The SAE International EG-1A Balancing Committee is drafting new standards to modernize best practices for the design and use of tooling, fixtures, and accessories that mount and drive gas turbine engine rotors on horizontal and vertical balancing machines. At its recent working session, the committee drafted wording for the SAE ARP4163 standard that will establish new criteria for testing and validating balancing tooling so organizations in aerospace and other industries can balance rotors with greater ease and confidence. “The current industry standards for rotor balancing tooling were established long before the introduction of new-generation jet engines that feature lighter, faster spinning parts that must be balanced to significantly tighter tolerances,” said George Allen, Chairman of the SAE EG-1A Balancing Committee. “Since the new standards will have far-reaching impact on any company involved in balancing, we are actively seeking input from companies not currently participating in the EG-1A committee.” The EG-1A committee is comprised of representatives of several jet engine manufacturers, airlines, and maintenance repair and overhaul (MRO) companies. Representatives of companies interested in participating in developing the new SAE ARP4163 standard should contact or 802-253-2036, ext. 103.
