I fly a 1992 build two seat RANS S6 that I have owned for the last 10 years. It is operated on a LAA Permit. During that time it has had the usual routine maintenance, been recovered once and had one new engine. It us used for about 50 hours per year. The total cost during that time has been £42k.
This includes hangarage at £125pcm and insurance that this year was excessive at £680 (but then I had a claim as I did bust a prop whilst taxiing and had to pay for a new one plus an expensive engineer to shock test the engine! )
