At 18:39 hours the co-pilot contacted Surat Thani aerodrome controller and reported over the Intermediate Fix (IF). The controller informed him that the precision approach path indicators (PAPI) on the right side of runway 22 were unserviceable while the left lights were in use.
At 18:41 hours, the co-pilot reported passing final approach fix (FAF). The controller informed the pilot that the aircraft was not in sight but it was cleared to land on runway 22. The surface wind was blowing from 310 degrees at a velocity of 5 knots so the pilots should be careful or the slippery runway.
