A few extracts from
the link that Airbubba has provided:
The crash site track indicates that the aircraft was first approaching west to exit the airport boundary, but turned right following a technical problem, and had a track showing returning to the airport.
This is a prelim report, "technical problem" details to follow, be amplified, or perhaps be gone once CVR/FDR analysis completed.
The gathered evidence at the crash site shows that impact point with the ground was a recreational park and after the initial impact, other impacts were also observed, wrecking the aircraft fuselage spread across all the track at the accident site.
Parts of this aircraft came down at multiple locations.
The rescue and search operation team found the Aircraft black boxes, including the Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR), and is currently held by the investigation team of Iran AAIB. Both devices have been damaged as a result of the accident and catching fire. The memory parts of both recorders are in good conditions, though the physical damage to their main components is noticeable.
Good news.
A special group was formed and any laser attacks and electromagnetic (radioactive) threats and unlawful actions have been rejected by conducting the relevant sampling and analysis up to now.
A revision may be pending ... but they do rule out a l@ser attack so far ...
An initial notification was sent to Ukraine as the State of registry and the operator, the NTSB as the State of design and manufacture, Sweden (SHK), Canada (TSB), and Afghanistan CAO as the States whose citizens suffered fatal injuries in this accident.
Ukraine requested to participate in the accident investigation process, and introduced a go-team to identify and transfer their nationals' corpses, and perform other responsibilities resting with the country registering and operating the aircraft in such conditions, which has already arrived in Iran.
In accordance with the Annex 13, the investigation team would like to invite all the States involved in the accident to participate in the investigation process.
I have a recommendation for fellow PPRuNers:
please do not impugn the motives of the investigation team nor the Investigating body.
I ask this due to remembering some vitriol directed at BEA in some threads as we all discussed the AF 447 accident and beat the horses dead ...
