The AZAL plane that crashed near Aktau was exposed to external impact before it hit the ground, says the preliminary report of the Ministry of Transport of Kazakhstan on the known plane crash, APA reports.
"Due to adverse weather conditions the aircraft unsuccessfully attempted to land in Grozny two times, and then the captain decided to return to Baku. Following this decision, the (CVR) recorded two external noises, occurring with 24 seconds interval, over Grozny.
Analysis of the CVR and FDR data showed that, 4 seconds after the first external noise the 3rd hydraulic system failed, followed by the failure of the 1st hydraulic system 6 seconds later, and the 2nd hydraulic system 21 seconds later.
Numerous through and blind damages were found on the fuselage, photos and video recordings were taken. The number of such damages were particularly high in the AFT part of the aircraft, including the vertical and horizontal stabilizers. Moreover, some of them were found in the left wing, and the left engine.
Foreign objects that did not belong to the aircraft structure were discovered in the wreckage damages, and photos of these objects were made available to the public in the preliminary report. Additional expert examinations will be carried out to determine the exact origin of these objects," noted in the report.
