Sounds like the same scenario but there comes a time when systems enhancements (VEMD, IIDS, etc) differ too much from the "original" product.
Remeber when the B407 was classed under the B206 endorsement? CASA then saw fit to make the 407 a different endorsement altogether. Not a bad idea if you ask me.
I suppose they will look at the new AS355 and decide in good time.
Does anyone know if the physical dimensions of the aircraft differs from the AS355N?
