## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Bombardier Model DHC-8- 102, -103, -106, -201, -202, -301, -311, and -315 series airplanes. This proposed AD would require modification of the wiring of the emergency lighting system. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The action specified by the proposed AD is intended to prevent the pilots from having full authority over the cabin emergency lights, which could result in delayed egress of the passengers and crew from the cabin during emergency evacuation.
