Lao Airlines Flight 301 was a scheduled domestic passenger flight from Vientiane to Pakse, Laos. On 16 October 2013, the ATR 72–600 aircraft operating the flight crashed into the Mekong River in Pakse, killing all 49 people on board. The accident, the first involving an ATR 72–600, was the deadliest ever to occur on Laotian soil and the third-deadliest involving an ATR 72 behind Aero Caribbean Flight 883 and American Eagle Flight 4184 which both killed 68. It was also the first fatal accident for Lao Airlines since 2000.[2][3][4][5]
