Rotax announces TBO extension for 912 series engines
The time between overhauls (TBO) for new Rotax 912 series engines has been extended from 1,500 hours or 12 years to 2,000 hours or 15 years, Rotax announced Dec. 14. New 912, 912UL, 912S, and 912ULS engines already carry the extended TBO, Rotax said. Older engines can have their TBO increased by complying with the provisions of Service Bulletin SB-912-057UL. The service bulletin calls for replacing a crankcase part and a plug screw, plus an associated test run. See the Web site for more information.
