Incident Overview
On 13 May 2018 at 06:50 UTC, a Boeing 737-800 (type not further specified in the source) was conducting an approach to Fuerteventura Airport (GCFV). The crew had received clearance for the TERTO6S arrival to runway 01 and had briefed the approach. However, during descent, the flight crew erroneously selected the ILS 01 approach with the TENDA transition in the Flight Management Computer (FMC).
Sequence of Events
Following the incorrect selection, the aircraft flew the ILS Z 01 procedure (radial 189 from LTE to 36.1 NM from LTE, then a 12 NM arc to intercept the localizer) instead of the intended TERTO6S procedure (waypoints TOSPU, NIDOM, FV621, FV622, FV623, SOTAD). After passing the TENDA point, the controller twice instructed the crew to fly the TERTO6S. The crew erroneously confirmed compliance. The controller then interrupted the procedure, instructing the crew to fly heading 190 and providing radar vectors to intercept the localizer for runway 01. The landing was completed without further issues. The crew later telephoned air traffic control to explain their mistake.
Weather and Other Factors
Weather conditions were reported to have no influence on the event.
Probable Cause
The official investigation determined the cause as human error: erroneous selection of the STAR procedure for the destination airport.
Outcome
The investigation was conducted by the operator. No safety recommendations were issued. No preventive actions were taken by the operator.
