If it is, suggest copying and laminating and placing in front of AFM.
Further to this and from the explanation section-
This exemption, therefore, exempts the operators of single and multi-engine piston engine aircraft not above 5700 kg maximum take-off weight and not involved in Regular Public Transport (RPT) operations, aircraft engaged in agricultural operations or private operations, single turbine engine helicopters certificated in the normal category and not involved in RPT operations or single turbine engine helicopters certificated in the restricted category not above 5700 kg maximum take-off weight or hot air balloons from the requirement to have the flight check system separately approved.
It also exempts all persons associated with the operation of the aircraft from the requirement, under subregulation 232 (5), not to fly the aircraft unless the flight check system has been approved.
As a condition on the exemption, an exempted operator will be required to describe the flight check system and publish it in the operator’s operations manual in accordance with regulation 215 or the aircraft’s flight manual.
