On 16 July 2016, an Airbus A321s unstabilised approach at Fuerteventura during pilot line training was not discontinued and takeover of control and commencement of a go-around had occurred just before a very hard runway contact. The subsequent landing was successful but serious damage to the main landing gear was not rectified before the next flight. The Investigation found that the hard touchdown had been recorded as in excess of 3.3g and that the return flight had been risky and unsafe after failure of the Captain and maintenance personnel at the Operator to recognise the seriousness of the hard landing.
