attendants, maintenance technicians, and others.11 There was limited information available in the reports to determine the degree to which commuting was a factor in the reported incidents. Also, since these reports are voluntarily submitted, in some cases to gain immunity from punishment, it is not clear the extent to which these reports are representative of the experiences of the entire Part 121 pilot population. The committee did not find that these data were useful in the context of the committee’s charge, and these data are not discussed in the report.

CONCLUSION: There is potential for pilots to become fatigued from commuting. However, there is insufficient evidence to determine the extent to which pilot commuting has been a safety risk in part because little is known about specific pilot commuting practices and in part because the safety checks, balances, and redundancies in the aviation system may mitigate the consequences of pilot fatigue.
