## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of internal corrosion on the inboard flaps found prior to regularly scheduled maintenance checks. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate a certain aircraft maintenance manual (AMM) task. The FAA is proposing this AD to address the unsafe condition on these products.
