Gear Retraction Issue

[pilotpat]

We had a similar issue (ours does not have the gear door mod). It turned out to be the pressure switch (basically a plunger pushed by the hydraulic fluid to actuate a microswitch). The fluid sealing o-ring had swelled enough over time to cause the plunger to stick, so when the system pressure fell the pump would not run, and the gear only partially moved. It was an intermittent failure that took quite some time to reveal itself. Good luck!
