Excessive maintenance tasks and short maintenance intervals result in high cost and low operational availability. Reliability-centered maintenance (RCM) has been successfully applied to developing initial maintenance program for new aircraft. But it is difficult to apply this concept to in-service aircraft. This paper develops a method of revising preventive maintenance requirements for in-service aircraft based on the RCM philosophy.
