Gear problem

[Skymaster337B]

I've been having the same problem, gear goes up, no amber light, gear doors stay open in the air. But everything works ok when jacked up in the hangar. I put new switches on the up locks and power pack, checked tire pressure, checked fluid levels, and serviced nose gear strut; but still nothing worked.

I finally put new springs on the main gear uplock pushrods, and I'm happy to report all is good. However, good luck finding a new spring. It seems Cessna doesn't make them anymore, and I got the last one in the system.

There's plenty of used springs available, but good luck using them since you already have a used one installed. The new spring was a full 1.5" longer than the old worn out one.

Enjoy,

Rob
