Safety - Luxembourg

PRB monitoring

▪ ANA Lux recorded difficulties in progressing the EoSM in line with the performance plan. ANA Lux achieved the RP3 targets in four out of five Management Objectives in 2024, with Safety Risk Management missing the target on two out of three questions.

▪ Luxembourg recorded a decrease in the rate of runway incursions and a significant increase in the rate of separation minima infringements.

▪ Luxembourg should ensure that the ANSP implements, in a timely and cost-efficient manner, the necessary additional measures such as enhanced processes, improved allocation of resources, targeted training, and systematic reviews. Without such actions, the achievement of the RP4 targets could be jeopardised.

Effectiveness of Safety Management (EoSM) (KPI#1)

Four out of five EoSM components of the ANSP meet the RP3 target level with only “Safety Risk Management” component below 2024 target level. Over 2024, significant improvements were observed in “Safety Policy and Objectives”, “Safety Assurance” and “Safety Culture” enabling these areas to reach the target level D.

ANA Lux planned a gradual improvement of the SMS over RP3, achieving RP3 targets in 2023. However, in 2023 ANA Lux was still below RP3 targets in four out of five Management Objectives. ANA Lux established a corrective action plan to address specific areas requiring improvement, namely the hazard identification process and the risk monitoring mechanism, showing improvements in four out of five Management Objectives between 2023 and 2024.

The NSA has cautioned that the ANSP may not be able to reach the RP4 required maturity levels if the actions outlined in the corrective action plan are not fully implemented in 2025.

Luxembourg shows a gradually decreasing rate of RIs over RP3. After a jump in 2023, the rate fell in 2024

Since 2021, Luxembourg has recorded very high rates of SMIs at the Member State level. The rate fell in 2022 and 2023 but increased significantly in 2024, the highest during the reference period.

The ANSP has conducted a detailed review of these occurrences and identified possible common causes, which were then translated into specific recommendations. The lessons learned were discussed with air traffic controllers, who were sensitised to the underlying issues. Follow-up actions and the broader topic remain part of the ANSP’s ongoing risk assessment process, within which the effectiveness of the implemented recommendations is continuously evaluated.

Additionally, as part of national oversight activities on ATM/ANS, the NSA will give due attention to occurrence reporting and investigation during the next audit, planned for Q4/2025, to ensure appropriate follow-up at the ANSP level.

Quality of occurences reporting

The number of occurrences reported at Member State level seems consistent with the occurrences reported at the ANSP level, both for SMIs and RIs.
