REFLECTOR: Odd Jorgensen and center spar section lay-ups

[Alex Balic]

Well I remember those layups well- I remember how difficult it was to get
the job done through the hole at the rear of the spar- but they are critical
layups- the CS spar has relatively low torsional strength, and without the
solid bracing of the strakes, at least excessive flexing, and at worst
failure is bound to occur.  If the connecting layups are not properly
attached- I had the old paintbrush on a stick going for almost an hour in
there to make sure it was all solidly down and at least as good as the other
layups on the spar- although the manual does note about this- I would
recommend that perhaps it should be highlighted more that these are CRITICAL
structural layups.   As for the report from James- I remember reading this
when it first came out- I commend him for writing it, and feel for the loss
of his father- however, his father's continued lack of regard for bad
weather is what directly lead to his death- I have met several such pilots
in my time - hopefully some of them are still alive.

A few had asked about the lay-ups on Odd's plane.  I had not seen a reply on
the reflector.  They may have been responded to directly.

I had remembered reading a report by Odd's son James.  The report had
mentioned glass work.

I was able to locate the report.

It does reference glass work:

"Duane Swing inspected the wings and expressed some concern about the 
appearance of the region connecting the torsional lay-ups of the 
strake to the center section spar."

I placed a copy of the report here:

I'm not sure exactly which specific lay-ups Duane is referring to.

My feeling is the lay-ups inside the "hell hole" that bond the inner skins
of the strake to the center spar section.
