Teddyhherrera Posted September 15, 2022 Report Posted September 15, 2022 In my recently purchased F, the trim and indicator need significant adjustment. In full back trim, i still descend at 90 kts no matter how i try to slow it down. I can just open it up and readjust it but I'd like to adjust it to factory specifications. Is there a way to do this without jackstands and that weird wing tool? Quote
Shadrach Posted September 15, 2022 Report Posted September 15, 2022 There are specs for the trim position outlined in the Maintenance manual. You cannot simply customize it to your liking. What RPM does your tach show with the throttle set to idle during ground ops? What does the trim indicator show when the trim is set full aft? Quote
Jpravi8tor Posted September 15, 2022 Report Posted September 15, 2022 I too am curious at what power setting and flap position results in a 90 kt descent rate? Quote
carusoam Posted September 15, 2022 Report Posted September 15, 2022 The best charts for Mooney performance figures and configurations is produced and handed out at MAPA PPP classes… Attend the class, and get the most complete performance book ever printed… Best regards, -a- Quote

Is there a way to do this without jackstands and that weird wing tool? This one needs a little more help…. Are we talking trim indicator… Trim… or WnB… Most often, new owners find their trim hits the stop…. But doesn’t seem to be fully trimmed…. (Sound familiar?) Open the access panel to find out what is going on… often… the grease being used turns to rocks over the years… Chances are… the trim isn’t hitting a stop… it’s hitting a stone…. Clean out the old grease… fill in with new grease…. There are both a gear box and a Jack screw back there…. Same grease. The Jack Screw is an easy place to start… Next step… the indicator is not a very robust system after several decades go by… check to see if it is working properly and the pointer is still in place… many pointers go missing… PP thoughts only, not a mechanic… Best regards, -a- 1 Quote
carusoam Posted September 15, 2022 Report Posted September 15, 2022 It is often said… You can’t get enough trim in a Mooney… Use caution with this statement… adjust the balance with real people… you immediately find that you have plenty of trim…. You won’t want any more… trimming into a stall condition would be bad…. PP thoughts only, not a CFI…. Best regards, -a- Quote

You need to take it to a shop with the correct travel board, inclinometer, manual and knowledgeable maintainers to get this checked out. Quote
PT20J Posted September 16, 2022 Report Posted September 16, 2022 If it were mine, I’d take it to a knowledgeable Mooney maintainer with the correct tools and figure out what’s going on. The trim should never get out of adjustment unless something is broken or someone messed with it and either didn’t get the torque tube set back right or installed a part incorrectly. There are bungee springs that have to be set right as well as setting up the actuating mechanism. Since the airplane is new to you and you don’t know how it got messed up, it would be wise to have it checked out. Skip Quote

N201MKTurbo Posted September 27, 2022 Report Posted September 27, 2022 Most likely someone serviced the jackscrew and got it all out of whack when they put it back together. Where are you located? Quote
N201MKTurbo Posted September 27, 2022 Report Posted September 27, 2022 In reality if you get full travel of the trim wheel gearbox in sync with full travel of the tail jack screw, you will be close enough that it wont matter. 1 Quote
