MOSCOW. Aug 4 (Interfax) - The Interstate Aviation Committee (IAC) Technical Commission's investigation into the April 2010 Lech Kaczynski plane crash near Smolensk is completed, the commission's chairman Alexei Morozov told reporters in Moscow on Wednesday.
"I confirm once again that the IAC Technical Commission has completed its work," he said.
The commission's ultimate report on the results of the investigation is considered legally complete the moment it was published, Morozov said.
The ultimate report supplemented with Poland's remarks was sent to the Russian State Commission and to Warsaw, Morozov said.
The report, the Polish remarks and all the necessary materials were sent to the Russian Investigative Committee for a subsequent criminal investigation as required by Russian and international laws, he said.
"As for future cooperation with Polish colleagues, we are always open to it at international forums and on a bilateral basis," the official said.
On Friday, Poland presented its own official report on the causes of the Kaczynski plane crash. The report states that the crew was poorly trained, but it also mentions the shortcomings at the Smolensk Severny airfield.
IAC retorted that the airfield's condition could not be the cause of the crash.
Earlier, Morozov told reporters that the crash occurred through the crew's failure to decide to use a backup airport after being informed about bad weather in Smolensk.
In January 2011, IAC published the results of its technical study of the crash.
