The U.S. Air Force is grappling with the challenge of aging fleets and the optimal time to replace them. This monograph examines commercial aviation data to draw inferences about aging aircraft that may be relevant to the Air Force. It focuses on "aging effects"-i.e., how aircraft maintenance costs change as aircraft grow older. Although commercial aircraft clearly differ from military aircraft, the aging-effect estimates might help the Air Force to project changing maintenance costs over time.

Seminar paper from the year 2014 in the subject Engineering - Aerospace Technology, grade: 1,3, University of Applied Sciences Wildau (Wildau Institute of Technology), course: Aviation Management 2012, language: English, abstract: Indeed, the majority of airlines are faced with the challenge of aging fleets and when it might be optimal to replace older aircraft. Well, any discussion of the wisdom of retaining capital equipment is usually based on economic arguments. In a competitive environment, airlines are continuously obliged to improve their business and equipment to stay profitable. The prediction of future maintenance costs of the own fleet is an integral element of prospective budgeting projections; on the other hand they serve as a vital part within aircraft replacement calculations. For example if the costs of maintaining the existing equipment on a timely basis exceeds the capital, interest, and amortization charges on replacement equipment, the decision to buy a sort of replacement is straightforward. In most cases the substitute equipment even offers an improved productivity as well (Dixon 2006, p. 1). Beside any debate concerning costs and efficiency, flight safety considerations also enter into the discussion especially in the field of aviation. The question to repair or replace is an ongoing decision making process for the maintenance department of every airline operator. Now the key questions to be answered in this context are: Is it possible to describe a standard airplane service life and how does the fleet age of world’s leading airlines look like? How does the process of maintenance develop over an aircraft’s whole life cycle and can necessary costs be estimated? What can be done technically to keep aging effects of aircraft under control and when might be the right time to withdraw an aircraft from service? In order to answer the abundance of questions my term paper is divided into an economic based part including compiled data and statistics and a more technical part. In the beginning, this paper investigates the ordinary economic life of commercial airplanes. Additionally I’m going to inspect exemplary the average fleet age of world’s leading airlines. In the second stage I am going to describe how to estimate maintenance costs of aircraft that grow older. Further I wanted to clarify technical aspects and problems that might occur more frequently with the rising age of an 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.

Over the next 20 years, the further aging of already-old aircraft will introduce challenges and issues for aircraft operators. The technical challenges relate to structures, propulsion, and systems. The institutional challenges include limitations on independent verification of fleet status and future condition and on information needed for engineering analyses including risk assessment, and an overall scarcity of resources.

The theme of this book is that 21st Century Technology aircraft (NEXGEN) has out paced the data and knowledge for aging aircraft programs today. Persons involved with NEXGEN aircraft have minimum historical data and knowledge to base maintenance practices on to ensure airworthiness. The economy of the industry for the last twenty years has resulted in reducing maintenance training to diminish maintenance costs and by using contract onshore and offshore facilities for maintenance and inspection. This mixture of maintenance actions has left the industry vulnerable to sub-grade maintenance practices on aging aircraft as well as NEXGEN aircraft. Aging Aircraft Structural Programs parameters and time lines do not track the same as Aging Aircraft Nonstructural Programs; e.g. computer, electronic, electric, fuel and hydraulic systems. The Aging Nonstructural Systems Research began with a White House Commission on Aviation Safety and Security in 1997 by the Federal Aviation Administration (FAA) William J. Hughes Technical Center and is still being studied today. Meanwhile NEXGEN aircraft experience system failures around the world.

As part of a continuing project on aging aircraft and the replacement-or-repair decision, the authors develop a parsimonious model of the decision and apply it to the U.S. Air Force's C-21A transport and KC-135 tanker aircraft. They find that, for the C-21A, it probably would be appropriate to undertake a 20,000 flight hour system and component replacement schedule-prescribed renovation in the 2012 timeframe, but the aircraft should be retired around 2020. For the KC-135 tanker, it would be optimal to replace the KC-135 before the end of the decade

Part of a larger RAND Project Air Force study on capability-based programming, 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). Such a valuation estimate would be useful in depot-level cost-benefit analysis. The authors rely on the fact that the Air Force has chosen to pay for intermittent PDM on F-15s to assert that F-15s must have enough value after PDM visits to justify PDM costs. Air Force expenditure data suggest that a typical fiscal year 2005 PDM visit cost about $3.2 million. Using the aircraft valuation curves consistent with PDM being worthwhile, the authors find that expediting an F-15's last PDM visit by a month must be worth at least $60,000. However, using a plausible annual aircraft valuation decline rate, they find that expediting an old F-15's last PDM visit by a month would be worth around $75,000, while expediting a new F-15's first PDM visit by a month would be worth more than $180,000. This report also explores various robustness enhancements. Consideration of aging aircraft issues, for instance, tends to increase the estimated value of expedited PDM.
