Esta DA requer inspeção repetitiva de suportes de pedal do R/C com números de peça específicos e, dependendo dos resultados, substituição do suporte de pedal do R/C ou reacabamento de quaisquer áreas expostas. Esta DA também proíbe a instalação de suportes de pedal do R/C com números de peça específicos. A FAA está emitindo esta DA para solucionar a condição de segurança inadequada nesses produtos.
