On April 2, 2012, an ATR-72 crashed on UTAir flight 120 ( flight number : UT120) shortly after take-off from Tyumen airport , killing 29 passengers and 4 crew members. 10 passengers survived the crash, seriously injured. The UTair plane was on its way to Surgut .
Aircraft
The aircraft was an ATR 72-200 with the registration VP-BYZ. The age of the machine was 9 years and 5 months.
the accident
The aircraft reached a height of 210 meters, rolled to the left in a 35 ° bank angle and then in a 50 ° bank angle right. The aircraft hit about 2.5 kilometers behind the runway at 7.35 a.m. local time and went up in flames.
causes
The flight data recorder was found in good condition. According to official statements by the investigators, both engines were still working normally until impact.
The aircraft had previously been parked outdoors for 8 hours, with snowfall and temperatures around and below freezing point. In the 90 minutes before the accident, 9 aircraft took off without any problems, all of which had been de-iced . In one of them - also an ATR-72 - 3 cm of ice and snow were found on the wings and tailplane before it was de- iced.
The unlucky machine was not de-iced before it started; even the crew did not insist on de-icing, although they saw snow and ice deposits as they rolled. These deposits can still be clearly seen in photos after the crash. The aerodynamic characteristics of the machine were thus deteriorated so as the climb to the stall came to the pilots did not recognize as such.
Contributing factors:
- Serious deficiencies in the safety management of UTAir, related to documentation and training of crews and ground staff.
- The UTAir ground crew in Tyumen was neither licensed nor qualified for handling. It had only received a 30-minute briefing.
- The pre-flight checks by the ground crew were carried out without the use of ladders, so that the debris could not be seen. The machine was reported as "clean".
- The pre-flight check by the master was only carried out extremely cursory in a few seconds.
- Both pilots were so proficient in English that they were unable to understand the contents of the operating manuals and training documents.
- Possible crew fatigue due to violation of the rules on flight duty and rest times.
