Investigations into the 21 December crash of a TransAsia Airways ATR 72-200 freighter into the Taiwan Strait are progressing following retrieval of the aircraft's flight data and cockpit voice recorders last week, south-west of Makung. The Aviation Safety Council says the outside casing of both recorders separated from the main contents, but is hopeful their data has not been lost. Bad weather has slowed recovery of the recorders and wreckage. Radar data showed the aircraft dived into the sea as it flew through rain at sub-zero temperatures. Icing is being investigated as a possible factor.
