## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-145 series airplanes. This proposal would require inspection of the bolts on the hinge fittings that attach the spring tab and the servo tab to the rear spar of the elevators for evidence of loosening; inspection of the region of the hinge fittings on the spring tab for interference of the bonding jumpers attached to the hinge fittings with the leading edge of the spring tab; and corrective action, if necessary. The proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign airworthiness authority. The action specified by the proposed AD is intended to prevent the spring tab or the servo tab from becoming disconnected, resulting in structural failure. The action is also intended to prevent damage to the leading edge of the spring tab, which could result in loss of control of the elevator.
