Quick Answer
What does FAA AD 2026-15-09 require for BD-700 operators?
FAA AD 2026-15-09 Bombardier: effective September 3, 2026, requires operators of certain Bombardier BD-700-1A10 and BD-700-1A11 aircraft to inspect for affected brake control units and replace them if found. Affected BCU part numbers are prohibited from installation. The AD follows a main landing gear tire burst caused by an affected BCU.

What Changed
The FAA published AD 2026-15-09 on July 30, 2026. It is effective September 3, 2026.
The AD adopts Transport Canada AD CF-2022-53, dated September 8, 2022. The Transport Canada source AD was issued nearly four years ago. The FAA’s adoption follows the standard bilateral process, but the timeline is notable — operators on the Canadian register have been subject to this requirement since late 2022.
The triggering event was an in-service main landing gear tire burst upon landing. Investigation identified the cause as a defective brake control unit.
Why It Matters
A main landing gear tire burst on landing is a serious safety event. Tire debris can damage the landing gear structure, hydraulic lines, wheel well, and lower fuselage. On a BD-700 — a large-cabin business jet with high approach speeds — a tire burst also affects directional control during the landing roll.
The root cause is the brake control unit itself. An affected BCU can command abnormal brake pressure during the landing sequence, causing the tire to fail.
The AD requires identification and replacement of affected BCUs. Once replaced, the unsafe condition is resolved for that aircraft. The AD also prohibits installation of affected BCU part numbers going forward — preventing the issue from recurring through spares inventory.
BD-700 Family — Six Items in 2026
This AD adds to the sixth BD-700 family compliance item that ARW is tracking in 2026.
| # | Authority | AD | Models | System | Status |
|---|---|---|---|---|---|
| 1 | FAA | 2026-11-07 | -1A10, -1A11, -2A12 | Seat frame Loctite | Effective July 20 |
| 2 | FAA | 2026-09-18 | -1A10, -1A11 | Baggage door bolt torque | Effective June 26 |
| 3 | FAA | 2026-14-01 | -2A12 | Slat 2 cove rib fasteners | Effective August 14 |
| 4 | TC | CF-2026-17 | -2A12 | Incomplete fleet campaigns | Effective May 6 |
| 5 | TC | CASA-2026-02 | -2A12 | Fuel-feed line clearance | Advisory |
| 6 | FAA | 2026-15-09 | -1A10, -1A11 | Brake control unit | September 3 |
Plus the SPDA NPRM and TC wing structure safety alert also tracked in the ARW compliance tracker.
For operators managing mixed BD-700 fleets — Global Express, Global 5000, Global 6000, and Global 7500 — the consolidated picture now requires tracking compliance across multiple models, multiple ADs, and multiple regulatory authorities simultaneously.
Who Is Affected
This AD applies to certain BD-700-1A10 and BD-700-1A11 airplanes as identified in Transport Canada AD CF-2022-53.
| Model | Aircraft Type |
|---|---|
| BD-700-1A10 | Global Express, Global 5000 |
| BD-700-1A11 | Global 6000 |
The BD-700-2A12 (Global 7500) is not included in this AD.
Not all -1A10 and -1A11 aircraft are necessarily affected. Applicability is determined by serial number, as defined in Transport Canada AD CF-2022-53. Check your specific aircraft against the TC AD.
Required Action
Step 1 — Inspect for affected BCU.
Determine whether an affected brake control unit is installed on your aircraft, using the identification criteria in Transport Canada AD CF-2022-53.
Step 2 — Replace if found.
If an affected BCU is installed, replace it with a serviceable unit that is not subject to the AD before further flight.
Step 3 — Installation prohibition.
Do not install affected BCU part numbers on any applicable BD-700-1A10 or BD-700-1A11 airplane. Affected parts must be removed from shelf stock and quarantined.
Operational Impact
The BCU inspection and replacement are landing gear system tasks. Access to the BCU requires maintenance access to the brake system — this can typically be accomplished during a scheduled maintenance visit, but may require unscheduled downtime if an affected unit is found and a replacement is not immediately available.
Spare parts availability is the main risk. The AD prohibits installation of affected part numbers, meaning only non-affected BCUs are eligible for installation. Confirm the availability of the replacement BCU with Bombardier or your parts supplier before scheduling the inspection.
For operators with Canadian-registered BD-700 aircraft: Transport Canada AD CF-2022-53 has been in effect since September 2022. Confirm compliance status against the TC AD. If already compliant under the TC AD, no additional action is required under the FAA AD for those aircraft.

FAQ
Does this AD apply to the Global 7500 (BD-700-2A12)?
No. This AD applies only to the BD-700-1A10 (Global Express/Global 5000) and BD-700-1A11 (Global 6000). The Global 7500 is not in scope.
My aircraft is Canadian-registered and already complies with TC AD CF-2022-53. Do I need to do anything under this FAA AD?
If your aircraft is not on the US register, the FAA AD does not apply. Your compliance obligation is under the Transport Canada AD. If your aircraft is on the US register and you have already completed the actions specified in TC AD CF-2022-53, confirm compliance documentation aligns with the FAA AD’s requirements.
What caused the tire burst?
An affected brake control unit commanded abnormal brake pressure during the landing sequence, causing the main landing gear tire to fail.
Can I install a replacement BCU from my spare stock?
Only if the replacement BCU is not an affected part number as defined in TC AD CF-2022-53. Affected BCUs must be removed from shelf stock and quarantined. Installing an affected BCU after the effective date would constitute a violation of the AD.
How many BD-700 compliance items are there in 2026?
This is the sixth BD-700 family item tracked by ARW in 2026, covering ADs from both the FAA and Transport Canada across the -1A10, -1A11, and -2A12 models.
