Memories....let me think! Astar also had tail rotor blade strikes on tail boom, servo transparency is still a reality, Bell 407 tail rotor blade strikes on tail boom also, Allison C-28 engine issues in Longrangers (before the C-30 came out), FH100 short shaft failures, Hughes 369D main rotor head blade grip failures, Bell 214 main rotor blade failures (metal blades), (anyone care to add to the list?)....and there are many, many, more where the manufacturer's had to issue countless A.D.'s, S.B.'s and A.W.D's to rectify design shortcomings......point is, Robinson is far from the only one....
