On 7 October 2014, a locally-based Boeing 737-800 taxiing for departure from runway 34 at Dublin as cleared in normal night visibility collided with another 737-800 stationary in a queue awaiting departure from runway 28. Whilst accepting that pilots have sole responsible for collision avoidance, the Investigation found that relevant restrictions on taxi clearances were being routinely ignored by ATC. It also noted that visual judgement of wingtip clearance beyond 10 metres was problematic and that a subsequent very similar event at Dublin involving two 737-800s of the same Operator was the subject of a separate investigation.
Description
On 7 October 2014, a Boeing 737-800 (EI-EMH) being operated by Ryanair and taxiing for departure on a scheduled passenger flight from Dublin to Edinburgh (RYR 812) was involved in a collision in normal night visibility with a stationary Boeing 737-800 (EI-EKK) also operated by Ryanair and on a scheduled passenger flight from Dublin to Charleroi (under R/T callsign RYR 65ND) and in a queue of aircraft awaiting departure from a different runway. Both aircraft sustained substantial airframe damage but there were no occupant injuries. Passengers were disembarked from both aircraft prior to further movement under tow.
Investigation
An Investigation was carried out by the Irish AAIU. Both aircraft remained in their post impact positions until further movement was authorised by the Inspector in Charge. Both the Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR) from both aircraft were removed and their data were successfully downloaded. Relevant ATC recordings, including that from the ASMGCS, were also available.
It was noted that the 40 year-old Captain of the aircraft which was stationary at the time of the collision had 7,120 total flying hours including 6,310 hours on type and that the 51 year-old Captain of the aircraft which was moving at the time of the collision had 11,000 total flying hours including 7,000 hours on type. Both Captains were familiar with operations at Dublin.
