Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-200 and -200C series airplanes. This proposal would require repetitive inspections to find cracking of certain fuselage lap joint areas, and repair of any cracking found. This proposal also would require eventual modification of those areas, which would constitute terminating action for the repetitive inspections. This action is necessary to find and fix cracking of certain fuselage lap joint areas, which could result in rapid decompression of the airplane. This action is intended to address the identified unsafe condition.
