Sheared bolt on the right main causing it to fail up or down. It was just stuck mid-travel. Piper makes all their gears where the engine hydraulics keep the gear up. Should the engine fail or the airspeed drops to within 5KTS of stall speed, the gear drops on it's own. The only time this hereto perfect system becomes unperfect is when a mouse builds a large home inside your gear well. When the gear is attempted to be raised, the mouse house becomes a load inside a trash compactor. The result is bent metal.
Absolutely no criticism intended here just searching for information because I fly quite a bit in private aircraft.
So is this a case of insufficent preflight inspection by the pilot or was the mouse house completely hidden from exterior view?
