Looking to possibly upgrade to a turbine. Just wondering what the consensus was concerning a/c of this type that have not flown for a few months maybe longer. Are there hidden possibly significant costs mainly concerning the engines in getting them running again?
Having been there and done it for a single engine piston, underused plane is not good. Don't know anything about turbines.
2 months doesn't to me seem like a long time, but the "maybe longer" would concern me.
It took me two years to get everything that turned, pulled pushed and toggled working in my Sundowner. My plane was only flown 10 to 15 hours in the prior two years of me purchasing the plane
Engine for me, was high time (1960 hours), and I had it overhauled when I had an exhaust valve bite the dust in flight and a second cylinder started acting up while on the ground after cylindar was replaced..
Informal probable cause was from the lack of useage doing all sorts of nasties internally in the bottom half of the engine engine as compressions were 75 and higher for all cylinders.
Equally and probably more expensive part to getting fixed will be the avionics and flight instruments. Lack of movement doesn't bode well for parts that require lubrication for shelf life.
Can't stress the importance of a good prebuy.
Hope this helps a little bit.
