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 A Model for Estimating Depot Maintenance Costs for Air Force Fighter and Attack Aircraft written by Michael P. Waker and published by . This book was released on 1987 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The model developed in this study has two cost estimating relationships (CERs) for estimating depot maintenance costs in its two categories: depot maintenance cost per Promary Authorized Aircraft (PAA); and, depot maintenance cost per flying hour. The data source used for depot maintenance costs is the Weapon Systems Cost Retrieval System (WSCRS) as developed by HQ AFLC. The CERs developed used empty weight of fighter and attack aircraft to predict the cost of depot maintenance per PAA. For depot maintenance cost per flying hour, the variables used were combat radius, thrust-to-weight ratio, and empty weight. The study found that the F-111 was a significant outlier with respect to the data set, but even when included in the data base the F-111 enhanced the values of the statistics for the model and improved the ability of the model to predict. The relationship found for depot maintenance cost per PAA in the CER developed, was not as strong a predictor as was the CER developed for depot maintenance cost per flying hour. This conclusion agrees with previous studies that have tried to determine significant relationships between depot maintenance costs and those costs attributed to the number of PAA. (Theses).

Download or read book Maintenance Cost Studies of Present Aircraft Subsystems written by C. Pearlman and published by . This book was released on 1966 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes two detailed studies of actual maintenance costs for present transport aircraft. The first part describes maintenance costs for jet transport aircraft broken down into subsystem costs according to an ATA classification. From 90 airlines polled, only four were able to supply costs in this breakdown.- Despite the lack of data, multiple regression techniques were then used to demonstrate the construction of cost estimating formulae for both subsystems and a total aircraft system. The results indicate the possibility of improving present methods of estimating maintenance costs. The second part of this report briefly describes the results of an extremely detailed study of actual maintenance costs for the rotor and transmission systems of present commercial helicopters. The background information concerning each item of maintenance cost was examined to determine if it would be avoidable in the context of a mature airline operation with a full scale modification program for vehicle deficiencies. Muh, The results show that if only "normal" maintenance on rotor and transmission systems were performed, the potential maintenance costs for present helicopters are roughly 1.3 times the standard ATA estimate for fixed wing aircraft.

Available in PDF, EPUB and Kindle. Book excerpt: This book 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 possibilty of forecasting future funding requirements driven by engine component service life changes. This research concluded that the Dependability Cost Model is a powerful anagement 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.
Download or read book An Appraisal of Models Used in Life Cycle Cost Estimation for USAF Aircraft Systems written by Kenneth E. Marks and published by . 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 An Estimation of USAF Aircraft Operating and Support Cost Relations written by Gregory G. Hildebrandt and published by . This book was released on 1990 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand the availability of data to identify operating and support (O & S) costs, this Note develops aggregative cost estimating relationships to explain O & S costs. A database called VAMOSC is used in conjunction with other information on aircraft characteristics to relate O & S costs per aircraft to flying hours per aircraft, flyaway cost, number of aircraft, and design age. At the total O & S cost level, flyaway cost is an acceptable proxy for aircraft type and the mission design series year of initial operational capability. These cost estimating relationships give impressive explanatory results; whether they have equal predictive power remains to be seen. They may be helpful for assessing Air Force trade-offs between modernization and operating tempo and eventually for understanding the cost of achieving alternative readiness levels.

This book was released on 1978 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper documents a Texas Instruments 'TI Programmable 59' calculator program that uses the U.S. Air Force Cost Analysis Cost Estimating (CACE) model described in Air Force Regulation 173-10, Volume I, USAF Cost and Planning Factors, dated 6 February 1975. The CACE model was designed with a 'building block' approach to estimate annual operating costs of aircraft weapon systems. The model is useful to Air Force organizations, other Government agencies, and government contractors for cost analysis, life cycle cost exercises, or studies concerned with cost effectiveness comparisons between weapon systems. The program described in this paper provides the user with a means of using the CACE model with a hand-held programmable calculator, eliminating lengthy manual computation or the necessity of using a computer. With its calculator connected to the Texas Instruments 'PC-100A Print Cradle, ' the program allows the user to select among several cost factor input methods, estimate output formats, and summarization options.
