CS-E 190 Engines for Aerobatic Use

Where approval is sought for an Engine intended for use in an aeroplane for which the Flight Manual will approve aerobatics or semi-aerobatic flight, the ability of the Engine to continue to function safely in conditions of inverted flight or for intentional negative g conditions for specified periods must be demonstrated. Where the evidence is considered to be acceptable, and such tests as are necessary have been completed satisfactorily, the Engine Type certificate data sheet will be endorsed by means of a note, e.g. ‘the Engine may be used under sustained negative g or inverted flight conditions for continuous periods not exceeding... seconds’.
