"Human Factors"

"Human Factors Certificates are required to certify work on EU/EASA aircraft.

You need to show you have attended and passed a course in the effects and causes of Human Factors in Aircraft Maintenance and Inspections.

Any-one who is involved in aircraft maintenance as part of an EASA Part 145 appproved organisation has to receive some level of HF training."

ok thank you
