## Summary

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.
