What to do
Affected operators must inspect and adjust tie-rod assemblies according to Airbus Canada Service Bulletin BD500-252038 within specified air time limits: 4900 hours for aft cabin galleys, lavatories, and certain forward cabin areas, and 9350 hours for forward cabin galleys and right forward cabin stowage. Compliance must be completed by these deadlines unless already accomplished. Contact Transport Canada for alternative means of compliance if necessary.
Summary
The Airworthiness Directive CF-2021-25 issued by Transport Canada addresses tie-rod preload issues on interior monuments in Airbus Canada Limited Partnership aircraft models BD-500-1A10 and BD-500-1A11. The directive mandates inspection and adjustment of tie-rod assemblies in specific cabin areas to prevent potential hazards during emergency landings. This directive applies to aircraft with serial numbers 50010 through 50040 for BD-500-1A10 and 55003 through 55057 for BD-500-1A11.
What changed
CF-2021-25 introduces a new requirement to inspect and adjust tie-rod assemblies on interior monuments that may have been overtightened during production. It specifies compliance times for different cabin locations and mandates following Airbus Canada Service Bulletin BD500-252038 Issue No. 001 or later approved revisions. This is a new regulation addressing a previously unidentified risk related to monument installation.
Why it matters
This directive is critical for aviation professionals because overtightened tie-rods can induce unwanted stress, potentially causing monuments to become unconstrained during emergency landings. Such failures could block exits and injure occupants, posing serious safety risks. Operators, maintenance organizations, and compliance teams must ensure timely inspections and adjustments to maintain aircraft safety and regulatory compliance.
