FAA safety directive requires right-wing corrective actions for Bombardier BD-700-2A12 airplanes

**Buyer:** Federal Aviation Administration (FAA)
**Posted:** October 14, 2026
**Identifier:** 2026-21010
**NAICS:** 336413

The FAA issued a safety directive for certain Bombardier BD-700-2A12 airplanes, requiring corrective actions for right-wing component-clearance issues.
- **Government authority:** U.S. Department of Transportation, Federal Aviation Administration (FAA).
- **OEM:** **Bombardier, Inc.** manufactures the affected aircraft. The directive incorporates procedures from Transport Canada.
- **Affected aircraft:** 60 U.S.-registered Bombardier Model BD-700-2A12 airplanes are estimated to be affected; this is not a purchase quantity.
- **Required compliance work:** Replace the right-wing harness bracket clip-nut and fuel tube assemblies; inspect clearance between hydraulic system 3 lines and the fuel vent tube; and complete applicable follow-up work, including hydraulic system support bracket replacement if required. The actions address low clearance that could contribute to a fuel-tank ignition source during a lightning strike.
- **Cost estimates:** FAA estimates required actions at $2,693 per affected airplane and possible on-condition bracket replacement at $5,772 per affected airplane. These are estimated compliance costs, not a contract value.
- **Opportunity status:** This is a regulatory safety requirement, not a procurement solicitation or award.

### Description

The FAA issued a final airworthiness directive for certain Bombardier, Inc., Model BD-700-2A12 airplanes. It addresses reported low clearance conditions in the right wing involving fuel-line components, hydraulic system lines, and a fuel vent tube, which could result in an ignition source developing in the fuel tank in the event of a lightning strike. The directive requires rectifying specified clearance conditions, inspecting for adequate clearance, and completing applicable on-condition actions. It is effective November 18, 2026.
