Sounds like someone feathered the wrong prop or grabbed the wrong lever……REPORT Yeti ATR-72 crash: data show both propellers transitioned to the feather position
The two black boxes had been read “successfully” and give first clues on what happened.
The Yeti Airline ATR-72 – reg. 9N-ANC – was carrying 68 passengers and 4 crew members when it crashed near Pokhara International Airport.
Announcing that the two black boxes had been read “successfully” in Singapore, the AIC (air accident investigation committee) clarified on February 6, 2023 that “the flight data recorder (FDR) and the Cockpit Voice Recorder (CVR) of Yeti Airlines ATR-72 indicates that an engine problem was the cause of the plane crash on January 15 in Pokhara ”.
And specifies a little further: the first analysis of the FDR indicates that “the propellers of the two engines transitioned to the feather position before the crash “. The NAIC points out, however, that the reason for this ” is still being determined, with human factors as well as technical factors being still under investigation ”.
None of the 68 passengers and 4 crew members survived: 53 Nepalese, five Indians, four Russians, two South Koreans and a Frenchman, an Irishman, an Australian and an Argentinian (including six children) were on board , the two pilots and two cabin crew members being all Nepalese.
Never flew the ATR but as the kids say this is “sus”
