I've been asked to convoy a light twin from UK to Africa. The buyer is arranging the insurance. He rang me and asked how many hours I had on the particular light twin. I replied truthfuly that I had never flown that particular model (but have several thousand hours on other light twins
As you have several thousand hours on many light twins as long as this one is not very different the insurance company should accept those hours without much loading on the aircraft.
In that case a thorough checkout on the aircraft should suffice.
What twin is it and what have you flown?
