A26 Progress----NOT!!!!!!!!!!!!!!!!!

Murphy cam to the hanger to visit us today. Somebody needs to find that SOB and execute him!!!!!!!!!!!!!!!! GOD ALMIGHTY!!!!!!!!!!!!!!


We WERE 2-3wks away from out first flight. We have worked out just about all the issues and gremlins.
Our right oil cooler has had a small leak and oil has deposited a small run down the outboard side of the right engine. We had decided to do the test flights and fix the leak this winter, no big deal. Well, the oil cooler leak has become worse and we decided to pull it out of the wing and fix the leak. We spent all day removing, disassembling the manifold and check valves, replacing the O-ring seals and put it back in the wing. The oil cooler is heavy, but one person can lift it, but when removing/replacing it overhead, lining up the oil lines, getting the bolts started, it is a major challenge and takes 4 people getting in each other's way. BUT, we finally got it back together and installed. We towed the plane outside and onto the ramp and fired up the right engine to make sure the leak was fixed. Well, DAMN, Murphy is still with us!!!!!!!!!. So we have to do it all over again, but this time we ordered fresh, new O-ring seals.


The first picture is the oil cooler removed and on the workbench.


The next 2 pictures are are the oil cooler bay in the right wing, just outboard of the right engine.


The next picture is the oil cooler manifold before it was removed.


The next picture is the faulty check valve where the leak was coming from.


The last 2 pictures are getting the cooler back into the wing and the cooler installed and all the lines connected (which are up high and cannot be seen easily------------much less easily reached to make connections and tighten clamps!!!!!!


This is going to set us back a little @#$&%#@! Oh well.

As much as I enjoy your posts I won't be liking this one. At least you got to spend time with your buds. I'm sure she'll be in the air soon.

Re: A26 Progress----NOT!!!!!!!!!!!!!!!!!

After reading about the latest difficulty in this great effort, I got to thinking about the maintenance guys keeping these things flying during WWII in the humid tropics. Heat, humidity, rain, rain, and more rain, bugs, malaria, working out in the open, etc.etc. The maintenance folks never seemed to get the credit they deserved. I did a little research and found a couple of references that I found interesting

Re: A26 Progress----NOT!!!!!!!!!!!!!!!!!

I was going to say, can you imagine the manpower to keep these babies in the air during war. Factories were cranking out as fast as they could, it was an amazing effort. Rosy the riveter. Maybe a set of small dexterous hands would be helpful.

Frustrating as this may be, things like this are bound to happen. Keep your eye on the big prize... it will all be worth it.
