What to do
Affected operators must remove the affected bonding jumper and install a new one at a different location within 15 months from the effective date of 2026-09-08. They must follow the instructions in the applicable De Havilland Aircraft of Canada Limited Alert Service Bulletins. Operators of CL-415 variant aircraft who have already complied with specified Viking Air Ltd. service bulletins before the effective date meet the requirements of this AD.
Summary
Airworthiness Directive CF-2026-42 is issued by Transport Canada concerning De Havilland Aircraft of Canada Limited CL-215-6B11 (CL-215T variant) and CL-215-6B11 (CL-415 variant) aeroplanes. The directive addresses interference caused by a bonding jumper with the elevator trim-feel assembly, which may restrict elevator control movement. This AD mandates corrective action to prevent potential loss of elevator control during critical flight phases.
What changed
This new Airworthiness Directive introduces a requirement to remove the existing bonding jumper interfering with the elevator controls and install a new bonding jumper at a different location. It applies to all serial numbers of the CL-215T variant except 1082, 1083, 1089, and 1090, and all serial numbers of the CL-415 variant. The directive also recognizes prior compliance with certain Viking Air Ltd. service bulletins as satisfying the corrective action for the CL-415 variant.
Why it matters
This directive is critical for aviation professionals because interference with elevator controls can limit full elevator surface movement, potentially reducing aircraft control during crucial flight stages. Operators and maintenance organizations must ensure compliance to maintain airworthiness and flight safety. Compliance teams need to track and verify corrective actions to meet regulatory requirements and avoid grounding or operational restrictions.
