American Airlines’s 5342 flight was a way from Wichita, Kansas, and reduced it on Wednesday night and will be landed at Ronald Reagan National Airport in Washington. At that time, it made it made it The last minute of the turnaround rose.
Investigators of the National Transport Safety Commission seemed to be not sure if this means that the pilot was warned by the final decline of the plane. However, the sudden changes in the trajectory are not enough to avoid colliding with a military helicopter that was higher than originally.
“I can tell you at a certain moment when the Security Council member Todd Inman said,” I can tell you at some point that the impact is very close.
In the briefing on Saturday, members of the board of directors provided new information and more details, which revealed the moment when the air collision accident was revealed before. It turned out that this was the most fatal aviation accident in the United States in the nearly quarter century.
According to investigators who recover the information from the flight data recorder, the region’s jet aircraft and the Army Black Hawk helicopter collided between 300 feet and 350 feet on the ground on the Poto Mark River.
This makes the helicopter higher than the height of the height of its specific route near Reagan exceeding 100 feet. The helicopter must fly at the specified height and stay on a specific road to prevent commercial aircraft from entering and leaving busy airports.
The helicopter was approved on the route of flying on Wednesday, called Highway 4, and there was no right to fly above 200 feet.
The New York Times reported earlier that the flight ratio of this helicopter was authorized than authorized, and placed it on the road of jets in the United States Airlines region, killing all passengers on two planes.
One aspect of confusing investigators is that the radar range used by air traffic controllers seems to show the black eagle that shows the black eagle only about 200 feet during a crash on Wednesday night. However, researchers warned that this is a preliminary data that still needs to be verified.
Investigators said they did not know why air traffic control workers had information that was not accurate to helicopters when the helicopter collided.
Mr. Inman said, “This is our job-it is to solve this problem.” “This is what we are doing.”
Investigators also provided detailed accounting with the air traffic communications of the two planes on Wednesday night. According to the Times, a controller uses passenger aircraft and helicopter to handle traffic responsibilities after allowing the second controller to leave the round class earlier than usual.
At about 8:15 pm, US Airlines’s planes left 37,000 feet and began a initial decline. After about 25 minutes, the controller cleared the pilot landing.
At about 8:43 pm, the controller asked whether the crew can be switched from the No. 1 runway to the 33rd runway (the runway 33 was shorter than the runway 1, and the pilot required the strong attention of the pilot landing the plane, previously reported.)
“A brief discussion with the crew, they agreed to switch to the No. 33 runway,” said the NTSB member Brice Banning
Two minutes later, the autonomous driver in jet aircraft was separated.
The event increased by 8:46 PM, and the controller told the helicopter pilot that a passenger splinded around to land on the 33rd runway. Then, the controller cleared another jet aircraft on the runway 1 to take off.
In the next minute, when the passenger plane is about 500 feet from the ground, the controller asked whether the helicopter crew saw the commercial jet, and then indicated that the helicopter passed behind it.
One second later, the plane received an automatic consultation saying: “Traffic. Traffic.”
You can hear some sounds from the aircraft crew at 8:47:58, and the flight data recorder shows that the aircraft began to increase its stadium.
Since then, air traffic control workers will immediately hear the sound of impact.
