The first official Indonesian report on the AirAsia crash says the accident was caused by "icing" that damaged the plane's engines - a finding experts immediately doubted.
In a seemingly premature attempt to explain the crash, Indonesia's meteorological agency released a 14-page report blaming the accident on "worrying" weather conditions that froze machinery in the Airbus A320 aircraft.
"Based on data that is provided on the last location of the plane, the weather is the cause of the accident," said the report by Indonesia's Meteorology, Climatology and Geophysics Agency.
"The most probable weather phenomenon that caused the plane engines to be damaged is icing. This is only one analysis based on the meteorological data and not the final cause of the incident."
But the findings were called into question by aviation analysts, who said modern commercial aircrafts had resilient anti-icing devices.
