Fairey-Reed Airscrews : Periodical Examina tion for Defects. (60361 30.) Instances have occurred of transverse fatigue failure of the blade sheet of Fairey-Reed airscrews fitted with metal hub blocks, the fract ures commencing at the holes for the hub bolts or the tubular bolts securing the metal blocks, and extending towards the leading and trailing edges. An instance has also occurred of transverse fatigue failure commencing from the identification stamping. As the result of these failures, it is necessary that, in future, frequent inspection of these airscrews in the vicinity of the hub blocks and identification stamping be made. The blade sheet must be carefully examined on both sides in the above- mentioned regions. Where metal hub blocks are fitted, both sides of the blade sheet visible through the lightening holes must also be examined. For this purpose, airscrews must be removed from their hubs, and spinners, where fitted, removed from the airscrews. In no circumstances, however, may the hub blocks be removed from the airscrew. Airscrews on which any signs of fracture are observed, must be removed from the aircraft and the matter reported. January 23, 1932. AIR MINISTRY NOTICES TO AIRMEN. SKRIK.s A No. 71 of the year 1931.
