Drone breaches near Dublin Airport spark regulator action

The Irish Aviation Authority (IAA) has concluded an investigation into a series of unauthorised drone operations conducted by Wills Bros Ltd. during construction activities at a site in Finglas, located south of Dublin Airport. The company operated drone flights in the Dublin Red Zone, that is within the Dublin Airport control zone. This was done without the required Operational Authorisation and without a UAS (drone) Operator Registration.

The flights were detected by the Dublin Airport Dedrone detection system. Following detection, the IAA initiated an investigation to determine the extent of the operations, the pilots involved, and the underlying causes of the non-compliance.

In line with the IAA’s safety and enforcement policy, the IAA engaged directly with Wills Bros to achieve early compliance rather than pursue legal avenues. The investigation identified three pilots working for the drone operator who, following instruction from the IAA, have since completed the appropriate training. Additionally, Wills Bros Ltd. has implemented internal procedures to ensure all future UAS operations are conducted under proper authorisation and oversight.

Enda Walsh, Manager UAS at the IAA, said:
“This case highlights the effectiveness of detection systems, but more importantly, it demonstrates what positive regulatory engagement can achieve. Wills Bros responded proactively, took full responsibility, and worked closely with our team to bring their operations into full compliance. They are now a model example of how the construction sector can safely integrate drone technology in line with aviation regulations.”

Trevor Wills, Legal Director of Wills Bros Ltd., commented:
“Once we were made aware of the issue, we immediately engaged with the IAA to understand the root causes and to implement corrective measures. The process was transparent, constructive, and ultimately strengthened our internal governance for drone operations. We appreciate the IAA’s collaborative approach and share their commitment to safe, compliant use of drone technology in the construction industry.”

Rather than focusing solely on sanctions, the IAA applied a balanced approach to prioritise learning, accountability, and the prevention of future occurrences. This approach is part of the IAA’s “Just Culture” ethos, which ensures that organisations and individuals can engage proactively with the IAA to address safety issues, while maintaining trust and collaboration across the aviation community.

The IAA continues to monitor drone activity near critical infrastructure such as airports and works with both public and private stakeholders to promote awareness, training, and safe operation under EU Regulation.

The infringements took place in GeoZone U27 (EIDW 27), the Dublin Control Zone. The area of operation was under 2km from the airport perimeter.
