I am curious if a rotorcraft could be suspended from rotorhead for an extended period of time.

I am curious about R22 and R44. I believe I have seen them in the shop lifted up from the 2 holes in the rotor head.

I am also curious if all helicopters have mount/lift points in the rotor head like an MD500C. Would you be able to do the same?

Or are you better lifting from the skids for a longer term lifting?

    $\begingroup$ I‘m pretty sure all helicopters are suspended from their rotors when flying. Seems to work for most of them. $\endgroup$

    $\begingroup$ @JustSid Bearings can be rated for lower static loads than dynamic loads - when flying, your rotor is definitely not static. $\endgroup$

    $\begingroup$ And if you're looking for the lift points, best to consult the specific aircraft type maintenance manual to find out precisely what to do and how to do it. $\endgroup$ Sep 17 '17 at 20:48
  • $\begingroup$ I was just in the R44 and can confirm, it is lifted via the rotors $\endgroup$

Yes, but you better know what the heck you are doing. :) Whether an individual helicopter can be lifted this way is a different question. You'd have to look at the maintenance manual for the individual aircraft for the answer.

CH-47 being lifted onto a ship by crane.

    $\begingroup$ Note the crossbar: The side loads of a crossbar-less hoist would definitely crush the rotor mounts. $\endgroup$ Sep 29 '17 at 23:48

    $\begingroup$ That comment applies to just about everywhere. And is often enough neglected … $\endgroup$ Sep 30 '17 at 9:30
