What to do
Operators of Viking Air Limited CL-215-6B11 (CL-215 and CL-415 variants) must perform initial visual inspections of the aileron and flap interconnect system cables within 50 hours air time from October 26, 2018, and repeat these inspections every 50 hours until the Teflon™ parts are replaced. The replacement of the affected Teflon™ parts must be completed within 29 months from the effective date, following the specified Bombardier Service Bulletins.
Summary
Canadian Airworthiness Directive CF-2018-27 addresses excess fiberglass content in Teflon™ parts used in the aileron control system and flap interconnect system of Viking Air Limited CL-215-6B11 (CL-215 and CL-415 variants) aircraft. The directive mandates inspections and replacement of affected Teflon™ components to prevent potential cable wear and rupture. This AD applies specifically to certain serial numbers of these aircraft models.
What changed
This new Airworthiness Directive introduces mandatory visual inspections of the aileron control and flap interconnect system cables within 50 hours air time and requires repeated inspections every 50 hours until the affected Teflon™ parts are replaced. It also mandates the replacement of Teflon™ parts containing 15% fiberglass with parts meeting the required 5% fiberglass content within 29 months from the effective date.
Why it matters
This directive is critical for aviation professionals to prevent control cable damage or failure caused by excessive friction from improperly manufactured Teflon™ parts. Operators and maintenance teams must ensure compliance to maintain aircraft safety and airworthiness, avoiding potential in-flight control issues. Timely inspections and part replacements reduce risk and ensure regulatory compliance.
