CHASSIS. X4260 X4268 We have broken the frame at the dumb iron in identically the same place as the previous fracture. This frame only lasted 7 hours. We were running with excessive clearance in the bushes on the springs. We are now waiting for the new dumb iron before we can carry out any more bump tests on the front of the Goshawk chassis.
