## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by tail strikes that occurred during landing with partial flap configurations. This proposed AD would require revising the existing airplane flight manual (AFM) to provide the flightcrew with procedures to follow when landing under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
