Serious Incident: two Boeing 737 8AS aircraft, EI-EFF and EI-DHA, Dublin Airport, on 8 March 2015: Report 2015-022

 

On the evening of 8 March 2015, the Air Movements Controller (AMC) at Dublin Airport (EIDW) reported a loss of separation between a departing and a landing aircraft.  

 

The departing aircraft (EI-EFF, using ‘callsign 342’) was cleared for take-off with a landing aircraft (EI-DHA, using ‘callsign 45TR’) at 3.2 NM on final approach to the same runway.  Re-appraising the situation, the AMC attempted to stop the departing aircraft at the holding point, however, as a result of a blocked transmission the departing aircraft continued past the stop line which was in accordance with its previously issued clearance.  Clearing the departing aircraft for an immediate take-off, the departing aircraft became airborne prior to the arriving aircraft touching down.  

 

A runway occupation alert, a function of the Advanced Surface Movements Guidance and Control System (A-SMGCS), activated as a result of the reduced separation between the aircraft during the event.
