Maybe we all need some “thought
control?”
What is in it for you?
Most of our errors are in thinking rather than lack of knowledge.
Think about your actions that may lead to error.
Save time and money?
Apply principles to life.

Philosophy of Error Reporting (Boeing-MEDA)
• Staff do not make errors on purpose
• Maintenance errors are made because of a series of related contributing factors
• Most of the contributing factors are part of maintenance organization processes and can be changed Slide provided by Boeing, Dr. Bill Rankin
![Page 42: Federal Aviation Human Factors and Your Job Administration ... · Human Factors Spectacles.

More MEDA Philosophy
• Maintenance program must be viewed as a
system, where the mechanic is one part of the
system
• Addressing lower level events helps prevent
more serious events
