## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model EMB-135BJ, -135ER, - 135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The existing AD currently requires reviewing the airplane maintenance records for recent reports of vibration from the tail section or rudder pedals. The existing AD also currently requires repetitively inspecting the skin, attachment fittings, and control rods of rudder II to detect cracking, loose parts, wear, or damage; and related investigative/corrective actions if necessary. This proposed AD would require the existing repetitive inspection to be done with new service information. This proposed AD also would require replacing the locking tab washers on the control rods of the rudder II and installing springs on the hinge assemblies of the rudder II, which would terminate the repetitive inspection requirements. This proposed AD results from reports of rudder vibration due to wear. We are proposing this AD to prevent failure of the rudder control rods, which could result in jamming of the rudder II, and possible structural failure and reduced controllability of the airplane.
