Operator Line Check
Subregulation 1
An AOC holder must establish and maintain an assessment (called in these Regulations an Operator Line Check) to assess a person’s competency in carrying out normal line operations, as specified in its Operations Manual, as a pilot for a flight of a large aeroplane before the person is assigned such duty.
Subregulation 2
The Operator Line Check established in accordance with paragraph (1) must include an assessment of a person’s competence as a pilot of an aeroplane of the type or variant that the person is to be assigned to operate —
in the relevant pre‑flight and post‑flight procedures; and
in the use of equipment provided on the aeroplane.
Subregulation 3
The Operator Line Check established in accordance with paragraph (1) must include an assessment of the person’s competency in both the duties of pilot‑flying and pilot‑monitoring if the AOC holder requires every person assigned to flight crew member duty as a pilot‑in‑command or a co‑pilot to carry out the duties of both roles.
Subregulation 4
An AOC holder must conduct the Operator Line Check as part of the normal flight crew complement for every person who may be assigned duty as a pilot for a flight of a large aeroplane.
Subregulation 5
Where a person has passed an AOC holder’s Operator Line Check, that pass (called in this regulation an OLC pass) —
is valid for a period of 12 calendar months, starting from the day the person passes the Operator Line Check; and
may be renewed for a further 12 calendar months, starting on the day immediately after the expiry of the existing OLC pass, if the person completes and passes an Operator Line Check that is conducted in the last 3 calendar months of the validity of the existing OLC pass.
Subregulation 6
Unless the person being assessed is the holder of a valid OLC pass, the Operator Line Check must be conducted —
in an approved flight simulation training device that is representative of the aeroplane type or variant to be operated by the person being assessed; or
in an aeroplane of the type or variant to be operated by the person being assessed, during flight in actual or simulated instrument flight conditions when the aeroplane is not carrying any passenger, cargo or mail.
Subregulation 7
For a person who holds a valid OLC pass, the AOC holder may conduct the Operator Line Check during flight when the aircraft is carrying a passenger, cargo or mail.
