1.9 the cause of the Iranian passenger plane crash.

A spokesman for the state-run Iranian Airlines said: "We are investigating the cause of the plane crash, but bad weather should be the main reason."

An official of the Iranian Ministry of Communications said that two black boxes of the plane had been found, which would be of great help to the investigation of the cause of the plane crash.

According to the current information, due to the bad weather, the departure time of the passenger plane flying from Tehran to the northwest was delayed by 65,438+0 hours, said Laluz Kumlai, a police officer in West Azerbaijan province near the crash site. Therefore, the accident is likely to be caused by natural factors, and it is not excluded that the pilot's operational mistakes or comprehensive factors lead to the crash under the action of bad weather.

However, Kumlai said that there is no terrorist factor in the accident for the time being, so the possibility of terrorist attacks can basically be ruled out. At 65438+ 19: 45 local time, the Boeing 727 of Iraqi Airways crashed near Urmiyah, a city in northwest Iran, due to mechanical failure. The plane failed to land at Urmiya airport for the first time, then went around and suddenly disappeared from the radar screen when preparing for the second landing near the airport. According to witnesses, the plane broke into pieces, but it didn't explode.

The plane flies regularly from Tehran to Urmiyah. There were 105 people on board, including crew 12 people and 93 passengers. The plane crash has caused 77 deaths, 27 injuries and 1 passengers missing. 12 crew members were all killed.

Less than an hour after the plane crashed, rescuers rushed to the scene to rescue. However, the local snow is as deep as 70 cm, and the dense fog is pervasive, which brings great difficulty to the rescue.

An official of the Iranian Ministry of Roads and Transport said that one of the black boxes of the passenger plane had been found. "When we have a detailed inspection of the black box, we will announce the cause of the crash of the passenger plane." An investigation team led by Iraqi Minister of Roads and Communications Hamid Bebahani has also rushed to the scene of the accident.

Iranian officials blamed international sanctions for the crash of the passenger plane. The official said that Iran bought more American-made passenger planes before the Islamic Revolution in Iran in 1979, and it was difficult for Iran to buy new passenger planes from the United States and Europe after the two countries broke off diplomatic relations. In order to maintain the operation of the existing passenger plane, Iran often disassembled the parts of this aircraft to make up for the shortcomings of that aircraft.

It is reported that Iran is solving the problem of upgrading passenger planes through a combination of international procurement and independent research and development. Iran recently purchased a batch of Boeing MD series and Airbus aircraft, and this year Iran began to produce the Iran-140 passenger aircraft independently developed. It is reported that Iran-140 is a twin-engine turboprop aircraft, which can carry 52 passengers and has a cruising range of 1865 miles. The head of the forensic department of West Azerbaijan province in Iran said that the Iranian forensic department will publish the list of casualties on the website as soon as possible after verifying the identity. There are no reports of foreign passengers so far. According to the Iranian Embassy, there were no China passengers on the plane. Immediately after the crash, the Embassy asked Teheran Mehra Bader Airport for information. Airport staff confirmed that there were no China passengers on the crashed passenger plane.

Upon learning of the plane crash, Iranian army, Revolutionary Guard, militia, Red Star Moon Society and emergency headquarters rescuers stationed in West Azerbaijan Province quickly rushed to the scene to carry out rescue. There is heavy snow and rainfall in Roumier now. The plane crashed about15km southeast of Romil airport, and the depth of snow reached 50cm, which increased the difficulty of rescue work. Iranian authorities mobilized a large number of machinery and equipment to shovel snow to keep the roads open. Rescue organizations such as the Red Star Monthly Meeting in neighboring East Azerbaijan Province also rushed to the crash site to reinforce.

Shortly after the accident, Iranian Airlines organized an air crash investigation committee to rush to the scene to investigate the cause of the crash. A black box of the plane has been found, and the specific cause of the crash will be announced soon after analysis. Iranian Deputy Minister of Communications Ahmadi majidi said that the crashed plane made an emergency landing for special reasons, not crashed. He said that when the plane arrived in Romil, due to the bad weather and low visibility at the airport at that time, the pilot asked to return, but he lost contact with the ground soon after returning. It is not clear why the pilot was in crash landing at low altitude soon, and the pilot was also killed in the accident. The specific reasons need black box analysis.

In addition, there have been many air crashes in Iran in recent years, the most recent being two major air crashes in July 2009, which caused more than 200 casualties. Iranian public opinion believes that frequent civil aviation accidents are related to low management level and outdated equipment. Some experts in iran air directly point the frequent accidents to the sanctions imposed by the United States and other countries. The plane that crashed this time was a Boeing 727. 1979 After the Islamic Revolution broke out in Iran, the relationship between the United States and Iran deteriorated rapidly. The United States imposed aviation sanctions on Iran, and Iran could no longer buy aircraft and parts made in the United States. At present, the existing Boeing aircraft in Iran are all over 30 years old. Overtime service and the lack of spare parts necessary for maintenance are the important reasons for the frequent crashes of Iranian civil airliners.
