FAA AD 2026-14-01: Bombardier BD-700-2A12 (Global 7500) Slat Cove Rib Fasteners — Third BD-700 AD This Year

Quick Answers

What does FAA AD 2026-14-01 require for Bombardier Global 7500 operators?

FAA AD 2026-14-01, effective August 14, 2026, requires a general visual inspection of fasteners on slat 2 cove rib 6 brackets on certain Bombardier BD-700-2A12 (Global 7500) aircraft. Reports of missing or under-torqued fasteners at this location prompted the AD. On-condition corrective actions are required before further flight if found.

Is the Global 7500 slat fastener AD the same as the BD-700 seat frame AD?

No. AD 2026-14-01 covers slat 2 cove rib 6 bracket fasteners on the BD-700-2A12 (Global 7500) only. The seat frame AD (2026-11-07) covers Loctite omissions on the BD-700-1A10, -1A11, and -2A12. The baggage door AD (2026-09-18) covers torque issues on the -1A10 and -1A11. All three are separate directives.

What Changed

The FAA published AD 2026-14-01 on July 10, 2026. It is effective August 14, 2026.

This AD adopts Transport Canada AD CF-2025-46, dated September 2, 2025, as its basis — a standard bilateral adoption under the FAA–Transport Canada agreement.

Reports identified missing or under-torqued fasteners on the slat 2 cove rib 6 brackets on certain Global 7500 aircraft. The issue relates to the manufacturing or maintenance process — fasteners either not installed or not torqued to the required specification.

Why It Matters

The slat 2, cove rib 6, and brackets are structural components in the wing leading-edge assembly. The fasteners connecting those brackets carry load as part of the wing’s structural redundancy system.

Missing or under-torqued fasteners reduce load-carrying capability at that location. That reduces the structural redundancy built into the wing design.

The consequence, if not detected and corrected, is that the remaining structure must carry loads for which it was not designed, potentially reducing safety margins in adverse conditions.

This is a structural integrity issue — not a cosmetic or avionics concern. It requires inspection before further flight beyond the compliance date.

BD-700 Series — Three ADs in 2026

This AD completes a trilogy of BD-700 airworthiness directives published by the FAA in 2026.

If you manage a Global 7500 fleet, confirm compliance status on all three ADs. They cover different systems, different variants, and different compliance dates. Compliance with one does not satisfy the others.

Who Is Affected

The AD applies to certain Bombardier BD-700-2A12 airplanes, as identified in Transport Canada AD CF-2025-46.

The BD-700-2A12 is the Global 7500 — Bombardier’s flagship ultra-long-range large-cabin business jet.

Not all Global 7500 aircraft are necessarily affected. Applicability is limited to specific serial numbers identified in the Transport Canada source AD. Confirm serial number scope against Transport Canada AD CF-2025-46 before planning inspection work.

Required Action

Perform a general visual inspection (GVI) of the affected fasteners on the slat 2 cove rib 6 brackets to determine whether all fasteners are installed and correctly torqued.

If fasteners are found missing or under-torqued: complete on-condition corrective actions before further flight.

The specific inspection method, compliance threshold, and on-condition procedures are defined in the service information referenced in the AD. Obtain the applicable Bombardier service document through your authorized Bombardier service representative.

Operational Impact

The GVI itself is a relatively non-invasive inspection task. Access to the slat 2 cove rib 6 area is required. Depending on the aircraft’s current maintenance schedule, this can likely be accomplished during a scheduled maintenance visit before August 14, 2026.

On-condition corrective actions — if fasteners are found missing or under-torqued — will require repair before further flight. Plan accordingly if the initial inspection is scheduled close to the compliance deadline.

Global 7500 operators with high-utilization aircraft should identify their next scheduled maintenance window now and confirm it falls before August 14, 2026.

FAQ

Is this the same AD as the BD-700 seat frame directive (2026-11-07)?

No. AD 2026-14-01 covers slat 2 cove rib 6 bracket fasteners on the Global 7500 (BD-700-2A12) only. AD 2026-11-07 covers seat frame Loctite omissions on the BD-700-1A10, -1A11, and -2A12. They are separate ADs covering different systems and different aircraft variants.

Does this AD apply to the BD-700-1A10 or BD-700-1A11?

No. AD 2026-14-01 applies only to the BD-700-2A12 (Global 7500). The -1A10 and -1A11 are not in scope.

How do I confirm which serial numbers are affected?

Applicability is defined in Transport Canada AD CF-2025-46, dated September 2, 2025. Check the document directly, or confirm with your Bombardier-authorized service representative.

What is a general visual inspection (GVI)?

A GVI is a visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. For this AD, it means checking that all fasteners on the slat 2 cove rib 6 brackets are present and appear correctly installed.

What if fasteners are found missing or under-torqued?

On-condition corrective actions must be completed before further flight. The specific repair procedure is defined in the Bombardier service documentation referenced in the AD.
