The ongoing analysis of the flight data recorder retrieved from the crashed Russian A321 aircraft is not helping to shed light on the cause of the tragedy, the Kommersant daily reported Friday, citing sources close to investigation.
Earlier, head of Russia’s civil aviation authority Alexander Neradko said that the parametric recorder that records the flight parameters as well as the work of the plane’s systems and engines had been transcribed and its data has been submitted to specialists for review, while the voice recorder was soon to be transcribed.
"The transcription of the parametric recorder from Kogalymavia's Airbus A321 that crashed in the Sinai Peninsula has not helped to determine the cause of the deadliest civil aviation catastrophe in the history of Russia," the sources said.
According to the sources, the black box showed that during the flight, which lasted just over 20 minutes, all the A321's systems were working properly. However, after "a certain event" the flight data recording was interrupted.
Experts quoted by the newspaper suggested that the crash could have been cause by an explosive depressurization of the plane’s cabin, which made the plane's tail section, where the black box was situated, separate from the fuselage of the aircraft.
On Saturday, the Airbus A321 passenger jet crashed while en route from the Egypt resort of Sharm El-Sheikh to St. Petersburg, killing all 224 people on board.
A variety of possible scenarios have been set out by aviation experts following the accident, ranging from a terrorist act to a technical glitch.

Flight recorders useless in establishing causes of Airbus A321 crash in Sinai.....
ReplyDeleteFlight recorders of the Airbus A321 that crashed in Egypt will not help establish the cause of the tragedy. The black boxes of the aircraft contain the recordings that end abruptly, shedding no light on any problems in the work of the aircraft equipment.
Experts note that the instantaneous crash of the aircraft could occur as a result of the separation of the tail of the aircraft, where a flight recorder was installed.
"The catastrophic situation on board was developing so fast that the pilots most likely had no time to react to it. Therefore, the content of the voice recorder is likely to be useless as well, taking into consideration the fact that the recorder was severely damaged," the Kommersant newspaper wrote, Pravda.Ru reports.
According to the records obtained from the black boxes of the Airbus A321, all systems of the aircraft were operating normally throughout the whole flight that lasted for 23 minutes. The plane was about to gain the required altitude for the assigned flight level, when something happened on board.
The instantaneous shutdown of the flight recorder can be connected to the explosive depressurization of the cabin that resulted in the separation of the tail part of the aircraft........ http://english.pravda.ru/news/russia/06-11-2015/132516-flight_recorders_airbus_sinai-0/#sthash.K35tRFnC.dpuf
