Anyone seen final report?
 

According to aTurkish news site Sabiha Gökçen'deki uçak kazasına ilişkin kaza kırım raporu tamamlandı - Son Dakika Haberleri (trthaber.com) March 17th 2022 the final report has been released. (This page is in Turkish but Google translate works tolerably well) However I can't find any refernce to a version in English - anyone seen it?

As far as I know Turkey generally does not publish reports, and certainly not in english. At least I have not found them. Sometimes you find fragments of reports ...

The UEIM does publish reports reasonably often (half a dozen so far this year), but typically only those for GA accidents are considered to be in the public domain. The most recent report on their website is for a December 2021 event.
