It can be wet or icy outside our hangar so we got an AeroTug. Not at all portable, but it's a beast.

I'm pretty sure the throttle cable was the OEM from 1962. With 4000hours and the hole for the gear warning, I'm sure crap got in there little by little. Of course it could be fatigue. It has started to fray and my guess is that years of pushing full throttle took their toll. Probably more likely than contamination. ...and lube won't help. It was the last thing I fixed before handing over the keys and getting our M20M. I did however go flying with the current owner last week.... nostalgia.

I was told after the fact, that lubrication should not be used because it attracts particles and keeps them in the shaft. If there is no lubrication and it becomes difficult to move, that means it's beginning to deteriorate and needs to be replaced. Application should be used, in this instance, wink.

I'd just pay for the repair and keep my insurability in tact.

For about a month we started noticing the throttle becoming a bit harder to move in and out on our M20C. We thought, we'll get to it shortly at annual. And then on one flight it got real sticky. Upon landing and taxi it wouldn't advance, so I slowly limped back to the hangar at idle. Upon further inspection you can see how bad the cable had frayed. Lesson: If something is a bit wrong, get it fixed or looked at...it will only get worse, not better. (could have happened in flight)

There are dozens of systems and sources depending on the phase, criticality, and type of system. It's a complex challenge in both civil and military applications. Each has different failure modes, finding the right mixture at the right cost leads to some fun engineering.

Currently the FAA only allows certified NAV systems to use GPS, however, GALILEO is nearly in the regulations, so expect that to become available in the next few years. (part of why I'm holding off on avionics upgrades...it's a HW change). Consumer devices and handhelds can use a multitude of GNSS signals. GPS, GALILEEO, GLONASS, BEIDOU. There are also regional signals like QZSS. Newer phones also use L1 and L5 frequencies from GPS and GAL, some also have BEIDOU. Most of the constellations have multiple frequency bands to help with interference/jamming, atmospheric delays, and mulitpath. https://www.tallysman.com/gnss-constellations-radio-frequencies-and-signals/ When one tests jamming it could be multiple types of tests as people mentioned. It could be broad spectrum, specific bands, or constellations. It depends on what offense/defensive solution is being tested. One can also be testing directional antenna solutions like CRPA to null out a jammer or spoofer. Having a tablet with GNSS, not just GPS, and VOR capability in the panel is a great backup. Jamming and spoofing are not the only challenge for GPS/GNSS. The signals can be blocked by buildings and terrain. That's not an issue for Mooney pilots, but is an issue for drones, air-taxis, cars, and anything on the ground. There is now technology that can predict GNSS conditions to route around denied areas, or improve performance by enabling the GNSS receiver to prioritize the best signals. https://www.spirent.com/products/gnss-foresight-forecasting

We bought a https://www.amigoaerotow.com/ . It's a beast. It get's our heavy M20M over a few bumps on the way into the hangar.

LOL. You may be big, but I'm ahead of you.....

Did a similar thing last year, but went in the other direction of getting a more capable bird. My partner bought me out of the M20C so he could enjoy pre-retirement as an empty nester, and I moved into a M20M. I'm a bit envious of the new opportunities the Taylorcraft will open for you. Have fun, keep the greasy side down.

@LANCECASPER Do you have a copy of the Garmin service bulletin on the GFC500 servos? A friend of mine has been battling that issue for over a year with him M20J, I hope finally resolved. @chan65

And then the mirror falls off in the cylinder when using the cheap ones. Ask me how I know!

It's another thing to maintain. Unless you are going to use it as a primary trainer, I wouldn't.

I've been waiting for a reman from the factory since August. You might figure that into your timing. If you need 12mo to get the cash, it'll be another 6-8months until you get things done and billed.

Done!

Anxiously looking forward to dropping of our 1993 M20M Bravo for it’s first reman since new. We’ve been waiting for the engine since August! A lot of other items to be addressed while Oasis has it. Following advice of many here to have either Oasis or Maxwell to do the work given the complexity of a Bravo. …and she hasn’t been to a Mooney Service Center since the 90s…worth having an experienced eye make sure she’s like new. Anyone up near Willmar want to fly me next Sunday from Willmar to Minneapolis? From there I’ll catch commercial to flight back to Indiana. Thought it might be an opportunity to see another MSer.

This document predates the Bravo....so take it with a grain of salt/lead.

That's what we've done for a long time.

Young love. Just be sure you know who you love more ;-)

That is the first time I have ever heard that advice. Not saying it is wrong or right.

Has anyone removed their co-pilot seat to make room for additional cargo? Wondering what the weight is, I couldn't find it in the POH or SM. I assume my A&P would need to do it and sign off on a new W&B.

Like you said, that sounds like a mag issue then.

Are you sure it's the mag and not one of the plugs gone bad? I had a similar problem last week (also expecting a new engine soon). The engine was rough and the EGT on #3 dropped when on the left mag. I was able to replace that plug and the problem went away. (sorry if this is obvious part of trouble shooting, people have different experience levels.)

We're about to get (knock on wood) our reman from the factory. I was thinking about the same thing...run the massive plugs for a few hundred hours and then put fine wires in. Ironically we had the existing massive plug on #3 lower go bad last week. I replaced with a new plug just so we can fly her to the shop for the new engine.

Funny! We used a hex wrench as a replacement for years. ...and still carry the vice-grips just in case.
