On 18 June 2021, a Boeing 787-8 being operated by British Airways was being loaded for a cargo flight at Heathrow whilst line engineering carried out checks required to permit despatch with a deferred minor defect for later rectification. The check required cycling the landing gear with locking pins inserted so that only the bay doors cycled but when this was done, the nose gear retracted and the front of aircraft dropped to the ground causing significant damage to the airframe and minor injuries to two people. The nose gear downlock pin had inadvertently been inserted into the wrong hole.
