Continuing on from the previous update:

The third and most startling admission by Gilmore is that he became aware in 1999 that the C.A.D.I. L160 wings were substandard, (This was as a result of a wing test done by the Dream Aircraft company for the Tundra wing development), however it would appear as though, as the then design owner, he failed to advise all of the earlier L160 owners of that C.A.D.I. model and did not post any AWB or SB about this on the BushCaddy web site, thus placing many owners at great risk.

Gilmore & Watkin have both made claims to me that the L164 wing loading had been tested, however it is now clear that they lied.
Full details of their statements along with further details of the assesments I have had done on my wing spars can be viewed on the Yahoo forum: fly_bushcaddy@yahoogroups.com

I have stated before that I do not belong to the 'Blind Faith' brigade, and believe that there are good grounds to be concerned and as a result I recently engaged another independant Aeronautical Engineer to view my wing structure and to give advice on my proposed method for re-inforcing the spars.
Increasing the Spar cap (flange) rather than the spar web is the best method to gain more spar strength, however this has proved too difficult with the current wing structure arrangment, so I settled on placing laminated plates to the inside of the spars.
