Human Factors plays a crucial role in Maintenance Mistakes and system solutions in aerospace engineering.
Human Factors is not just about people: it is also about systems. Yet aircraft’s becoming increasingly reliable,
Human errors – powerful forces affecting the quality of maintenance, produced by:
The BASI analysis of maintenance incident reports found that for incidents which had airworthiness implications, the most common factors in the work area at the time of the incident were:
Older, experienced workers will sometimes develop their own practices, which may be different from the approved procedures.
In a recent survey, senior US maintenance mechanics were asked to describe the most challenging part of their job. Their most common answer was ‘human relations or dealing with people’s Performing in a team requires more than technical know-how, and we often overlook the need to develop these important communication and people skills.
pressure is a fact of life for maintenance engineers.
engineers faced with real or self-imposed time pressures will be tempted to take shortcuts to get an aircraft back into service more quickly.
By necessity, these error-capturing safeguards occur at the end of jobs, at exactly the time when pressures to get the aircraft back into service are likely to be greatest.
In the recent BASI survey, 32% of mechanics reported that there had been an occasion when they had not done a required functional check because of a lack of time. At the time, such a decision may have seemed safe and reasonable; however, decisions made under pressure do not always stand the test of hindsight.
Younger personnel need to know about the traps lying in wait for them, yet too often they are allowed to discover these for themselves.
The great benefit of human factors training in aerospace engineering is not only that people change, but that people can see the opportunities to change the systems in which they work. For this reason, managers, who have the most power to change things, should not be excluded from human factors training.
