    If you get a drawing and material specs, perhaps the best solution is a smallish machine shop. It sounds like the specialty gear manufactures are not interested in making a small run of parts once.

    Are you really sure it is spun? Those bushings are pressed in and to spin it would take a lot of torque. I've found that partially raising the gear and moving the main wheels up and down with one hand while operating the grease gun with the other will often get a troublesome zerk to take grease.

    It appears from the example in the Concorde document and Eric’s experience that these things go from good to bad rather rapidly. Maybe it’s just smart to just replace every 4 or 5 years if you fly IFR in a predominantly electric airplane.

    Do you have pictures?

    I’d contact Frank Crawford at Mooney. fcrawford@mooney.com

    I emailed my Lycoming rep and got this reply: "If it is the video I’m thinking of, it was posted by a company that used our video content without our permission and generated captions throughout that was spreading inaccurate information. All videos posted directly from our page have the accurate and Lycoming specific information that was falsely discussed in that video, please enjoy any of our uploads! Thank you for reaching out." Lycoming's Youtube page is: https://www.youtube.com/user/LycomingEngines

    Also keep in mind to quote W. Edwards Deming, "There is variation in everything." Some batteries are just going to last longer than others. Everything is on a bell shaped curve.

    The answer, as you might expect, is, “It depends.”

    It turns out that Concorde has Technical Bulletins discussing adjusting capacity check intervals and maintenance charging. https://www.concordebattery.com/knowledge-base.html?media=tb

    Thanks, I should have mentioned that.
  11. PT20J
    Agreed, but not that hard if you charge it immediately after the test. It’s a tradeoff. I wouldn’t do it monthly. But maybe 6 month intervals would make sense.

    I think most building codes only require gas water heaters to be 18” above the floor due to the pilot light. Seems like requiring the refrigerator to be 18” off the floor is overkill, but my hangar has that reg also.
  13. PT20J
    I think the idea is that if someone has a fuel leak, the fuel vapors are heavier than air and so will be near the ground. So, keeping any potential spark producing equipment 18" above the floor might prevent ignition.

    Inboard senders are accessed from the cabin. Outboard senders are accessed through a removable panel outboard of the tank. No need to unseal the tank.

    That’s an interesting result. Of course, the capacity check only serves to indicate whether the battery can be returned to service as of the date of the check. Since the checks are recommended to be performed annually, I always assumed that the battery would degrade slowly enough near its end of life that it would not fail completely within a year after a successful check. I wonder if it might make sense to do more frequent checks after a few years of use?

    It's not Mooney specific. It's a Lycoming spec. Reference Lycoming SSP-1776 Table of Limits and Torques. You turn the plug until the surfaces meet and then tighten by turning an addional 135 degrees.

    My IA says he has had stainless screws gall and jam in nutplates and now he puts anti seize on them. I’ve never had an issue. Has anyone else had issues with stainless screws galling?

    Does the airplane sit outside a lot? You could also try putting some aa ACF-50 on the threads.

    Like Don, one of my most “interesting” flights was with a salesman. I only got St Elmos fire on the windshield once — years ago over the Woodside VOR heading for SJC. I was in the clouds in heavy precip but there were no thunderstorms around thankfully. That was in my 1978 J with no static wicks and the coms were fine. I didn’t try the ADF.

    KAP150 Pilots Guide.pdf Sonalert is in the overhead. You should also hear it when you disengage the autopilot. If not, I’d check the sonalert.

    Jacks

    PT20J replied to a topic in General Mooney Talk

    All the jacks have a spherical cup. This is to allow the jack point to freely rotate as the angle changes when the wing is lifted. They will work fine with the Mooney or LASAR conical jack points.
  22. PT20J
    My 1978J didn’t have them. My 1994J does. I’ve noticed no difference flying lower altitudes in precip. YMMV.
  23. PT20J
    I believe they were an option. Probably most helpful with ADF. The last time I replaced one it was hard to find the one Mooney used. I notice LASAR. has the 4” for $75 ea. Personally, I wouldn’t replace them.

    Be careful if you ordered one of the pre-packaged screw kits. I found that some of the screws were too long. In most places it doesn't matter, but there are a couple of inspection panels where screws longer than called out in the IPC can damage control push-pull tubes.
  25. PT20J
    You can get the service manual including the schematics in pdf form from Mooney. I got mine directly from Frank Crawford, but I'm not sure if he can still supply them or if you have to go through a MSC. The relay that controls the battery circuit is near the battery in the tail. Easy to check it's functioning with a voltmeter.
