Factual narrative
AMERICAN FLIGHT 323 (AA323) TAXIED TO THE HOLD SHORT LINE FOR RUNWAY 23R. IN AN ATTEMPT TO CORRECT A STATIC/PRESSURIZATION SYSTEM PROBLEM THE CREW PERFORMED A POWER RUN-UP. THE JET BLAST CONTACTED AND MOVED A NORTHWEST DC9 (NW878) WHICH WAS PARKED AT GATE A7, BEHIND AND PERPENDICULAR TO AA323. THE MOVEMENT OF THE AIRPLANE RESULTED IN AN EXTERNAL HEATER HOSE DISCONNECTING FROM THE AIRPLANE. A 15 LB METAL COUPLING ON THE END OF THE HOSE STRUCK A MECHANIC WHEN IT DISCONNECTED. THE MECHANIC WAS HOSPITALIZED WITH INTERNAL INJURIES. THE CREW OF AA323 REPORTED BEING UNAWARE OF THE CLOSE PROXIMITY OF NW878. AA323 DID NOT REQUEST OR OBTAIN A CLEARANCE TO PERFORM THE RUN-UP IN THE UNAUTHORIZED AREA. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
