I bought my plane in 2006, paid $21,000. Insured it for $25,000.
I Have renewed my insurance policy with the same($25K) hull insurance, every year since, no questions asked, besides hours flown PIC, type aircraft(always the same, Cessna 150H), and additional ratings acquired (none!),......... had to be answered by me.
Plus, and here's the big plus, My premimun has decreased.
