(No. 8 of 1921.) Bristol " Tourer " and Bristol " Fighter " Aircraft :-"-• . Aileron Control Pulleys 1. The existing arrangement of aileron pulley guards onthe Bristol " Tourer " and Bristol " Fighter " type aircraft used for civil purposes is such that the aileron control andbalance cables tend to " jam " between the pulleys and their guards, and accidents on this type of aircraft have beenattributed to this cause. 2. Modified pulley guards, in accordance with Drawing• No. A.D. 3329, should be fitted to all civil aircraft of the above type at the earliest opportunity.The only new fittings required are the new pulley guard and shackle shown in the drawing, and, since the guard issplit, the new fittings can be assembled in position on the aircraft aver the existing cable, without it being necessaryto renew the latter. 3. It is also advisable that seven-strand cable should beused in preference to four-strand cable for these and other controls. 4.
