If the tail-rotor (and possibly the tail rotor gearbox) actually separate from the aircraft in flight, can the R44 sustain that from a C of G standpoint? I know that proved terminal for a Jet Ranger in scotland some years ago.
A NZ pilot in a R44 lost Tail Rotor gear box, blades etc....stabs stayed on,. flew for 20 odd minutes run it onto a grass airstriip.It can be done, just need to be lucky where it all departs
