Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This dissertation's objective is to assist the Air Force (AF) in making difficult yet necessary choices regarding its aging fleets in order to fulfill national security objectives at lowest cost. Costs related to maintenance are a key component to the AF's decision-making process. In general, AF fleets are aging. This motivates the AF to want accurate maintenance cost forecasts. Forecasts of its current fleets and future replacement fleets are necessary. This dissertation will use commercial airline data to help the AF make these difficult choices.

This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: RAND Project AIR FORCE'S long term interest in the topic of aging aircraft was rekindled in 1994, when we participated in the Air Force Scientific Advisory Board Summer Study that raised technical concerns about the viability of retaining certain aircraft past their original design lives. In 1997, the National Research Council's report on aging USAF aircraft reinforced those concerns. At that time, we initiated a modest Air Force sponsored research effort focused on emerging technical challenges for aircraft maintenance activities. Last summer we built on that technical background to examine the potential effects that aging aircraft would have on the costs of programmed depot maintenance (PDM) and engine support. The results of that work are documented in the annotated briefing that has been made available to the subcommittee. This year, we have broadened our review to cover other support and modernization activities where aircraft age may affect costs and readiness.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As many of its fleets of legacy aircraft types are kept in service well beyond their planned services lives (sometimes in age, sometimes in usage, sometimes both), the United States Air Force (USAF) faces numerous engineering and resource challenges for the continued, cost effective sustainment of those aging systems. This report details the recommendations made by the USAF Scientific Advisory Board's Sustaining Aging Aircraft (SAA) Study to best position the Air Force to meet those challenges. The SAA Study Panel visited a cross section of military and commercial aircraft maintenance organizations to assess sustainment practices and identify technologies that can extend system life and ease maintenance costs. The Study identified specific aircraft systems, in addition to structures and engines, that contribute to safety, availability, and effectiveness for aging aircraft; examined commercial practices in airlines, air freight services, and other industries, and evaluated how they might be applied to meet USAF needs; and identified technology needs and technology approaches that can be applied or developed to extend life or ease maintenance of these aircraft systems, while facilitating future adaptations and performance enhancements of the aircraft."--p. 211.

Download or read book Shock n awe in 21st Century Aviation Maintenance written by Algy F. Giles and published by CreateSpace. This book was released on 2010-03-23 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Operating Costs of Aging Air Force Aircraft written by United States. Congressional Budget Office and published by . This book was released on 2018 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: As aircraft age, they generally become more expensive to operate. The rate at which those operating costs grow is important for setting operating budgets and for deciding when to replace aging systems. The faster costs grow as a system ages, the more funding will be needed to maintain existing aircraft and the sooner it becomes cost-effective to replace aging systems with new aircraft. The rate of cost growth associated with the aging of Air Force aircraft has increased in recent years. Growth in the total Air Force budget during the 2000s appears to explain a considerable portion of the higher estimated annual growth rates in operating costs per flying hour beyond the growth rate intrinsic to the aging of the fleet. In other words, because the Air Force had more resources available, it was able to increase spending on aircraft operation and maintenance.
Download or read book Commander Naval Air Forces CNAF Aircraft Operations Maintenance AOM written by Kenny K. Chase and published by . This book was released on 2006 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Naval aviation serves as a vital component of many air and ground task organized forces vying for a share of the Department of Defense (DoD) budget. The decisions in the 1990s to reduce purchases of new equipment left the Navy with aging fleets of aircraft that are increasingly expensive to maintain. This situation coupled with the cost of the Global War on Terror has created a cycle in which more funds are spent maintaining older equipment at the expense of new purchases. This has lead to still older equipment and higher maintenance costs. The increases in the costs of operating and maintaining aging military equipment have created a budgetary crisis in the Department of Defense. The Commander Naval Air Forces (CNAF), Commander, Naval Air Force, U.S. Pacific Fleet (COMNAVAIRPAC), and Commander, Naval Air Force, U.S. Atlantic Fleet (COMNAVAIRLANT), face the great challenge of effectively vying for their share of the 37 percent of the DoD budget that pays for the day-to-day costs of Operation and Maintenance (O & M). Precisely identifying budgeting and costs for sustaining Aircraft Operations Maintenance (AOM) of the Navy's aging fleet of aircraft is vital to preserving an essential component of current war fighting doctrine. Unfortunately, establishing the association between age and costs is complex. Costs are likely to be affected by an aircraft's age, component technology, the number of flight hours, manner in which it is flown, and the resources devoted to maintenance. Therefore, to better identify costs and maintenance trends of value to Naval aviation, the cost drivers for AOM should be investigated. The purpose of this study is to analyze the effectiveness of the aircraft maintenance process in conjunction with actions to remove impediments to non-deployed aviation readiness. The methodology for the study will involve an analysis of specific changes in training personnel, equipping depots, executing programs, and utilizing infrastructure, along with a review of the end results of these changes.
