Aircraft Accident/Incident Report

Colorado Spring, Colorado 80916
Saturday, April 17, 2004 14:55 MDT

NTSB Narrative Summary Released at Completion of Accident

The captain said that while taxiing to the gate after landing, the flight attendant reported that there was smoke in the cabin. The captain said he called the flight attendant back to get more details. The flight attendant told him the cabin was full of smoke. The captain stopped the airplane, set the parking brake, and ordered the airplane evacuated. The passengers and crew evacuated the airplane. The flight attendant described the smoke as blue in color and smelling like burning oil. An examination of the airplane showed that a fan by-pass check valve in the right air conditioning pact failed causing the air conditioning pack to overheat.

NTSB Probable Cause Narrative

The failed air conditioning fan by-pass check valve and the subsequent overtemperature of the air conditioning pack.
