Your point on the S-92 AD is well taken, but our offshore workforce in the majority don't see the ADs and inner workings of the airworthiness systems.
The Union guys who do take an interest say that while the S-92 has and may still have a few issues, Sikorsky generally understands the problems and works on a fix while EC doesn't seem to fully understand the 225 (or L2) MGB problems.
The passenger perspective is that the expensive ($) new technology helicopters from an airworthiness point of view are less safe than some of the older generation aircraft and I find this a difficult argument to counter. Notwithstanding the "working but not indicating" EMLub, the concept of a safer gearbox to the workforce does not exist.
