Collision during taxi. On 21 April, 2008 an Avro RJ85 aircraft was parked on Stand 10 at London City Airport, with an Avro RJ100 parked to its left, on the adjacent Stand 11. Prior to taxiing, the RJ85 had been repositioned by a tug to gain sufficient wingtip clearance from the RJ100. This had the effect of reducing the tail clearance between the two aircraft, which was not identified. As the RJ85 taxied forward and to the right, its tail contacted the tail of the RJ100, causing minor damage to the RJ100™s right elevator.
