Rutan:
Its broken in different places each time. The forward attach fittings have broken, so have the rear. We do now have the doubler mod fitted. It also needed the rear 2 or 3 (cant remember how many) bulkheads replaced as they cracked. Was a rather expensive process. I would say part of the cause of the bulkhead damage would be directly related to the stinger on the tail.
