Or is the OP maybe a "concerned observer" who needed some advice before calling the CAA, but removed some detail to protect the presumed innocent?
Looking at the amount of threads about logging P1/P2 in a single pilot aircraft, and from actual experience, I know there's a lot of confusion and a lot of pilots logging hours they're not entitled to. And some of these improperly logged hours are used to claim experience for the issue or revalidation of a rating. That's where things may get tricky.
Not to mention a concern a group member may have about the consequences if somebody wrecks the aircraft, and the insurance finds out that the person who was handling the plane had a history of claiming P1 time on that aircraft, but was not insured to do so.
