[Signature] Torque Arm FB.2924. Failed after 19 1/2 hours running due to the front end insert pulling through the sheetmetal member; the fracture has occurred on the sharp radius forming the beading adjacent to the front face. This piece is now being cut up for investigation by Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie} Support Plate FB.2982 / N.S.5188 (Near Side).
