Gear Actuator Breaker Pops

[Hugo Gross]

A few days ago we took off and retracted gear and then in the middle of the flight the gear actuator circuit popped. The manual gear latch was closed and it popped when there was no apparent load on the motor. The breaker would not go back in. We manually dropped gear and took it to mechanic who could not find anything wrong. The breaker went back in and there have been no issues for 14+ takeoffs and landings. Then it happened again. Gear came up normally then in the middle of the flight it popped about 10 minutes after takeoff and when we landed the breaker pressed back in and stayed and it hasn’t happened again. I am wondering if it could be something to do with the gear up limit switch. Maybe the motor brings the gear up occasionally then doesn’t shut off which leads to the breaker popping. Has anyone had this happen and any ideas? Thanks!

I'm no mechanic, but this sounds like a plausible explanation.

That sounds plausible to me, too.   Once the belly is off that switch is pretty easy to get to to check wires, etc., or to just swap it out.
