Note: The occupational safety and health of flight crewmembers (i.e., pilot, flight engineer, flight navigator) are under the jurisdiction of the Federal Aviation Administration (FAA) and not covered by OSHA standards while they are on aircraft in operation. However, under a policy statement issued by FAA and a Memorandum of Understanding (MOU) between the FAA and OSHA, Occupational Safety and Health Standards for Aircraft Cabin Crewmembers, the other aircraft cabin crewmembers are covered by OSHA's Bloodborne Pathogens (29 CFR 1910.1030), Noise, (29 CFR 1910.95) and Hazard Communication (29 CFR 1910.1200) standards while they are on aircraft in operation (which occurs from the time the aircraft is first boarded by a crewmember, preparatory to a flight, to the time the last crewmember leaves the aircraft after completion of that flight, including stops on the ground during which at least one crewmember remains on the aircraft, even if the engines are shut down). These include flight attendants, workers assigned to clean and restock the cabin, and other workers assigned to perform duty in an aircraft cabin when the aircraft is in operation.
