Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and - 145EP Airplanes

The FAA is superseding an existing airworthiness directive (AD), which applies to all EMBRAER Model EMB-145, -145ER, -145MR, - 145LR, -145XR, -145MP, and -145EP airplanes. That AD currently requires repetitive inspections to detect cracking or failure of the rod ends of the aileron power control actuator (PCA), and corrective actions if necessary. This new AD requires the same repetitive inspections of additional parts at new inspection intervals for certain airplanes; provides new corrective actions; and provides an optional terminating action for the requirements of this AD. This AD results from the issuance of mandatory continuing airworthiness information by the Brazilian airworthiness authority. We are issuing this AD to detect and correct cracking or breaking of the rod ends and connecting fittings of the aileron PCA, which could result in reduced controllability of the airplane.
