I am getting an intermittent Gear Up light failure on my right gear. Initially on retract, I get a solid red, then it blinks for a few cycles, then goes out. Bulb test shows all lights working, and I get the indication in both cockpits

Is this a latching problem with the gear up lock? Switch fault?

I will have it up on jacks this weekend, so anybody have any advice on what to check?

Thanks
Ed

Check the engagement "button/arm" adjustment that depresses the
microswitch.?? Using a flat blade screwdriver with someone in the
cockpit, depress the microswitch button and see if the light is
flickering when you first engage the microswitch manually.

I agree with Dennis in testing the switch.  
One question.   When you put your gear up.  Do you leave the gear handle in the up position.  Or do you put it in the neutral position?

Thanks for the great tips.

Jon Boede and I worked on the plane yesterday, and we may have found the problem. The switch is held to the mounting bracket by two bolts, and the bracket is held to the plane by four bolts.

One of the two switch bolts was missing, so that was fixed. Jon also adjusted the switch end point. We will check it out during gear swings next week.

To answer Dennis' question, I leave the gear handle in the Up position the entire flight until preparing for landing.

Thanks again!
Ed
