Summary
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Fokker Model F28 Mark 0100 series airplanes, that would have required installation of additional ``EXIT'' signs at the overwing emergency exits. That proposal was prompted by a report indicating that the ``EXIT'' signs for the overwing emergency exits, as currently installed, would not be visible to passengers during an emergency evacuation when the emergency exit doors are open. This action revises the proposed rule by expanding the applicability of the proposed rule to include additional airplanes. The actions specified by this proposed AD are intended to ensure the ``EXIT'' signs for overwing emergency exits are clearly visible during an evacuation.
