Fuselage Structure — Inspection and replacement of fuselage struts
The Canadian Airworthiness Directive CF-2020-22 addresses inspection and replacement requirements for fuselage struts on Viking Air Ltd. DHC-2 Mk. I, Mk. II, and Mk. III aircraft. It mandates updated inspection procedures including visual, borescope, and non-destructive inspections to prevent structural failure caused by corrosion and damage to fuselage struts and airframe lugs. The directive also introduces improved strut part numbers with enhanced corrosion resistance.
