My L-360 is not flying yet, but my = gear=20 hydraulic system has been done for just about a year and tested often = with no=20 problem, after I reversed my valve. My pressure is holding good for up = to 6=20 to 8 hours with gears either up or down, tests in a=20 garage.

At gear down selection, gears go = down,=20 pressure is at 550psi....after 8 hours, pressure is at = 470psi
At gear up selection gears go up, = pressure=20 is at 1,150psi.... after 8 hours, pressure is at = 890psi

Could some one help me with this=20 question:

My pump does not chirp (and=20 re-pressurized) until pressure goes down to 450psi; and this is truth = for both=20 when up or down is selected. When I have down gears selected, 450psi = chirp=20 action is great, but if up is selected, I would like to see chirp = action at=20 higher psi, perhaps 950psi.

I feel fortunate.

After reading several posts on the thread of the gear pump = burping,=20 chirping, cycling, running, leaking, not operating (Lorn's picture = made me=20 wince a bit), from other LNC2 pilots, I can report, that my=20 hydraulic gear system operates problem free with no burps,=20 chirps, cycling, or leaks, while in flight. Am I in = the=20 minority?

I hope I haven't jinxed myself sending this post.
