On 18 January 2019, two aircraft taxiing for departure at Helsinki were cleared to cross the landing runway between two landing aircraft. Landing clearance for the second was given once the crossing traffic had cleared as it passed 400 feet in expectation that the previous landing aircraft would also shortly be clear. However, the first landing aircraft was slower than expected clearing the runway and so the second was instructed to go-around but did not then do so because this instruction was lost in the radar height countdown below 50 feet and the runway was seen clear before touchdown.
Description
On 18 January 2019, a Boeing 737-900 (TC-JYH) being operated by Turkish Airlines on an international passenger flight from Istanbul to Helsinki as THY1XE was slow to clear the landing runway at Helsinki after completing a landing in night VMC and the next landing aircraft, a Boeing 737-MAX 8 being operated by Norwegian Air International on an international passenger flight from Krakow to Helsinki as IBK351, was instructed to go around when on very short final but did not do so after the crew had confirmed that the runway was completely clear.
Investigation
After a Serious Incident was notified by ATC, an Investigation was carried out by the Safety Investigation Authority of Finland (SIAF) into the circumstances which had led to the issue of the very late go around instruction and the landing which was then completed contrary to it. ATC radar and voice recordings were available and FDR and CVR data relevant to the event were provided by Norwegian Air.
