The Impact Of Human Factors And Maintenance Documentation On Aviation Safety: An Analysis Of 15 Years Of Accident Data Through The Pear Framework, Flavio A. C. Mendonca, Natalie Zimmermann

Publications

Regardless of the type of maintenance performed on aircraft, instructions are to be used to provide the aviation technicians completing the maintenance activities with guidance on, and an outline of, the maintenance items to be performed and completed. However, the use of instructions does not guarantee the correct and proper completion of the maintenance activities as the instructions may be erroneous and/or maintenance personnel can misunderstand, misinterpret, or improperly follow the procedures outlined. Resulting maintenance errors can potentially result in aircraft accidents, as illustrated by Air Midwest Flight 5481. With the purpose of understanding how human factors associated with written …

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

Publications

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, engines …

A Comparison Of Malfunction-Related Accidents For General Aviation Aircraft Manufactured In 1970–1984 And 2000–2014, Douglas Boyd, Jochen Hinkelbein

Publications

The United States general aviation fleet is aging with aircraft manufactured 35–39 years ago representing the most prevalent group. Since older aircraft are more prone to airframe corrosion, fatigue, and brittle electrical wiring, the present study was undertaken to determine whether malfunction-related accidents for general aviation aircraft manufactured between 1970 and 1984 were elevated relative to airplanes produced more recently (2000–2014).

The NTSB aviation accident database was used to identify piston-powered airplane accidents occurring over the 2005–2014 period. Aircraft manufacture year and fleet activity data were from the FAA. Statistical analyses employed contingency tables and Poisson distributions.

The proportion of …

Maintenance Implications For Unmanned Aerial Vehicles In Remote Locations, Ian R. Mcandrew, Mark Kaintz, Andrew Carruthers

Publications

Maintenance in the aviation industry has evolved considerably since commercial and general aviation became a modern mode of transportation. ICAO has made maintenance a top priority by directing local National Aviation Authorities, NAA, to have implemented, robust and standardized training and qualifications for all maintenance personnel that work on any safety critical structure or component. There are rules, law and standards that are audited and the aviation industry is, perhaps, the most successful industry in maintaining standards and reliability. With the advent of Unmanned Aerial Vehicles, UAV, the role of maintenance is now needing to be reviewed to determine how …
