I may have got a little mixed up here with LPC/OPC but let's see.
Without looking it up section 6 would be asymmetric stuff? My MPA IR is currently on a single pilot aircraft operated as multi crew.
Now, I am relatively new in my company (approx 4 months) and as far as I am seeing it we get our MPA-IR type revalidated on every other OPC. We have an annual LPC which is done on a line flight with one of about 6 line training captains, some of whom are not CRI/TRI or CRE/TREs.
Now getting back to section 6 and the SPA IR. If I do my normal OPC (assuming I haven't had some strange vision above and I am describing it correctly), I will have my MPA-IR revalidated on every other OPC (2/yr). Seeing as these are single pilot aircraft, I assume I could then complete section 6 with the examiner removed from his previous multi crew duties and this would satisfy everything?
Cross crediting on a MP type (let's say a 738) then I assume you can only get away with revalidating a SPA-IR-SE because while 3b still credits, there would be no need for section 6?
The joys of legislation and trying to wade through it when you are unfamiliar.
Please let me know how wrong I have it so I can learn!
