Full official abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain de Havilland Model DHC-7 series airplanes, that requires modification of the power control relay installation of the emergency lights. This amendment also requires revising the FAA- approved Airplane Flight Manual to include procedures for turning off and on the emergency lights switch in certain conditions. This amendment is prompted by a report that the emergency lights do not automatically illuminate when all generated electrical power on the airplane is lost and the power to the left essential bus is maintained from the aircraft batteries. The actions specified by this AD are intended to ensure that the emergency lights illuminate when needed in an emergency situation.
