The engine control switches on the S76 were not guarded or locked. On the L2 the levers are locked in a gate that requires sideways movement to unlock.
True, but the red fuel shut off levers aren't.
Still agree its very unlikely though. Plus, if it was a birdstrike, I'm sure the pilots might have mentioned it by now (!) and we'd have heard from EC declaring loudly that this was not a technical failure.
