| public. To RHC.{R. H. Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} 25-EX. will you please arrange to fit Torque Reaction Dampers to 25-EX, so that the fan is still in use. The dampers are needed to hold the engine torsionally rigid in the frame and thus it is important that they are not flexible. Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} | ||
