On 10 July 2021, an Airbus A320 rejected takeoff from Heraklion, Greece, after rotation, and although the nose landing gear was allowed to drop heavily, this was not reported by the crew. All wheels were replaced and after the aircraft was released to service, the same crew positioned the aircraft to Dusseldorf, Germany, and a new crew took over for a round trip to Kavala, Greece. After departing Kavala, the landing gear could not be retracted and a L/G SHOCK ABSORBER FAULT was annunciated. A MAYDAY return-to-land followed, and severe structural damage caused by a fully deflated nose shock absorber was then found.
