Subject: [LML] Gear Free = Fall

I=92d like to = draw on the=20 opinion of listers regarding LNC2 gear free fall=20 problem.

The main gear is = slow to free=20 fall, and on the jacks (most likely in the air) the RMG won=92t lock=20 in.

Slight pressure = on the wheel=20 locks it in, which is handy if one wing walks upside=20 down.

Disconnected the = actuator=20 strut and it drops like a beauty and snaps into=20 position.

I doubt the = actuator struts=20 are the problem because both main gear have exhibited the same problem = at the=20 same time. The LMG does eventually lock down on the=20 jacks.

One thing I=92ve = noticed is the=20 NG is slower to lock down under normal extension than it usually does. = Until=20 recently, it was always the first, and quick to lock down. Under free = fall the=20 gas strut dives the NG down and locks as it should quite=20 quickly.
