What is the maximum allowable 24-hour duty day length under 14 CFR 135.267?

Explanation:
The maximum length of a duty day within any 24-hour period for Part 135 operations is fourteen hours. This limit is set to help manage crew fatigue by capping all on-duty time—preflight, flight time, and postflight duties—that occur in a single 24-hour window. If a flight schedule would require more than fourteen hours on duty, the operation must be split into additional duty periods with proper rest or additional crewmembers to stay within the limit.
