Kent, given insurance and fuel costs you got a bargain... He's doing instruction for the love of it and hoping to break even on his expenses...
Even with my gentle handling a 54 year old airplane takes a lot of love and $$ to get through the year, every year.. This years annual included new ECI Titan cylinders on the left engine, rebuild the fuel shut off valves, rebush the elevator rods in the tail cone, and a number of other small items... Last year included new gear hoses and seals in the hydraulic cylinders, and some gear bushings, and a replacement squat valve, and a new hinge for the rudder trim tab.... The year before was new cylinders on the left engine and the 1000 hour inspection on the props and a remanufactured power pack... Before that was making the flap AD go away, new fuel and oil lines with fire sleeves... Etc., etc. until you go blind.. Owning an old airplane is so much fun...
