Air Canada Rouge flight AC1823 was in cruise at FL370, when the flight crew received an ECAM alert indicating AIR ENG 2 BLEED ABNORM PR, accompanied by fluctuating cabin temperatures and intermittent PACK 2 faults. Initial troubleshooting cleared the alert. To further assess the issue, the crew reduced the aircraft's Mach number. Following the power reduction, engine 2 failed to respond to subsequent thrust commands, remaining limited to approximately 50% N1. This was accompanied by significant airframe vibrations and a decay in airspeed. A Mayday was declared, and during the descent, the crew was able to restore normal engine performance by executing the compressor stall procedure for engine 2. The emergency was cancelled and the flight continued to CYYZ where it landed without further incident. Following occurrence, the PRV 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.
