FAA AD Differences Note 3: This AD differs from the MCAI and/or service information as follows: Agência Nacional de Aviação Civil (ANAC) Brazilian Airworthiness Directive 2009-02-01, dated February 12, 2009, is applicable to “all EMB-145 and EMB-135 aircraft models in operation.” However, this does not agree with the service information specified in Table 2 of this AD, which specifies that only certain Model EMB-145 and EMB-135 airplanes are affected and identifies them by serial number. This AD is applicable only to the airplanes listed in the applicable service bulletins. This difference has been coordinated with the ANAC.
