## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 737-600, -700, -700C, and -800 series airplanes. This action prohibits installation of repairs of the elevator tab using previously approved repair procedures. This action is necessary to prevent installation of repairs of the elevator tab that are outside allowable limits, which could result in excessive in- flight vibrations of the elevator tab, and consequent loss of controllability of the airplane.
