## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 737-100, -200, -200C, -300, -400, and - 500 series airplanes. For certain airplanes, this amendment requires a one-time inspection or a review of the maintenance records of the airplane to determine if a particular control rod barrel for the aileron tabs is installed, and follow-on repetitive inspections for cracking of the control rod barrels and replacement of the control rod barrels with new barrels, if necessary. Such replacement terminates the repetitive inspections. For all airplanes, this amendment prohibits installation of a certain control rod barrel for the aileron tabs. The actions specified by this AD are intended to prevent the disconnection of an aileron tab, which could lead to severe airframe vibrations; consequent damage to the aileron tab, aileron, and wing; and possible loss of controllability of the airplane. This action is intended to address the identified unsafe condition.
