Nepal plane crash preliminary report: Investigators suspect human error
The Hindu
According to the preliminary report, the flight crew had made two flights between Kathmandu and Pokhara earlier in the morning. The flight that crashed was the third in a row by the same crew.
The Yeti Airlines aircraft which crashed in Nepal last month killing 71 people, including five Indians, lost thrust and fell after the propellers of both engines went into a feathered position, according to a preliminary probe report which lead investigators to suspect human error behind the deadly crash.
Yeti Airlines flight 691, after taking off from Kathmandu's Tribhuvan International Airport on January 15, crashed on the Seti River gorge between the old airport and the new airport in the resort city of Pokhara.
There were 72 people including four crew members onboard the ATR-72 aircraft when it crashed, but rescue officials have so far managed to recover only 71 bodies with the other missing passenger presumed dead.
It is rare for the propellers of both engines to come to a feathered position, said one of the members of the five-member probe committee, which is also mentioned in the 14-page preliminary report posted on the website of 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,” said the member on condition of anonymity.
“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,” states the preliminary report.
“As per the Flight Data Recorder (FDR) all the recorded parameters related to engines did not show any anomaly,” adds the report.
