An Expressjet Canadair CRJ-900, registration N138EV performing flight EV-5545/DL-5545 from Montreal,QC (Canada) to Atlanta,GA (USA) with 73 passengers and 4 crew, was accelerating for takeoff from Montreal’s runway 06R when the crew received an aft lavatory smoke indication and rejected takeoff at high speed. The aircraft slowed safely, vacated the runway and stopped, emergency services responded, the occupants evacuated through the main door.
The Canadian TSB reported the crew rejected takeoff at 150 KIAS. After the aircraft came to a stop the flight crew consulted with the cabin crew, who reported an odour from the lavatory. Although no fire was detected and the fire extinguisher did not need to be used, the occupants were evacuated through the main cabin door. Maintenance subsequently identified the aft lavatory fan was at fault.
