We sent the actuator off to be looked at and got a "there was nothing wrong with it" report back. Everything including the NBS were checked and completely normal. They completed a service bulletin of some kind and did replace the emergency extension pulley as there were some indications of wear there that weren't up to snuff. We put the actuator back in the airplane and it worked normally. Several flights later - no issues. We also had our mechanic replace the CB as it had been tripped many times in all this and is 35+ years old... I'm guessing it was an issue with the emergency extension engagement mechanism. But our mechanic said he checked that... Who knows. Anyway, it works now! That seems to be a common result with gear issues. Gremlins. I had a similar experience a few years ago… Quote
PT20J Posted July 12 Report Posted July 12 Probably a relay or microswitch. It will continue to work until it doesn't and then you can find the bad part. Fortunately for me, when that happened both times were close to home base. Plane flies really slow with the gear down 2 Quote

Seems to be the guru on these things. https://lasar.com/ Possibly that’s true, however I talked to them when I was at Prineville after they moved (last year) and none of the mechanics had moved from California, and the Oregon ones had plenty of experience but none specific to Mooneys. I would still use them (my own shop isn’t an MSC either), but I wouldn’t assume they have any special experience. Maxwell and a few others still do, not that it’s required for most maintenance, but maybe for something like this it’s useful. 2 Quote
