Aircraft maintenance is a fundamental and necessary element in any aviation operation. In order to be considered safe and airworthy, operators must be diligent in the way aircraft are maintained and how employees are performing. A safety management system (SMS) is an organized approach by management to include every employee of a company that standardizes the procedures a company will follow to improve safety. The structure of SMS was designed by the International Civil Aviation Organization in order to be standardized across different countries and types of operations. Currently, only part 121 U.S. commercial airlines are mandated by the Federal …

Engine Light Repair Shop Evaluation For A Brazilian Airline, Gustavo Henrique Melhado Trevilatto, Marcelo Teodoro Miranda

Graduate Student Works

The maintenance cost of a commercial aircraft comprises airframe, components, and engines. The most expensive of them are engines, which may represent up to 60% of an aircraft cost, and therefore will have a significant impact on any airline finance. As a result, engine fleet maintenance management is crucial for any airline sustainability. Apart from heavy maintenance where life limited parts are replaced and its performance restored, aircraft engines are often required to come off wing for light repair due to operational issues like foreign object damage, high oil consumption, and vibration issues. In other cases, even though being operational, …

Small Unmanned Aircraft Systems Flight Training Programs Through The Lens Of A Traditional Flight Training University, David Thirtyacre, C. Woodyard

Publications

According to CFR 14 Part 107, an RPC is issued strictly on the results of the Federal Aviation Administration’s (FAA) knowledge test and background security check. This leaves commercial sUAS operators on their own to determine the training and proficiency required to fly safely and effectively. Regardless of the learning method, the question becomes, what knowledge and maneuvers should be learned, and to what proficiency level? This paper explores specific knowledge and skills which should be mandatory for all sUAS commercial pilots and recommends a probation period to gain experience before receiving an unrestricted RPC.
