Airworthiness Directives; Boeing Model 737-200 and -200C Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737-200 and -200C series airplanes, that requires repetitive inspections to find cracking of certain fuselage lap joint areas, and repair of any cracking found. This amendment also requires eventual modification of those areas, which constitutes 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.
