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:

(1) Add two reinforcements to the forward fuselage skin on the LH and RH sides between frames 9 to 10 and 10 to 11, and stringers 12 to 15. Install supports to the reinforcements and stringers as well as new fasteners to the reinforcements and supports, and reroute the electrical wiring on the affected area. Do all actions in accordance with EMBRAER Service Bulletin 145-53-0067, Revision 01, dated February 27, 2007; or Revision 02, dated August 28, 2007.
