What happened
On 16 October 2010, a serious incident occurred at Dublin Airport involving a Boeing 737-8F2, registration TC-JGG, and an Airbus 319, registration D-AGWJ. While the Airbus was on short final approach to Runway 28, the Boeing 737, which was taxiing for departure, crossed the holding position and entered the active runway.
The crew of the arriving Airbus observed the Boeing 737 approaching the runway and initiated an immediate go-around maneuver. At the same time, Air Traffic Control issued a go-around instruction to the Airbus. Radar data showed that the aircraft came within approximately 144 feet of vertical separation and 0.4 nautical miles of horizontal separation at the closest point. There were no injuries and no damage to either aircraft.
The investigation
The AAIU examined radar data, air traffic control communications, and reports from both flight crews. The investigation focused on the taxi instructions provided by the Surface Movement Controller and the interpretation of airport signage by the Boeing 737 crew.
Investigators found that the Boeing 737 crew was performing various cockpit tasks while taxiing. The investigation also reviewed the airport's aeronautical information, specifically regarding the holding positions on Taxiway E1, which serves both Runway 28 and Runway 34.
