## 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 missing or under torqued fasteners on the slat 2 cove rib 6 brackets. This proposed AD would require a general visual inspection (GVI) of affected fasteners on slat 2 cove rib 6 brackets to determine if all fasteners are installed and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
