A321 / B738, Dublin Ireland, 2011

Summary

On 21 May 2011, a Monarch Airlines A321 taxiing for departure at Dublin inadvertently taxied onto an active runway after failing to follow its taxi clearance. The incursion was not noticed by ATC but the crew of a Boeing 737 taking off from the same runway did see the other aircraft and initiated a very high speed rejected take off stopping 360 metres from it. The incursion occurred in a complex manoeuvring area to a crew unfamiliar with the airport at a location which was not a designated hot spot. Various mitigations against incursions at this position have since been implemented.

Description

On 21 May 2011, an Airbus A321 being operated by Monarch Airlines on a passenger flight from Dublin to Tenerife failed to follow its correctly acknowledged taxi clearance and, in normal ground visibility and daylight, inadvertently taxied onto the far end of runway 16 from which a Boeing 737-800 being operated by Ryanair on a scheduled passenger flight from Dublin to Vilnius, Lithuania was taking off. The 737 crew saw the incursion and initiated a high speed rejected take of coming to a stop before reaching the other aircraft.

Investigation

An Investigation was carried out by the Irish AAIU with the relevant data available from both FDRs but only the 737 Cockpit Voice Recorder (CVR) since the A321 had departed immediately after the incursion and the relevant recording had therefore been overwritten.
