This Advisory Circular (AC) describes acceptable means of compliance with requirements relating to the development of a flight crew fatigue management system in accordance with Parts 121, 125, and 135.
This AC relates specifically to Subpart K of Parts 121, 125, and 135.
Revision 2 removed the exception in the last paragraph of the General Restrictions section on Page 4 as the references to flights made “in the interests of safety or health of any person” is a different (and lower) test than that required by S13A of the Act for breaching the provisions of the Act or Rules made under the Act.
Note: In accordance with the Health and Safety at Work Act 2015(external link) , organisations are required to make sure their operation is safe (so far as is reasonably practicable), which includes minimising the risk of fatigue for all workers performing safety-related duties. CAA Advisory Circular AC119-2 Air Operations – Fatigue of Flight Crew provides an example for various types of air operations. Further information and guidance can be found on the CAA Fatigue Risk Management webpage.
On 31 March 2022, a Version History was added to this AC in line with the format for other ACs.
