When is it more cost efficient to replace an aircraft rather than continue to maintain it?

Aging U.S. Air Force fleets have deterioration problems, resulting in increased maintenance workloads. Programmed depot maintenance (PDM) is significant, requiring 2,000 to 50,000 labor hours and material. RAND developed the PDM Capacity Assessment Tool (PDMCAT), applied it to the KC-135 PDM process, with three alternative forecasts of future workload and two fleet-size scenarios, to inform aircraft availability and resource allocation decisions.

This report introduces a revealed preference methodology to estimate the value to the United States Air Force of expediting F-15 fighter jet programmed depot maintenance (PDM). The Air Force has chosen to pay for intermittent PDM on F-15s, so F-15s must have enough value after PDM visits to justify PDM costs. Computations suggest expediting F-15 PDM by a month would be worth at least $75,000, but likely considerably more for younger aircraft.

To help improve the Air Force's ability to foresee the implications for safety, aircraft availability, and cost of its plans to retain aircraft fleets for service lives that may be as long as 80 years, and to identify actions that will mitigate or avoid some of the more severe consequences, this study measures how the USAF aircraft fleets' ages relate to maintenance and modification workloads and material consumption.

The U.S. Air Force is grappling with the challenge of aging fleets and when it might be optimal to replace those fleets. This monograph examines commercial aviation data with the goal of drawing inferences and lessons about aging aircraft that may be relevant to the Air Force. It focuses on "aging effects" - i.e., how commercial aircraft maintenance costs change as aircraft grow older. Although commercial aircraft clearly differ from military aircraft, commercial aviation aging-effect estimates might help the Air Force to project how its maintenance costs will change over time and how those costs might evolve for new commercially analogous aircraft not yet in its inventory. This study found that commercial-airline inflation-adjusted total aircraft maintenance costs, per flight hour, rise substantially as aircraft come off the manufacturer's warranty after a few years of operation, and then rise at about a 3.5 percent annual rate for aircraft six to 12 years old, but are nearly unchanged for aircraft 12 to 25 years old.

The RAND National Defense Research Institute examined Department of Defense depot-level reparable (DLR) supply chain management to assess how it could be improved to enhance customer support and reduce costs. This report concludes that DLR supply chain management appears to be done relatively effectively across the services. What on the surface appears to be substantial inventory excess and high disposals of assets is instead a reflection of the fact that DLRs are durable assets very much like weapon systems and other end items. Most DLRs have very low condemnation rates, with depot maintenance economically repairing them time and again through the life of the supported end item. So when they are replaced by upgraded versions or weapon systems are phased out, demand disappears but the assets remain, leading first to "excess" inventory and then to disposals. This is a cost of doing business. As a result, no large, "silver bullet" solutions were found. Still, a number of modest opportunities for improving DLR supply chain management were identified. The first is improving parts supportability, including taking a total cost perspective that encompasses supply and maintenance costs when planning inventory in support of depot production. The second is to shift the Army more toward pull production. The third is to reduce lead times for all types of contracts affecting DLR supply chain management. And the fourth is to better account for all resource lead times in planning DLR production and for anticipatable shifts in procurement and repair needs. All of these enhancements would improve customer support, with better parts support likely reducing maintenance costs and pull production reducing the buildup of inventory.
