Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The mechanic in charge of taxiing the Boeing 727 allowed an unauthorized avionics technician to occupy the pilot seat. They inadvertently deactivated the brake pressurization system and struck a passenger jetway at the terminal gate. An ensuing fire destroyed the airplane and a company ground vehicle and extensively damaged the jetway. The terminal gate was also damaged. A total of 11 persons were injured.
