An Analysis Of Aircraft Maintenance Leading Indicator Metrics To Unit-Level Aircraft Availability Rates, William C. Hardy
An Analysis Of Aircraft Maintenance Leading Indicator Metrics To Unit-Level Aircraft Availability Rates, William C. Hardy
Theses and Dissertations
The purpose of this research is to improve the usefulness of data that is already collected within aircraft maintenance organizations to better identify trends, and outliers, and possibly better explain relationships between leading and lagging indicator metrics. Specifically, this graduate research paper sought to answer two research questions addressing what aircraft maintenance metrics significantly impact aircraft availability, and how to measure those to understand which metrics impact aircraft availability most. The research questions were answered through a comprehensive literature review, and the use of multiple linear regression analysis on data from two specific aircraft maintenance organizations from the same location. …
Explaining Weapon System Sustainment's Impact To Aircraft Availability, Michael D. Ingram
Explaining Weapon System Sustainment's Impact To Aircraft Availability, Michael D. Ingram
Theses and Dissertations
This research focused on understanding the phenomena behind the cost growth of Weapon System Sustainment (WSS) and the simultaneous degradation in USAF aircraft system availability. The primary modelling technique used was Ordinary Least Squares (OLS) while incorporating temporal effect. Other studies have looked at cost factors related to the Flying Hour Program, flying conditions and age. This study found empirical relationships between each of the four WSS business processes and the lead time in months it takes to realize improvements in system aircraft availability.
Common Support Equipment And Its Impact On Aircraft Availability, Jason M. Leighton
Common Support Equipment And Its Impact On Aircraft Availability, Jason M. Leighton
Theses and Dissertations
The ability of military aircraft maintenance personnel to prepare aircraft for flight depends not only on the technical ability and availability of replacement parts, but also on access to serviceable support equipment. While the general relationship between support equipment failures and aircraft availability is understood, the struggle to quantify that relationship makes targeted support equipment replacement or quantity authorization increases difficult. Tight budgets and aging equipment further complicate the task of keeping serviceable support equipment assets in the hands of maintainers. We identify key pieces of support equipment which may affect aircraft availability and other metrics and investigate the associated …
