## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-135ER and -135LR series airplanes, and Model EMB-145, -145ER, -145MR, and -145LR series airplanes. This action requires a one-time visual inspection to determine if the two bonding jumpers that connect the horizontal stabilizer to the vertical stabilizer are properly installed, and replacement of the jumper with a new jumper, if necessary. This action also requires a one-time visual inspection to determine if the supports that connect the bonding jumpers to the horizontal stabilizer are deformed, and corrective actions, if necessary. This action is necessary to prevent severed bonding jumpers in the event of a lightning strike, which could result in reduced elevator control capability, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
