## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-102, -103, and -106 airplanes; Model DHC-8-201 and -202 airplanes; and Model DHC-8-301, -311, and -315 airplanes; that would have required replacement of the elevator stop bumpers of the horizontal stabilizer with new bumpers. Among other actions, this new action revises the proposed rule by incorporating revised replacement intervals for the elevator stop bumpers into the applicable airworthiness limitation. This action is necessary to prevent damage to the elevator trailing edge due to a broken or missing elevator stop bumper, which could result in jamming of the spring tab and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
