Report on Sustaining Air Force Aging Aircraft Into the 21st Century


Book Description

"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.




Aging of U.S. Air Force Aircraft


Book Description

Many of the aircraft that form the backbone of the U.S. Air Force operational fleet are 25 years old or older. A few of these will be replaced with new aircraft, but many are expected to remain in service an additional 25 years or more. This book provides a strategy to address the technical needs and priorities associated with the Air Force's aging airframe structures. It includes a detailed summary of the structural status of the aging force, identification of key technical issues, recommendations for near-term engineering and management actions, and prioritized near-term and long-term research recommendations.




Materials and Manufacturing Capabilities for Sustaining Defense Systems


Book Description

The Standing Committee on Defense Materials Manufacturing and Infrastructure (DMMI) conducted a workshop on July 23-24, 2012, to share information and gather perspectives on issues concerning Materials and Manufacturing Capabilities for Sustaining Defense Systems. This workshop, held at the headquarters building of the National Academies, 2101 Constitution Avenue N.W., Washington D.C., was conducted according to the procedures of the National Research Council (NRC) for a convening activity. That is, all workshop participants-including presenters, members of the DMMI standing committee, Reliance 21, invited guests, and visitors-spoke as individuals, and no overall findings, conclusions, or recommendations were developed during or as a result of the workshop. All statements and views summarized in this publication are attributable only to those individuals who expressed them. It is worth noting that the sponsor, Reliance 21, is a Department of Defense group of professionals that was established to enable the DOD science and technology (S&T) community to work together to enhance Defense S&T programs, eliminate unwarranted duplication, and strengthen cooperation among the military services and other DOD agencies. The DMMI standing committee named a workshop planning group to develop the workshop agenda and decide on invited guests and presenters, in accordance with the statement of task approved by the Governing Board of the NRC. The planning group also consulted with the Reliance 21 materials and processing community of interest. The presentations and discussions during the workshop are summarized sequentially in the main part of this report. As an aid to readers, nine themes have been identified by the author that recurred in multiple presentations and discussions. Materials and Manufacturing Capabilities for Sustaining Defense Systems: Summary of a Workshop explains these nine themes and summarizes the two day workshop.




Challenges and Issues with the Further Aging of U.S. Air Force Aircraft


Book Description

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.




Zero-Sustainment Aircraft for the U.S. Air Force


Book Description

Overall Air Force weapon system sustainment (WSS) costs are growing at more than 4 percent per year, while budgets have remained essentially flat. The cost growth is due partly to aging of the aircraft fleet, and partly to the cost of supporting higher-performance aircraft and new capabilities provided by more complex and sophisticated systems, such as the latest intelligence, surveillance, and reconnaissance (ISR) platforms. Furthermore, the expectation for the foreseeable future is that sustainment budgets are likely to decrease, so that the gap between budgets and sustainment needs will likely continue to grow wider. Most observers accept that the Air Force will have to adopt new approaches to WSS if it is going to address this problem and remain capable of carrying out its missions. In this context, the original intent of this 3-day workshop was to focus on ways that science and technology (S&T) could help the Air Force reduce sustainment costs. However, as the workshop evolved, the discussions focused more and more on Air Force leadership, management authority, and culture as the more critical factors that need to change in order to solve sustainment problems. Many participants felt that while S&T investments could certainly help-particularly if applied in the early stages ("to the left") of the product life cycle-adopting a transformational management approach that defines the user-driven goals of the enterprise, empowers people to achieve them, and holds them accountable, down to the shop level. Several workshop participants urged Air Force leaders to start the process now, even though it will take years to percolate down through the entire organization. These sustainment concerns are not new and have been studied extensively, including recent reports from the National Research Council's Air Force Studies Board and the Air Force Scientific Advisory Board.




Examination of the U.S. Air Force's Aircraft Sustainment Needs in the Future and Its Strategy to Meet Those Needs


Book Description

The ability of the United States Air Force (USAF) to keep its aircraft operating at an acceptable operational tempo, in wartime and in peacetime, has been important to the Air Force since its inception. This is a much larger issue for the Air Force today, having effectively been at war for 20 years, with its aircraft becoming increasingly more expensive to operate and maintain and with military budgets certain to further decrease. The enormously complex Air Force weapon system sustainment enterprise is currently constrained on many sides by laws, policies, regulations and procedures, relationships, and organizational issues emanating from Congress, the Department of Defense (DoD), and the Air Force itself. Against the back-drop of these stark realities, the Air Force requested the National Research Council (NRC) of the National Academies, under the auspices of the Air Force Studies Board to conduct and in-depth assessment of current and future Air Force weapon system sustainment initiatives and recommended future courses of action for consideration by the Air Force. Examination of the U.S. Air Force's Aircraft Sustainment Needs in the Future and Its Strategy to Meet Those Needs addresses the following topics: Assess current sustainment investments, infrastructure, and processes for adequacy in sustaining aging legacy systems and their support equipment. Determine if any modifications in policy are required and, if so, identify them and make recommendations for changes in Air Force regulations, policies, and strategies to accomplish the sustainment goals of the Air Force. Determine if any modifications in technology efforts are required and, if so, identify them and make recommendations regarding the technology efforts that should be pursued because they could make positive impacts on the sustainment of the current and future systems and equipment of the Air Force. Determine if the Air Logistics Centers have the necessary resources (funding, manpower, skill sets, and technologies) and are equipped and organized to sustain legacy systems and equipment and the Air Force of tomorrow. Identify and make recommendations regarding incorporating sustainability into future aircraft designs.




Red Is Good: Transformational Changes for US Air Force Aircraft Maintenance


Book Description

Over the last two decades, the Air Force's fleet of aircraft has shrunk 40 percent, while the average inventory age has increased from eight years in 1973 to a projected 26.5 years by 2012. Concurrently, this smaller, older fleet has been tasked with 2.3 million flight hours per year since the end of Operation Desert Storm. In an environment of flat bud-gets, limited manpower, and an aging, shrinking fleet, the Air Force seeks cultural transformations to remain the world's premier air, space, and cyberspace force. The trans-formation initiative Air Force Smart Operations for the 21st Century (AFSO21) was designed to increase productivity, responsiveness, and efficiency, thus improving equipment readiness, reliability, and availability. Given the mixed results of past transformation efforts, has AFSO21 achieved the desired effects? Col Paul "P. J." McAneny offers an analysis focused on aircraft maintenance but applicable to the entire force and recommends cultural changes to support lasting transformation. He ex-amines the impact of metrics on transformation and evaluates the USAF aircraft maintenance culture. He asks several questions: Can focused metrics precede cultural change? Does the aircraft maintenance community support a Red Is Good culture, in which metrics are used to illuminate problems rather than measure success or failure? If so, is the community a true learning organization that can maximize its impact through continuous process-improvement initiatives? The answers lead Colonel McAneny to recommend several Air Force-level changes to meet long-term aircraft readiness and reliability targets.
