The State Bureau of Investigation probing last Friday's An-26 plane crash that killed 26 people on board, including crew and air force cadets, is considering several versions of what could have caused the transport aircraft to plunge during landing, including a terrorist attack.
That's according to the chief of the SBI's Main Investigation Department, Maksym Borchakovsky, RBC Ukraine news agency reports.
According to the official, following the initial inspection of the scene and the study of the radio exchange data of the crew and dispatchers, the investigation has come up with four main versions of the crash cause:
- Technical malfunction of aircraft units;
- Improper performance of duties by crew;
- Improper performance of official duties by persons responsible for flight control; and
- Inadequate aircraft maintenance and flight preparation.
The investigation will appoint an explosives test to confirm or refute the relevant terror attack theory.
Borchakovsky has also refuted the reports of engine failure.
He added that it was only one of the plane sensors that failed, namely a pressure sensor.

What is more, Borchakovsky said the investigation might publish transcripts of radio communications between the pilots and the tower to remove insinuations.
He said about 50 persons, including the only survivor, the air force cadet, had already testified to the SBI.
The bodies of cadets killed in the crash will be handed back to their families before the end of the week after DNA tests are completed.
