I am confused. See footnote 3 in the report page 11:
3 In the mentioned requests for flights on April 7 and 10 for the Tu-154M aircraft the same PIC was specified who was the chief of squadron. Actually, the flight of April 7 was performed by him, but on April 10 (during the accident flight) the PIC’s duties were performed by another pilot who was co-pilot in the flight of April 7.
Does it say that Protasiuk was the FO on the PAF Tu-154M flight on April 7? Or does it say that he was
specified as the FO for the 10 April flight (accident)
in the request?
Edit: Oh, sorry, Page 21, just above the passage discussed three posts before:
Thus, on April 7, 2010 the PIC flew to Smolensk "Severny" Airdrome as a co-pilot.
