The oil level shall be checked for soak up to 60 degrees at ACPR by means of 0.5 litres of oil and the unwinding of the check-plug (that is squared) in "parking" mode by the engine running. About half a litre of oil should be forced out of ACPR.
The filler hole is closed by cork and is located under the control of the ACPR. We need to remove the airframe and disconnect the selector drive to fill the fresh oil at the ACPR.
