M20M TLS… most have been updated to Bravo. Oil cooled heads are good for improved TBO…. Make sure to ask. M20R… Many have been updated to 310hp from the original 280… If climbing into the teens often Go 310 HP. There have NOT been any after market STCs to add a pair of TNs to the M20R yet…. For best performance… M20TN… AKA Acclaim… If you find M20U and M20V… they are the latest versions of the Ovation and Acclaim Ultras…. Complete with the latest avionics, some composite skins, and a spare door… Best regards, -a-

Got to love this ancient standard… too hard to remember, to complex to get right… How hard would it be to use their actual dimensions in conversation? 4.5” and 5.75” -a-

That would require somebody that knows math and aviation at the college level… Let’s see if @aviatoreb would know anyone with insight on that subject…. (Mathematics of stall speeds during a slip…?) Best regards, -a-

I know I owe at least two apologies for yesterdays posts… @jrod_stat and @Someguy Two new guys came aboard and I lost the balance of sharing knowledge and maintaining control at the same time… I’m still learning this skill called writing… And getting better at it every day. I still have a ways to go… Thanks for pointing out this error… It helps me with getting it more right the next time… Best regards, -a-

Oddities related to bladders… They have detailed instructions about putting foam blocks under the fuel cells… for draining purposes… Ensuring the install occurs properly, and gets maintained properly… down the line is a good idea…. Less data, and fewer people have the fuel cells… Fortunately, the fuel cell people were real, and not non-aviation people converting a good idea from some other form of business… Use caution if you seen any unusual folds develop in the floor of the bladders… Best regards, -a-

@ sign is key… @jetdriven memory of everyone’s screen name also helps… Best regards, -a-

Some People I would invite for that discussion…. @donkaye @midlifeflyer @KSMooniac a collection of great CFIIs and an engineer… Best regards, -a-

That STC was successfully transferred recently… I believe it went to DMax in the end…(?) since the holes are in the rib… the rib’s strength is important… Making the holes larger… probably has a set of mechanical engineering rules to contend with… Making more holes… will have a different set of rules… but copying the holes and their separation may make sense… Getting a good answer to this… probably lies between the engineers at Mooney and the brains at DMax… Probably a five minute discussion amongst those guys could double your air flow rate out of the system… Proper drilling in a fuel tank environment will take more effort… PP thoughts only, we have discussed drilling holes in the fuel tank before… M20S long fuel neck challenge with Cris back in 2011…. Best regards, -a-

If you get the chance to see a Bob Kromer presentation… Do it!!! He gave a great presentation at a Mooney Summit a couple of years ago…. Giving great insight on climbing out after T/O… Best speeds to use in case turning back, engine out, is needed/wanted… Bob really knows Mooneys!!! I bought my M20C right after he wrote a few pages about the M20C in the MapaLog…. It was a great what to look for, and how you know the M20C is right for you… when buying an M20C…, from an engineer’s point of view… Printed late in 1999? Best regards, -a-

M20K tanks with Monroys have a complex arrangement of tank locations, forwards and back…and separation from outer to inner tanks…requiring tubing connections…(?) Probably have a couple of sump drains on each wing to go with that… similar to the pair of fuel caps… PP fuzzy memories at best… 130g Monroys in an LB are a much more simple geometry… Best regards, -a-

Getting air to flow upstream takes a few minutes… The rib vent holes are pretty small, and the full rate of the fuel nozzle is quite high in comparison… To load more fuel than ever… find uneven ground… just remember, you have probably entered test pilot territory with this maneuver… Best regards, -a-

From the other thread today… 5) When sumping fuel out of a C152… the training was to vigorously sway the plane on the ground… the large motion of the fuel in the tanks would better move water out from its hiding places where gravity could then move it towards the drains… Ever try to vigorously move a Mooney on the ground? Try it with an LB full of fuel… Best regards, -a-

Some oddities in water collecting… 1) Somebody today reported possible blockage of the rib holes that drain fluids from the far reaches of the tanks to the wing root end of the tanks… 2) If a bad seal job blocks these holes… a significant amount of water can be held on the uphill side of the ribs… 3) Change of attitude… will surely allow the water to move around… 4) Usually, nose high… will have the water collecting towards the trailing edge… where the fuel pick ups are physically located… 5) When sumping fuel out of a C152… the training was to vigorously sway the plane on the ground… the large motion of the fuel in the tanks would better move water out from its hiding places where gravity could then move it towards the drains… Ever try to vigorously move a Mooney on the ground? Try it with an LB full of fuel… Best regards, -a-

Each rib has several holes at the top and bottom of the ribs… Air has to move… as well as fuel has to move through these holes… If your resealer is unfamiliar with Mooneys…. You probably got the holes filled… They are easy to look at and clean out… Otherwise…the fuel is going somewhere else…. don’t trust the useable fuel numbers until you know all of the fuel is actually useable… PP thoughts only, not a mechanic… Best regards, -a-

1) One was cognitively overloaded… 2) The other one got caught being self centered… 3) Nobody likes getting caught being either… 4) How they react gives insight into their soul… 5) How we react gives insight into our own souls… 6) It’s not always easy to be able to say the right thing after all of that… 7) Sometimes being quiet is the best some can do… 8) I lose control at the keyboard, under less stressful situations that…. 9) Its fun when you have the experience bucket more full than empty… 10) Thanks for sharing your experience… My home drome has plenty of training going on especially on weekends… Best regards, -a-

Hence the well taught… Trust your instruments!!! It must suck when you can’t trust your instruments in IMC… It is a bit discomforting when your eyes and inner ears are in disagreement… Suddenly, two AIs isn’t enough… a third would be required for the tie breaker… Best regards, -a-

Let’s invite Chris… @Fly_M20R He has made a few nice videos regarding his O, and the GI-275s… Best regards, -a-

Runaway trim??? That can end disastrously… We lost ‘snoopy’ an M20K, fortunately pilot and copilot are still with us… Snoopy lost its trim in a nose low situation… Lots of exhausting arm strength required to maintain control… Snoop lost the battle on the runway pavement… Scary situation… Also a good reason to have those color CB identifiers… Best regards, -a-

I probably mis-described what occurred… There was a spiral… as 1980 graciously posted the WAAS data from the last few miles of the flight… And the wings would not have folded if they were stalled… (how maneuvering speed gets defined) What could cause the graveyard spiral in this case? If you fall asleep while flying a Mooney with the wing leveler off… the plane will gently lower the wing with a heavier fuel load in it… (depending on how big the fuel imbalance is) as the wing dips, the plane starts turning towards the lowered wing… as the turn continues… the wing goes lower, and the turn tightens… as the turn tightens, the vertical lift, becomes more horizontal, and altitude is being lost at an accelerating pace… But, being asleep is required for this to occur…as described above. PP question only, not casting aspersions on the il-fated pilot… Best regards, -a-

Often around here… You will probably see a ride share request between MSers going to and from distant maintenance shops… Depending on how maintenance hungry your bird is… It may be a good idea… to offer a ride… before you need one… Join a local flying group as well… there is so much you can learn about safely navigating your local area and what is on the mind of pilots in your tri-state area… Best regards, -a-

Rich mentioned something yesterday… Things you notice when you are ‘one with your plane’…. the more you know about your plane… the more you will notice when it does something a bit funky… Transition Training is a great way to get started down the right road… Mooney Specific training continues… available four times each year, known as the MAPA PPP…. You learn more about its mechanical innards by participating in its annual maintenance… Getting service while on the road…. A cell phone and MS can work some magic… There is also a service called Savvy that is worth looking into… Getting that first year out of the way is critical… A problem free first year is magical… A stuck valve during transition training leaves you a bit uneasy about what the rest of the year is going to bring… If you know what you are doing… you buy your last plane first… If you are young and short on dough… it is really hard to buy your last plane first. If you pay for your girl friend’s rent… you will know what it is like rent a hangar for your plane… Your plane will never be jealous of the money (or time) you spend on your girl friend… Around here… some people have purchased an M20C early in life… and updated it into a forever-plane over time… Sometimes plane ownership fits in between other stages of life… Get plane before… getting a dog getting married getting a house having a child before getting day care bills before getting college bills before retiring before getting that hangar with an attached house before you turn 80 Holding a plane through all of these bumps in the financial road is an interesting challenge. There will always be new jobs, raises and promotions, and recessions and market crashes… The sun always comes up the next day… Some people have a five year plan… Some Mooniacs financial plans may be longer than five years… How far out can you see your future? Best regards, -a-

An example to keep an eye on… The V-tail Bonanza has been coming up against the grim reaper for some time… Their magnesium (?) skinned tail feathers seem to be out of production for some reason… Making hangar rash a death sentence… The B-society has been offering rewards for a solution… I don’t know the status on this debacle lately… Sorry to the brand B guys if I have all of these details mixed up. Best regards, -a-

Great follow up! ReconMax. Fantastic pirep for DMax and co. Great pics of the Predator! I think the wing may have been swapped for a more docile, less aerobatic wing…. Standard Mooney issue… (?) Best regards, -a-

Especially during the winter months…. Good seals keep a puddle of water around the cap’s flap (handle) Water can freeze keeping the handle from operating… If it rains, and no water is puddled up around the handle… Be sure to sump, because that water went somewhere… Probably time to get a new small oring for the cap… Best regards, -a-

Nice follow-up Maxx! Thanks for sharing it… Best regards, -a-
