According to the JAA definitions, if you are operating an aircraft (even one certified for single-crew operation) in a multi-crew operation, as defined by the ops manual or by national regulations, then it is de facto a multi-pilot helicopter, and you need a multi-pilot type rating.
Surely the operators knew this... why did the national authority inspectors not pick it up?
