Just got finished on this year's annual.
All cylinders were in the 70's plus. Oil burn has been averaging one quart every 10 hours. Parts needed were purchased at
www. iwantcessnaparts.com where they say you get 40% discount.
The IA used has done many skymasters and knows this one very well.
He charges 2,500 and that includes all labor outside of parts, approximately 600 this year.
I did change a few things as to how I flew the airplane from last year.
The first is that I fly as high a power setting as possible all of the time. Second is that I quit using Avblend with the oil changes.
My mechanic actually said that the compressions were better this year than the last two years.
