The Federal Aviation Administration has ordered critical modifications to the seat frames of Bombardier business jets to prevent potential failures in passenger restraint systems.
The agency released the airworthiness directive AD 2026-11-07 on June 15, 2026. This rule targets specific models including the BD-700-1A10, BD-700-1A11, and BD-700-2A12 variants.
The issue originates from seat frame assemblies completed without the proper application of Loctite on non-locking fastener joints. This deficiency directly impacts the lap belt anchors and backrest locking functions.
To resolve the unsafe condition, maintenance personnel must apply Loctite and replace the screws and hardware with new components. The FAA estimates this process will require 34 work-hours per airplane.
Compliance becomes mandatory on July 20, 2026. The directive covers 42 airplanes currently listed on the U.S. registry.
Per aircraft costs are projected at $3,024 when including both labor and materials. The total financial impact on domestic operators could reach $127,008.
This FAA rule corresponds to an earlier Transport Canada directive numbered CF-2025-41. The U.S. Department of Transportation made the complete document available through official channels.
Security professionals responsible for aviation assets should ensure that fleet managers prioritize these modifications. Proper execution of the directive will safeguard restraint system reliability across operations.
The publication appeared in the Federal Register, providing detailed instructions for affected parties. Operators are advised to consult the full text for precise applicability criteria and procedures.
The models involved represent advanced long-range business jets commonly used in executive and government transport. Ensuring their seat assemblies meet safety standards remains essential for all missions.
Failure to address the fastener joints could result in compromised passenger security during turbulence or unexpected maneuvers. The FAA acted to mitigate this risk proactively.
Parts and materials for the modification are specified in the directive to guarantee compatibility with existing seat structures. Technicians must follow exact procedures outlined by the manufacturer and regulators.
