Air Canada Jazz Flight 8954: Loss of Cabin Pressurization

Incident Overview and Immediate Response On a scheduled flight from Toronto, Ontario, to Fredericton, New Brunswick, an Air Canada Jazz Canadair CL600-2B19 (registration C-FSJJ, serial number 7058) operating as flight JZA8954 encountered a cabin altitude climb of approximately 1,000 feet per minute while cruising at flight level 330. The crew requested a descent to flight level 250 from Moncton Area Control Centre. After leveling off, the cabin altitude continued to rise, prompting a further descent to 9,000 feet. The pilots donned oxygen masks as the cabin altitude passed 10,000 feet, and passenger oxygen masks deployed automatically at 14,000 feet. The aircraft landed at Fredericton at 2115 UTC without further incident, and there were no injuries among the 50 passengers and 3 crew members.
