Abstract
We are adopting a new airworthiness directive (AD) for certain Model 747-100, 747-200B, 747-300, and 747SR series airplanes. This AD requires installation of a closeout panel and moisture curtains for the main equipment center. This AD results from a report of water contamination in the electrical and electronic units in the main equipment center. We are issuing this AD to prevent the malfunction of one or more electrical and electronic units in the main equipment center, which could adversely affect the airplane's continued safe flight.
