GM1 NCC.OP.157 Refuelling with the engine(s) and/or rotors turning — helicopters ED Decision 2022/005/R RISK ASSESSMENT The risk assessment should explain why it is not practical to refuel with the engine(s) and rotors stopped, identify any additional hazards, and describe how the additional risks are controlled. Helicopter offshore operations (HOFO) are typical operations where the benefits should outweigh the risks if mitigation measures are taken. Guidance on safe refuelling practices is contained in ICAO Doc 9137 Airport Services Manual, Parts 1 and 8. The operator’s risk assessment may include, but not be limited to, the following risks, hazards and mitigation measures: (a) risk related to refuelling with rotors turning; (b) risk related to the shutting down of the engines, including the risk of failures during start-up; (c) environmental conditions, such as wind limitations, displacement of exhaust gases, and blade sailing; (d) risk related to human factors and fatigue management, especially for single-pilot operations for long periods of time; (e) risk mitigation, such as the safety features of the fuel installation, rescue and firefighting (RFF) capability, number of personnel members available, ease of emergency evacuation of the helicopter, etc.; (f) assessment of the use of radio transmitting equipment; (g) determination of the use of passenger seat belts; (h) review of the portable electronic device (PED) policy; and (i) if passengers are to disembark, consideration of their disembarking before rather than after the refuelling; and (j) if passengers are to embark, consideration of their embarking after rather than before the refuelling.
