This quick visual inspection helps keep flights safe and could mean fixing issues if found. Comments on this plan are open until June 15, 2026, so owners should act soon to avoid bigger problems or costs later. ## Abstract The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This proposed AD was prompted by reports of missing or under torqued fasteners on the slat 2 cove rib 6 brackets. This proposed AD would require a general visual inspection (GVI) of affected fasteners on slat 2 cove rib 6 brackets to determine if all fasteners are installed and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products. ## Effects PRIA read - Mandatory inspection of slat fasteners: cost, low. If you operate a Bombardier Model BD-700-2A12 airplane, the FAA proposes a required general visual inspection (GVI) of fasteners on the slat 2 cove rib 6 brackets. The required on-condition actions include torquing fasteners to 20–25 lbf·in., checking for damage (like deformation or cracking), repa… - Estimated inspection cost per airplane: cost, low. The FAA estimates the required inspection will take 5 work-hours at $85 per hour for a cost of $425 per airplane and that the rule would affect 36 U.S.-registered BD-700-2A12 airplanes for a total estimated cost to U.S. operators of $15,300. These are the FAA's estimated baseline compliance costs i… - Potential on-condition repair costs: cost, low. If on-condition actions are needed after the inspection, the FAA estimates those actions would cost about $269 per airplane (2 work-hours at $85/hour = $170 labor plus $99 parts). The FAA does not know how many airplanes will require these on-condition actions. - Immediate fixes required before flight: cost, medium. The proposed AD specifies that, where Transport Canada AD CF-2025-46 says 'If fasteners are installed' or 'If fasteners are missing,' this FAA AD changes those instructions to require the specified actions 'before further flight.' That means any required torquing, repairs, or installations must be… - Manufacturer warranty may reduce costs: benefit, low. The FAA notes the manufacturer may cover some or all of the costs of the required actions under warranty, which could reduce the financial impact on affected operators. ## Related documents - [2026-15585](https://policyrisk.com/federal-register/2026-15585): Requirements for Interference-Tolerant Radio Altimeter Systems, 2026-07-31 - [2026-13440](https://policyrisk.com/federal-register/2026-13440): Enabling Supersonic Overland Flight, 2026-07-02 - [2026-13126](https://policyrisk.com/federal-register/2026-13126): Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period, 2026-06-30 - [2026-08943](https://policyrisk.com/federal-register/2026-08943): Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility, 2026-05-06 - [2025-04846](https://policyrisk.com/federal-register/2025-04846): Extension of the Prohibition Against Certain Flights in the Territory and Airspace of Libya, 2025-03-20 - [2025-03853](https://policyrisk.com/federal-register/2025-03853): Enforcement Policy Regarding “Drug and Alcohol Testing of Certificated Repair Station Employees Located Outside of the United States; Corre…, 2025-03-11 ## Sources - [2026-08291 on federalregister.gov](https://www.federalregister.gov/documents/2026/04/29/2026-08291/airworthiness-directives-bombardier-inc-airplanes) - [2026-08291 as published (PDF)](https://www.govinfo.gov/content/pkg/FR-2026-04-29/pdf/2026-08291.pdf) ## Related - [Previous: 2026-08290, Airworthiness Directives; Airbus SAS Airplanes](https://policyrisk.com/federal-register/2026-08290) - [Next: 2026-08316, Airworthiness Directives; Leonardo S.p.a.
