Airworthiness Directives; Boeing Model 747 Series Airplanes

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 747 series airplanes. This proposal would require replacement of the existing pressure relief valve in the potable water system with a non- adjustable, single setting valve. This proposal is prompted by reports of potable water tanks that ruptured and resulted in damage to the passenger compartment. The actions specified by the proposed AD are intended to prevent injury to the crew and passengers and damage to the passenger compartment, due to an explosive failure of the potable water tank.
