On 25 November 2019, an Airbus A330-300 being used for type conversion line training was involved in a landing tailstrike at Yangon during the trainee senior Captain’s first line training flight in benign daylight conditions. The Investigation noted that the optional tailstrike prevention system was not installed on the aircraft involved and found that the operator’s standard calls for excessive pitch during landing had not been made, that the trainee had misinterpreted the Training Captain’s pitch attitude guidance during the landing and that the Training Captain was only used to having to take over control when working with junior pilots.
