## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

FLIGHT NUMBER 483, UNDER THE CALL SIGN BLUESTREAK 483, A US AIRWAY EXPRESS FLIGHT, BEING OPERATED BY PSA AIRLINES, LANDED AS SCHEDULED AT THE CHATTANOOGA AIRPORT.  WHILE TAXIING TO THE GATE, THE CREW STARTED THE APU AND THEN OPENED THE APU LOAD VALVE TO ALLOW THE APU TO POWER THE AC PACKS, AND THEY THOUGHT THEY SMELLED SOMETHING BURNING.  THEY COULD NOT DETERMINE WHERE THE SMELL WAS FROM, SO THEY STOPPED JUST SHORT OF THE GATE, DECLARED AN EMERGENCY, AND PROCEEDED WITH AN EMERGENCY EGRESS.  ALL 48 PASSENGERS WERE EVACUATED SAFELY AND ROUTED INTO THE TERMINAL.  CONTRACT MX DID TROUBLESHOOTING AND DETERMINED THAT SEEPAGE OIL FROM THE APU WAS ABLE TO DRAIN INTO OR AROUND THE HOT BLEED AIR FROM THE APU LOAD VALVE AND CAUSE THE BURNING SMELL.  THE APU LOAD VALVE WAS DEACTIVATED, PER THE PSA MEL, AND THE AIRCRAFT WAS PUT BACK INTO SERVICE.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
