## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by a report that corrosion was found on the shock strut cylinders during unscheduled maintenance of the nose landing gear (NLG). This proposed AD would require a modification of the NLG shock strut cylinder. The FAA is proposing this AD to address the unsafe condition on these products.
