At the end of the second leg of a cross-country yesterday I moved the landing gear switch to "Down" and nothing happened. I toggled the switch a couple times and got nothing. No motor motion, no circuit breakers popped, the low RPMs gear alarm continued (along with airspeed...), the "Gear Unsafe" annunciator light was lit, and the floor window showed red-stripe gear up. I lowered the gear using the manual extension and landed safely. Luckily, the issue happened at my home airport, so there's that.
Ahead of the troubleshooting on jacks with my mechanic tomorrow, I thought I would solicit info from anyone with prior experience on this issue. Areas I assume we'll look at: actuator motor, breakers, relays (one for up, one for down), any loose wiring. (I did have some rain and turbulence on that leg.)
(Side note for others: when you lower the gear via manual extension, be careful NOT to over-pull that ripcord cable. Lower the gear until the Gear Unsafe light goes off and you have normal green in the floor window, and that's it. If you force-pull the cable after you have a gear-safe condition, you will bend the long linkage rod in the belly. I almost learned that the hard way in a hangar with the plane on jacks a couple years ago.)
