Incident: Air Canada A320 near Vancouver on Nov 26th 2011, acrid smell on board
An Air Canada Airbus A320-200, registration C-FTJP performing flight AC-162 (scheduled dep Nov 25th) from Vancouver,BC to Toronto,ON (Canada) with 152 people on board, was climbing through 10,000 feet out of Vancouver when the crew reported an acrid smell in the cabin and returned to Vancouver declaring urgency with ATC due to overweight landing and possibly hot brakes. The aircraft landed safely in Vancouver about 15 minutes later.
A replacement Airbus A320-200 reached Toronto with a delay of 2.5 hours.
The Canadian TSB reported the source of the odour is believed to be the auxiliary power unit's (APU) bleed. Maintenance conducted an engine run with the APU off, the smell dissipated. The APU bleed valve was deactivated according to minimum equipment list requirements, an overweight landing inspection could be skipped because touchdown occurred at less than 360 fpm and the aircraft returned to service without further incident.
