I have in front of me a CASA approved flight manual for a widely used twin and I quote,
"Experience has shown that the training advantage gained by pulling a mixture control or turning off the fuel to simulate engine failure at low altitude is not worth the risk assumed. Therefore, it is recommended that instead of using either of these procedures to simulate loss of power at low altitude, the throttle be retarded slowly to idle position. Fast reduction of power may be harmful to the engine."
A certain CAR,
Pilot to comply with requirements, etc of aircraft’s flight manual, etc
(1) If a flight manual has been issued for an Australian aircraft, the pilot in command of the aircraft must comply with a requirement, instruction, procedure or limitation concerning the operation of the aircraft that is set out in the manual.
Penalty: 50 penalty units.
Does CASA regard a flight manual recommendation not to be a CAR requirement, instruction, procedure or limitation?
