Responding to parliamentary questions from deputies Octavie Modert and Emile Eicher of the Christian Social People’s Party (CSV), Backes confirmed that technical assessments had largely been completed by independent experts. While final laboratory tests are pending, the results to date indicate that the problems stem from the earlier resurfacing period, rather than any new issue.
The key issue with the runway was identified as upper asphalt layers that have separated from those underneath. All of the affected surfaces were laid during the 2021–22 works. Backes said the outcome of the renovation had not met expectations and confirmed that a programme of preventive repairs and intensified inspections had been implemented.
The work was contracted under a results-based agreement, which required delivery of a functional runway free of defects. Asked whether the companies had performed the work properly, Backes said this was a matter that may, if necessary, be clarified by third parties.
The minister stated that she was informed in detail of lux-Airport’s concerns in August 2024, following earlier reports of damage. Responsibility for managing and addressing the defects lies with lux-Airport, which commissioned and oversees both the technical and construction teams.
Following a temporary runway closure on 13 June 2025, lux-Airport introduced additional overnight inspections and repairs. These are being carried out during periods when the runway is not in use, and have not affected regular flight operations. Backes insisted that passenger safety remains the highest priority, and that no compromises would be made.
A full resurfacing of the runway is not currently planned. Major works of this kind typically occur every 30 years, although the asphalt surface may require more frequent renewal due to heavy use. Experts are now assessing whether further corrective measures will be necessary in the short or medium term.
The runway’s condition has “to date” not impacted the airport’s status as a NATO facility. Backes also rejected any suggestion of a link between the runway issues and the nearby motorway slip road in Pontpierre, despite some overlap in contractors.
Emergency procedures are in place should the runway require another sudden closure. Previous repairs have been carried out quickly and with minimal disruption, the minister said. Any future measures would be implemented with sufficient lead time to avoid operational impact.
Lux-Airport has engaged external experts to continue evaluating the situation. The scope and timeline of any further work will depend on their findings.
