Reducing Human Error in Aircraft Maintenance Operations with the Maintenance Error Decision Aid (MEDA)

Abstract

The Maintenance Error Decision Aid (MEDA) is an event-driven tool that assists a maintenance investigator to identify contributing factors and corrective actions that will prevent airplanes from being dispatched with error-induced discrepancies. MEDA attempts to influence the user to think differently about how he views and investigates maintenance error by supporting a human-centered, error investigation.

Human error in maintenance: a review

“…Allen and Rankin (1995) in their article discussed the Maintenance Error Decision Aid (MEDA) Tool and field test evaluation. In another article, Hibit and Marx (1994) anticipated that, by improving the analysis of individual events through tools such as MEDA, people can begin to better understand those factors underlying human error in maintenance so that future system performance can be methodically improved in better safety, greater maintenance system reliability, and economic efficiencies gained through error reduction. Nelson et al (1998) presented structured methods of human error analysis developed and applied at Idhao National Engineering and Environmental Laboratory (INEEL) to identify potential human errors, assess their effect on system performance, and develop strategies to prevent the occurrences of errors or mitigate their consequences.…”

“…Manwaring et al's (1998) study showed that by adhering to existing regulations and manufacturer recommendations, and by implementing improved training and frequent maintenance, helicopter external load operations become safer. Shepherd (1997) presented a discussion of factors such as evaluation of simplified English, technician teaming and advanced technology, which influence the Allen and Marx (1999); Allen and Rankin (1995); Amalberti and Wioland (1997); ; Braithwaite (1997); Ciavarelli (1997); Drury (1991); Endsley and Robertson (2000); Ford (1997); Fotos (1991); Graeber and Marx (1993); Havard (1995); Hibit and Marx (1994); Hobbs and Robertson (1995); Hobbs and Williamson (1995); Ivaturi et al (1995); Kania (1997); Koli et al (1998); Latorell and Prabhu (2000); McGrath ( 1999 (1996); Rankin et al (2000); Reason (1997aReason ( , b, 2000; Shepherd (1991Shepherd ( , 1997; Shepherd and Johnson (1995); Shepherd and Kraus (1997); Strauch and Sandler (1984); Taylor (2000a, b); Walter (2000); Wanders (1985); Wenner and Drury (2000) 2…”

A Study of Applying Fuzzy Theory in Simulation-Based Education

“…Personnel should also have excellent understanding of the work they are engaged in. They should be capable of understanding relevant meaning, function, and possible impact on the things they observe [10]. SA for pilots includes understanding all relevant information in a flight environment and predicting what could occur to affect operations [5].…”

“…At the second stage of this study, the collected and analyzed questionnaire in this study obtained a fuzzy value of the "Competency and Scenario." This study used Equation (10) to conduct defuzzication of the values and converted those values into definite values. Then, we may understand the "Competency and Scenario's" weight of military helicopter EBT's decision process.…”

“…We've discovered that maintenance errors cause Maintenance failures cost the US industry more than 2 billion a year, according to 15% of air carrier accidents. "Human factors" coverages a huge scope of exercises, and they encroach on all that AMTs do at work, from discussing successfully with partners to guaranteeing that they have sufficient lighting that is precise and effective [6] [7] [8].…”
