Is there no English translation available for this Report?
Not so far. You can copy and post the text into bing translate, page by page. The result is pidgin but, understandable. I have read that: " It crashed, 20 killed, ISA+16, no fire, unsurvivable. Subsequently, they have found corrosion, poor repairs, unregulated parts, unsegregated stock, all engines working at impact, fuel on board. The Flying permits for the other two aircraft are withdrawn. The full report will address all aspects of the accident".
It is sad reading. However, there is no attempt to describe the cause of the accident that I can find in this interim report.
