Crashworthiness
Hi HLC,
I agree that the Blackhawk is probably second to none for crash survivability. The MRH 90 has been certified to FAR29 standards, and I haven't seen any specs or details on what that means for crash protection. It does have crashworthy, stroking seats for all occupants.
If the wheels are up there would be little attenuation from them in the event of a crash. I know that some operators of Puma leave the wheels down for that reason. I'm afraid I don't know much else about this aspect of the aircraft. The MLG struts are quite substantial when you look at them behind the cabin wall.
