What to do
Operators must implement all applicable maintenance tasks and life-limited part replacements as specified in PSM 1-6-11 Revision 9 starting from the effective date of 2019-01-23. Specific phase-in allowances allow scheduling flexibility, such as replacing flight control pulleys within 12 months if in service over 48 months, and overhauling landing gear legs within 6 months if serial numbers are missing. Inspections for wing disbond must be completed within 120 days for aircraft over 20 years old. Later approved revisions of PSM 1-6-11 are acceptable for compliance.
Summary
Airworthiness Directive CF-2019-02 is issued by Transport Canada and applies to Viking Air Ltd. DHC-6 series 1, 100, 110, 200, 210, 300, 310, 320, and 400 aeroplanes. It mandates compliance with the airworthiness limitations specified in Viking Air Ltd.'s Airframe Airworthiness Limitations Manual, Product Support Manual 1-6-11 Revision 9, which includes updated maintenance tasks and life limits for various airframe components.
What changed
This directive replaces previous ADs CF-80-06, CF-81-07R4, and CF-95-12 by consolidating their requirements into the updated PSM 1-6-11 Revision 9. It introduces new mandatory tasks such as replacement of flight control pulleys, overhaul of main landing gear legs with serial number requirements, and inspections for wing skin disbond and nacelle longerons. Additionally, it changes compliance from ranges of flight hours and cycles to specific limits with phase-in allowances to facilitate scheduling.
Why it matters
Compliance with AD CF-2019-02 ensures continued airworthiness and safety of DHC-6 aircraft by enforcing updated maintenance standards and life limits. Operators and maintenance organizations must adapt to the new specific limits and additional inspection tasks to avoid unsafe conditions. The directive also streamlines compliance by consolidating multiple previous ADs, reducing regulatory complexity for maintenance planning and record keeping.
