Yr right Rob When u Iook at the stress directions on the U/C attachment points when landing and braking ... and the major reduction of the for and aft load capacity it is actually amazing it did remain intact for so long. However because the damage has been reflected by the low structural integrity of that area, the damage is confined. We have so far had a good response from Diamond which is refreshing. Hopefully some of WVW may fly again Best regards Ian W
