The Flight Data Recorder (FDR) and the Cockpit Voice Recorder (CVR) of the Yeti Airlines plane that crashed in Pokhara on January 15 have revealed that both the engines of the aircraft feathered while landing.
According to the commission formed to investigate the accident, the propellers of the aircraft’s two engines feathered when it was on the base leg of its landing procedure. In aviation, this means that the propeller blades were turned to have the leading edges pointed essentially in the direction of flight.
Feathering is employed if a plane’s engines must be shut down.
Issuing a statement on Monday, the probe commission said that it was looking into why both the engines feathered and investigating the possible technical and human reasons that could have caused the situation.
The two recorders, which were recovered a day after the crash, had been taken to Singapore for analysis. Members of Nepal’s investigation commission, Singapore’s Transport Safety Investigation Bureau, France’s Bureau of Enquiry and Analysis for Civil Aviation Safety, Transportation Safety Board of Canada, European Union Aviation Safety Agency and the aircraft engine manufacturer Pratt & Whitney Canada studied the data and examined various aspects of the plane. They also examined the flight and the conditions surrounding it in an ATR simulator.
The Yeti Airlines 9N-ANC plane, carrying 72 people including crew members and flying from Kathmandu to Pokhara, crashed in the Seti Gorge on the day of Maghe Sankranti last month killing all aboard.
On the same day of the crash, the government formed the five-membered enquiry commission led by former Secretary Nagendra Ghimire in accordance with the Civil Aviation (Investigation of Accident) Regulation-2014 to look into what caused the mishap, the worst accident in the history of Nepal’s domestic aviation, and make recommendations to prevent similar disasters in the future.
The commission had been given 45 days to carry out its investigation and submit the final report.
