Resumen

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-10, -20, -30, -40, and -50 series airplanes; C-9 airplanes; and Model DC-9-81, -82, and - 83 series airplanes. This AD requires modification of the light switch for the cargo compartment(s).

This action is intended to address the identified unsafe condition.
