There is a bar on each side of the cylinder in that picture and shown on the drawing on page 43, but these bars do not appear in the Luke Field picture on page 43.
Were the bars a design update on AE’s plane when they repaired it? Or are the bars missing in the Luke Field picture?
I don't know what bars you're referring to.
There are two rectangular profile bars on each side of oleo cylinder, close to the top, in the picture you posted
I don't know the name of that part to describe it correctly but the installation illustrated on page 43 and the parts in the “gear parts-1052” picture do not look like the part in the Luke Filed accident.
This Luke Field part has a round profile, possibly a round tube, and seems to be off center of the cylinder, not on both sides.
The part in the installation drawing on page 43 and as seen in the photo you posted have a flat rectangular profile bar on each side of the cylinder and they are continuous, they bend around the cylinder so they can be continuous.
It seems like AE’s plane at the Luke Field crash had a different installation than shown on page 43.
At the bottom of the pdf I posted it had two images side by side where you can see the difference in parts
Page 43 has the Luke Field Image and the installation 40650 drawing above it so the difference can be seen there too.
