My insurance company required a checkout by a "qualified" instructor, not time in type. When I needed my checkout, I requested approval of a pilot who was not an instructor, but had extensive experience in RV's and was a current military pilot, and was granted that approval. When my son required a checkout, I requested approval of another pilot friend who had experience as a military instructor, was a current airline pilot, and had 100 hrs RV time. Again, this was approved. The lesson is that if you have someone in mind that logically should be able to provide a knowledgeable and constructive checkout, but who doesn't meet the letter of the insurance company's requirements as a check pilot, ASK! They are smart enough to understand that a pilot with the right experience but not the official qualifications will provide a better check ride than a CFI who lacks specific knowledge and experience in our unique aircraft. They are more flexible than you might guess!
