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

The new spring is longer? Does that make sense, wouldn't the old one be weak and stretched?

The old spring is shorter because it was under constant compression for the last 40 years.
