Bobcat-
Just make sure you are careful about how you present your 350 time. Last I checked, it is a single-pilot airplane that requires a type rating (although I am certain that it becomes two-pilot automatically once a certain amount of pax are carried). So, you can't log it as PIC (unless of course you have the type), and you technically can't log it as SIC (Can't be second-in-command if only one is required for command)...but you can log it as total, multi, and dual received, assuming the PIC signs your logbook as a qualified MEI or ATP (due to ATP privileges in 61.167). In this position, if I didn't have the appropriate signatures there, I'd make it completely clear exactly what that time was, so that they didn't think I was trying to pad multi/turbine experience.
This issue is interpreted differently by just about everyone, though...just make sure you can back up whatever you have logged with the FAR's, so if they ask, you'll be able to provide a defense. Good luck.
