ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2002-14-28, which applied to all de Havilland Inc. (type certificate currently held by Viking Air Limited) Model DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes. AD 2002-14-28 established a life limit for the front fuselage struts and required repetitively replacing the front fuselage struts every 15 years or repetitively inspecting the struts for corrosion or fatigue damage and replacing when the damage exceeded a certain level. Since the FAA issued AD 2002-14-28, Transport Canada superseded its mandatory continuing airworthiness information (MCAI) to correct this unsafe condition on these products. This AD requires either doing recurring visual inspections, borescope inspections, and non-destructive inspections (NDIs) of the struts and airframe lugs with corrective action as necessary or replacing the struts every 15 years and doing recurring NDIs of the airframe lugs with corrective action as necessary. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective September 30, 2022. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of September 30, 2022.
