This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2009-15-16 that was sent previously to all known U.S. owners and operators of the McDonnell Douglas Corporation airplanes identified above by individual notices. This AD requires modifying the flight deck door. This AD is prompted by a report indicating that certain equipment of the flight deck door is defective. We are issuing this AD to prevent failure of this equipment, which could jeopardize flight safety.
