Unleaded Aviation Fuel: Assessing Stakeholder Perceptions And Preparing An Organization For Change, Ryan Guthridge, Nicholas D. Wilson, Brandon Wild

Journal of Aviation Technology and Engineering

Since the Clean Air Act of 1996 banned the use of leaded fuel for automotive applications, leaded aviation gasoline (AVGAS) has become one of the leading sources of lead pollution in the nation due to the volume of AVGAS consumed in general aviation applications (GAMA, 2019). The Federal Aviation Administration has recently recognized this concern with the establishment of the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative, which was formally established in February 2022 to foster an important campaign to research and inform the general aviation community on the process for transitioning to unleaded AVGAS. This essay seeks to inform …

Efficacy Of Virtual Reality-Based Simulations In Training Aviation Maintenance Technicians On Maintenance Procedures, Gayatri Anoop

All Theses

The COVID-19 pandemic forced institutions of higher education (IHEs) to halt in-person classes and transition to online platforms. Given the intricate process of adapting hands-on experiments to the online environment, this transition seemed particularly challenging for Science, Technology, Engineering, Mathematics, and Medicine (STEMM) labs. The abrupt nature of this transition added to the difficulties, given that the IHEs were inadequately prepared for seamless continuity during the pandemic. In the first phase of this project, a literature review was conducted to understand the impact of COVID-19 pandemic on education. Specifically, the review explored the challenges that institutions of higher education faced, …

Assessing Past Airworthiness Directives And How Safety Management Systems May Benefit Aviation Product Design And Manufacturing, Damon Lercel, Manoj Patankar, Richard Steckel

Journal of Aviation/Aerospace Education & Research

The European Union Aviation Safety Agency (EASA) continues to promulgate Safety Management Systems (SMS) across aviation organizations when it recently issued SMS requirements for EASA certificated Part 145 maintenance, repair and overhaul (MRO) organizations and Part 21 Design & Manufacturing (D&M) organizations. Currently, the Federal Aviation Administration (FAA) has no such rule in place for these U.S.-based organizations, which may challenge those doing business in countries where EASA policies apply. Given that a majority of the United States’ D&M and MRO population is made up of smaller organizations, it is likely a U.S. SMS regulation will require justification of the …

Qualitative Findings From The Practice Of Outsourcing By The Aviation Technical Services Industry In Northern Europe: Comparison With Literature, Jukka Holkeri

Journal of Aviation Technology and Engineering

The outsourcing of maintenance and other technical services is a trend in both military and civil aviation. This article uses input from real outsourcing cases in Northern Europe to verify previous literature findings and to introduce new viewpoints to fill an identified research gap.

Interviews of deeply involved individuals from six cases were selected and analyzed using the Delphi method. The findings were synthesized using a framework that articulates contexts, observed outcomes, and generative mechanisms.

Many of the key literature findings were verified by this case analysis, but there were also some contradictions and new observations that had not been …

Performance Results Of Using Waste Vegetable Oil Based Biodiesel Fuel In A Turboshaft Gas Turboshaft Engine, Donald Bartlett 5218591, Blaine M. Heisner

Journal of Applied Sciences and Arts

Biodiesel is a renewable fuel product made from triglycerides with properties similar to petroleum-based fuel. It is blended with various petroleum fractions to produce automotive and transportation fuels and is not typically utilized as a standalone fuel. Biodiesel can be manufactured from various feedstock including straight vegetable oils (SVO), waste vegetable oils (WVO), and animal fats. Although most U.S. biodiesel is made from SVO, using WVO feedstock is a much cheaper option. As biodiesel fuel offers certain advantages over petroleum based fuels, the aviation industry has gradually advanced the use of the fuel in gas turbine engines. However, increased viscosity …

Toward GemeinschaftsgefüHl: Exploring Subordinate And Manager Perceptions Of Trust And Perceptions Regarding Behavioral Change Potential, Bobby G. Martin

Publications

In this qualitative, phenomenological study, Maslow‘s Eupsychian theory was used as the guiding framework for exploring the perceptions of trust and the behavioral change potential of subordinates (includes frontline supervisors) and managers (excludes frontline supervisors) within selected aviation maintenance organizations in Arizona. The problem addressed in the study was the growing concern that managers willfully mistreated subordinates, which led to decreased trust, motivation, and productivity. A combined representative sample of 10 maintenance technicians and frontline supervisors was purposively selected from the production lines of a large commercial aviation repair and overhaul station located in Arizona. An additional combined representative sample …

The Effect Of Shift Turnover Strategy And Time Pressure On Aviation Maintenance Technician Performance, William R. Warren

Doctoral Dissertations and Master's Theses

Aviation maintenance technicians (AMTs) provide the technical and applied knowledge required to maintain airworthiness in aircraft. In commercial aviation, maintenance tasks are performed across multiple shifts. When AMTs share a maintenance task between shifts, the shift turnover strategy used may determine if information is effectively transferred between AMTs. Ineffective shift turnover strategies are a contributing factor in many aviation accidents and incidents. Additionally, time constraints on certain maintenance tasks may cause AMTs to commit error when performing a task. The present study examined the effect of shift turnover strategy (face-to-face or written) and time pressure on error capture, accuracy, and …

Mandatory Certification Of Aviation Line Service Technicians: A Question Of Formal Or Informal Training, Jeffrey S. Lewis

Master's Theses - Daytona Beach

Accidents and incidents are created by improperly trained aviation line service technicians. To reduce accidents and incidents associated with improperly trained line service personnel, a mandatory certification plan should be developed. This study utilized the procedures established for the descriptive research method. The researcher gathered data with a self constructed questionnaire, from 72 separate sources of the 120 solicited. All relevant data was analyzed to decide if the research hypothesis could be accepted. The researcher anticipated that statistical evidence would support the research hypothesis, that structured formal training procedures would reveal a significant reduction in the number of accidents and …
