Abstract
This amendment adopts a new airworthiness directive (AD), applicable to certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120 series airplanes, that requires installing a lightning bonding jumper from the lower rotating beacon to the airframe. This action is necessary to prevent possible multiple avionics failures caused by a lightning strike, which could reduce the ability of the flightcrew to control the airplane. This action is intended to address the identified unsafe condition.
