The FAA is cutting back mailing ADs and will no longer mail Special Airworthiness Information Bulletins to affected owners and operators. The agency will no longer mail AD corrections that don’t receive a new amendment number and AD number. The
FAA will mail ADs applicable to a certain engine model only to the owners and operators who have registered their engine, not to the registered aircraft owners and operators referenced in the AD. Mailed ADs will no longer include the preamble information.
