Capt D,

I'm in agreement about not adding the centering cams to my nose strut.
There were actually several (rougly 4) struts for the LNC2 with all
their own uniquenesses and AD's.  In particular, adding the centering
feature was not an AD to my knowledge.  Also, the non-centered issue was
mute if the aft nosegear door attach #8 Screws were cut off short per
the plans.  The centering feature keeps the little arc scratch off the
nosegear door.  I am not aware that there is concern of gear hangup
based on this issue.

One safety AD that I'm thinking of has to do with the collar at the base
of the strut.  My attach point uses a big roll pin.  The newer modified
attach points use a collar.  The concern was regarding the roll pin
wearing, then shearing, and subsequently potentially loosing the lower
horseshoe bracket and wheel in flight.  This roll pin I inspect on every
preflight.

Also, the other AD had to do with internal turn radius limits.  It was
about jamming the strut to beyond 25 deg (I believer) with a tow bar and
damaging the internal stops.  Lancair sent out a little sticker to
remind us to keep the turn radius less than 25 degrees.  Mechanical
towing (tight radius backing in particular) could be a big threat in
this department.  Since this is not inspectable externally, I am very
conscientous as to who and how my plane is towed (normally me and
carefully!).

Finally, the very early struts had some AD's that unfortunately lead to
Dr Fopp's damaging his plane.  I don't remember the specifics but most
of us do not have that strut.  I believe it was the first oleo strut
after rubber donuts were removed from the 235's.

Hope that wasn't more than anyone wanted to hear.
