Subject: Re: Gear Trouble

Bob,

Good question! The only thing that I can think of is that the valve  
that opens on the low pressure side when the gear lever is put into  
the up position, doesn't stay open.

I have plenty of experience to know that the low pressure side  
somehow builds up pressure when I fly high but I don't know why.

Opening the dump valve absolutely reliefs the pressure in the low side.
