NTSB narrative
THE B767 WAS ON THE TAKEOFF ROLL. THE PRESSURE REGULATOR AND SHUTOFF VALVE COUPLED WITH THE HIGH PRESURE SHUTOFF VALVE MALFUNCTIONED RESULTING IN PRESSURES BEING DEVELOPED IN THE DOWNSTREAM AIRCRAFT DUCTING IN EXCESS OF 300 PSIG. A COUPLING IN THE AIR CONDITIONING PACK BAY SEPARATED ALLOWING THE DUCTING TO COME APART DUE TO THE EXCESS PRESSURE WITH SUFFICIENT FORCE TO TEAR LOOSE DUCT SUPPORTS, CRACK FAIRING PANELS, SEVER BOTH RH ENGINE THROTTLE CABLES, BREAK ACTUATING LINKAGE FOR THE LEADING EDGE SLAT DRIVE, BLOW OPEN RH PACK BAY DOOR AND CAUSE A SECTION OF DUCTING CONTAINING THE CENTER ISOLATION VALVE TO DEPART FROM THE AIRCRAFT. MINOR DAMAGE OCCURRIED TO THE AIR CRAFT STRUCTURE

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
