Here's what we have done to get the overall system in shape: - removed the cleaned the main landing gear actuators for corrosion. The air system is gratifyingly tight at the moment. - Installed new chevron seals in the actuators - Cleaned shuttle valves and replaced rubber balls inside the valve - Removed mechanical uplock, cleaned, and lubricated Retraction is normal. We have been unable to reproduce this on jacks, and it's unpredictable in the air. The problem, when it occurs: the left MLG has normal extension. Nothing seems to happen on the right side (red lights go out). Then, after about 3 seconds, the gear slams down so hard that it "bounces" into the lock position (the green light blinks momentarily). Any thoughts on what is happening here or how to better diagnose? We did 6 cycles on jacks with perfect (simultaneous) extension before giving up.
