Study Notes

Aviation accidents can be caused or contributed to by human factors, with at least 80% of maintenance-related incidents involving human errors.
Aviation maintenance is crucial for safety but mistakes made by Aviation Maintenance Technicians (AMTs) can be difficult to detect and can lead to injuries, wasted time, and accidents.
AMTs face unique challenges as they often work in adverse conditions, including evening or early morning hours, confined spaces, and extreme temperatures.
Maintenance errors can include incorrectly installed parts, missing parts, or missed checks.
AMTs spend more time preparing for a task than actually carrying it out, and proper documentation is essential.
Human factors are crucial in aviation maintenance as they can impact worker performance and safety.
Aging and abnormal medical conditions are factors that can affect AMTs; vision loss and obesity can compromise their ability to perform tasks and lead to latent errors.
PEAR model is a tool used in aviation maintenance to identify human factors and helps in mitigating the risk of errors.
PEAR stands for People, Environment, Actions, and Resources.
People: Refers to the humans in the system, including their physical and cognitive capabilities, communication styles, decision-making, and leadership skills.
Environment: Refers to both the physical environment and the organizational environment, including lighting, temperature, noise level, time of day, supervision, and existing organizational norms.
Actions: Refers to the tasks performed by AMTs and the potential for errors.
Resources: Refers to the necessary tools, equipment, and information to complete the job.
PEAR model was developed to help aviation maintenance personnel identify human factors and relate to tasks and conditions within the maintenance environment.
The PEAR model covers both technical and human factors considerations, including training, fatigue, stress, and motivations.
