The Russian-built YAK 52 plane, which was carrying two pilots, suffered engine failure and ploughed into the house in Suoi Lau village in the central province of Khanh Hoa on Tuesday.

The pilots both walked away with minor injuries but the 69-year-old woman from the Ra Glai ethnic minority, who was preparing breakfast at the time, was killed, local police said.

Her two-year-old granddaughter was seriously injured and hospitalised.

The pilots were based at an Air Force training school in the coastal resort town of Nha Trang.

Police said authorities there were investigating the cause of the crash and would provide compensation for the victims' families.
