Are you asking about a "Multi-engine Land" rating? Or a "Minimum Equipment List"?

No multi-engine rating needed. It's a single engine airplane. The company may want you to have one though.

If you are asking about a Minimum Equipment List. No aircraft is required to have an MEL. However, if something breaks, and you don't have an MEL, the plane is grounded. The MEL allows us to continue with a flight, even with equipment inop, in specific circumstances.

Planesense aircraft do have minimum equipment lists (MEL)
