Narrative:
Ukraine International Airlines flight 752, a Boeing 737-800, crashed near Sabashahr, 7 minutes after takeoff from Tehran Imam Khomeini International Airport, Iran. Al 167 passengers and nine crew members on board were killed.
The Boeing 737-800, registration UR-PSR, had landed on schedule at 00:57 hours local time at Tehran. The return leg back to Kiev was due to depart at 05:15 local time (01:45 UTC).

In the meantime, around 02:15 hours local time in Iran, numerous ballistic missiles were fired from Iran towards U.S. bases in Iraq in response to the killing of Major General Qasem Soleimani by a United States drone strike.
As a result this military operation changed the alertness level of Iran’s air defense. At approximately 04:00 the military sector informed the civil sector of the country’s Airspace Control that only the flights already detected and cleared for flight operations by the defense network could be permitted to start up. This would ensure the correct identification of civil flights by the defense network and avoiding targeting them by mistake.

At 05:49 the doors were closed and the aircraft was ready to depart. Two minuts later the flight requested the to start up the engines.

After contacting the Area Control Center, the ATC unit requested clearance for the Ukrainian flight at 05:52. The Area Control Center forwarded the request for flight PS752 to the Air Defense Coordination Center, which subsequently issued the clearance accordingly.

The aircraft then taxied to runway 29R and commenced the takeoff roll at 06:11. After takeoff the flight contacted Mehrabad Radar and was cleared to climb to FL260 and turn right after reaching 6000 feet, heading direct to the PAROT reporting point.
As the aircraft was climbing after departure, it appeared on the air defense system. However, a wrong initialisation procedure of the system’s north alignment had induced a 107-degree error in the system. Thus, the direction of objects and targets detected by this system was being observed with an increase of 107 degrees by the operator.
At 06:13:56, the air defense unit operator detected a target at his 250-degree azimuth, flying on a 52-degree course. At the same time, PS752 had been flying towards the defense system from a 143-degree azimuth. The aircraft was flying a 309-degree course.

At 06:14:21, the operator notified the specifications of the detected target to the Coordination Center over the communication network. The notification was not communicated successfully.

Meanwhile the system operator began analyzing the observable information and categorized the detected target as a threat. At 06:14:41, without receiving any response from the Coordination Center, the air defense unit operator fired a missile at the threatening target he had detected.

Under the applicable procedures, if the defense system operator cannot establish communication with the Coordination Center and does not receive the fire command, they are not authorized to fire.

The missile radio fuse was activated at 06:14:59. At that point flight PS752 was at 8100 feet at a position about 20 km west-northwest of the airport.

After the first missile radio fuse was activated, the air defense unit radar still locked on the target, and the defense system kept detecting and tracking it. By observing the continuity of trajectory of detected target, the second missile was fired at the aircraft by the operator of defense system at 06:15:11.

At 06:45:24, the last communication between the missile and the defense system was recorded in a place close to the aircraft route. After that, the defense system showed a message indicating the strike had failed, with the aircraft clearing from the radar lock-on after some time.

The aircraft turned to the right and about 06:16:11, a fire broke out on the aircraft, which was intensifying. Altitude was lost and at 06:18:23, the aircraft crashed into a playground in Khalajabad near Shahedshahr area, 15 km north of the airport. It disintegrated completely and wreckage was strewn along a 300 m long path.

Canada urges to disclose analysis of UIA plane recorders

Canada urges to disclose analysis of UIA plane recorders

Canada urges experts to disclose information obtained after analyzing the flight recorders of the UIA plane shot down by Iran.

“Canada thanks BEA [Civil Aviation Safety Investigation Authority] for completing the download and analysis of Flight PS752’s black boxes. That analysis now needs to be shared promptly with the international community to ensure a complete, credible and transparent flight safety investigation,” Canada’s Minister of Foreign Affairs François-Philippe Champagne posted on Twitter.

In accordance with Annex 13 of the Convention on International Civil Aviation, Iran can use the information obtained as a result of black boxes’ analysis of UIA plane at its own discretion.

Canadian and other foreign experts were present in Paris at the download and analysis of flight recorders but could not share the information with the public without permission.

The Ukraine International Airlines (UIA) plane (flight PS752) heading from Tehran to Kyiv crashed shortly after it took off from the Imam Khomeini International Airport at about 06:00 Tehran time (04:30 Kyiv time) on January 8. There were 176 people on board – nine crew members (all Ukrainians) and 167 passengers (citizens of Ukraine, Iran, Canada, Sweden, Afghanistan, Germany, and the UK). All passengers and crew were killed in the crash.

On July 18, France’s BEA received Flight PS752’s recorders from Iran.

On July 24, Deputy Foreign Minister of Ukraine Yevhenii Yenin informed that the transcript from Flight PS752’s recorders had confirmed illegal interference with the plane.

Ukraine: Black boxes confirm interference with jet downed in Iran

The transcript from the black boxes from a Ukrainian jet accidentally shot down by Iran on January 8 confirms the fact of illegal interference with the plane, according to Ukraine’s deputy foreign minister.

Yevhenii Yenin’s remarks came on Friday, a day after an international team examining the flight recorders from the jet had completed a preliminary analysis of the data in France.

“Grateful to all partners who helped bring this moment closer. Black boxes from #PS752 were read out and deciphered successfully. The transcript confirmed the fact of illegal interference with the plane,” Yenin wrote on Twitter.

He also said Kyiv was expecting an Iranian delegation to visit Ukraine next week for talks.

Iranian forces say they downed the Ukraine International Airlines Boeing 737 jet after mistaking it for a missile at a time of high tensions with the United States. All 176 people on board were killed.

Ukrainian Foreign Minister Dmytro Kuleba said this month that it was too soon to blame human error for the shooting down of the airliner and that many questions remained unanswered.

International probe

A team of investigators from the same countries as the victims of the plane crash met this week at France’s Bureau for Enquiry and Analysis for Civil Aviation Safety (BEA), in Paris, to begin extracting the data.

“The download and preliminary data analysis was an important milestone in what must be a thorough and transparent safety investigation,” said Katy Fox, the chair of the Transportation Safety Board (TSB) of Canada, on Thursday.

“The work in Paris is finished, but the investigation is far from over. There are still many key questions that need to be answered,” she said in a statement.

“We have urged Iran to release factual information from the recorders as soon as possible,” Fox said, adding that Iran – which is leading the investigation – has not authorised the TSB to release details.
