A Canadian airworthiness directive requiring checks of specified Dash 8 spoiler-control brackets takes effect on October 28, 2026. Transport Canada issued CF-2026-51 on October 14 after reports of cracks occurring earlier in component life than previously reported.
Which aircraft and parts are covered?
The two-page directive lists DHC-8-102, -103, -106, -201, -202, -301, -311, -314 and -315 aircraft, serial numbers 003–672, with the specified bracket part numbers installed. It does not list the DHC-8-400/Q400.
Why the brackets matter
Transport Canada says a bracket separating from the wing could jam an aileron control cable and disable the associated spoiler. The resulting loss of control-surface function could lead to loss of aircraft control if uncorrected.
Inspection thresholds, rather than a blanket grounding
For brackets exceeding 20,000 flight hours or cycles at the effective date, the initial inspection is due within 2,000 hours or cycles, whichever comes first. Repeat inspections have a 2,000-hour/cycle maximum interval. Cracks or loose fasteners require the directive’s replacement actions. Improved brackets are still being designed as a future terminating action.
This report summarizes the regulator’s requirements. Operators need the complete applicability, component records and referenced service-bulletin procedures to determine compliance. The directive does not identify a cancelled passenger flight or establish that the aircraft pictured below has the affected parts.
For passengers, check the operating airline’s actual flight status and booking messages; an aircraft-family name alone does not establish a cancellation.
