An Air Canada Rouge Airbus A319-100 has suffered a rapid loss of cabin pressure. The aircraft registered C-GARO and was performing flight RV-1692 from Calgary to Halifax with 132 people on board. The aircraft had just levelled off at cruise (FL350) when the crew initiated an emergency descent due to the loss of pressure in the cabin. They diverted to Saskatoon for a safe landing due to the safety risk of continuing.
The Canadian TSB reported the passenger oxygen masks were not released. As a result, the right-hand engine (CFM56) bleed air pressurization regulator valve was replaced by maintenance after the incident.
