The difference is very clear, exactly as @johncuyle says above. The mechanics that don't know any better, adjust your max FF for 40" redline (really overboosting it by 3" with the intercooler) and then when you take off at real intercooler redline of ~37" your FF is a few GPH's too low. Good chance TIT is climbing above 1450F with everything forward - which should have your attention before liftoff - and CHT's will escalate.

Starter adapters wear out and slip regardless of what kind of starter you use. Its a fact of life. Yet their have been some unfriendly starters that have caused starter adapter damage or premature wear by not releasing. That said, always try to to get yours repaired rather than overhauled exchang if you want to save money. Repairs can be very affordable compared to overhaul since until the shaft gear is worn beyond limits it can be turned down in size a couple of times and oversize springs can be installed. Eventually you'll need to replace the shaft gear with new and the cost of repair will more than double. But if you go the exchange route, you could be sending in your adapter, which may never had its shaft gear turned down yet, and get back one on exchange that was at minimum diameter which will need the costly replacement next time. Its pretty well accepted that starter adapter longevity is increased with single weight oils and switching to slippery/thinner multi-grade oils and adding camguard is going to enable almost slipping adapter to slip more easily and thus sooner. But most consider the benefits of camguard and perhaps the real need for multi-weight oil benefits for the rest of the engine outweigh the negative aspects they have on the starter adapter that works by friction.

The strap is an interesting idea for the nose wheel. I've done mine multiple times, no special tools or strap are needed on the mains. Don't even need to remove tires/wheels. Just put the aircraft on jacks and use the jacks to lower just enough weight on the mains till you can access the bolt and nut that goes through the collar. Then remove the nut and washer on collar bolt, push the collar bolt through the access hole you'll find and grab its washer. With the bolt and its hardware off, just jack the aircraft up till the top of the shock link tower falls out of the bottom of the gear exposing the disk. The nose though does require compressing beyond the weight of the aircraft on it; so the strap sounds interesting. If you just replace the disks its very quick and easy. But there is really more to it than that. You really need to inspect the interior base of the shock link tower/tube. It typically collects moisture and with no where to drain, it rusts at the bottom. It it's been many years with significant corrosion there is a very good chance they really needs to be changed out (10% of wall thickness). LASAR sells their PMA'd version for $500 (significantly cheaper than from Mooney) and you may also need their PMA'd bearing they attach with for another ~$70. But at the least, the shock link tube should be cleaned up to verify corrosion hasn't exceeded 10% of tube thickness, repainted and treated with something like ACF-50 to help protect them. I spray some in the top at every annual since the links aren't cheap. Anyway, that's just how I do it.

So how does N2 violate the basic laws of physics i.e. Boyles Gas Laws where PV=nRT ?? Sent from my iPhone using Tapatalk

The forms are nice, but the real value is in keeping up with new AD's that may affect not just airframe or engine but any appliance as well. That's a lot to keep up with or search for. Well worth the $40 a year renewal IMO. Sent from my iPhone using Tapatalk

Check the electrical connection and voltage at the Sonalert and make sure it's wired properly with respect to polarity. Hopefully it's not the voltage that is dropping off. Sent from my iPhone using Tapatalk

Your in my home turf. It is really hard to see the airport on final, especially if you don't see it before you get real low since that make it harder to see. More than likely he was referring to the FAF waypoint QEWTI. Most likely he was vectoring you to final and put you on a 30-45 degree intercept heading with final and gave you the distance from QEWTI when he said cleared for the approach. And if VMC conditions, the final vector to intercept final could have been only a mile away from QEWTI. Sometimes/often they're real busy making it difficult to ask them to spell the fix. But if you went through final, there is no shame in asking for vectors back to final to allow you to get set up. Be careful, because its not unusual for there to be a miss-communication on which approach you are being vectored too or cleared for (such as RNAV) and if not being vectored on to final it could result in you navigating off his intended course (your clearance) and it's usually the pilot that gets the violation if there is a loss of separation. In this case the RNAV and LOC are almost identical so I doubt that would be an issue here.

With regards to sealant longevity, my '86 has never been resealed - at least no logged and that's over 30 years now. I think we see a very broad range of years of how long tank sealant last. A very interesting comparison is to the Cessna Cardinals which have similar sealed tanks, but those birds don't get their tanks resealed - at least not yet and they were built between '68 to '78. So what's the big difference - you guessed it, the landing gear is attached to the fuselage rather than the wings so my guess is their is some truth to the notion of the need to change out of the landing disks and avoid hard landings to minimize the shock transfer to the wet wings.

Yes, that is exactly what the STC instructions say to do, set max fuel flow for 100% power per the intercooler temperature table they gave you which should be about ~37.5" MAP. At Savvy, we like to see Continentals high FF number from their specified range of 23.0-24.7, plus 0.5 to 1.0 GPH above that so would prefer to see in the range of 25.2-25.7 GPH at ~ 37.5"

I haven't yet used their app, so their website may have different functionality than their app. Their website allows you to look at total clouds, low clouds only, middle clouds only, high clouds only (all by coverage from Scattered, Few etc.), cloud tops and cloud bases. The cloud tops function itself, which does 0, 15K, 30K etc doesn't give as much resolution as just toggling between Low, Middle and High. Its based on the same data as the GFA forecast tool on aviationweather.gov replacing our textual forecast area, but I find Windytv.com provides much better graphics, better resolution and also lets you choose between different resolution models (NAM, ECMWF and more).

The easiest to use web site for clouds and could tops is windytv.com - way above the rest. SkewTLogPro is great for a point in space, like your departure and destination, but not that helpful is x-ctry planning IMO. Sent from my iPhone using Tapatalk

Yes, the 900 series monitors automatically go into 1 sec sampling rate while in LeanFind mode so that you'll get better resolution using LeanFind. We prefer to always be looking at the better resolution data and suggest setting it for its fastest rate - which 1 sec for these. But 2 sec (such as the EDM 830) work okay too.

Hi Paul @gsxrpilot that's the profile under Help or http://content.savvyanalysis.com/static/pdf/SavvyAnalysisFlightTestProfiles.pdf We suggest no more than 65% power, I suggest 24"/2500 and 6K'. That equates to near 60% power in ours and 24" at 6K puts ambient atmospheric pressure near the same as MAP which is advantageous because it prevents an induction leak for significantly affecting the results. (But if we see evidence of an induction leak we'll recommend a follow up test - we just want to ensure we can get good gami results). Be sure to go slowly as each cylinder peaks and well into the LOP side (about 50 LOP if able). With the JPI 900, I suggest putting it on 1 second sampling rate for the highest resolution - then re-boot the monitor before collecting the data. Then you need only do 30 sec per mag doing the LOP Mag test including Both in the middle to give time for EGTs to re-stabilize. But shoot for around 50 LOP when you do the mag test and I suggest doing it right after your last gami sweep from ROP to LOP so I can see exactly how LOP the test was done. That way if we do see missing we can tell if it was premature or acceptable. I don't mean to overly complicate the procedure, its just that the above helps to give the best recommendations for maintenance if we do see any anomaly's.

Bob, No problem. Bob & Paul - yes, you have access to all the tools I use. To measure the Gami spread first zoom in on series of gami spreads that you want to measure. I prefer to add FF to the graph as I pre-examine the data for quality. You don't have to incorporate the following check I do first, but its especially good for turbo's and any NA engines not running at WOT. So I first have a graph of MAP and RPM and check to verify MAP and RPM were reasonably constant the entire time. 0.5" MAP variation is acceptable multiple inches of MAP variations is not and very common on turbo with either fixed or pneumatic waste gates. But that's another tangent. Once satisfied only FF is changing, then click on the G for Gami icon which is highlighted in my screen shot above. That will eliminate all but the one Gami mode chart and why I pre-screen with MAP and RPM before entering Gami mode. Then in Gami mode click at the start of the time line - and see a cursor line labeled "Start" and then click again when FF is at the opposite range (high vs Low or Low vs High). Just be sure unlike the screen shot above to only bracket one peak with FF either going up from LOP to ROP or down from ROP to LOP. After both start and end cursors have been clicked you'll be able to see your Gami spread data in the data box - upper right corner. To get out of Gami mode and back to multiple charts just click on the X at the upper corner of the data box. There is also help published on all the tools available by clicking Help in the upper right corner. Paul - feel free to request analysis at any time. But we ask you to fly the Savvy Test profile along with a full power takeoff and climb for analysis request so that we have multiple gami sweeps and LOP Mag test data to report on. With full Savvy test profile data you'll get a full report back. Cruise data alone doesn't give us much to discuss unless were looking at an anomaly. We especially recommend requesting analysis of your Savvy test profile data before and again right after annual to ensure all is good.

I had to download your CSV data file, add an elapsed time column as =B15-TIMEVALUE("14:51:30") in order to get us on the same time line and then I could see what I believe you are referring too. Notice that on Savvy's elapsed time line, my Gami spread data was between 1:01:24 to 1:01:53. The 1:01:53 elapsed time corresponds to to 15:53:23. After 1:01:53 window of the gami spread, indeed the FF does go back up to 9.4 for a few seconds, the last data point its at 9.4 is 1:02:14 elapsed or 1:53:44 actual time, the next 2 following seconds and data point is where Eztrends reported 3 & 4 peaking (again). But this is really invalid to go by that because. As you said, the leaning past peak the first time was done earlier as reflected by the gami spread reported above ending at 1:01:53 elapsed (or 15:53:23 actual). But only since the monitor is in Lean Find mode it continues to see it come back to peak in reverse with FF being enriched for a second peak. But if I simply expand the gami spread measuring window to include both peaks it will report the same way EZTrends did (incorrectly). Probably not saying anything differently than your last post but I was pretty confused till I dug into the details to resolve the time line differences and take a closer look. I think a graphic does a much better job of illustrating it.

Yes it is. LASAR used to make one too that was smaller and simpler to install on the recognition light switch, but they dropped it after Precise came out with this one.

The simple solution to the "hot" recognition lights is to install a Precise Flight flasher for them. Then they pulse like strobes which improves recognition and keeps them cooler so they'll never melt the lenses if you forget to turn them off after landing. Plus the bulbs are cheap if you are willing to grind down the edges and solder on wires onto the original projector bulb. Sent from my iPhone using Tapatalk

Inexpensive paper POH's are available from https://www.esscoaircraft.com/ Or official POH's and digital copies are of course available through Mooney which can be ordered through any MSC or LASAR.

This is what I measured Time: 01:01:18-01:01:53 EGT2 peaked at 9.2 EGT1 peaked at 9.1 EGT3 peaked at 9.1 EGT4 peaked at 9.1 GAMI spread is 0.1 Although fairly quickly done, FF was monotonically decreasing as they were peaking and MAP and RPM were constant. So nicely done. But would really want to see an average of a few sweeps to ensure consistency. But it looks like good data too me!

@Jim F nailed it. The state property tax is 1% ever since Proposition 13, but every county has add-on's from various bonds voted in bringing it up to maybe 1.1% or more, so just google the property tax for your county/city. Then each county has their own method of assessing value which they will do on their own. The only thing the purchase prices seems to really count for is the sales or use tax you will owe the Ca Board of Equalization (BOE) - which is based on your city/county sales tax rate for the purchase tax from the bill of sale. There was a program that allowed private owners to avoid CA sales tax when I bought mine (which I took full advantage of) but that program was ended years ago. From what you read on the internet, it appears a fair number of owners try to escape the sales tax by not reporting it but that's silly as there is no way to hide it unless you are parking your aircraft in your garage or something like that. Every airport FBO, hangar lessor etc is required to know before renting and report to the county the N number for any space or hangar they rent/lease. When they figure out the sales tax wasn't paid for whatever reason, I hear they stick them with penalty's and interest just like any past due tax. It doesn't matter if you bought it out of state, acquired it under a LLC, or even registered it in another state. You rent a hangar or ramp space to park it her in CA you'll owe the sales/use tax unless you brought it under the remaining tax free program with letter of exemption from the BOE which these days is limited solely to business use. But another crazy thing discussed here regarding CA is that some airports are known for passing on the hangars annual property tax bill to the renter. Seems crazy, although we know we're paying it as well as the utilities regardless of how its billed. if anyone is spending multiple hundred thousands I'd recommend contacting a professional in this area; especially if you can claim business use. Some other states are even worse, we've read here on MS owners parking their Mooney's in FL for a few months for maybe maintenance and then getting a property tax bill from FL.

LOL's, Thanks Jim, I corrected the typo. Sent from my iPhone using Tapatalk

TCM's spec for metered max fuel flow for the 310 HP IO-550 in the -N configuration is 25.6 - 27.3 GPH (just as @M20S Driver and @StevenL757 pointed out above) and we at Savvy like to 0.5 to 1.0 GPH above the high number yielding a target max FF of 27.8 to 28.3 GPH for exactly the reasons @kmyfm20s cited above, and essentially exactly where @Jeff_S is at. (knowing the kind of summertime flying @kmyfm20s does out of the desert, I can understand exactly why he's pushing his to 2 GPH above). But one gallon above isn't going to rob an appreciable amount of power but it will sure help keep the engine running cooler till you are ready to lean further. We'd really like to see the 310 Ovations in the low 28's GPH. Apparently JPI is trying to stick to the middle of the range which makes no sense.

Its in the back, very close to above the sump, and where the remaining fuel is in level flight. But also where you need it in climb and climb gets my vote over descending.

Hi Jim, Not really a leaky exhaust valve per se but a burnt valve. Although once a valve is burnt, if its not leaking yet it will be very soon. Our FEVA software detects many burnt exhaust valve as it sticks while rotating, momentarily heating up, then cooling back down as rotation resumes. It creates a symmetrical signature that our software detects and alerts us. Unfortunately its not perfect, not all burnt exhaust valves exhibit the pattern. But we've also been able to save a number of exhaust valves with our maintenance clients that lap the valve in place when caught early enough to clean it up and stop the sticking. But even if we don't detect it early enough to save, its still much better detecting it before the cylinder swallows part of an exhaust valve! Incidentally, I am not referring to "sticking" as in sticking in the closed position as seen in a cold engine at startup (e.g., morning sickness) but sticking as the valve rotates as it open and closes as it is designed to do. Hope that answers your question. Paul
