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.

This book was released on 1978 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although life cycle analysis is widely used as a management tool, considerable uncertainty still exists about its effectiveness with respect to economic tradeoffs, funding decisions, and resource allocations. This report evaluates some of the most widely used life cycle cost models: AFR l73-10 models (BACE and CACE); the Logistics Support Cost model; the Logistics Composite model; the MOD-METRIC model; AFM 26-3 Manpower Standards; Air Force Logistics Command Depot Maintenance Cost Equations; the DAPCA model; and the PRICE model. The models are rated within a framework incorporating a set of cycle cost elements and a set of cost driving factors. Color-coded illustrations summarize the results. The models are shown to have many shortcomings that limit their usefulness for life cycle analyses in which estimates of absolute, incremental cost are required. Specific areas are identified where driving factor/cost element combinations are not adequately addressed.
Download or read book Life Cycle Cost Modeling and Simulation to Determine the Economic Service Life of Aging Aircraft written by K. R. Sperry and published by . This book was released on 2003 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimating the point at which the advantages of a modem aircraft alternative exceed the economic burden of maintaining aging aircraft is very complex. This paper presents a cost estimating methodology to forecast costs associated with * maintaining an aging aircraft fleet, by combining traditional Operation and Support (O & S) cost elements from a USAF AFI 65-503 CORE model, with expert analysis to quantify maintenance cost growth due to aging. The result is an Economic Service Life (ESL) model that can be used to determine the economic service life of an aircraft. The uncertainties associated with long-range forecasting are considered by combining range estimates within a Monte Carlo simulation for each critical input variable.

Available in PDF, EPUB and Kindle. Book excerpt: This document describes a life cycle cost model for commercial aircraft composite structure. The term life cycle cost used herein, refers to the airline costs for maintenance, spares support, fuel, repair material and labor associated with composites after introduction into service and throughout its useful life. This document contains the equations that can be programmed into software which is used to estimate the total cost of ownership aircraft, including structure. Modification costs and operating costs are estimated over a specified life (any period up to 30 years). Modification costs include spares holding, training, support equipment, and other system related costs. Annual operating costs include: Schedule interruption, fuel, spares, insurance, and maintenance. Maintenance costs are separated by scheduled maintenance or unscheduled damage, or can by grouped into the typical organizations of line, shop, and hangar maintenance. This Lifecycle Cost allows users to evaluate the impact of Service Bulletins, potential design changes, changes in maintenance programs, or effectiveness of maintenance operations. AIR5416 has been reaffirmed to comply with the SAE five-year review policy.
Download or read book Maintenance Costs and Life Cycle Cost Analysis written by Diego Galar and published by CRC Press. This book was released on 2017-09-18 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Authors have attempted to create coherent chapters and sections on how the fundamentals of maintenance cost should be organized, to present them in a logical and sequential order. Necessarily, the text starts with importance of maintenance function in the organization and moves to life cycle cost (LCC) considerations followed by the budgeting constraints. In the process, they have intentionally postponed the discussion about intangible costs and downtime costs later on in the book mainly due to the controversial part of it when arguing with managers. The book will be concluding with a short description of a number of sectors where maintenance cost is of critical importance. The goal is to train the readers for a deeper study and understanding of these elements for decision making in maintenance, more specifically in the context of asset management. This book is intended for managers, engineers, researchers, and practitioners, directly or indirectly involved in the area of maintenance. The book is focused to contribute towards better understanding of maintenance cost and use of this knowledge to improve the maintenance process. Key Features: • Emphasis on maintenance cost and life cycle cost especially under uncertainty. • Systematic approach of how cost models can be applied and used in the maintenance field. • Compiles and reviews existing maintenance cost models. • Consequential and direct costs considered. • Comparison of maintenance costs in different sectors, infrastructure, manufacturing, transport.

Download or read book Life Cycle Analysis Procedures and Techniques written by K. E. Marks and published by . This book was released on 1977 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A briefing discussing the application of life cycle analysis to the evaluation of proposed investments of R & D and procurement funds. The primary focus of this study has been on aircraft systems and on decisions involving program changes and modifications to systems already in acquisition. In summary, it was observed that present procedures and techniques for making life cycle cost estimates can lead to decisions that have effects opposite to what the decisionmaker is seeking. Opportunities to reduce overall costs may be missed. R & D funds may be invested without achieving an expected O & S cost reduction, thereby increasing life cycle cost. The establishment of a uniform set of procedures for conducting and presenting the results of life cycle analyses should help in two ways. It would compensate for some of the shortcomings of current models and data, and it would provide a useful basis for the development of improved estimating techniques in the future.

Download or read book Condition Based Maintenance in Aviation written by Ravi Rajamani and published by SAE International. This book was released on 2018-12-11 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Condition-Based Maintenance in Aviation: The History, The Business and The Technology describes the history and practice of Condition-Based Maintenance (CBM) systems by showcasing ten technical papers from the archives of SAE International, stretching from the dawn of the jet age down to the present times. By scientifically understanding how different components degrade during operations, it is possible to schedule inspections, repairs, and overhauls at appropriate intervals so that any incipient failure can be detected well in advance. Today, this includes more sensors and analytics so that periodic inspections are replaced by automated "continuous" inspections, and analytical methods that detect imminent failures and predict degradation issues more economically and efficiently. Similar concepts are also being developed for delivering prognostics functions, such as tracking of remaining useful life (RUL) of life-limited parts in aircraft engines. The discipline within CBM that deals with this is called prognostics and health management (PHM), which covers all aspects of diagnostics and prognostics, including modeling of systems and subsystems, sensing, data transmission, storage and retrieval, analytical methods, and decision making. Traditionally, nondestructive testing (NDT) methods have been employed during the major airplane checks to assess structural damage. These techniques are enhanced with in- situ sensing techniques that can continuously monitor aircraft structures and report on their health. The move to condition-based assessment of maintenance needs to be balanced by the assurance that safety is not compromised, that initial cost of new equipment is amortized by the savings, and that regulatory authorities are on board with any modifications to the planned maintenance schedule. The trend is clearly to include more CBM functions into Maintenance, Repair and Overhaul (MRO) processes so better cost control can be achieved without ever comprising passenger safety.

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.
