Just a word of caution; do not over use the hand pump. It can actually increase the pressure that the system normally sees and it is made to use in emergencies only. Like any componant in the aircraft it has a life cycle. I don't think you want to shorten the life of that pericular componant.

I want to thank everyone for the help. The mechanic worked on it some more and found that the hydraulic hoses were routed in a way that caused the problem. A slight adjustment to the location of the hose routing seems to have corrected the problem.

The routing of the hoses is the problem. You want the hoses positioned so down locks are held in the up position until the gear strikes them and causes them to start to swing. At that time the movement opens a valve and causes them to pressurize and lock down.
If the locks start to pressurize too early you will have problems. Good luck. |
