Détails:AirTran flight 956 departed Atlanta at 15:41. At 1543:10, as the airplane was climbing through about 3800 feet, the flight crew observed numerous circuit breakers trip and several annunciator panel lights illuminate. The first officer than radioed a request to level off at 4000 feet and stated that they wanted to return to the airport. About 15:50, the airplane landed on runway 26R. After the landing, during the airplane's exit from the runway onto taxiway B-3, one of the flight attendants reported to the flight crew that smoke could be seen emanating from the left sidewall in the forward cabin; air traffic control personnel also notified the flight crew that smoke was coming from the airplane. The flight crew then initiated an emergency evacuation on one of the taxiways. Airport rescue and firefighting personnel assisted in subduing the fire.
Probable Cause:
PROBABLE CAUSE: "The leakage of lavatory fluid from the airplane's forward lavatory onto electrical connectors, which caused shorting that led to a fire. Contributing to the accident were the inadequate servicing of the lavatory and the failure of maintenance to ensure reinstallation of the shield over the fuselage station 237 disconnect panel."
