The Interstate Aviation Committee informs that according to the information received HS-125-800 RA-02807 aircraft operated by S-Air Airline (Russia) crashed during the approach in Minsk-2 Airport (Republic of Belarus) on October 26, 2009 at about 22:30 Moscow time. 3 crew members and two passengers on board were killed.
In accordance with the Agreement on Civil Aviation and Use of Airspace, which members are Belarus Republic and Russian Federation as well accident investigation is conducted by the Investigation team of the Interstate Aviation Committee with participation of official representatives of Belarus and Russia aviation authorities. Investigator in charge – head of the accident investigation division of the IAC Investigation team – Goryunov Boris Alexandrovich – the Investigation team departed to the accident site.
Investigator in charge of the fatal accident with HS-125-800B RA-02807 aircraft informs that the Investigation team has been fully established and continues its activities at the accident site. The activities are focused on flight recorders search, sketch-maps development and preparation for evacuation of remained aircraft fragments and engines.
Sub-groups and working groups which proceeded to activities focusing on:
- studying of flight operation management in airline and evaluation of the crew proficiency level;
- compliance with maintenance documentation requirements and analysis of aircraft, engines and systems technical state;
- readout and analysis of ground-based recording facilities. Analysis of ATM specialist’s work and radio navigation facilities operation;
- analysis of weather conditions.
In accordance with Annex 13 to the Convention on International Civil Aviation notification about the accident are sent to the states of aircraft design (USA) and manufacture (Great Britain).
Investigator in charge of the fatal accident of HS-125-800B RA-02807 aircraft informs that both recorders (FDR and CVR) were detected in the progress of activities at the accident site on October 28. Visual inspection indicated that both recorders were exposed to intensive fire resulted fr om aircraft collision with obstacles.
Soon the recorders will be delivered to the Interstate Aviation Committee laboratory wh ere their opening and inspection will be carried out. Methods and techniques of data recovery and reading will be determined following the results of these activities.
Investigator in charge of the fatal accident with HS-125-800B RA-02807 aircraft informs that the Investigation team continues its activities at the accident site. Official representatives of the USA (states of aircraft design and states of engine design and manufacture) and Great Britain (state of aircraft manufacture) are arriving in Minsk today. In accordance with provisions of Annex 13 to the Convention on International Civil Aviation, the experts will take part in the Investigation team work.
Investigator in charge of the fatal accident with HS-125-800B RA-02807 aircraft informs that the Investigation team continues its activities at the accident site. Remained aircraft and engine fragments evacuation from the accident site for their further layout is initiated.
Opening of aircraft flight recorders was carried out in the Interstate Aviation Committee laboratory. Analysis of flight recorders (magnetic tape) condition indicated that they sustained significant thermal damage which resulted in tape buckling and sticking followed by integrity loss. Due to significant damage of flight data recorders the experts are planning to carry out the range of activities on their recovery. Activities can take 2-3 weeks.
Investigator in charge of the fatal accident with HS-125-800B RA-02807 aircraft informs that it was possible to fully restore CVR tape with a help of AAIB UK experts.
Primary analysis of recording indicated that there is information concerning abnormal case occurrence and development in flight on 26.10.2009. Recording quality is low but it is good for further decoding. Experts proceeded to development of crew speech protocol, sounds identification and CVR recording synchronization with ground-based recording facilities data.
Analysis of FDR magnetic tape indicated that due to extensive temperature exposure tape turns exposed to complete "consolidation". Tape and data recorded on it can not be restored.
