I have had both engine driven hydraulic pumps overhauled. In 35 hours the right pump start to pour the Skydrol (yes Skydrol) overboard through the bypass drain hose. When I called "Thunderbird" (who overhauled it) they told me that I did not have a pump problem but a "check valve" or "pressure relief valve" or "accumulator" problem, (anything but a pump problem). He said that if the check valve (or any of the above items) are not working correctly it will let pressure get onto the suction side of the system and will roll an internal seal in the pump it'self. Has anyone got information that could enlighten me instead of my engineers making my wallet lighter? Second item: When this aircraft was delivered to me there was no hydraulic filter (or assembly) in the hydraulic resevoir. I have already purchased a used filter for a large fortune but need 6 more parts to complete the installation. The 6 parts I need to find are as follows; Qty. 1 - Plate - Part number 2790168-3 Qty. 3 - Gasket - Part number 5790162-7 Qty. 1 - Welded assembly - Part number 5790162-16 Qty. 1 - Nut, shank (73168) - Part number 92NL22-02 Qty. 1 - Washer - Part number AN970-4 Qty. 1 - Gasket - Part number 2790168-5 Does anyone have a source for any of the above items, please?

After four failures and changing one hose, one pump then both pumps, then all hoses and both pumps we changed the accumulator and that solved the problem until one of the new hoses failed.

I need to do a dry run so I have something to say to everyone at the briefing before the poker run on saturday. I was thinking of a Noon departure or so, so we'd be back in plenty of time to see the "golden pedal" landing competition. You can reach me anytime at 650-938-9500.
