What to do
Operators of BD-500-1A11 aircraft must identify all existing repairs and damage assessments on affected structures within 48 months of the directive's effective date and request disposition from Airbus Canada Limited Partnership. If any repair or damage assessment falls outside authorized limits, corrective instructions must be implemented within specified compliance times. Additionally, no repair instructions issued before January 1, 2023, may be used for new repairs on the affected structures.
Summary
The Canadian Airworthiness Directive CF-2023-70 titled 'Standard Practices/Structures — Verification of Aircraft Repairs and Damage Assessments' applies to Airbus Canada Limited Partnership BD-500-1A11 model aircraft. It mandates a review and disposition of existing structural repairs and damage assessments based on revised operational load data affecting the A220 aircraft. The directive also prohibits the use of certain previously authorized repair data for new structural repairs.
What changed
This directive introduces mandatory corrective actions for BD-500-1A11 aircraft to reassess all existing structural repairs and damage evaluations in line with updated load limits. It disables the use of repair instructions issued before January 1, 2023, as a basis for new repairs on affected structures. It builds upon previous directives by extending corrective measures specifically to the BD-500-1A11 model.
Why it matters
This directive ensures that structural repairs and damage assessments on affected A220 aircraft maintain compliance with revised safety margins, preventing potential structural integrity issues. Operators, maintenance organizations, and compliance teams must verify that repairs meet updated standards to avoid unsafe conditions. It impacts maintenance planning and repair approval processes for the BD-500-1A11 fleet.
