Mooneys overrepresented in gear ups

Do all Mooneys have a gear alarm?

Yes, at least all electric gear Mooneys do. Gear horn is supposed to be checked during preflight.

How do you check the gear horn in preflight?

There is no pre-flight check other than the pre-landing check; only an annual/100hr inspection test on jacks

You can check the gear horn inflight by pulling your throttle to idle and having the gear up. Some are activate by MP over like my S are activate by position of the throttle linkage. Sorry if this has already been mention. I read over the thread quickly.

Many Mooney's have speed brakes. Speed brakes can inadvertently cause gear up landings for 2 reasons. 1. Give you the sensation of the gear being down and 2. Require to advance throttle overcome the drag on final to deactivate the warning. This can be an additional reason Mooney's have a higher incidence of gear up landings.

There is a test button on the electric gear that tests the horn

Robert, got a picture of the button?

I'm not sure on this one...

Haven't heard my gear not down warning in a while...

Would love to add it to the pre-flight,

Best regards,

Here is a picture of it on an F I found online. Its a good thing because the sonalert gear horn is fairly unreliable in my experience vs the stall horn.

been in a lot of F's and never seen one, or heard of one till now,  sounds like a mod. Got any more info on this? would like to learn about the details.

I've flown a number of F's, E's and C's and haven't seen one without  it. This picture I randomly found on the internet.

Then it should be in the POH, but looking at a later '75 M20F POH I can't find any mention it.

All it says at 2-8 and 7-8 is that the horn sounds with a MAP of 15" or less if the gear is still up. Nor does it show button for it on the panel page that list everything installed by Mooney. Perhaps a Mooney approved kit modification?

There's not one in my electric C, nor the electric F that I have a dozen or so landings in. Never heard of one until just now.

Some do have ever an override button of some sort, tied into the airspeed switch that is intended to prevent inadvertent retraction, I think . . .
