UPDATE 1-Canada says there are no firm plans for downloading black boxes from crashed jet

There are still no firm plans for downloading the cockpit and flight data from a Ukrainian airliner which was shot down by Iran 10 days ago, Canada's Transportation Safety Board (TSB) said on Sunday.

The TSB said in a statement that two of its crash investigators had left Tehran earlier on Sunday after a six-day visit during which they examined the wreckage. A total of 176 people died in the disaster, 57 of them Canadian citizens. Iran is trying to analyze the black boxes, the state IRNA news agency reported on Sunday, denying a report that a decision had been taken to send the plane's recorders to Ukraine.

The TSB said it understood the boxes were still in Iran and added: "There are still no firm plans as to when and where the aircraft recorders will be downloaded and analyzed". Canadian Prime Minister Justin Trudeau on Friday called on Iran to send the boxes to France, which he said was one of the few nations with the ability to read data from the damaged fight and cockpit recorders.

The TSB said the chief Iranian investigator "may travel to Ukraine this week" for talks with the National Bureau of Air Accidents Investigation of Ukraine and to visit its laboratory.
