RHC.{R. H. Coverley - Production Engineer} Rm.{William Robotham - Chief Engineer} c. Hs.{Lord Ernest Hives - Chair} 337. BY.9/N.6.4.38. Re: Phantom III - Propeller Shafts. Referring to your memo RHC.{R. H. Coverley - Production Engineer}1/MC.4.4.38, pointing out the failure of the propeller shaft was due to faulty sweating, and not a question of design, I agree to retaining the same number of pins, but increasing the diameter from .250 to .312 and we are issuing an alteration covering this.
