 |
|
After wrestling with the perceived problem for awhile, and trying installing the spacers that come with the slow build kit (which did help with alignment) I decided to wait until I actually got the wing spar inserted in the center section.
Surprise...the right wing holes lined up about as well as can be inspected.
Somehow having th spar inserted seemed to fix any misalignment.
When I got to the left wing, the top 3/8" holes were very tight on the alignment pins, so I investigated. I found that it was the wing spar where the problem existed, not the center section. The spar web did not did not line up exactly with the main bar spar cap. Talked to Van's. They told me to not use my 3/8" undersize reamer from the bar side because it would remove metal where you do not want to change clearance. Their advice was to work from the web side with a Dremel with abrasive bit(with dowel or bolt in the bar to prevent going too deep) until the interference was solved, then prime the area worked on.
I did that. Problem solved. As insurance, I stored the bolts under dry ice overnight before installing. They all went in okay, some needing firmer tapping with dead blow mallet than others. Van's did say that the web misalignment they had heard of a few other cases before mine.

I will check, but the wing # vs fuselage # is irrelevant in this case. It is the two halves of the center section on one side of the fuselage that have the misalignment. At this stage the wings are not involved. Unfortunately my QB was one of the first to come out of Manila after relocation/reorganization of the facility their. There were a number of QC issues right from the start, like not countersinking the longerons before riveting on the dimpled skins.

Hi Kelly,
After commiserating with you in reading your email, a thought occurred to me. I had purposely forgotten about this so as not to have continuous bad dreams about it. So here is the question: Do you have the same serial number fuselage as you do wings? As in, are the numbers matching? As in, were you one of the unfortunate ones that lost your quick build in the Philippines weather disaster some years ago???
