Incident at Brandon 30 NM W, Manitoba


1997-03-27: The Air Canada DC9 was in cruising flight at FL330, 30 miles west of Brandon, Manitoba, when the cabin altitude began to climb uncontrollably. The flight crew completed the emergency checklist and initiated an emergency descent to 10000 feet. As the flight was descending through 14000 feet the oxygen masks deployed. The flight was levelled at 10000 feet and climbed to 14000 feet because of the weather. Both air conditioning packs appeared normal with no flow, transfer lockout or standby lights illuminated. The remainder of the flight to Winnipeg was conducted at 14000 feet. Winnipeg maintenance replaced the #1 and #2 pressure controllers and the cabin pressure selector. The oxygen masks were repacked and the system was leak checked.
