Let's look at some stall speeds and characteristics in the J model. Stall speeds are quite low in the J model. Lots of pilots think that the J model is a "hot" airplane with high stall speeds and harsh characteristics at the stall. Not so. We found that N531DD stalled at 58 KIAS/67MIAS gear down and flaps up and at 52 KIAS/60MIAS with the gear down and the flaps full down.

Using the stall speeds derived above, let's set some approach speeds and shoot some landings to get a feel for the airplane in the pattern and in the landing flare. Using our old rule of multiplying the stall speeds times 1.2 to determine "over the threshold" speeds, we come up with 1.2 times 58 KIAS = 70 KIAS with the flaps up and 1.2 times 52 KIAS = 62 KIAS with the flaps full down. I know these numbers sound low -- they did to me. But let's try them out in a series of landings.
I like to fly the pattern in a J model at 100 KIAS. I use this speed for my climb, crosswind, downwind and base. On final, I begin slowing to 80 KIAS and am at my targeted threshold speed of 1.2 times the stall speed as I enter the landing flare... I next tried the targeted threshold speed of 62 KIAS over the numbers with the flaps full down. Again, perfection! Good energy left for the flare and touchdown. At no time did I feel the airplane was going to fall out from under me.

Regardless of the type of Mooney you fly, try finding out what your threshold speeds should be in this same manner. Go up to altitude and do some stalls with the gear down and the flaps up and the gear down and the flaps down. Note the indicated airspeeds where the stall break or buffet occurs. Multiply these indicated stall speeds times 1.2. Use the resulting speeds as the target speed you want to be at as you cross the numbers and begin to flare the airplane for landing. We're having way too many landing overshoots and prop strikes in our ranks these days -- all the result of excessive airspeed during the landing flare and touchdown. Get those speeds in check. It's okay to fly the pattern at any speed -- I like 100 KIAS, slowing to 80 KIAS on final. But those speeds must be slower as we begin our landing flare. So determine what the indicated stall speeds are for your particular airplane at the weight you fly the most, multiply them times 1.2 and set that as your target speed for beginning the landing flare. Your landing distances will be shorter -- guaranteed. Your landing gear maintenance will be less -- guaranteed. And the chances of the airplane porpoising and getting up on the nose gear during the landing will all but be eliminated -- saving a very expensive engine/propeller replacement if you should have a prop strike.
