From a maintenance point of view the Puma family falls into four separate groups.
330, 332L/L1, 332L2 and EC225.
These are the division lines where it is considered that a sufficient difference exists as to require a separate type rating for maintenance purposes.
This is defined by EASA regulations specifically Part 66..
So from a maintenance perspective North Sea Tiger is correct.
