Larry,

I am in China right now and don't have my LNC2 manual handy, so this is
from memory.  If I mis-state anything I am sure my fellow list member will
correct me.

Maybe you are in the same situation as I was.   I bought an unfinished
LNC 360 kit originally sold in 1991.  In the manual that came with it
there is NO MENTION of safety wiring the spar bolts!!  I contacted
lancair and they sent me
a manual update that showed the correct way.  

Actually, the change was more significant than just the safety wiring.
 The new manual shows two added flat head bolts that tie the metal
plates in the spar to the kevlar spar material.  These are needed to
distribute the bolt load to the
spar itself. Without them, under high G loads, the spar might just slpit down
its length like a piece of pine.  And that would ruin your whole day.

The added bolts also provide the place to tie the safety wire to.

Adding the bolts is not too hard, but you will need a right angle drill head and
a short drill bit.  

Soooo, if you have an old LNC2 and you cant find a place to wire the
spar bolt heads, your plane may need a bit more work than you thought.

Contact lancair for the manual update.

Cheers,

Jeff   N273CK, still building.
