Had exactly the situation with the microswitches Nil defects mentions. Set like a hair trigger and happened twice no less on a departure out of Copenhagen.

Third time the lever went to off I was in full Steve Austin slooooow motion mode. Oh, and it is a very noisy shock even the second time........

Hello friends,
I would like to make a suggestion here. When putting the gear lever from up to off, take the handle out of it's detent, slide it down slightly, release it, then slide it down until it slots into the off detent. This way, it will not go past the off detent. We were taught to do that when we were cadets doing conversion training on the B737 simulator years back and so far it has worked well.
Happy flying.

Apparently one of our senior Management pilots did this a few years ago. Hence the demo in the sim on conversion of just how little you need to go past the off position to increase the noise, both inside and out!!
