The New Zealand Transport Accident Investigation Commission (TAIC) published their findings regarding an incident in which an Airbus A340 commenced a night time takeoff at Auckand while misaligned with the runway.

On 18 May 2013 an Airbus A340 operated by LAN Airlines, Chile was making an early-morning departure (LA801) from Auckland Airport for a scheduled return flight to Sydney, Australia. In addition to the captain and the first officer, there were eight cabin crew and 196 passengers on board.

It was dark but the visibility was good. The captain taxied the aeroplane from the gate toward taxiway A1 for a take-off towards the west. As the aeroplane neared taxiway A1 the tower controller gave clearance for it to line up on the runway. As the aeroplane was entering the runway the tower controller gave clearance for it to take off.

The two pilots performed the remaining tasks and before-take-off checks while the aeroplane was taxiing. The captain then turned the aeroplane sharply to line up with what he thought were the runway centreline lights, but which were actually the right-hand runway edge lights, and applied take-off thrust.


While accelerating towards take-off speed, the captain realised that the aeroplane was not aligned with the runway centreline. He steered the aeroplane back onto the runway centreline and continued with the take-off. The pilots did not report the incident to air traffic control at the time.

A routine runway inspection later that morning found that seven of the elevated runway edge lights were damaged and required replacement. The runway was closed for 20 minutes while the debris was removed. When the aeroplane was inspected after it arrived in Sydney, two of the tyres were found to be damaged and had to be replaced.

TAIC found that at some point while the pilots were conducting last-minute checks and tasks before the take-off, the captain lost awareness of precisely where his aeroplane was in relation to the runway centreline.

The Commission also found that three other factors contributed to the misaligned take-off: the potential illusion created by the illuminated manoeuvre area guidance signs parallel to the runway; no other means were used to confirm positively the aeroplane’s position prior to take-off; and the rolling take-off which reduced the time available for either pilot to realise the error.

The Commission identified two broader safety issues relating to: the intensity settings for aerodrome lighting; and administrative errors and potential ambiguity in the way relevant International Civil Aviation Organization standards for airport design and operations might be interpreted. The Commission could not determine whether either of these safety issues contributed to the incident. Nevertheless, the Commission has made recommendations to the Director of Civil Aviation and the chief executive of Auckland International Airport Limited to address these safety issues.

Key lessons arising from this inquiry are:
– entering an active runway is a critical phase of flight. Pilots must give the manoeuvre their full attention and use all available means to confirm that they are lining up in the centre of the correct runway
– it is essential that pilots report as soon as practicable any suspicion that a runway is contaminated with debris.

The LATAM Airlines Group stated to ASN that the airline has addressed the recommendations in the TAIC report.
