    The time to swap the hub is at overhaul. At that point there's no additional installation costs. Your inspection cost is on the lower end and you haven't valued your time very high if you are only at $40 for the trip to the shop. Why are you using a 7 year payback? How long do you plan to own your aircraft?

    What is the concern about the autopilot? Is it because there are two parts listed? The STEC PSS-60 is a pitch control add-on for single axis autopilots like the KAP 100. It can hold altitude, hold a constant rate of climb or descent, and track a glideslope. I have one on my M20J that works together with my Century 21 AP.

    The price per inspection doesn't seem like much but over the life of the propeller I found it was cheaper to replace the hub. Using numbers posted above it is about $3,000 more to replace the hub at overhaul time. Where I'm located I had to fly to the prop shop once a year to get the ECI done at a cost of about $300. Even without factoring in my time (had to take a day off work each time) the break even point is only ten years.

    I didn't see any corrosion in Cody's pictures. What kind of poor maintenance would lead to a hub cracking?
  5. mooniac15u
    The service bulletin contains this language: "This inspection must be accomplished by qualified personnel at an appropriately licensed propeller repair facility or certificated aircraft mechanic with an eddy current qualification in accordance with Hartzell Standard Practices Manual 202A (61-01-02)." Just in general I think you need some kind of FAA certificate to sign off on any maintenance.

    Are you talking about using someone who doesn't normally work on planes? Who will sign off the AD compliance in your log book?

    He used their measurements and compared them to a more comprehensive data set. If you read the paper you will see that he discusses the various analyses done on the bones. I'm not sure I understand criticizing someone else's methods without reading the full extent of what they did.
  8. mooniac15u
    Did you read the whole paper? That's part of a larger discussion on the probability of the bones being those of Earhart. Authors are often prone to overstating claims in the discussion section but overall the data presented in the paper is interesting.

    This site has a pretty comprehensive list of serial numbers for each model year. http://www.mooneyevents.com/chrono.htm

    I think we should hold our insurance agents to a higher standard. They should guarantee that they have found the lowest rate. If we find out later that someone got a lower rate we should demand a refund. It should be no different than a PPI.
  11. mooniac15u
    It looks like @Jim Peace might have a gauge cluster.
  12. mooniac15u
    A PPI is for risk mitigation. When doing a risk assessment you do not normally attempt to mitigate all risk, only those risks that are both likely and severe. Otherwise the cost of mitigation will exceed the expected expense associated with the risk. Paying a mechanic to inspect every part and system on an aircraft to the level that they will guarantee it is like buying an extended warranty on a $20 toaster. If it helps you sleep at night, go for it but it is unlikely to net you a positive return on your investment.

    That's for the whole kit with mounting hardware. Since we were talking repair vs replace I just quoted the price for a replacement unit assuming you already had the hardware.
  14. mooniac15u
    The Plane Power AL12-P70 is currently listed for $453 at Aircraft Spruce. I believe that's the correct model for a 14V M20J.
  15. mooniac15u
    The part number depends on the aircraft.
  16. mooniac15u
    Exactly! They are repairable. PP (Hartzell) just doesn't want to. The repair department was probably too expensive to keep.
  17. mooniac15u
    That probably just means that it's not cost effective for them to offer a repair service. A new PP alternator is about $400 which seems to already be cheaper than other brands. What price differential would you want on a repair to make it worthwhile over buying a new one? Would you get it repaired for $300? I don't think I would.

    You don't know him or me and yet you just made a judgement...
  19. mooniac15u
    Maybe you could help @Hyett6420 figure out where to place his tiedown blocks so that the tiedown lines, the ground, and the imaginary vertical line to the tiedown ring makes a golden triangle.

    The density of 100LL will vary a little between batches. Typical densities can be found in manufacturers SDS's. For BP it is 710 kg/m^3 (~5.93 lb/gal) at 59 deg F. For Shell it is 744 kg/m^3 (~6.21 lb/gal) at 59 deg F. Shell even describes that density as "typical" in the SDS. The density will change with temperature but remember that it is the temperature of the fuel not the air temperature that matters. 5.82 would be at the low end of the range and would almost guarantee that your calculations are low in most cases.

    I wasn't actually trying to start a manual vs electric debate. I was just observing that the F vs J discussion usually includes claims that one should get an F because of the manual gear and at the same time that there are no age/airframe differences because the later F's are almost J's. If you want manual gear you are looking at 50-year-old airframes.
  22. mooniac15u
    I almost forgot... Later F's are almost J's and are practically the same age. But you don't want a later F because it doesn't have the manual gear.

    So, vintage cowls are great and may actually be better than M20J cowls. And in another thread vintage Mooney owners are trying to jump over each other in line for @Sabremech's cowl mod. Not too many J owners looking to mod their cowls. Many F's have been modded to be as fast as J's. But you don't want the windshield mod (which may have the biggest speed impact) because you can't reach your avionics. And in other threads vintage folks complain about having trouble sealing water out of the avionics hatches. Got it.
  24. mooniac15u
    Standby for the folks who will try to convince you to buy a C, E, or F instead...
  25. mooniac15u
    I'm not trying to suggest that the current rules make sense, just that it's not actually legal under the current rules for a pilot to replace these bulbs. Perhaps we could convince EAA/AOPA to put some pressure on the FAA to revise/expand the preventive maintenance list.
