Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-200 series airplanes. This proposal would require removal of the existing emergency floor path lighting system and replacement with an FAA- approved emergency floor path lighting system. This proposal is prompted by information indicating that the existing emergency floor path lighting system does not provide adequate lighting and cueing for safe evacuation of the airplane in the event of an emergency. The actions specified by the proposed AD are intended to prevent such inadequate lighting and cueing, which could delay or impede the flight crew and passengers when exiting the airplane during an emergency.
