| Hs.{Lord Ernest Hives - Chair} from GWH.{George W. Hancock - Head Chateauroux} C. to RHC.{R. H. Coverley - Production Engineer} C. to Rm.{William Robotham - Chief Engineer} C. to Hy.{Tom Haldenby - Plant Engineer} X1113 COMPLAINTS. HAND LEVER FOR RIDE CONTROL. GWHB/GR.{George Ratcliffe}5.11.36. We have run into trouble with the small flat spring F.80485 for the hand control lever breaking. The failures are occurring on the latest 30 H.P. This spring has been in use on all the 25 H.P., and until recently given very little trouble. The present cause of failure would appear to be due to over-hardening. G.W. Hancock. | ||
