Airframe event involving a Boeing 747-200, HS-TGS, Brisbane Aerodrome, Queensland, on 21 September 1996

When the aircraft arrived in Brisbane, ground engineers noticed that the left number 11 leading edge flap was missing, and that there was slight damage to the number two engine core cowl. No evidence was found to indicate the primary failure point. A new flap was fitted, and the aircraft was dispatched the next day.
