The accident investigation team, led by the National Transportation Safety Board (Transportation Safety Board), also provided "black box" records on the afternoon of July 7, when the plane crashed in the San Francisco airport and landed too fast, After the attempt to take off, the tail of the plane crashed into the breakwater caused the accident.

local time July 6 11:27, the Hana Air OZ214 Flight at the San Francisco airport runway 28th occurred during the landing. The flight has a total of 291 passengers, including 77 Korean passengers, 141 Chinese nationals, 64 U.S. Nationals, 3 Indians, Canadian 3, French nationality, Japanese and Vietnamese 1. At present, 2 people have been confirmed dead and 182 injured, of which 49 were injured.

Two passengers were Chinese nationals.

Pilot error or become the focus of investigation

The U.S. National Transportation Safety Committee Chairman Hussman (Deborah Hersman) announced two "black Box" records: 214 on the 28 left runway, landing gear down, flaps down 30 degrees, and entry speed at 137 knots, the Christian Science Monitor said 7th ( About 253.724 km/h), and no abnormalities.

The Safety Committee's initial analysis of the flight data and cockpit recorder showed that everything was normal before the plane had a 7-second landing, and the pilot did not mention any problems with the plane or any concerns about visual entry.

In the first 4 seconds of the crash, a stall warning was issued by the automatic rocker, indicating that the aircraft was losing its aerodynamic lift.

It was not until 1.5 seconds before the impact that the crew took action to lift the engine significantly, attempting to take off again and land again, while the throttle and engine were normal.

According to the Wall Street Journal, Hussman said the cockpit crew did not find the aircraft flying too slowly until then. The plane's landing speed was far below the specified entry speed of about 260 kilometres per hour. However, the engine seemed to react normally to these instructions, but it was too late, the tail crashed on the breakwater, the plane slid hundreds of yards forward, and the engine and wing fell off.

Investigators say the plane crashed at a dangerously low speed and the pilot did not have time to correct it, although Hussman said it was not certain that the pilot's failure was the cause of the crash, but investigators focused on two aspects: one is why the cockpit allows the Boeing 777 to be so slow; The second was that no decisive action was taken until 2 seconds before the landing.

South Korea's central Daily reported that the South Korean Ministry of Land, said the air crash is likely due to the South Korean airlines internal training problems.

Hana in South Korea time July 7, the press conference said the crash flight has 4 pilots, of whom 3 are experienced captains, the total flight time of more than 10,000 hours, the other deputy captain of the total flight time is also close to 5,000 hours.

The results of the investigation revealed that, when the accident occurred, the deputy Captain Li Qiangguo was sitting in the captain's seat, and Li Power flew the model only 43 hours.

Or because of the experience of the crew members, Hussman will emphasize that the unit did not send distress signal before the incident, and the crew should be able to rely on the ground and aircraft landing aid system to establish a landing channel, safe to reach the starting point of the runway.

Li, the "novice", has been questioned by the control lever for improper operation.

But Hana held a press conference on the aircraft pilots lack of qualifications, said not to allow the relevant speculation, the captain on duty experienced, excellent skills, involved pilots are trained according to international practice. The exact cause of the plane crash is still unknown, and must wait for the black box to interpret and then judge.

Fuel system Problem not identified

A 2008 Boeing 777 aircraft operated by British Airways (Airways Airways) landed at London's Heathrow International Airport (Heathrow Analysys Airfield) during a previous abdominal landing. The aircraft failed at the same time 150 meters above the landing, and did not respond to the driver's acceleration instructions.

Post-investigation reports indicate that the accident was related to the ice of the aircraft fuel system. British Airways flight 38th flew from Beijing to London, and the temperature around Mongolia and Siberia was low to 零下74摄氏度. Fuel does not solidify, but one out of 10,000 of the water is solidified, forming soft ice, along with the fuel flow plug the fuel heat exchanger, resulting in serious engine oil shortage, the aircraft lost power.

Hussman said investigators have yet to ascertain any similarities between the crash and the last British Airways incident. The last British Airways incident was powered by RO engines, and this time it was a whirlpool engine.

One industry personage said to the reporter, also cannot rule out with the last British airlines accident similar. Because no engine manufacturer has indicated that it has completely solved the problem.

"The GE engine also caused Air China to fly to Paris Flight 2 as a child to make a landing in Irkutsk, this year, there was an Air China 777-300 fly to Paris on a single stop, had to make a landing in Stockholm." "The slow descent is just a strain, not a cure," the industry said. ”

Yun Yongdou, the chief executive of Hana Airlines, said the crash was purchased in March 2006, and that the aircraft had been involved in the Osaka route before departing for San Francisco from Incheon without any problems with the maintenance process. The aircraft also had regular scheduled maintenance in June and did not find any engine or mechanical failure.

Boeing, the aircraft manufacturer, also responded that it had actively cooperated with the investigation team to send a technical team on the scene, and said that 18 years, Boeing 777 as the safest model has never been a fatal accident, the current ranking of the world's top airlines have 777 models in operation. "777 is the best plane in a two-channel plane in every way," he said. Boeing said.

But because of the accident, South Korea's Ministry of Land said the South Korean government will be from 8th onwards, all airlines in South Korea's Boeing 777 aircraft engine and landing equipment for security checks. The inspection will last for 50 days, and the Korean government will conduct special security checks on 8 airlines such as Hana Air, Korean Airways, Jeju Airlines, Real Aviation, Busan Airlines, Lois Air, air and Incheon Airlines.

will be inspected a total of 48 Boeing 777 aircraft, 37 Korean Airways, 11, Hana Air.
