Jaco I have increased the centre section of the wing by 6" overall and shortened the outboard sections by the same amount. this is to accomodate a modified airbrake system to improve its short field performance. To gain approval from the PFA (UK inspection organisation) we had to use a modified WAF which consists of doubled 16 swg heat treated plates with ally bushes through the spar along the centre of the plates, also increased diameter main bolts. If you want a belt and braces job I can send you a copy of the drawings.
