The Air Force has adopted a strategy for maintenance of its C-5 planes based on the idea that more problems can be avoided and efficiency increased with regular upkeep. "When a part breaks, we change it, wherever in the world the plane might be. This is more of a preventative mentality, where we change something on schedule," said Don Daley, the C-5 weapon system manager for Air Mobility Command. The program, called Maintenance Steering Group-3, will ensure that planes are inspected every 16 months, with more intensive checkups at four- and eight-year intervals. The mission-capable rates of inspected planes have increased by an average of about 14%.
