faulty.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
