Landing gear problem (was "oh! crap")

[big al 08]

no groaning, must be stupid for i still do not undrstand why the hand pump would have almost total pressure bult up on it in tow or three pumps. flying north tomorrow will either take a shot on retraction or keep it a 336 until arriving at the maintenance shop in yuma, if i was sure the hand pump would work as it did today opening the doors up i wouldn't give a second shot. thanks rick
