I cut and fit the pilot side forward seat pan (F-640, the sheet the control stick comes out of) and I'm concerned since things are not "looking" right. I followed the dimensions on the plans but that doesn't always mean it's correct.
This first picture shows the control column attachment to the spar bulkhead. On page 37 of the plans it shows a "Rev 3" that notes a "reverse flange on F-633" which is the control column mount. Below is a picture of that area. As you can see, the control stick is not centered between the ribs. If the control column mount (F-633) was swapped with the other side it would center the stick between the ribs.
Next is the fwd seat pan on the left side. Although I cut the sheet as shown on the plans you can see the rib on the left side is exposed as is the flange on the spar bulkhead. It doesn't show on my plans, but is this portion of the spar bulkhead flange suppose to be removed to get full forward stick movement?
Logic tells me that the cut out for the stick opening should line up with the seat rib flange on the left and right side and also with the spar bulkhead flange. I think I cut the opening correctly since the control stick is in the center. I'm hoping I didn't make a mistake when positioning the seat floor ribs but I haven't gone back and measured those yet.
I sure would appreciate any thoughts the group might have regarding this operation.
and another view.
