Federal Aviation Administration January 4, 2012 – Federal Register Recent Federal Regulation Documents

This rule amends the FAA's existing flight, duty and rest regulations applicable to certificate holders and their flightcrew members operating under the domestic, flag, and supplemental operations rules. The rule recognizes the universality of factors that lead to fatigue in most individuals and regulates these factors to ensure that flightcrew members in passenger operations do not accumulate dangerous amounts of fatigue. Fatigue threatens aviation safety because it increases the risk of pilot error that could lead to an accident. This risk is heightened in passenger operations because of the additional number of potentially impacted individuals. The new requirements eliminate the current distinctions between domestic, flag and supplemental passenger operations. The rule provides different requirements based on the time of day, whether an individual is acclimated to a new time zone, and the likelihood of being able to sleep under different circumstances.
