On 28 April 2017, a Boeing 777-300 made a 3.2g manual landing at Hong Kong during a Final Line Check flight for a trainee Captain which was not assessed as such by the crew and only discovered during routine flight data analysis. The Investigation noted that the landing technique used was one of the reasons the Check was failed. The trainee had been an experienced 737 Captain with the operator who had returned from 777 type conversion training with another airline and was required to undertake line training to validate his command status in accordance with local requirements.
