Preliminary report has been published (in Polish only, but with many pictures):
http://www.mir.gov.pl/Transport/Tran...14_0982_RW.pdf
Findings:
- APP offered visual approach which was accepted by the crew
- existing runway, approach and PAPI lights were turned on at 100%
- ATIS did not contain information about rwy in construction
- markings on the rwy were not sufficient
- observation from TWR is difficult due thresholds displacement
- visibility was limited due rainshowers
- EGPWS had no "Smart landing" feature installed and its map resolution was too low to detect the mistake
