Sounds as if the Lynx has a similar accessory drive system to the old Wessex 2 and 5, which caught out a number of people over the years. Jolly good idea though and I wish a few more civil twins had it.
As for the EC135, I wonder if it landed on an unstable offshore helideck and was rotors running because of strong and gusting winds, if it would be possible for the blades to strike someone inside the rotor disc if the pilot made a control input to stop his aircraft sliding off the deck due to aq large wave causing a huge pitching moment? I know the S76 has a much lower clearance at the front and an articulated head, but it's been responsible for decapitating a few people over the years and a couple of S61s have removed their cockpit tops in similar circumstances.
