rfm is the rotor flight manual.. how to operate the helicopter..... nothing to do with maintenance .... you need to check the maintenance manuals for the engine and helicopter.....
Yes, but as a pilot, or owner, who reads the maintenance manual... I would say that this very much falls under how to operate a helicopter if it must be operated every 7 days. Thats not very long. I had never heard of this before but don't fly the 120. Are most 120 pilots/owners aware of this? Thanks for raising it...
