Multi Pilot / Single Pilot Training

[Terry_flyer]

Hi all,

I need your help.....

I am currently rated on a SPA and have recently done my LPC/OPC/IR. If I wanted to get the aircraft approved by the CAA for Multi Pilot ops what training would be required....would I need to re-do a MP LPC/OPC/IR or would my current LPC/IR stand and I would only need a MP OPC?

Any help appreciated
