Hi
I do have an RV6 so i dare to post about another aircraft type.... I have a Glasair 3 with a problem I am trying to solve. It's with the landing gear.
On the extend side the pressure in the hydraulic system drops very quickly. it extends the gear, pressure is then just under1000 PSI as it should be, but almost immidiately the pressure drops and the pump therefore kicks in again, then the pressure reaches the 1000 psi, pressure drops again and pump kicks in, this happens every 2 seconds. It seems like I might have a leak, but that is not the case as there are no leaks anywhere, could this be air in the system that causes this? Pump works ok and if retracting the gear, the pressure remains steady, its only on the extend side this happens.
I have a manual override that can turn the pump on, it will pump the extend side to 1300 psi, it drops with about 100 PSI/second. Any ideas?
