An Air Canada Rouge Airbus A319-100, registration C-GBHY performing flight RV-1823 from Cancun (Mexico) to Toronto,ON (Canada) with 139 people on board, was enroute at FL370 when the crew received an "AIR ENG 2 BLEED ABNORM PR" message, the cabin temperature fluctuated and pack 2 showed intermittent faults. The crew was able to clear the fault, for further troubleshooting the crew reduced the mach number. Following power reduction the right hand engine (CFM56) no longer reacted to thrust commands and remained at about 50% N1 with significant airframe vibrations and decay in airspeed. The crew declared Mayday and descended the aircraft. Following the descent the crew was able to restore normal engine performance after working the engine stall checklist. The crew cancelled the emergency and continued to Toronto for a safe landing.
The Canadian TSB reported: "Following occurrence, the PRV (pressure regulating valve) was removed and replaced with a serviceable unit. Subsequent serviceability tests were conducted with satisfactory results. It is suspected that bleed configuration at high altitude induced the compressor stall event."
