A happy July 4th to all my American friends!

Firstly this is a thank you to Tim Ong and Mark Mahnke of Lancair for =
the speed with which they dealt with my problem yesterday.  It took them =
less than an hour.  Let's hear it for these two and the company that is =
smart enough to have them working there.

This is also a heads up to anyone who is putting the wings on for the =
last(?) time.  In brief I put on the right wing, no problem.  I ran the =
bolts up with a 1/2" drive ratchet, set my torque wrench to 40ft/lb. =
(Yes it is calibrated) and bingo there it was.

The left wing was no problem on the outboard bolt but whilst I could run =
the inboard bolt hard up with the ratchet the torque wrench indicated =
that the setting was below 40ft/lb and it would not reach the 40ft/lb =
however hard I tried.  I quickly deduced I had a problem and then the =
bolt stripped and was removed.  On examination it appeared as if the =
bolt had too long an unthreaded shank and had reached the end of the =
thread before reaching the torque required.  Put another way the grip =
length of the bolt was too long.  I had a washer under the head and the =
bolt is the bolt that came with the kit.  The repair procedure is no =
gift but I am not bitching as I had envisioned a dreadful tragedy and =
all I got was some inconvenience and a day's extra work.

My advice is that before you assemble the the wings to the centre spar, =
very carefully measure the parts that fit together and accurately =
determine the grip length required.  Compare this to the bolts you have. =
 It is permissible to use up to two flat washers under the bolt head. If =
this does not do the trick get the next shortest grip length.  Do use a =
torque wrench.  In my case I know that I cannot pull 40ft/lb in the =
space available.  If I had not used a torque wrench and had just used =
the 1/2" ratchet I would have flying with not only a slack bolt but a =
stripped one.  Makes you think doesn't it?

I will be pleased to pass on the repair procedure to anyone who needs =
it.  Misery loves company.

Regards

Ian Crowe
