This book was released on 1994 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores the use of a computerized aircraft maintenance system cost model to analyze the F/A-18 engine maintenance system. The Dependability Cost Model is a Paradox Data Base model, developed by the Boeing Corporation, and is currently used in the airline industry to estimate costs associated with maintaining aircraft or the implementation of service bulletin changes to the aircraft. Research was conducted to determine the feasibility of adapting this model to the F/A-18 using existing maintenance information systems, and the possibility of forecasting future funding requirements driven by engine component service life changes. This research concluded that the Dependability Cost Model is a powerful management tool in the analysis of aircraft maintenance System costs. However, its use as a budget estimation tool in a rapidly changing cost environment presented a number of difficulties and yielded marginal results.

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 1977 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is an attempt to locate, analyze and evaluate data bases which contain operation and support (O and S) cost data for aircraft engines. The search for these data bases was primarily conducted at Headquarters, Air Force Logistics Command. The study focused upon the Increase Reliability of Systems (IROS) data base, the HO36B DOD Cost and Production Report, the AFM 400-1 actuarial data system, the cost and planning factors in AFR 173-10, aerospace ground equipment data located in the Tables of Allowance, and Component Improvement Program data located at the Deputy for Propulsion, Aeronautical Systems Division. The study of these data bases led to the conclusion that data bases in the Air Force are not well designed for cost data collection and that many data bases are necessary to obtain the total operation and support cost of an aircraft engine.

Download or read book Modeling F A 18 Flight Hour Program Costs Using Regression Analysis written by Larry E. Arkley and published by . This book was released on 1994 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is an in depth analysis of cost variance in Naval Air Reserve units flying the McDonnell Douglas F/A-18. The purpose of the thesis is to identify, analyze and quantify the effect of variances in the cost per flight hour of the Naval Air Reserve's Flying Hour Program. The study begins with a review of the Planning, Programming, and Budgeting System which is used to justify and fund the Flying Hour Program. Then three different methods of determining Flying Hour Program requirements are described. The four components of cost per hour within the Flying Hour Program (Fuel, Organizational Maintenance Activity, Intermediate Maintenance Activity and Aviation Depot Level Repairables) are defined. Finally, using regression analysis techniques, these four components of F/A-18 cost data are analyzed on the basis of the intensity of aircraft utilization: flight hours. The analysis includes a regression model to provide budgeters at the headquarter or squadron level the means for predicting aircraft maintenance and fuel costs given a utilization rate. The thesis concludes with areas recommended for further research.

Download or read book Aircraft Engine Maintenance Study written by James R. Capra and published by . This book was released on 1975 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study reviews three problem areas of aircraft engine maintenance in the Navy: the setting of maximum operating time, the performance of overhauls for cause instead of repairs, and the site of engine repair. All of the problem areas affect in some way the number of engine overhauls performed annually. The study assesses the effectiveness of engine overhaul from a safety and reliability standpoint by analyzing Navy data on engine-related aircraft mishaps and engine removals. The analysis revealed that within the current range of operations engines wear in but under current policies of continued repair/replacement and relatively short times between overhauls, engines as a system do not wear out. Consequently, policies which would decrease the number of overhauls performed annually and increase the time between overhauls appear to be reasonable from a reliability and safety standpoint. Using a model of the engine repair and overhaul pipeline, the study finds that three new policies, two of which would increase the time between overhauls, result in lower annual maintenance costs and improved spare engine availability.

Download or read book Evaluation of F 15 Operations and Maintenance Costs Based on Analysis of Category II Test Program Maintenance Data written by Christopher B. Howard and published by . This book was released on 1975 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report contains an analysis of the maintenance data collected as part of the F-15 Category II test program from April 1974 through February 1975 with the intent of updating operations and maintenance cost predictions. A brief review of the Systems Effectiveness Data System is included to provide background on the source of the raw maintenance data. This is followed by an analysis of maintenance man-hours per flight hour (MMH/FM) trends based on regression analysis to determine the expected operational maintenance requirements. Failure data are analyzed to determine system and subsystems reliability. Two reliability models are used for this analysis: an exponential model which assumes a constant instantaneous failure rate, and a Weibull model which can represent either an increasing or a decreasing failure rate.
Download or read book Cost Effectiveness of Two Versus Three Levels of Maintenance for Turbine Engines in the Air Force Inventory written by John T. Schiefen and published by . This book was released on 1990 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the life cycle costs (LCC) for Air Force turbine engines. Specifically, the research compared the costs for two, three, and modified three level maintenance concepts. To achieve the research objectives, a LCC model, the 'Super Operating and Support Cost Model (SOSCM), ' was used. SOSCM is used by the Propulsion SPO, ASD/YZ, at Wright Patterson AFB to estimate costs for Air Force engines. A sensitivity analysis was run on a generic test case to determine the effect of changes in certain cost drivers on LCC. There were a few important findings. First, for this case, the LCC for the two level concept was 14.7% greater than the cost for three levels of maintenance. Two factors accounted for most of the difference. The number of spare engines required increased, the second destination transportation costs rose sharply. The study also showed that changes in some factors have a greater impact on the costs for two levels of maintenance than three. Overall, the research points out that it should not be assumed that moving to two levels of maintenance will lower costs. Engine types should be considered individually to determine the most cost effective maintenance concept. Keywords: Jet engines, Life cycle costs, Cost analysis, Maintenance, Theses.
Download or read book Environmental Effects on Maintenance Costs for Aircraft Equipment written by and published by . This book was released on 1976 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of mathematical models of the influence of environmental effects on maintenance costs was constructed using linear regression analysis. The equipment whose behavior were modeled were the KC-135 Doppler Radar and the F-4E engine starter. Models explaining more than 20% of the variation in maintenance cost as a result of weather factors were developed, where only the two most current month's weather was considered. Recommendations for further research using more sophisticated model development techniques are presented. A limited economic analysis of some life cycle cost implications of failure countermeasures for increased environmental resistance is given.
Download or read book Development of Cost Estimating Relationships for Aircraft Jet Core Engine Overhaul Costs written by Robert A Breglio (Jr) and published by . This book was released on 1977 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost estimation is a wide open area within the Department of Defense and accurate cost estimating models are a valuable tool in the life cycle costing of a weapon system. This research effort utilized multiple linear regression analysis to develop parametric cost models or cost estimating relationships (CERs) for jet engine depot overhaul costs. Both engine operating parameters, e.g., turbine inlet temperature, RPM, etc., and engine physical characteristics, e.g., length, weight etc., were considered as probable cost drivers. Extensive analysis was performed to determine the reliability of the data base. The major finding of this study was that models can be developed with acceptable explanatory power, with respect to variation in the data base, using data of questionable reliability. Thus, a model developed should not be accepted on the basis of explanatory power alone but should be tested further to determine its utility as a cost estimator. (Author).
Download or read book Estimating Aircraft Depot Maintenance Costs written by Kenneth E. Marks and published by RAND Corporation. This book was released on 1981-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a series of parametric equations for use in estimating the depot maintenance cost of new Air Force aircraft, particularly for the five major maintenance categories: airframe rework, engine overhaul, airframe component repair, engine component and accessory repair, and avionics component repair. The equations are intended to provide cost estimates for Defense Systems Acquisition Review Council Milestone II, at which point some design details of major aircraft subsystems (airframe, engine, avionics) are available. The report presents a single set of equations that are the most representative and applicable to the widest range of estimating situations, but presents alternative equations and supporting data and analyses for use by the interested reader.
Download or read book Maintainability Reliability Impact on SYSTEM Support Costs written by and published by . This book was released on 1973 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical report addresses life cycle costs for fighter type aircraft, with emphasis on analysis performed during the early design phase. The engineer is provided a discussion of the factors and guidelines for estimating major elements of the life cycle costs for new or existing weapon systems using field experience data and cost planning factors from AFM 173-10. It does not include a computer model. Charts and curves are included which show how reliability and maintenance impact support costs during a program's operational phase. Quantifiable support cost savings have been calculated on the F-4, F-111, and A-7D aircraft to demonstrate the analytical approach and rationale used in performing the analysis.
