A Yeti Airlines crash in Nepal that killed 72 people almost a year ago was caused by the pilots mistakenly cutting power leading to an aerodynamic stall, a report issued by a government-appointed investigation panel on Thursday said. The ATR 72, operated by privately owned Yeti Airlines, crashed just before landing in the tourist city of Pokhara on Jan. 15 in one of Nepal's worst aeroplane accidents in 30 years. There were 72 people on the twin-engine aircraft including two infants, four crew and 15 foreign nationals. It was Nepal's deadliest air crash since 1992, when a Pakistan International Airlines Airbus A300 crashed into a hillside on approach to Kathmandu, killing all 167 people on board. The European Union has banned Nepali airlines from its airspace since 2013, citing safety concerns.
