SW4, Dryden ON Canada, 2020

Summary

On 24 February 2020, the crew of a Fairchild SA-227 departing Dryden lost directional control and the aircraft veered off the side of the runway soon after beginning its takeoff roll with the subsequent impact with a frozen snow bank causing significant damage to the aircraft. The Investigation found that takeoff had been commenced with the right propeller still on the start locks after failure to follow two separate normal procedures during what was the very inexperienced First Officer’s first day of line training after joining the operator and obtaining a type rating.

Description

On 24 February 2020, a Fairchild SA-227-DC Metro 23 (C-GIVB) being operated by Perimeter Aviation on a scheduled domestic passenger flight marketed under the wholly-owned ‘Bearskin Airlines’ brand from Dryden to Sioux Lookout as BLS344 and being used for First Officer Line Training began its takeoff on runway 12 at Dryden in normal day visibility but almost immediately directional control was lost and the aircraft departed the side of the runway and hit a frozen snow bank. The aircraft sustained substantial impact damage and one of the six passengers was seriously injured when propeller blade debris penetrated the fuselage.
