So my mechanic guy called me back after inspecting the plane, and he wasn't sure the asking price reflected the condition of the aircraft.
His squawk list started with some small and or easy to repair stuff:
1. Empty whiskey compass.
2. Throttle/Mixture controls are stiff, the lines need lubrication or replacement.
3. The latch that keeps the door from hitting the cowling is disconnected because of a missing screw.
Starts to move to the more expensive:
4. #2 com is weak and has a lot of static, #1 is ok. The NAVs were ok, but he couldn't get the DME to indicate.
5. Window seals leak. It just rained a lot down there, and there was some water on the edges of the carpet on both sides. He suspects the seal around the door too.
6. The switch for the nightlight is real loose, and the domelight is inop. Could be a lightbulb, could be something more complicated.
7. The propeller is the original. As the plane has been on a 100 cycle for all of it's 8500+ hours, the "let's file off the leading edges to take care of knicks" strategy has brought it to a point where he's not certain it would pass a legit annual inspection or prop overhaul, so budgeting a new $2800 or so prop would be wise.
8. Left main tire worn, needs replacement.
9. The gas gauges read high. The tank was 1/3 or so, but the gauges read full. The FARs only require them to be accurate when indicating empty, but I've got suspicions that they may not, in fact, do so. I fly off a clock, not the gauges, but they're useful for noticing leaks and are a definite airworthiness item.
He said one of the cylinders had great compression, one was ok, and two felt a little weak.
He wasn't confident in the last annual it got, and advised me to have a full bore annual done as a condition of purchase, including borescope inspection of the engine, checking for metal in the oil filter, etc. While he was saying this, I was getting a definite vibe that he wasn't terribly confident in this plane, and that it had been "ridden pretty hard and put away wet", to interject a colloquialism.
After this, I don't think I'll buy the plane, unless the guy takes a much lower offer that accounts for the amount of work needed to bring it up to standards.
It has a nice "classic" IFR avionics stack, but that's not worth anything if the avionics transportation device (ie, the plane) can't fly.
