First thing to look at is the JAR-FCL definition of a multi-pilot helicopter :
Multi-pilot helicopters:
A type of helicopter that is required to be
operated with a co-pilot as specified in the flight
manual or by the air operator certificate or
equivalent document.
It depends on what type of operations the Authority (general term for CAA, depending on wich country you're in) considers must be performed by a crew of two.
For instance in France, the following types are considered multi-pilot helicopters anytime :
S61 - S92 - EH101 - BV234 - SA321
For the others, it depends :
- a SA330 performing public transportation is considered multi-pilot.
- the same SA330 employed in firefighting is a single-pilot helo.
