Notice of proposed rulemaking (NPRM).
Summary
The Federal Aviation Administration (FAA) is proposing a new safety rule for a specific group of Bombardier BD‑700‑2A12 aircraft. During routine production testing, some planes were found to leak fuel near a structural component called rib 6, caused by oversized holes in an outboard shear‑tie. To prevent possible fuel loss and the associated fire risk, the rule would require owners and operators to inspect the fasteners and their holes at rib 6 and take corrective actions if any problems are discovered. This proposed airworthiness directive (AD) is issued by the FAA, the transportation‑safety agency that oversees all civil aviation in the United States. It applies to every Bombardier BD‑700‑2A12 airplane that is currently in service or in the process of being delivered to U.S. operators. The notice was published on September 9, 2026, and the public comment period ends on October 26, 2026. After the comment deadline, the FAA will review the feedback, possibly revise the rule, and then issue a final AD that would make the inspection requirement mandatory, with a compliance timeline to be set in the final rule.

Official 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 fuel leakage near rib 6 during production pressure testing. An investigation found oversized holes in a certain outboard shear-tie. This proposed AD would require an inspection of the fasteners and fastener holes at rib 6 for discrepancies and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
