“Human error”, the wrong setting of a military radar, is the “key element” at the origin of the drama of the downed Ukrainian Boeing on January 8 near Tehran (176 dead), according to a report by the Iranian Civil Aviation. “There was a failure due to a human error in the follow-up of the procedure” of calibration of a radar system having induced a “107 degree error” in said system, no longer allowing to correctly apprehend the trajectory of the objects in its field, indicates this report published Saturday evening.

This initial fault “is the source of a dangerous chain [d’événements] which of course could have been brought under control if other measures had been taken. “But according to the CAD document, presented as a” report on the facts “and not as the final report of the investigation, other errors have occurred in the fatal minutes that followed.

The CAD notes that despite the erroneous information he had on the path of the aircraft, the operator of the radar system could have identified his target as an airliner, but on the contrary, there had been “misidentification “. The report also notes that the first of the two missiles fired at the plane was fired by the operator of a defense battery “without having received a response from the coordination center” on which he depended.

The second missile was fired thirty seconds later taking into account “the continuity of the trajectory of the detected target”, adds the report. Ukraine International Airlines flight PS-752 from Tehran to Kiev was shot down on January 8 by two missiles.

The 176 people on board, mostly Iranians and Canadians, but also 11 Ukrainians (including the nine crew members) perished in the disaster.
