Summary
On 10 October 2016, an Airbus A319-111, registration CS-TTD, operated by TAP Portugal, was on approach to Santiago de Compostela Airport (Spain). The flight, with callsign TAP1710, had taken off from Madeira Airport (LPMA) en route to Porto Airport (LPPR). While on approach to Porto, the crew were instructed to enter a holding pattern over point RETMO because low-visibility procedures were in effect due to weather, which was causing delays. The crew had planned Vigo Airport (LEVX) as the first alternate and adjusted their fuel management based on that plan, monitoring the weather situation at Vigo.
Approach and Go-Around
During the approach to runway 17 at Porto, the crew informed both approach control and the Porto control tower of their intention to proceed to Vigo if they were forced to go around. Upon reaching the approach minimums, they could not establish the required visual reference, so they decided to go around and proceed to Vigo as planned.
Occupants and Damage
The aircraft carried 6 crew and 75 passengers, none of whom were injured. No damage to the aircraft was reported.
Investigation
The Civil Aviation Accident and Incident Investigation Commission (CIAIAC) investigated the incident. The probable cause of the incident is not stated in the available source.
