I previously posted the incident, but thought I'd update the list. Prop has been rebuilt - hub checked ok, but installed new blades, bearings, and seals. I basically got a new prop for $3000. Engine is torn down and all components NDT'd and found no damage. Corrosion found in hollow crank. Being fixed now. (AD) About $6500. I removed all hydraulic components and had my hydraulic shop at work check out the switches and actuators. All good except hi pressure switch was switching high off-scale. Nose gear actuator was allowing fluid past the piston. I suspect that actuator was responsible for the incident and that the switch was the root cause of the nose actuator failure. I decided I'd also check out the pump. I called Lancair about a new pump and got a quote for $985. I called Oildyne for an inspect and repair as necessary. The salesman asked if it was used on an airplane. When I replied that it was, he said the teardown and inspection would be a minimum of $300. He explained it was because of the FAA. I replied, "Great! I didn't think I'd get a certification with the pump, but obviously you guys are now PMA certified." That caused much hemming and hawing. I then told him that I didn't mind exorbitant prices if the justification was that they could get them from rich pilots, but that I didn't appreciate BS. He then suggested I contact one of their distributors and located one nearby for me. The gentleman there, nicknamed "Roach", was extremely helpful. Said I could get a new one for about $300 and that the shop rate was $70/hr, which would add up pretty fast. Then he said, "Why don't I sell you a pressure gauge and attachment fittings and tell you how to test it. It's pretty easy." He went in the back and brought out a similar pump and proceeded to teach me the ins and outs for about 15 minutes, including what to expect and what various failures could be indicated. He then volunteered to determine and supply the correct parts if I found problems. So for $31, I was on my way, much smarter and very pleased with the treatment. The cost of finding the corrosion is gonna be about $12,000. Would have been cheaper to just tear down the engine!
