| To E.{Mr Elliott - Chief Engineer} 314 Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}17/JH.7.5.37. Phantom III Connecting Rods. Two of the forked connecting rods taken out of 34-EX chassis after completing the journey across Africa have broken at the bolts recess. These are failures similar to the ones that occurred before the blade rods were strengthened up at this point. Will you please instruct for a design modification strenthening the forked rods at the bolt recesses. The above rods are available for inspection.
