I am having an issue with the gear warning on my 1979 Mooney M20K. I recently had a new Garmin autopilot and 2 G5s installed. When I picked up the aircraft, we had an audible gear warning after takeoff and the gear would not retract. The shop pulled it back in and checked it out. They added air pressure to the pitot tube to check the airspeed gear warning switch. There were no broken or loose wires however they were able to resecure the wires near the airspeed indicator. I am having intermittent issues with retracting the gear after takeoff. Last flight, I had to cycle the lever twice to retract the gear. First time, audible warning so I put lever back down. Then tried it again and gear came up. Does anyone have any information on a part number for the airspeed gear safety switch? Is it part of the airspeed indicator or attached to the airspeed indicator? I have attached a picture of my airspeed gauge for reference. I am trying to gather some knowledge before taking it to a shop. The aircraft is at KVJI in Abingdon, VA. Thanks in Advance, Gary

After my 1974 M20F came out of annual, the gear warning system was now functional. It had not been working for the 6 months I owned the plane. However, I found that in flight as soon as I pulled the throttle back to below 22-21 inches, the gear horn would go off (it should go off maybe 10-11). This system is different than other gear warning switches I've seen on Mooneyspace which looks like a switch on the throttle cable which can be adjusted along the cable. On my 1974 F, it is a switch and arm inside the throttle quadrant. The switch (best seen in IMG_2614) has a metal arm that extends out and rests on a small adjustment plate (IMG_2615) with a tip that catches on the plate (IMG_2613). When the throttle is forward, the plate puts pressure on the metal arm which depresses the red button. As the throttle is pulled back, pressure is released and at a certain point the "cupped tip" of the metal arm is lifted by the friction of the adjustment plate. The problem is that the pressure and lifting of the metal arm happens almost immediately (about 22 inches). I have adjusted (under supervision of the mechanic) the plate all the way forward and all the way back by loosening and tightening the nut (IMG_2615), with very little change. The horn comes on about 22-21 inches. I have adjusted (slight bending) the little metal arm, but that doesnt work either. If I adjust it too much, it loses all connection to the throttle arm and adjustment plate. I'm almost wondering if the metal arm is broken and may have been longer at some point. Has anyone worked on this part before? Could it be that the little "cupped tip" on the metal arm should actually be longer and extend UNDER the adjustment plate to give the ability to actually adjust it? Right now the cupped tip catches on the adjustment plate and relieves pressure very quickly, whereas if it were longer (extending beneath the adjustment plate) would give the ability to adjust the actual pressure on the metal arm versus having it snag and be pulled up by movement of the throttle lever. Sorry, a little complicated and probably using wrong engineering terminology, but if you've seen this before and can tell 1) whether it can be adjusted as is or 2) the arm is actually broken, I'd appreciate it. Thanks!
