Human error related to lever mix-up may be later than last month Yeti Airlines crash A preliminary report said 72 people died on board.
Yeti Air Flight 691, en route from Nepal’s capital Kathmandu to the tourist city of Pokhara, crashed minutes before landing on January 15.
The twin-engine ATR 72 aircraft carried 72 people on board, including 2 infants, 4 crew members and 10 foreigners. Rescuers have recovered 71 bodies of him and one passenger is still missing but presumed dead.
Less than two minutes into the fatal crash, Captain Anju Katiwada requested the plane’s flaps be extended by saying “flaps 30” and co-pilot Kamal KC said, “We are descending on flaps 30. ’ he replied. In a 13-page bulletin released Wednesday,.
However, the flight data recorder “was not recording the movement of the flap surface at that time.”
Instead, the propeller rotation speed of both engines decreased and the torque started dropping to 0%. This suggests that one of his pilots may have accidentally moved the power-hi lever instead of the lever controlling the flaps. There was no engine thrust to propel the plane forward.
Buddhi Sagar Ramichane, joint secretary of the tourism ministry, told the Kathmandu Post that the investigative panel was still investigating why the pilots delayed deploying the flaps and why they did not follow the regular checklist. Told.
Earlier this month, the commission said analysis of cockpit voice recorders and flight data recorders showed the propellers on both engines were in the feathered position.
“When both propellers were feathered, the research team confirmed that both engines of the 9N-ANC were operating at flight idle to prevent over-torque during event flight,” said Tourism. A report published on the Ministry of Culture’s website said: and Nepal Civil Aviation.
When air traffic controllers in Pokhara cleared the flight to land, Hatiwada said twice that the engines had no power, according to preliminary reports.
The fateful flight was operated by Khatiwada, who was in the process of acquiring airport proficiency for operations in Pokhara, and KC, who had been the instructor pilot for his third training flight that morning since the previous round trip. .
