Referring to Roy{Sir Henry Royce}/Msl/P9.9.30. Now that we have standardised head lamps off the frame instead of off the front wing stay, it might be that we can use up the existing stock of present design of wing stay. We think you will agree that taking the head lamp off the wing stay will reduce the risk of failure very considerably. Actually there is no standardisation sheet for the modified wing stay, the reason being that we have not yet seen one of these. Hs.{Lord Ernest Hives - Chair} | ||
