The Australian Transport Safety Bureau did not conduct an
on-scene investigation of this occurrence. The report presented
below was prepared principally from information supplied to the
Bureau.
At 2020 Eastern Summer Time on 20 February 2005, a Boeing
Company 767-338ER aircraft, registered VH-OGO was being operated on
a scheduled passenger service between Sydney and Melbourne. The
copilot reported feeling unwell during cruise and was physically
ill during descent through FL 200. A flight attendant was called to
the flight deck to assist and the flight continued under the
control of the pilot in command with the copilot assuming a
monitoring role for the remainder of the flight.
After a 2-day recovery period, and having discussed his illness
with the company medical practitioner, the copilot was declared fit
and returned to duty.
