US-FAA14 CFR 135.123

Emergency and emergency evacuation duties

Read the official rule

This regulation requires Part 135 operators to assign specific emergency duties to each required crewmember for each aircraft type they operate. The operator must ensure these assigned tasks are actually achievable in real emergency situations, including scenarios where a crewmember becomes incapacitated or cannot reach the passenger cabin (such as when cargo shifts in a combination cargo-passenger aircraft).

The assignments must cover both general emergencies and emergency evacuations. Importantly, the operator cannot simply assign duties on paper—they must verify that the tasks can be "practicably accomplished" given the aircraft configuration and potential emergency conditions.

All these emergency duty assignments must be documented in the company's operations manual. This ensures crewmembers know their specific responsibilities and can train accordingly. The regulation recognizes that effective emergency response requires advance planning that accounts for real-world complications, not just ideal conditions.
