Tracy et al -
  Actually, this is going to be a DIFFICULT SB for any LNC 2
builder or owner, except possibly for those in the early stages of
construction who have not yet installed their stub wings. The reason Lancair
chose a "brace" instead of a full-width replacement of the secondary attach
point (spanning the upper and lower spar caps... a superior design) was to
reduce the amount of rework. Bracing the attach point (vs.installing a new
one) still requires removing each main gear (which requires removing the
wings) in order to have full access to the attach point for prepping,
installation of lay-ups, etc. That's less work than having to break out the
existing attach point, which is really a difficult job. This will be a
fairly critical rework, so a lot of care should be taken to get it right.
