It’s been a month since the Chinese plane crashed with 132 people, the mystery still surrounds

Pilot in The crash of a plane carrying 132 people meets Chinese standards for flying commercial aircraft. No problems were detected with the aircraft prior to take-off. No dangerous goods were carried on this flight. Communication with the plane remained normal until the plane went down.

Preliminary report on the downing of China Eastern Boeing 737-800 aircraft released by China’s aviation safety regulator on April 20. However, the report could not explain many mysteries about why the plane suddenly lowered its nose in clear weather and plunged into the hills, killing all 132 people on board, the New York Times pointed out. out.

“The investigation found that the flight and crew on board, as well as maintenance and clearance personnel, met the qualification requirements. Before the aircraft deviated from cruising altitude, there was no abnormality in crew communication with air traffic control or in operating commands,” the report states.

The report of the aviation authority of China also said that collecting more evidence from 2 Black box of crashed plane may need more time. The report notes, two black boxes were severely damaged in the crash. Data recovery and analysis from these black boxes is ongoing.

China is a signatory to the Convention on International Civil Aviation, so the Chinese aviation regulator is obliged to provide a preliminary report by April 20, 30 days after the accident. The report submitted by the Civil Aviation Administration of China does not offer any theory to explain the sudden almost vertical fall of the Boeing 737-800 while flying at an altitude of more than 8,800 meters.

Commercial aircraft are designed for natural front-to-back stability in flight. Aviation experts point out, the plane almost does not plunge straight down at very high speed unless there is a strong force on the stabilizers on the sides of the tail.

A mechanical or software error could cause the stabilizer to malfunction, or the pilot could intentionally manipulate the plane to make the plane nearly go straight down. The report does not address these possibilities but notes that important components of the tail section have been found in the impact crater left by the plane on the hillside. The plane’s engine was also found in the crater.

Earlier this month, Wu Shijie, a safety official with the Civil Aviation Administration of China, warned when there were many theories about the accident. catastrophic air accident went viral in China. Some theories suggest that the pilot’s suicide was the cause of the crash. China’s aviation authorities have stepped up health and mental health checks of commercial airline pilots in recent days.

But this measure against the pilot should not be taken as an indication that the cause of the accident has been determined, Wu noted. “We are still unable to draw conclusions about the cause and nature of the accident,” he stressed.

China has complied with international standards for air accident investigation. The country has sent both black boxes to the National Transportation Safety Board in Washington, USA for analysis.

The US Aviation Administration has also sent a team of experts to the crash site in southern China to help with the investigation. China allowed a group of experts to enter the country without having to quarantine for 3 weeks as usual. American experts follow the “commuting bubble” that was applied in Beijing Olympics this year.
