Your translation is good, I can understand what occurred. I appreciate your efforts in providing this information. The termination of the accident cause is likely “Settling with Power” or just being caught in a down-wash.

As always one question answered generates ten more. So! Do you have the Bort number and the Unit designation for the crashed Hind. What happened to the rest of the crew? How can I communicate directly with any of the crew members? Any other photos of the crashed Hind? The other incident mentioned “remembering similar crash some time ago” – what was the date of that event?

you are really a demanding man:-)))info of the kind what I have wrote here are very dificult to recontruct from various sources, so I cannot answer as a factory of mass production. The hind was of 4012 number anf of 11. vrtulníkový letecký pluk/helicopter regiment from Plzeň-Bory AB (the second helicopter base of CSAF was in Moravian part of Czechoslovakia on Prostějov AB, long distance from “imperialistic” border). Only pilot had to be pensioned, gunner and technician got healthy. No, I don´t know how to connect these men, and I guess they wouldn´t talk about these stuffs. Sorry I haven´t no more photos, the incidents as this was strictly secret and commies chief of army restricted all info, photos etc. The photos above are very rare and from vrtulnik.cz web. I don´t know what means “remembering similar crash some time ago”, just translate from a source… (just info, that during “the previous” crash two technicians have died in fire so the technician´s action to open boardside door before crash), interesting stuff is, that the the same Hind 4012 had some technical problems during a flight 8.7. 1982 but as helicopter of the second helicopter unit – 51. vrtulníkový pluk near Prostějov, but probably without crash (no more info I cannnot get)

edit: I have found the source about “the previous” crash – 17.5. 1983 of Mi-24D 0148, pilot, gunner and two technicians were killed…. info later as well as abou Mi-4 and F-102 incident… now just photo
