1988 NO. 158 CIVIL AVIATION REGULATIONS - REG 227

227. (1) A person shall not enter, and a member of the operating crew shall
not permit or suffer a person to enter, the crew compartment of an aircraft
during flight unless that person is a member of the operating crew of the
aircraft or is a person permitted by the pilot in command to enter that
compartment.

(2) A pilot seat or other operating crew position in an aircraft shall not be
occupied by any person other than a member of the operating crew who is duly
assigned for duty in the aircraft and is licensed for the duties associated
with that seat or position, or by a person authorised to enter the crew
compartment for the purpose of conducting examinations, inspections or checks
of the aircraft, its equipment, a member of the operating crew or the ground
organisation provided for use by aircraft.

(3) The pilot in command of an aircraft shall admit an authorised person to
the crew compartment and allow that person to occupy the seat or position
appropriate for the performance of his or her duties unless the pilot in
command is of opinion that the person's admission to the crew compartment or
occupation of that seat or position, as the case may be, would endanger the
safety of the aircraft.

(4) Whenever the pilot in command has refused to permit an authorised person
to enter the crew compartment or occupy the seat or position appropriate for
the performance of his or her duties, the pilot in command shall, if so
required by the authorised person, furnish a report in writing to the
Authority setting forth the reasons for his or her refusal.
