A Nolinor Aviation Boeing 737-800, registration C-FHNM performing flight
N5-821 from Varadero (Cuba) to Toronto,ON (Canada) with 166 people on board, was on approach to Toronto's runway 24L when the crew selected the gear down followed by a flaps extension to 15 degrees, however, no flags movement was indicated. The crew recycled the flaps lever, however, again no flaps movement was indicated. The crew initiated a go around, extended the flaps to 15 degrees using the alternate flaps extension and declared PAN PAN. The aircraft landed on runway 23 at a higher than normal landing speed.
The Canadian TSB reported emergency services were on standby and inspected the aircraft for hot brakes and possible leaks. Maintenance subsequently found a malfunction of the Flap Slat Electronic Sensor (FSEU) was at fault. A BITE check revealed no further faults and the aircraft was returned to service.
