G=Gear Down
U=Also put your undercarriage down
M=Make sure your gear and undercarriage are down and locked
P=Pretty sure you still need to check if your gear is down.
 
Likely true for the remaining Mooney fleet as well.

I preach three things about retracts.
  1. A gear deployment SOP that is so consistent, it becomes an ingrained habit.
  2. Before-landing checklist.
  3. Repetition.
the closest I’ve come to a gear-up landing (so far) was about 20 years ago. I had been using the same SOP for years in every retract I flew. Then I did a flight in the same make and model I usually flew with a retired airline pilot. I liked his methodology and decided to change mine. Two flights later, the gear warning woke me up on final, #1 was the result.

Ah, yes -- the laws of exercise and primacy at work. Or as a wise person once said, "If it ain't broke, don't fix it."

The thing I picked up from then-Maj. Dave Mitchell in the F-111 at the 27th Wing at Cannon AFB was as the nose begins to cover the near end of the runway, look at the gear lights (only two in the 'Vark) and say, "Gear re-checked down." Even in fixed gear airplanes at that point I find myself looking for lights that aren't there.
 
Even in fixed gear airplanes
I'm on the fence about a gear-down check in fixed gear airplanes, unless the pilot flies both fixed and retractable gear. I see the laws of primacy and exercise as a mixed bag. Conceivably, things like, "down and welded" teaches that if you forget the gear, nothing bad happens.

Besides, given my general anti-mnemonic bias, I'd rather see the laws of exercise and primacy use to indoctrinate us into the use of physical checklists.
 
Heck, I do Gumps in my 172. I used to ask my CFII if I had a wheel on his side after looking at mine. Pretty soon, he was turning and looking without my prompt. :D

Great technique but, regrettably, hard to do in a low-wing plane.

And I couple of times I've found a bad tire that way so I can plan for a problematic landing instead of being surprised when I touch down.

I have trouble seeing something wrong with a tire not under load-they often do not look flat. Outside of noticing obvious damage to the tire or wheel ie debris puncturing it and visible, what tipped you off on observation from the cockpit that those tires could not support a landing?

Ever lost a wheel?
 
My 210s had convex mirrors on the bottom of the left wing, so you could see that your gear was down and that there was a wheel attached for both the right main and the nose gear.
 
I've heard of that for some low-wings too. It tells you down; it's not a guaranty of "locked," but better than nothing.
That takes me back. . .

In the mid-’60s I was a ground radar technician in the USAF and made numerous trips to remote radar sites in Alaska. In the process of doing this, I frequently flew on C-123, C-130, and civilian Fairchild F-27 aircraft; several times on Pilatus Porter bush planes; at least once each on a DC-3 and Lockheed Constellation; and occasional other civil aircraft.

One time when returning to Anchorage from a trip, I spent the night at Hughes, a very small predominately Native village. The next day I and the other few members of the team were to fly on a Fairchild F-27 bound for Fairbanks. It was winter and very cold. When flight time came, the pilot couldn’t find the keys to the plane which had been parked overnight but the stewardess managed to get in through a window and open the plane. Although we had to wear arctic gear when flying on military aircraft, this was a civilian flight so we had to wear our Class A dress uniforms. We did have parkas but not our fat boy pants and arctic mittens, so I remember being very cold until the cabin finally warmed up. There were only a half dozen or so passengers, and I chose a window seat a few rows back on the left. Pretty soon I nodded off -- I don’t recall the details of that particular night, but history says I was very likely up very late doing typical enlisted-man stuff. Anyway, it was getting dark very soon after as it does in the Alaska winter, and some time later I woke up realizing that the plane was circling. I could see a frozen river below and recognized it as being a common way station on the way to Fairbanks. (Tanana if I recall correctly, but might not.) As I woke I realized that there was someone a few rows ahead of me shining a flashlight out the window at the landing gear extending down below the port Rolls-Royce engine and shouting through the open cockpit door to the flight crew: “She looks like she’s locked but she don’t say she’s locked.” This was repeated a couple more times as we circled. Finally a comment -- don’t recall from whom -- to the effect that we’ve got to land one way or the other. And down we went. There was a lot of snow on the runway resulting in big icy clouds and some fishtailing as the plane came to an otherwise uneventful stop. Bags of mail were unloaded and unloaded and I saw a couple of people inspecting the landing gear. After just a few minutes we were off again.

Lather, rinse, repeat -- same routine as we reached Fairbanks -- flashlight out the window, “She looks like she’s locked but she don’t say she’s locked.” The only difference was the fire engines chasing us down the runway, but again the landing was uneventful.

Guess she must’ve been locked. Good thing, ’cause here I am telling the story.

An inexpensive tire pressure monitoring system can fix that. However, it may not be FAA approved.


FWIW:
