  1. A few points to ponder: 1. Prop efficiency: Bob Kromer (former Mooney test pilot) has stated that the M20J prop has maximum efficiency at 2500 rpm. However, with a constant speed prop, the efficiency curve is relatively flat, so it probably doesn't make a big difference over the range of normal cruise rpm. Lower rpm does reduce the horsepower lost to friction. On the other hand it reduces power once the throttle is wide open. 2. LOP: Leaning reduces both BSFC and power. One way of thinking about it is to run as lean as you can and still get the power you need for whatever speed you w

  2. This place was awesome! Needed an ignition harness called a more well known (better advertised) name company told it was a 12 day lead time after 13 days they hadn't even charged my card for a single harness. Read this post decided to give them a call last Thursday placed an order, told 3 business days then drop shipped. Called cancelled the original order. Got both harnesses shipped cheaper than the other place. Here it is Monday and sure enough as promised, harnesses delivered. Very pleased. Now I can get the plane put together and annual complete. Heres to Mooneyspace the network and knowl

  3. I was at the hangar today and pulled the Aux breaker with only the master on and the radios didn't come on. Weird, because I know that they did last time I tried it. But then I also noticed that I could turn the landing light on which is powered through the aux bus and should be disabled with the Aux breaker pulled. So I pressed the Aux breaker in and held it fully depressed and the radios came on and and the landing lights went out. When I released the breaker, it popped out a fraction and the radios went off and the landing light went on indicating power to the aux bus. Looks like the aux br

  5. You can visually inspect the stops yourself. Remove the inspection panel under the left horizontal stabilizer (see photo). Look inside, up, and forward. See photo- red circle is one of the stops (the other is forward of it), the green arrow points to the structure that it hits to stop its movement.

  6. I still think the speed mod that gives the most bang for the buck is extra gas. Fuel stops slow you down more than anything.

  7. The equation used to get BSFC is different depending on whether the engine is running LOP or ROP. On one side Fuel Flow matters and is part of the equation, on the other side it doesn't. Therefore it doesn't make sense to add either numbers to the chart. The chart can be read completely and appropriately using the numbers provided. But as @bluehighwayflyer said, I know how it works and how to use it. I cruise my turbo 252 in the flight levels somewhere between 20° and 30° LOP and enjoy a 35% fuel savings for only a 10% speed penalty. It also keeps my cylinders cool and my turbo happy.

  10. I thought possibly a data base exists which gives validity to the continuance of the Eddy current test for the hubs. Maybe it does, I just need to search (as you suggest). Hmmm! My propeller shop ( for 33), to the best of my knowledge, has never discovered a descrepant hub via the AD. You are correct, it is a pain!! I am, and have been since the AD inception, wondered is it, or was it a knee jerk reaction to limited situations, or as others ( love that term ), a political move to sell new propellers? Have I mentioned the AD is a HUGE pain?

  11. Don is local to me at Cannon Creek and rebuilt my Bendix's in an afternoon. EXTREMELY competitive pricing. IIRC I paid $450 for him to IRAN both with new points, contacts, wipers, etc, etc, etc. Of course he was a mile away so no shipping.... I highly suggest him. He also builds and overhauls engines and has been a staple in North/Central Florida for quite a while.

  12. Yeah, that's a later model year fix. I have had the difficulties with my trim moving on my '62 as well. We even paid a mooney service center to "tighten up" the trim, which did nothing...not even certain what they did. One thing we looked at was retrofitting the later friction device. We decided that a newer trim wheel would be required (as the original was not designed for the added wear). A hangar elf put some friction material between the trim wheel and the riser and I haven't had nearly as much of a problem since.

  13. One thing to keep in mind about instruments with backup batteries is that batteries degrade over time. The ICA for each instrument usually has a requirement for periodic test and also replacement intervals. Also the main battery should be capacity tested annually. As lead-acid batteries degrade, they lose capacity. Just because it starts the airplane fine doesn't mean it will run your panel for any length of time. Skip

  19. Lot's of flying recently. IFR training flights on the 20th, 24th, and 27th. You can read about those flights over in my training thread or on my blog. In between I squeezed a short 15 minute flight on the 26th over to KRAL after work for some less expensive fuel and to see what it looks like outside the plane when you are flying. Yesterday afternoon after my morning IFR training flight my wife and I took her sister-in-law for her first small plane flight along the coast down to KSEE for a late lunch. The smallest plane she had previously been in was a 12 passenger puddle

  20. Thanks @carusoamfor leading them to the growing list. @KLudwickowns an E and is willing to travel if @mike_elliottcant make it up. I’m close but have very limited E time, let us know @Hakarhow the search goes. Maybe reach out to the guys in Dalton Georgia or Daytona MSC to see if they know of someone who could help.

  23. There are numbers. I added the notes in red by looking at the scales on the chart and drawing lines. You are welcome. On this chart, Lycoming provides values for delta-T for EGT and CHT and then values for %-power. BSFC is the only thing without units. As noted this is for relative performance, but you can still begin drawing conclusions on where the highest thermal efficiency is, and what your power compromise would be. You do not need fuel flow, delta-T is just as useful to find your place on this chart. You can estimate FF from the 15xGPH estimate if you like. Regardless, this

  24. RPM would probably concern me more. But it never gets into a range that would be concerning. I'm also flying a TSIO360MB or SB when I get it back. I have my EDM900 on the left side of the panel and watch it religiously. Red numbers are never a cause for alarm because I was already watching them when they got there. It's just the way I fly my airplane. I'm more like the Flight Engineer. The autopilot is usually doing the flying and I'm working the radios and managing the engine.

  27. Mooneys are already pretty slippery as-is, so aerodynamic mods will only net you a couple knots here and there. An often overlooked way to increase speed is to reduce weight either from the plane or the meat bags inside. This is doubly beneficial because it also improves useful load for when you need to load to max gross.

But I’m a bit il-prepared... can’t go to the prop guy without knowing the AD... Past midnight in the east coast... still going through the rest of the reading... -a-

  33. Does anyone else find it confusing that "engine reference manuals" contains airframe maintenance manuals and "Pilot operating handbooks" contains parts manuals? Would it not help to add a few more categories and reorganizing the documents that are all ready there. Some examples of new categories would be like: Parts manuals Mooney Service Manuals STCs and 337s ADs and SBs Checklists I would be more then happy to help catalog if able.

  34. Ok, that jarred it loose! Thanks. I even replaced my master switch last year and already forgot it’s a “Single Throw, Dual Pole” switch. So not only does it cut power at the battery relay, it also cuts the field wire which shuts off the alternator. Newer folks may have the battery/alternator split switches. My brain was somewhere else.

  35. The same inspector said anybody that does 100 hour inspections is a fool. He said in most cases there is little or no difference in the effort between an annual and a 100 hour inspection. You might as well reset the annual clock. The only advantage to doing a 100 hour is it doesn’t require an IA. He said he supervises plenty of IAs who do 100 hour inspections.

  39. I’d have to have an empty copilot seat, a full size adult in rear seat and 100 lbs in the baggage area to exceed rear balance and don’t think I can exceed the forward balance. Under normal circumstances, I won’t have to worry about it.

  40. That doesn't appear to be true for any Single Engine piston under 6000 lbs, only for all others - from the AFMS below. However, IMO as a CFI-II I wouldn't ever be caught out doing training in actual IMC with only GPS on-board - that's nuts given how easily they're jammed and with almost daily GPS interefence testing NOTAMs putting it at risk of losing coverage. That said, all I ever use to navigate is GPS. But I have lost GPS from jamming 3 times now, including being IMC, (although not yet in US airspace) and each time I was abe to fall back on VOR navigation. So for me, not even two TS

  42. I did not have the original weight & balance and equipment list for my airplane. It was exported to Canada in 1977 and when imported 25 years later, the original logs for N6835V weren't with the plane (1975-1977 missing), nor the original weight & balance. Friday afternoon I emailed Mooney asking if they still had the records. Within 2 hours, Kevin Kammer, Director of Customer Service answered back that he would try to find what I needed. Monday, 11 AM, Kevin emailed copies of the original weight & balance and equipment list dated 6/19/1975. I am impressed with that kind of ser

  44. To answer Corusoam's question, there are no marks on the elevator. But since it has a sharp edge, I wouldn't expected that the light contact that occurred would produce any marks on the elevator. I do recall that either on the pre-buy (1994) inspection or during an annual shortly thereafter, some corrosion was found on a rod. It was cleaned and repainted. I'll check the logs. I will also perform the check Skip suggests. Clarence, can I visually inspect that the travel stops? Nick

  49. I don't mind getting the vaccine, but I don't want to sign away my HIPPA rights and get in their damn database. It's none of the governments business what medicines I've taken (I know, I just did MedXpress) or what businesses I've visited. They are trying to get us to a point where you won't be able to do anything unless you identify yourself to prove you have been vaccinated. This will allow them to track your every move. None of their damn business!
