QK7925 - Incident: Jazz CRJ9 at Toronto on Sep 15th 2020

A Jazz Canadair CRJ-705, registration C-FCJZ performing flight QK-7925 from Thunder Bay,ON to Toronto,ON (Canada) with 47 people on board, was on final approach to Toronto's runway 05 when the crew selected the flaps from 30 to 45 degrees and received a "FLAPS FAIL" caution, the flaps remained at 30 degrees. The crew initiated a go around, retracted the flaps without problems, the caution message disappeared. The crew decided to prepare for a landing in line with the abnormal checklists at flaps 1 (slats at 20 degrees). Due to shifting winds the runway was changed to 23. The aircraft landed on runway 23 without incident, emergency services followed the aircraft to the apron.

The Canadian TSB reported an inspection of flaps and slats found no fault. The Maintenance Diagnostics Computer (MDC) had also not logged any faults. The slat/flap lever was replaced and the system tested serviceable.
