Study Notes
Human Factors in Aviation Maintenance
- Human factors science is a multidisciplinary field combining psychology, engineering, design, statistics, and anthropometry. It studies human capabilities and applies this understanding to design, development, and deployment of systems.
- Elements of human factors in aviation maintenance: error management, ergonomics, and training.
- Maintenance Error Management: determining why maintenance errors occur and creating solutions to prevent future errors.
- Ergonomics: applying ergonomic principles to the maintenance work environment.
Human Factors Disciplines
- Clinical psychology: focuses on mental well-being, coping mechanisms, and managing stress.
- Experimental psychology: studies basic behavioral processes in a laboratory setting.
- Anthropometrics: studies human body dimensions and capabilities. Vitruvian Man by Leonardo da Vinci is an early example of anthropometry.
- Computer Science: studies the theoretical foundations of information and computation, and practical techniques for implementation.
- Cognitive Science: interdisciplinary study of minds as information processors.
- Safety Engineering: ensures life-critical systems function even in the event of component failure. OSHA is an example of a safety organization.
- Medical Science: science and art of healing, encompassing prevention and treatment of illness.
- Educational Psychology: studies how people learn and designs methods and materials for education at all ages.
- Organizational Psychology: studies the relationship between people and work, including organizational structure and change.
- Industrial Engineering: organized approach to studying work. Frank and Lillian Gilbreth, pioneers in industrial engineering, developed the concept of call backs in communication, which is used in aviation today. They also researched fatigue.
Wright Brothers and Human Factors
- The Wright brothers made significant contributions to human factors in aviation.
- They introduced the first practical human interactive controls for aircraft pitch, roll, and yaw.
- Orville Wright was the first aviator to use a seat belt and introduced a rudder boost/trim control.
PEAR Model
- People: addresses physical, physiological, psychological, and psychosocial factors of personnel performing maintenance.
- Environment: refers to both the physical environment (temperature, humidity, lighting, noise, cleanliness, workspace design) and the organizational environment (cooperation, communication, shared values, mutual respect, company culture).
- Actions: analyzing actions required for safe and efficient maintenance task completion. Job Task Analysis (JTA) is used to identify required skills, knowledge, and attitudes for each task.
- Resources: anything needed to complete a task, including protective clothing, tools, parts, and documentation.
Dirty Dozen
- Lack of Communication: insufficient communication about a task can lead to errors.
- Complacency: overconfidence and lack of awareness can lead to complacency.
- Lack of Knowledge: insufficient training or information can lead to errors.
- Distractions: anything that takes your attention away from the task can cause errors.
- Lack of Teamwork: inability to collaborate effectively can impact task completion.
- Fatigue: physical or mental exhaustion can affect performance.
- Lack of Resources: insufficient resources (personnel, equipment, time, etc.) can impede task completion.
- Pressure: unrealistic expectations or perceived pressure can lead to errors.
- Lack of Assertiveness: failure to voice concerns or document issues can cause errors.
- Stress: physical, chemical, or emotional factors causing tension can impact performance.
- Lack of Awareness: not recognizing or understanding a situation can lead to errors.
- Norms: unwritten rules or expected behaviors within an organization.
Maintenance Error Decision Aid (MEDA)
- MEDA is a structured process for investigating events caused by maintenance technician and/or inspector performance.
- MEDA Philosophy: focusses on analyzing why the error occurred and implementing solutions to prevent future errors.
