Just an update on the testing procedure and results on the TP wing
tested at Kitchener Waterloo International Airport last year.

The wing was instrumented with strain guages. The main spar was
bending significantly between the Cabane mounting and the strut, and
the strain readings were beyond the limits the engineer was
comfortable with at 2Gs testing for a 600 lb plane.Failure was
IMMINENT.

I don't understand why the testing did not continue. Seems to me that
having someone say that failure was imminent, based on strain gauges,
leaves a lot of room for opinion to creep in.
They didn't want to have to shovel up the sand when the sandbags
split on the floor.


I don't have much interest on either side of this but have been reading with
curiosity. This last statement was really very lame! If someone's purpose
was to prove a design was deficient you would have thought they have tested
to failure. I doesn't cost alot to get a couple high school kids to do the
shoveling.
My question, How much permanent deflection in the wings after the test?
