Study Notes
Aviation maintenance and human factors
- Human factors issues in aviation maintenance have gained attention due to accidents like the Aloha Airlines 737 incident in 1988 and the BAC 1-11 windscreen incident in 1990.
- Human factors in aviation maintenance involve the study of human capabilities and limitations in the workplace.
- The study encompasses the interaction of maintenance personnel, the equipment they use, the procedures they follow, and the environmental conditions.
- The aim is to optimize the relationship between personnel and systems to improve safety, efficiency, and well-being.
- The work often involves fault diagnosis and problem-solving, which can be stressful, particularly in time-sensitive situations like aircraft maintenance at the gate.
- Maintenance personnel often face unique sources of stress because of their work's long-term impact on safety.
- Maintenance errors can have a lasting impact, extending to the months or years after completion, unlike many errors made by pilots or air traffic controllers.
- Maintenance personnel's unique exposure to the consequences of their work can lead to mental health implications, as evidenced by incidents where maintenance personnel have taken their own lives after aircraft accidents attributed to maintenance errors.
- Maintenance professionals in aviation are similar to doctors and surgeons in that they are responsible for the function and safety of a complex, vital system.
- Maintenance tasks are categorized as scheduled and unscheduled.
- Scheduled maintenance tasks, usually preventative, are often familiar routines for experienced personnel, minimizing the risk of errors due to a lack of knowledge or skills.
- Unscheduled maintenance tasks are more complex, requiring problem-solving and diagnostic skills.
- Human error plays a dominant role in civil aircraft accidents.
- Pilot error is a significant factor in aircraft accidents.
-
Common pilot errors include:
- Deviations from basic operational procedures.
- Inadequate cross-checks by the second crew member.
- Insufficient or incorrect weather information.
- Improper crew response during abnormal conditions.
- Ignoring crew inputs.
- Failure of the approach guidance.
- Maintenance and inspection deficiencies often contribute to aviation incidents.
- Maintenance errors can result from a combination of factors, including staff shortages, time pressures, and inadequate training.
- The Japan Airlines 747 crash in 1985 highlights the consequences of a poorly executed repair, leading to a fatigue fracture in the aircraft’s rear pressure bulkhead.
- The incident involved a critical repair, where most of the vertical stabiliser and rudder were separated due to the escaping air from the rear pressure bulkhead.
- An Aloha Airlines 737 incident in 1988 was caused by a failure to detect significant disbonding and fatigue damage, leading to the separation of a part of the aircraft's fuselage.
-
Factors contributing to these incidents include:
- Staff shortages
- Time pressures
- Poor communication
- Inadequate training
- Lack of proper procedures.
- The importance of human factor considerations in aviation maintenance has been highlighted by investigating these incidents.
- The incidents emphasize the need for improved training, procedures, and communication in aviation maintenance to minimize human error and improve safety.
