A case study of factors impacting fatigue in aircraft maintenance technicians (AMT)

Abstract

Purpose: When we talk about "fatigue" in aviation maintenance, it's a term that is widely used but can have different meanings depending on the situation. In the context of maintenance personnel, "fatigue" can encompass physical tiredness, emotional exhaustion, the decline in skills from performing mentally demanding tasks over a long period, chronic fatigue due to insufficient rest, and even the unmet need for sleep. So, it's crucial to consider the specific context of aviation maintenance when discussing fatigue and its implications. Design: The research for this study is conducted by gathering information from a variety of sources, including case studies, journal articles, magazines, books, and internet searches. These secondary sources offer valuable insights that contribute to the overall understanding of the topic. Findings: The study investigates factors contributing to fatigue in Aviation Maintenance Technicians (AMTs). Findings reveal that irregular and extended working hours, compounded by unpredictable schedules, contribute to persistent fatigue. High workload and time pressure amplify mental and physical strain, posing risks to safety. Sleep disruption and circadian rhythm disturbances adversely affect cognitive abilities. Environmental factors, including noise and harsh weather conditions, contribute to overall fatigue. Cumulative fatigue resulting from consecutive workdays without sufficient recovery time raises safety concerns. Organizational culture and support significantly impact AMT's experiences of fatigue, emphasizing the importance of a supportive work environment. Originality Value: This study takes a distinctive approach to examining the complex aspects of fatigue in aviation maintenance. It provides a comprehensive understanding by considering various factors that contribute to fatigue and their potential impact.
