A proposal is not in force. If adopted, it becomes an AD, usually with changes. Only the Federal Register edition is official.

Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-545 and EMB-550 airplanes. This proposed AD was prompted by the possibility of the Ram Air Turbine (RAT) compartment door seal peeling off and becoming entangled with the RAT rotor. This proposed AD would require replacement of the RAT compartment door seal. The FAA is proposing this AD to address the unsafe condition on these products.
