Gear doors not closing on gear extension.

Also check the connections going into the hydraulic pump. They tend to get loose.

It's been a few years, but as I recall,
the system is designed to prevent doors from closing
until all the microswitches confirm the gear is fully locked either up or down.

I vaguely recall an issue like that many years ago:
The micro switches that detect full uplock position were not fully closing,
so it would prevent the gear doors from closing.

Q-Does your uplock light come on? I THINK that requires all uplock switches closed.

Open the doors on ground w hand pump.
"Circuit open (power off), doors open"
"Circuit closed (power on), door close"

Look for the uplock microswitch for each leg.

Press each w finger for affirmative tiny click.
Spray (FAA certified and approved) brakeleen, or equivalent into and around switch.
That will clear (FAA certified and approved) dirt / snot.
Until you feel a nice clean little click when you press.

The airframe uses common industrial (aka 'digikey) microswitch switches.
They are easy to find replacements if needed.
