    Prop strike on Continental

    Continental crankshafts have a surface hardened propeller flange. They easily crack without bending so the dial indicator does not tell all. We did a prop strike teardown on an IO-520 that whacked the towbar and necessitated replacement of the prop. The crankshaft was cracked in the aft flange...

    Corrosion Pitting on Cam (or Crank?) on o-470R What to do??

    The engine must be disassembled to change the cam. The best way to proceed is to have it disassembled and inspected and get a price to do an IRAN (just fix it) or a major overhaul and make the final decision based on the Cost. Right now you are on the hook for the labor plus a lot of parts...

    What's wrong

    I'm not an IA but IIRC the proper signoff would be as stated but finish statinhg the aircraft is unairworthy and the owner has been provided with a written list of discrepancies. Once the discrepancies have been cleared and repairs logged the aircraft is then airworthy?

    Cherokee 140/160 prop pitch

    It's 60 INCHES not degrees. With the 58" pitch prop the engine will turn pretty close to red line in climb and red line or above in level flight wide open. If you are operating out of a very short field or at high elevation the 60 is a better match. I actually pitched one of mine to 62" and it...

    Fixed-pitch vs. Constant-speed

    Most of the factory airplanes that were certified with both CS and FP props have a slight speed advantage with the FP prop. ie the Cherokee 235, Cherokee 6-260 and the BE-24 fixed gear model. Takeoff and climb performance is a bit better with the CS prop. While the CS prop will usually turn...

    Ask the company supplying the STC what shops if any in your area have done the conversion. You don't want to pay the extra cost of someone learning how to do the conversion. Charlie Melot X partner in Penn Yan!

    What's the going rate for a O-540 overhaul?

    Do cylinders have to be inspected and/or forcibly reconditioned as part of a bottom overhaul? I know it's sensible and customary because of the practicality involved in having the engine cracked open , but is it required by the reg? And yes, I'm aware bottom OH is the only legal kind of...

    Looking for the elusive Continental IO-360-B

    43 years in the engine business and I have never seen or heard of an IO-360-B. Probably easy to convert an A, C, D or K. WS price is about right for an outright purchase. Charlie Melot Zephyr Engines

    Penn Yan Aero Conversion Kit

    It is a great conversion. Do it if you can! Having been a partner and test pilot at Penn Yan years ago I had the privelage of flying a bunch of them. A clean one will true 130 Kts wide open at 7-8,000'. Saw some light ones out the door with a useful load over 1040#.

    Penn Yan Aero Conversion Kit

    It would seem unlikely that the kit includes the parts to convert an O-320 into an O-360. The conversion requires a crankshaft, connecting rods, pushrods, cylinders and a carburetor.
