Practicaly we all turn rotors by hand and gently does it is the way forward.

I am deviating from B412 info here but for the benefit of ericferret,

FYI RE: AW139

Straight from the IETP (Maintenance Manual)

CAUTION
Do not push or pull the tail rotor blades to turn the tail rotor. It is easy to cause damage to the tail rotor blades if you push or pull them. Turn the tail rotor driveshaft or the main rotor to set the tail rotor to the necessary position.

I see the maintenance industry as a whole do this on the AW139...yet it clearly states not to do in the IETP.

Anyway-just for your info
