AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators must verify the installation of affected upper and side link assemblies within specified groups and replace any affected parts before reaching 8,500 flight cycles or 17,000 flight hours, whichever occurs first. Verification for Group 1 aircraft must be completed by 24 March 2026, with replacement actions following accordingly. Installation of affected parts is prohibited as of 24 March 2026.
Summary
Canadian Airworthiness Directive CF-2026-27 addresses the replacement of upper and side pylon link assemblies on Airbus Canada Limited Partnership model BD-500-1A11 and BD-500-1A10 aircraft. The directive targets assemblies potentially manufactured from incorrect titanium alloy material, which could compromise structural integrity. It mandates verification and replacement of affected parts to ensure continued airworthiness.
What changed
AD CF-2026-27 corrects typographical errors and compliance time issues found in the previous AD CF-2026-13. It clarifies that flight cycles and hours apply to the parts themselves and removes an inadvertent 90-day compliance time for certain inspections. The directive maintains the original replacement requirements while refining procedural details.
Why it matters
This directive is critical for operators and maintenance organizations to prevent premature structural damage or failure of pylon link assemblies caused by unsubstantiated titanium alloy material. Compliance ensures aircraft safety and regulatory adherence, avoiding potential grounding or operational restrictions. Accurate record-keeping and timely part replacement are essential for continued airworthiness.
