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 total clear of any 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.

There is a lot of equipment to set up and warm up.

|
|
The milliRad meter to make sure we were safe.

The equipment was set up plenty far from the plane.

The AD requires the wings to be uploaded at wing station 10.

There is a specific weight that is required.
