The FAA is moving to distribute all Airworthiness Directives (ADs) electronically.
In September 2007, the FAA stopped mailing paper copies of ADs and Special Airworthiness Information Bulletins (SAIBs) to owners and operators of transport aircraft. A schedule released Aug. 5 cuts mail delivery to operators of transport rotorcraft on Oct. 1 this year and all other rotorcraft operators on Jan. 1, 2010. Mailings will stop to general aviation owners and operators or aircraft, engines, and propellers on March 1, 2010.
After that, ADs and SAIBs can be obtained at the Regulatory and Guidance Library website (RGL.FAA.gov). You can sign up here for automatic e-mail service. The information also will be available at the Federal Register website (GPOAccess.gov/fr).
Don’t have access to a computer? After the changeover date, you can take out a paid subscription to a biweekly printed copy of ADs published the previous two weeks in the Federal Register. This will not contain SAIBs.
Emergency ADs will be mailed until further notice.
