Lood Posted August 20, 2010 Report Posted August 20, 2010 The landing gear warning alarm in my Mooney has been sounding permanently during the last couple of flights. It used to work fine and only came on when it should. I'm not sure what is causing the current situation, but it starts up immediately after I retract the landing gear. I've been silencing it during flight by lifting the little switch arm inside the gear-down socket and keep it in place with a rolled up piece of paper. Before I lower the gear, I just remove my custom made alarm silencer. Does anyone have any advice on where to start looking for the cause? My common sense tells me that somewhere under the panel, there must be some sort of switch that is activated by throttle position or something, but I haven't had time to stick my head in there.
KSMooniac Posted August 20, 2010 Report Posted August 20, 2010 My J senses off the throttle position using a bump to close a microswitch. Not sure if yours will be similar, but it should be easy to check visually after you contort yourself under the panel. Perhaps your microswitch failed?

Lood Posted August 21, 2010 Author Report Posted August 21, 2010 Thanks to all for the replies. It is indeed the switch and I have adjusted and retightened it.
