plane

The Boeing 777-200ER machine with aircraft registration HL7742 was delivered on February 25, 2006 and put into service on March 7, 2006. The aircraft was powered by two Pratt & Whitney PW4000 engines.

After the almost eleven-hour flight from Incheon , the aircraft made a visual approach - the airport's instrument landing system (ILS) was out of order due to a defect - to land on runway 28L, which protrudes into the Bay of San Francisco . According to initial evaluations by the flight recorder , it fell well below the target speed of 137  knots (254 km / h). The landing gear was extended, the position of the landing flaps was 30 degrees. About seven seconds before the impact, one of the crew members asked to increase speed. The stall warning system started four seconds before the impact. 1.5 seconds before the impact, a crew member requested the go- around . According to initial interviews, the pilot in charge assumed that the automatic throttle control (autothrottle) would maintain the speed. As it turned out in December 2013 during a hearing before the NTSB , however, this was switched off.

According to several eyewitnesses, the plane took off too low. Its stern hit the bank reinforcement in front of the runway. Parts of a landing gear were found in the water. The tail section with the tail unit was separated from the aircraft by the impact. The two parts of the horizontal stabilizer and the vertical stabilizer remained before the landing threshold are the slopes. The rest of the aircraft began a few seconds after hitting the runway to turn left around the vertical axis . The right wing and tail were raised before the aircraft sank back to the ground. About 700 meters from the location of the first impact on the shore line, the wreck came to a standstill to the left of the runway. An amateur video that shows the course of the crash landing out of focus reveals a reddish cloud of dust as soon as you leave the asphalt runway. Eyewitnesses initially thought it was a ball of fire. Later, the NTSB published recordings from cameras at the airport. The large holes on the upper side of the aircraft fuselage were not created immediately during the crash landing, but rather as a result of a fire after the evacuation, in which the aluminum alloy melted.

Immediately after the crash landing, the crew announced an emergency by radio and called for rescue workers. Only the evacuation slides on the left side of the aircraft were used to evacuate the passengers. The pressure bulkhead at the stern had a large hole through which several passengers could escape into the open. Numerous people were able to leave the aircraft on their own before the passenger compartment caught fire and burned out. All three dead were found outside the wreck. Ye Mengyuan, one of two unangeschnallt what has been teenagers was rolled under the extinguishing foam invisible from a fire engine. The incident was classified as a tragic accident after an investigation and the prosecution of the driver of the fire engine was discontinued. In conclusion, however, it was determined that Ye, who was in the back row, was probably killed by the door behind her that had come loose after her chair fell over, and was already dead before the fire truck ran over her.

After the accident, the airport was closed for several hours. According to information provided by the airport, runways 01L / 19R and 01R / 19L were opened again during the day of the accident and runway 10L / 28R during the following day. Runway 10R / 28L was confiscated by the NTSB until Thursday and remained closed until July 12, 5:05 pm local time (July 13, 2:05 am CEST). The wreck was temporarily transported from the scene of the accident to a remote area of ​​the airport using flatbed trucks.

causes

In the final report of the National Transportation Safety Board (NTSB) accident investigation authority, the pilots are blamed for the crash landing. Due to the failure of the ILS, the landing had to be done in visual approach. The pilots would have relied too much on the machine's automatic safety systems; they "relied too much on systems that they did not fully understand and lacked manual flying experience". When it was noticed that “something was not going right”, the go - around was initiated too late due to communication errors between the crew members .

The aircraft manufacturer Boeing is also blamed for the accident. The automatic systems of the aircraft would lull the pilots into a false sense of security and their complexity was insufficiently described. The American traffic authority and also European aviation safety authorities had already made Boeing aware of the problem after other, similar events.

Effects

  • Asiana Airlines has been requested by the NTSB to revise the training program for their pilots to practice both automatic and manual operation more intensively during normal flight conditions.
  • Boeing has been requested by the NTSB to revise the training program and training manual for automatic thrust control.
  • Boeing has been asked by the NTSB to develop changes to the automatic flight control systems to ensure the planes always have enough power to stay in the air.
