Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747-100, -200B, -200C, -200F, - 300, -400, -400F, and 747SR series airplanes equipped with a MCSCD manufactured by Boeing. This action requires repetitive inspections for cracking of the lower lobe panel of the fuselage skin of the aft cargo bay, and repair if necessary. This action is necessary to find and fix cracking of the skin, which could lead to reduced structural integrity of the side cargo door cutout of the main deck, and result in rapid depressurization of the airplane. This action is intended to address the identified unsafe condition.
