The FAA last month made good on a longstanding promise to provide Airworthiness Directives (AD) and Special Airworthiness Information Bulletins (SAIB) only via e-mail. According to the agency, operators can sign up at the designated Web site (http://rgl.faa.gov) and receive the service by aircraft, as was the case with paper copies. Those who had previously signed up to receive ADs and SAIBs will have to do so again, however, as the new system will not automatically transfer existing subscriptions.
