We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done: Within 270 calendar days after the effective date of this AD, do a detailed inspection with the aid of a borescope for possible absence of the cable guard pins in the aileron control system inside the wings, in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145LEG-27-0023, dated January 24, 2006.
(1) If any cable guard pin having part number (P/N) NAS427K8, NAS427K28, or NAS427K36 is missing in the internal part of the left and right halfwing spar boxes, before further flight, install a new one bearing the same part number, in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145LEG-27-0023, dated January 24, 2006.
(2) If any cable guard pin P/N NAS427K26 is missing in the aileron control cable pulleys in the internal part of the wing leading edge III, before further flight, remove the corresponding leading edge and install a new cable guard pin bearing the same part number, in accordance with the Accomplishment Instructions of EMBRAER Service Bulletin 145LEG-27-0023, dated January 24, 2006.
Note: This AD differs from the MCAI and/or service information as follows:
The MCAI includes airplanes in addition to those specified in the applicability of this AD. Those airplanes are not included in this AD because they are modified by Supplemental Type Certificates (STCs) that are not FAA-approved. This AD includes only the U.S. certified airplanes identified in the referenced service information.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
