## Abstract

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2009-19-06 that was sent previously by individual notices to the known U.S. owners and operators of affected airplanes identified above. This AD requires installing certain equipment on the flight deck door. This AD was prompted by reports that the current design of the flight deck door is defective. We are issuing this AD to prevent failure of this equipment, which could jeopardize flight safety.
