Work Hours of Aircraft Maintenance Personnel, by Simon Folkard D.Sc.: The report by Professor Simon Folkard on Work Hours of Aircraft Maintenance Personnel was issued on July 16th 2002. This report contains the results of an independent study carried out by Professor Folkard and funded by the UK Civil Aviation Authority (CAA). The work was commissioned largely in response to concerns expressed via the Confidential Human Factors Incident Reporting Programme (CHIRP) that excessive hours worked by some maintenance personnel posed an aviation safety risk.

The report is a scientific paper concerning the subject of work hours and fatigue. Please note that the recommendations are those of the author, Professor Folkard, and do not at this stage constitute formal, or informal, CAA policy regarding duty time limitations for maintenance personnel. The CAA is reviewing the paper and its conclusions with a view to further action which will be discussed with industry. In due course the paper may be issued as a CAA paper.
