The Beech 1900 landing gear is mechanically locked down with a spring-loaded snapring and ball bearings to lock the ball bearings in place. It shouldn't be possible to retract the landing gear on the ground if those snaprings/ball bearings are in place even if the hydraulic pump is pressurized due to the landing gear geometry. Also a squat switch prevents the landing gear handle from being actuated on the ground. I suspect that the culprit was corrosion in the mechanical downlock mechanism.

Classified by many as a bottom feeder, the piranhas attack GLA quickly any chance they get.

Yea, well tell them to attack this: One of our pilots enroute to Farmington overhears a cirrus pilot barely making sense over the radio. The pilot passes out and the passenger gets on the radio (not a pilot). The GLA pilot talks the passenger through descending the aircraft to a lower altitude. The cirrus pilot wakes up, takes control and lands safely. A positive ending to what may have been disasterous. Sounds like the passenger was pretty wacked out and the GLA guys almost had him pull the chute.

I thought there might be other factors at play behind some of the past comments. I would think that ANY company had better have their maintenance records in order after a mishap for instance.

Both j hook and the squat switch should prevent one from even pullin the handle up while taxing , that is even if they wanted too. Then you would get that annoying gear silence horn. '!!!!!!

When are the feds going to shut that place down? Those mechanics "Ops check good" everything from alternate gear extensions to autofeather failures to you name it.
