I only have data for 1941 on hand, but there were 327 Luftwaffe planes written off as operational losses on the eastern front.
Will leave the page I took a photo of as a link instead of embedding it, it's too big. https://i.imgur.com/yzsTREw.jpg
Not that clear it was 327.
It's not clear how losses for unknown reasons were categorized and it seems that only incidents with 60%> damage are included in that number.
Much lower damage % led to write offs but there was no report that tracks the link.
There also seems to have been no consistent guidance or policy on how the above events should be reported.
