## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain de Havilland Model DHC-8- 100 series airplanes. This proposal would require a one-time visual inspection to determine the presence of block seals on the upper portions of the cabin/baggage compartment bulkheads, and installation of a new or serviceable block seal for any missing block seal. This proposal is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent smoke contamination of the passenger and crew cabins, in the event of fire or smoke in the baggage compartment, due to a direct smoke path between the baggage compartment and the cabins.
