Description

The FAA proposes a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes due to reports of fuel leakage near rib 6 during production pressure testing. An investigation found oversized holes in an outboard shear-tie, which could lead to crack formation and potential failure of shear-ties, risking structural integrity. The proposed AD requires inspection of fasteners and fastener holes at rib 6 for discrepancies and applicable on-condition actions such as repair and reinstalling fasteners. The FAA invites comments on this proposed AD by October 26, 2026.
