Final Report


On 21 January 2017, the crew of an Airbus A320 aircraft, registered VH-VNC (VNC), prepared to conduct Tigerair flight 491 from Cairns to Brisbane, Queensland. The flight crew consisted of a training captain and a first officer under supervision.

At about 1511 Eastern Standard Time (EST), the surface movement controller (SMC) cleared the flight crew of VNC to taxi to holding point B5, which was the clearance they had expected. The crew had briefed each other on that taxi route.

VNC then taxied behind another aircraft along taxiway B, but as that aircraft entered the runway from taxiway B4, the first officer of VNC inadvertently also taxied to holding point B4. At about 1515, the captain of VNC advised the aerodrome controller (ADC) that they were ready for take-off. The ADC cleared VNC to line up on the runway and, as the first officer taxied the aircraft onto the runway, the flight crew completed the pre-take-off checks.

About 1 minute later, the ADC cleared VNC for take-off. Immediately after the captain read back the take-off clearance, the controller advised the crew that they were lined up at the B4 (not B5) intersection. The controller cancelled the take-off clearance and subsequently cleared them to turn around and exit the runway using B4 and taxi to B5. The aircraft subsequently took off from the B5 intersection and the flight continued without incident.

There was a 403 m difference in available runway length, between the B4 and B5 taxiway intersections.

This incident highlights the importance of confirming that an aircraft is lined up for take-off at the correct intersection, or position on the runway, as well as the correct runway.
