| H.{Arthur M. Hanbury - Head Complaints} from Rg.{Mr Rowledge} c. to E.P. c. to E.O. RECEIVED X3/91 RE 8-EAGLE ALTITUDE CONTROLS. Reference EP{G. Eric Platford - Chief Quality Engineer}/P5/F16821. Rg{Mr Rowledge}10/W17. 8. 21. X3191 X3134 For commercial machines, particularly those running on the Paris Service, I want to be able to use a fixed jet in place of the Altitude Control, to get over the trouble due to wear in the control parts. These machines do not use the Altitude Control. Will you please make tests and let me have the size of jet required. Rg.{Mr Rowledge} | ||
