Helipilot
The 139 tail section is good for a 45 knot crosswind and I'm pretty sure that the flight loads involved far exceed that experienced when ground taxiing. If there were any doubts about that then EASA would have required an amendment to the RFM limitations. Let's not get carried away with one event that is now well documented and not representative of a serviceable airframe.
The 139 is unusual insofar as the RFM required the pilot to avoid the use of in-turn cyclic and not to apply cyclic laterally except to deal with a crosswind.
