A Nepal government-appointed inquiry to investigate the Yeti air crash, said in its report that a lack of thrust in the aircraft's engines during the final leg of its descent caused the accident, media reported on Tuesday.
Citing a statement from the panel, the media report said analysis of the cockpit voice recorder and flight data recorder showed the propellers of both engines on the ATR-72 turboprop were feathered before it crashed near Pokhara.
The expert explained there was "no thrust" in the engine or that it did not produce any power.
In January, the Nepal government convened a five-member inquiry committee to investigate the accident. It has also ordered all domestic airlines to check their planes before they take off.
Yeti Airlines' 9N-ANC ATR-72 propeller plane took off from Kathmandu's Tribhuvan International Airport at 10:33am on Sunday for the newly inaugurated Pokhara International Airport.
At 10:50am, minutes before it was due to land, the aircraft made its final contact with air traffic control and crashed on the banks of the Seti Gandaki River in one of the deadliest accidents of the past three decades.
