## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Models EMB-500 and EMB-505 airplanes. This proposed AD was prompted by a report that the operational envelope does not contain airspeed limitations and procedures for operating the airplane at static air temperatures below -54 (deg)C. This proposed AD would require revising the airplane flight manual (AFM) to incorporate new and revised airspeed limitations and procedures. The FAA is proposing this AD to address the unsafe condition on these products.
