EASA AD CF-2024-08
Doors — Overwing Emergency Exit Door (OWEED) Escape Slide Mechanism — Rigging Pin Left Installed
Summary
Airworthiness Directive CF-2024-08 is issued by Transport Canada concerning the Overwing Emergency Exit Door (OWEED) escape slide mechanism on Airbus Canada Limited Partnership (ACLP) Model BD-500-1A10 and BD-500-1A11 aircraft. This directive addresses a safety issue involving rigging pins left installed in the escape slide mechanism that can prevent slide deployment. The directive applies to specific serial numbers of these aircraft models.
What Changed
CF-2024-08 introduces a mandatory inspection and removal requirement for rigging pins found installed in the left-hand and right-hand side OWEED escape slide mechanisms. This is a new regulation responding to findings that rigging pins from production may block slide deployment, posing a safety risk.
Why It Matters
This directive is critical for aviation professionals because it ensures the proper functioning of emergency evacuation slides, a key safety feature. Operators and maintenance organizations must verify and correct any installation errors to maintain airworthiness and compliance with Canadian Aviation Regulations. Failure to comply could result in unsafe conditions during emergency evacuations.
What To Do
Operators of affected ACLP BD-500-1A10 and BD-500-1A11 aircraft must inspect both left-hand and right-hand side OWEED escape slide mechanisms for rigging pins and remove any found before further flight. This action must be completed within 12 months from the effective date of 14 March 2024, following the instructions in ACLP Service Bulletin BD500-522004 Issue 001 or later approved revisions.
