[Andrey Dikov]

My two cents. If the aircraft was unrepairable, then the loss was characterized by rather standard "Samolyot razbit, vosstanovlyeniyu ne podlezhit" = "Aircraft is crashed, a repair is impossible".

After that there should be a phrase characterizing whether it was combat or no combat loss: "Ot boyevich povrezhdeniy IA/ZA" ("Combat damage Fighters/Flaks"), "Ot drugikh prichin" ("Another causes") in case of non-combat loss, etc.

To sum up, I don't think that heavily damaged and written off crafts were sumed in non-combat columns of loss tables. And documents I worked with confirms my point of view.
