Taiwan's aviation authorities have concluded that a plane crash that killed 48 people was due to pilot error and a failure within the airline to follow safety procedures.

The TransAsia Airways plane crashed on July 23, 2014, in stormy weather trailing a typhoon, killing 44 passengers and four crew members. Ten passengers survived.

Taiwan's Aviation Safety Council said in a report Friday that the crew on Flight GE222 did not realize they were too close to the ground while landing on the island of Penghu and repeatedly failed to follow standard operating procedures during the flight.

It said the captain flew the aircraft too low without having first made visual contact with the runway, likely because he was overconfident of his flying skills.
