The FAA has issued a new Airworthiness Directive (AD 2026-07-04) effective May 11, 2026 for certain Airbus Canada BD-500-1A10 and BD-500-1A11 airplanes. The directive addresses a manufacturing issue where tie rods supporting overhead stowage compartments may have insufficient thread engagement of the turnbuckle. This condition could cause the compartments to detach during an emergency landing, potentially injuring passengers and blocking emergency exits. The AD requires a one-time inspection of the tie rods for proper thread engagement and adjustment if inadequate engagement is found. It affects 80 U.S.-registered aircraft with an estimated compliance cost of $1,020 per airplane (12 work-hours at $85/hour).
