These are the pictures taken of the spar x-ray process conducted on February 5th, 2008. The process used was conducted by Dr. Klay Roberts of Atomic Inspection Labs. He used the very latest in digital x-ray technology and informed me that the detail generated would far exceed the requirements of the FAA Airworthiness Directive (AD). The results were excellent, the spar is almost completely clear of corrosion and there are no cracks. Oddly one of the original factory welds has poor penetration and must be repaired. We now know for sure that we have a good airplane. The pictures at the bottom show a few of the x-rays. These do not have the same level of detail as the actual x-rays but they do show the total lack of corrosion, and the amazing detail generated by the digital process. Because we had such good access to the spar we were also able to shot from more advantageous angles than normal.
The main control box
First shot ready to go on Station 12 to 20.
The equipment was set up plenty far from the plane.
The AD requires the wings to be uploaded at wing station 10.
The milliRad meter to make sure we were safe.
We used what we could to get the correct angles for the various shots
Each film had to be identified for location.
Note the fine tuning duct tape.
There is a specific weight that is required.
The sensor equipment and box of lead letters and numbers
There is a lot of equipment to set up and warm up.

This shot is actually part of the proposed spar AD modification and looks like new
The very complex landing gear cluster
This is the shot that showed the bad factory weld
