Hello Dom,
In our 320 and others that I've flown you either
have to wait quite a while for the mains to lock down or, more preferably, a
slight yaw with the rudder will do the trick (step on the side you want to
lock). I believe that this is normal. From your post "most likely in the air" I
assume that you haven't tried it in the air? You should. I do a free fall test
in the air about once a month. (slow down, pull the big gear breaker AND the
gear relay breaker, gear switch down, open the valve). In ours, I usually need
to "help" the right gear a little with rudder.
Yes, the nose should be first to lock. If it's
getting lazy, you're probably due for a new gas strut. This is a normal
maintenance item, I replace mine probably every 3 or 4 years. If you replace the
nose strut, time the extension with the new strut. That will give you a baseline
number so that you'll know when it's starting to get weak.

Subject: [LML] Gear Free Fall
I’d like to draw on the
opinion of listers regarding LNC2 gear free fall
problem.
The main gear is slow to free
fall, and on the jacks (most likely in the air) the RMG won’t lock
in.
Slight pressure on the wheel
locks it in, which is handy if one wing walks upside
down.
Disconnected the actuator
strut and it drops like a beauty and snaps into
position.
I doubt the actuator struts
are the problem because both main gear have exhibited the same problem at the
same time. The LMG does eventually lock down on the
jacks.
One thing I’ve noticed is the
NG is slower to lock down under normal extension than it usually does. Until
recently, it was always the first, and quick to lock down. Under free fall the
gas strut dives the NG down and locks as it should quite
quickly.
Wondered if anyone might have
a trouble shooting sequence I can draw upon.
Thanks
Dom
