EASA AD CF-2025-41
Equipment/Furnishings — Seats — Missing Loctite
Summary
Canadian Airworthiness Directive CF-2025-41 addresses a safety issue involving missing Loctite on seat frame assemblies in Bombardier BD-700-1A10, BD-700-1A11, and BD-700-2A12 aircraft. The directive mandates corrective actions to ensure structural integrity of seat belt anchor points and backrest locking mechanisms. This AD applies to specific serial numbers of these Bombardier models.
What Changed
CF-2025-41 introduces a mandatory requirement to apply Loctite on non-locking fastener joints of seat frame assemblies as per Bombardier Service Bulletins dated 19 December 2023. Previously, the corrective action was managed through monitored fleet campaigns without an AD, but this directive makes compliance compulsory to address the unsafe condition.
Why It Matters
This directive is critical for maintaining the safety and structural integrity of seat restraint systems, which protect occupants during flight. Operators and maintenance organizations must ensure compliance to prevent potential failure of seat belt anchor points and backrest locks, which could compromise occupant safety. The AD ensures uniform corrective action across the affected fleet.
What To Do
Operators of affected Bombardier BD-700-1A10, BD-700-1A11, and BD-700-2A12 aircraft must apply Loctite to specified non-locking fastener joints following the applicable Bombardier Service Bulletins within 10 months from 3 September 2025. Compliance must be documented and verified to meet Canadian Aviation Regulation requirements.
