There are no e= xternal leaks.

There are no other functional problems with the landi= ng gear system.

Since the gear down is the low pressure side=2C it s= eems unlikely that if there was a low to high leak in a cylinder=2C that th= ere wouldn't also be a high to low leak with the gear up.

My gut fee= ling is that it's an internal cylinder leaks (low to high)=2C but it doesn'= t make perfect sense.

Could a faulty pressure switch on the pump cau= se a problem like this?

What else could cause it?

Anyone have= a identical problem?

Thanks in advance -- Bill Kennedy
