(2) We are proposing to circulate a Depot Sheet with reference to those series of Bentleys where the fan balance may not have been accurately checked. It is not sufficient to check the fan in position as there may be sufficient grease in the hub to mask out of balance. (3) By.{R.W. Bailey - Chief Engineer} is instructing improved material for the fan spindle, and also making a modification to improve the rivetting of the blades. HE/Rm.{William Robotham - Chief Engineer} | ||
