747 maintenance - Boeing 747 | information center

Boeing, the U.S. Federal Aviation Administration, and 747 operators have completed a three-year effort to update the required scheduled maintenance programs for the 747-100/-200/-300 and the 747-400. The revisions offer significant cost savings for both new and current operators of 747 airplanes. I n response to customer requests
to improve maintenance programsfor out-of-production airplanes, Boeing initiated an effort in 1999 to update the maturing maintenance program for the 747-100/-200/-300
(i.e., 747 Classic). Because the 747 Classic and 747-400 are structurally similar, Boeing and the industry decided to update the maintenance program for the 747-400 at the same time. The revised maintenance requirements comply with industrywide maintenance practices developed by the Air Transport Association (ATA) Maintenance Steering Group (MSG), a group of airframe manufacturers, airlines, U.S. Federal Aviation Administration (FAA) representatives, and suppliers.
