## Summary

This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-135 and EMB-145 series airplanes. That action would have required an inspection of the base and support surfaces of the glide slope antenna and of certain electrical connectors of the navigation system, and applicable corrective actions if necessary. Since the issuance of the NPRM, we have received new data showing that the proposed inspection and corrective actions will not eliminate the display of erroneous or misleading information to the flightcrew in the cockpit. However, we have been informed that the navigation system manufacturer has developed effective corrective actions to address the unsafe condition identified in the NPRM. Since we issued the NPRM, we have issued other rulemaking, which provides corrective actions for the identified unsafe condition. Accordingly, the proposed rule is withdrawn.
