KATHMANDU – The Yeti Airlines According to reports, a Nepalese aircraft crashed into the Nepali mountains last month, killing 71 people. Five of those killed were Indians. preliminary Probe report that leads investigators suspect human error The deadly truth behind it crash.
After taking off from Yeti Airlines, flight 691 took off. Tribhuvan International Airport in Kathmandu On January 15, the aircraft crashed in the Seti River Gorge between the old and new airports of the resort city. Pokhara.
The ATR-72 plane crashed with 72 passengers and four crew aboard. Rescue officials were able to retrieve 71 bodies, while the missing passenger is presumed dead.
One member of the probe committee said that it is very rare for both propellers to become feathered. This is also mentioned in the 14 page document. preliminary The report was posted to the Ministry of Tourism, Culture and Civil Aviation of Nepal.
“Human factor in the accident could not be disregarded. So it is an issue of investigation,” On condition of anonymity, the member said.
“When both propellers were feathered, the investigation team observed that both engines of 9N-ANC were running flight idle condition during the event flight to prevent over torque,” The states preliminary report.
“As per the Flight Data Recorder (FDR) all the recorded parameters related to engines did not show any anomaly,” Adds to the report.
“When Air Traffic Controller (ATC) gave the clearance for landing at 10:57:07, the Pilot Flying (PF) mentioned twice that there was no power coming from the engines,” Further information is provided in the report.
“During the time of the crash, the prevailing visibility was 6 km and the sky was almost clear with only a few clouds,” These are the points to be aware of preliminary report.
Experts claim that pilots accidentally pulled the condition levers which caused the engine to stop and feather its propellers. Every lever controls its engine’s idle speed and starts or stops fuel supply.
A one-year old investigator claimed that the levers had been pulled to the ground at the scene. crash site.
“We are waiting for a detailed report. We cannot ascertain what happened before that,” One member of the probe panel said this.
“Yes, there is also the issue of flaps. There are questions about why the pilots delayed extending the flaps. The routine checklists were not followed. There are many factors to look at,” The Kathmandu Post quoted Buddhi Sagar Lamichhane, Joint Secretary of Tourism Ministry and a top member of the probe team as saying these words.
International Civil Aviation Organisation, (ICAO) requires that a state investigating an incident or accident must provide a report. preliminary Report within 30 days.
It is expected that the final report be completed within twelve months from the date of accident. The following is the preliminary Report that the crew made two flights from Kathmandu to Pokhara It was earlier in the morning. It was the third time in a row that the crew crashed the plane.
Two captains were aboard the aircraft. Captain Anju Khatiwada Was in the process to obtain an aerodrome proficiency certificate for operation in PokharaInstructor pilot was Captain Kamal KC.
You will need to take off, climb, cruise and descend. Pokhara were normal.
The pilots raised the flaps at 15° and moved the landing gear lever down to 10:56:12. Khatiwada At 721 feet, the Autopilot System was disengaged. Khatiwada was then called. “FLAPS 30”Captain KC answered, “Flaps 30 and descending.” At that point, the FDR flight data recorder did not capture any flap surface movement.
According to the report, both the propeller rotation speeds of the engines dropped to less that 25%. The torque which causes the opposite rotation started falling to zero percent.
Propellers with feathers don’t create thrust, which propels the aircraft forward. The flight data recorder found no anomalies in any parameters related to engines.
Captain Khatiwada mentioned twice to the air traffic controller that the engines were not running when he gave clearance to land.
It was reported that the certificate of airworthiness for the aircraft had been valid up to April 24, 2023.
Singapore’s Transport Safety Investigation Bureau has offered analytical assistance to Nepal’s Investigators.
China assisted in the construction of this airport. It was opened quickly and it is still being used without proper preparations for January 1, project deadline. All equipment has been tested at the new airport’s flight calibration. They have yet to recommend landing in the west. The calibrator report is scheduled to be released on February 26.
The flight procedures have not been made public. Experts say that airlines have little data and information regarding airport procedures. According to experts, the AAIC stated that additional investigation would focus on the conditions under which the propellers were feathered. human Media reports include information about factors and visual approaches, as well as simultaneous operation at both international and national airports.
