Most CS props in the US print suggested inspection and maintenance at

I'd be a little concerned about some kind of sludge in the CS
mechanism. However cycling the prop a few times before takeoff would
"hopefully" resolve this question.
I'd guess $1000 to have it done. What's your peace of mind worth?


Here in Anchorage a 2-blade CS prop O/H is usually about $1500 assuming
all the parts are servicable.

I'd be a concerned about an airplane that has only flown 6 hours in the
last 15 years.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.
