Summary
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for all EMBRAER Model EMB 135 and EMB 145, 145ER, 145MR, 145LR, 145XR, 145MP, and 145EP airplanes. The proposed AD would have required inspecting to determine the part number of the ailerons. For airplanes with affected aileron part numbers, the proposed AD would have required reworking the aileron damper fitting, and for certain airplanes, replacing the rod end of the aileron damper assembly with an improved rod end. Since the proposed AD was issued, we have received new data indicating that there is no unsafe condition associated with structural failure of the rod end of the aileron damper. Accordingly, the proposed AD is withdrawn.
