Douglas Aging Aircraft Programs

Modern design practices for long-life aircraft and how they relate to the current aging aircraft fleet situation are presented. Concepts of the maintenance programs are also introduced along with means of modifying the program to protect the aircraft against the increased probability of fatigue and corrosion as the aircraft ages. Special programs by the manufacturer, such as extended fatigue testing and on-site aircraft evaluations, are discussed. The recent aging aircraft activities sponsored by the ATA and AIA are also examined.
