ROTAX OWNERS CAUTIONED ABOUT USING IMPROPER COOLANT The FAA has issued a special airworthiness information bulletin (SAIB) to alert owners and operators of Bombardier-Rotax 912 A, 912 F, 912 S, and 914 F series engines about using the proper type of coolant. Using the improper type of coolant can result in a loss of coolant and overheating when the engine is operated at cylinder head temperatures above 120 C, said the FAA. The affected engines are installed on certificated airplanes like the Diamond DA-20 and on many experimental and light sport airplanes.
