A YouTube channel I frequent, hoping to NOT see my Mooney friends making the news… The YTer is Keoni, an AARF fire fighter at an airport in Hawaii… prayers for the lost and especially, the injured airman… Best regards, -a-

Hey all! Quick refresh on the topic… The O is in annual, needs ELT modernization. options are… 1) Artex 345 2) ACK E-04 3) Kannad Integra 4) want to have 406mhz, 121.5, and GPS data connected to it… - I believe the old one is an Artex. - there is a GDL52(?) mounted on the shelf in the tailcone. (GPS data for the older BK X-ponder) reusing old footprints would be nice if able. expecting to replace all of the 30yr old equipment. as usual… plane is 1kmi away from me, unable to look what’s there… expect Mooney standards for 1994… Thank you for the words of advice! Best regards, -a-

One thing for sure… if you have learned to use a certain amount of prime in warm weather… and the temps have cooled a bit… less prime won’t make any sense (to a chemical engineer). 100LL is known for its inability to evaporate as temps cool… the IO550 uses 40°F as the cut-off from normal start to cold start… where additional seconds of prime are used… and running the fuel pump on Lo to keep it running for a few more seconds… read up on various starts to understand them better… as a flooded start may be in your future… Best regards, -a-

Fresh out of annual? Fresh grease gets pushed into the hub causing some to escape out the seals… deep cycling the prop? another reason some grease may get past a seal that has been sitting awhile… when grease comes out three inches of prop blade… it will leave small bits of grease on the windscreen… a clean windscreen is required to see it… let’s invite… @Cody Stallings for some insight on prop grease leaking… Best regards, -a-

Nice work AV! thanks for sharing. the mechanics of buying a plane have never been easier… With MS, we collectively either know the owner, or the plane, or can have somebody Knowledgeable put eyes on it for us… getting a decent PPI is a known part of the game… MS even has an insurance guy around here somewhere… Transition training is the next fun step! PP thoughts only, not a CFI… Best regards, -a-

I followed your logic up to the last sentence… An updated M20E makes a great retirement plane… Speed, efficiency, and a great instrument platform… for two. ”don’t need a long body… would rather have the speed…” last I checked… all long bodies are much faster than all short bodies… add a pair of TNs… then you have reached ludicrous speed in the FLs for two… with 1knms range… this is often the last step prior to going turbine… this could be explained if comparing an M20E to an M20F… the F, is a mid body… sharing the same IO360… Best regards, -a-

One change for M20Js showed up with the shaped wing tips… and… rounded corners on the side windows… And… matching interiors to windows… the latest interiors were fabric covered molded fiberglass… the 70s M20Js… were very 1960 Mooney… the 90s M20Js… were very 90s Mooney… extra care should be taken to know what the MGTOW is… it directly affects the UL… a few of the structural Tubes were changed to support this.. The separate mags are nice… roller cam followers are cool too… the best part… they all fly the same, unless you got the Rocket Engineering STC… 300hp makes a real difference… go Missile! PP thoughts only, not a plane sales guy… Best regards, -a-

Has anyone had an io550 rust problem? I haven’t seen any yet. plane lives in nj, indoors, not climate controlled… best regards, -a-

Six parts to this challenge… (1) interest rates have peaked over the last year making finance more challenging… like home sales… increased interest rates really contain the price from increasing… (2) Supply… they aren’t making any new ones… (3) Demand… M20Js are an easy transition from the trainer world… M20Ks are a two step transition for most people. First step, fly a Mooney…. Second step, fly a TC’d Mooney in the FLs… short body Mooney’s cost as much as another car… Long body Mooneys cost as much as another house… 4) Long term concerns… Factory in existence… fuel availability… 5) Cost of getting a license is a perennial concern… Are there fewer pilots graduating into the ownership ranks? does everyone insist on having a parachute or something not available as a retrofit…? 6) number of children still living in your house… my long term plan to not lose money on the sale of my forever plane… My estate sale is going to be epic! a fully worn out plane and a fully worn out house… Best regards, -a-

Switches often wear… they are designed with an over center bump that keeps the either opened or closed… as they wear, they can easily be bumped and switch positions… I haven’t seen one physically switch, but not change the open/close status… in this case… it sounds like the switch is operating correctly. But, the next device in line is probably not… master switches are not as complex as the CB switches that carry more load… PP thoughts only, not a mechanic… best regards, -a-

Roughly speaking… max FF is about 2X cruise FF… if your io360 is cruising using 10gph, it’s full rich max FF will be near 20gph… same for the io550… 15 and 30 gph anyone with a Missile using 2700 rpm… can easily benefit from moving the FF towards a higher number. the ovation uses 2500 rpm and 25 gph (?) the Standing O uses 2700 rpm and enjoys 30 gph… the excess FF goes directly to cooling EGTs and CHTs excess FF to a cylinder can affect the A/F ratio too much.. causing misses and washing the oil of the cylinder walls…. we are supposed to follow official documentation for setting FF. But, sometimes the documentation is in error, or not updated… check with your mechanic on how to handle increasing FF… PP thoughts only, not a mechanic…

When we want to know why one cylinder is running hotter than the others… if we have a FF gauge, we can run a Gami spread test… if we don’t have a FF instrument.. we can run the test, but may not get enough detail… if air is leaking into a cylinder, or an injector is clogged… the Gami spread will usually point it out… lean slowly while approaching peak… if things misbehave early on… there is something wrong feeding that cylinder… probably not a cylinder issue. For that we have small cameras… pics of valves and cylinder walls are cool! PP thoughts only, not a mechanic… best regards, -a-

Cool! electro mechanical actuators… if your dishwasher is leaking. It has a solenoid valve that is supposed to be NC when the washer is off… (valve closed) similar with the clothes washer… one for hot, one for cold… but, I digress… the Mooney Parts Catalog calls them Relays… shorter, easy to spell, takes a low current signal to quickly switch a high current source… it sort of relays the pilot’s intention… The pilot activates a nice labeled switch on the panel, that activates a big switch close to the device. many pilots don’t know what the panel switch is actually doing… great tech conversation… best regards, -a-

Also… add to your checklist… walking away from the plane… always look back to see the red flashing strobe isn’t operating… could be a memory issue, or a worn relay… Best regards, -a-
