A Pobeda Boeing 737-800, registration VQ-BTH performing flight DP-837 from Moscow Vnukovo (Russia) to Istanbul (Turkey), was on final approach to Istanbul's runway 23 when the crew decided to go around from low height but did not turn left immediately as instructed by the missed approach procedure and continued straight ahead.

A Pegasus Boeing 737-800 registration TC-IZE performing flight PC-3303 from Istanbul to Izmir (Turkey), departed Istanbul's runway 17R and was in the initial climb through about 700 feet AGL when the Pobeda 737 crossed their flight path twice turning onto the missed approach.

The Pegasus Boeing stopped the climb at about 1000 feet thus remaining below the Pobeda.

After being clear of conflict the Pobeda joined the correct missed approach procedure, positioned for another approach and landed safely on runway 23 about 21 minutes later. The Pegasus continued the climb and landed safely in Izmir.

Turkey's Civil Aviation Authority reported the separation between the two aircraft reduced to 700 feet vertical with about 250 meters/0.13nm horizontal separation. An investigation has been opened into the occurrence rated a serious incident.
