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

Краткое содержание

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model EMB-145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The existing 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 proposed AD would require the same repetitive inspections of additional parts at new inspection intervals for certain airplanes; provide new corrective actions; and provide an optional terminating action for the proposed requirements. This proposed AD results from the issuance of mandatory continuing airworthiness information by the Brazilian airworthiness authority. We are proposing 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.
