A confidential report by the Belgian public service union CGSP has exposed what it calls "major dysfunctions" in the security of Belgian airports, specifically targeting the administrative body responsible for overseeing compliance with safety rules. According to *Le Soir*, which obtained the document, these shortcomings are systemic and pose a direct risk to passenger safety. The union report describes a security system plagued by "systemic failures" and a lack of oversight from the Directorate General for Air Transport (DGTA), the authority tasked with monitoring the sector. It further claims that these issues persist despite repeated reminders from the European Commission and the International Civil Aviation Organization (ICAO). For the CGSP, this situation creates a "security black hole," where each uncorrected flaw becomes an open door for illicit interference. At the heart of the criticism is the DGTA, accused by the CGSP of no longer properly fulfilling its oversight mission. According to excerpts reported by *Le Soir*, the union denounces an authority that "no longer monitors, no longer sanctions, and ignores field alerts." The report cites negligence and even obstruction in following up on reports of dysfunctions and security audits. The CGSP also describes a "toxic" social climate within the administration, which may discourage whistleblowers and weaken the safety culture. These criticisms follow a long series of alerts, already highlighted by European reports after the 2016 attacks, which pointed to a lack of regular checks on security measures in Belgian airports. Operationally, the CGSP cites "significant defects" in passenger security, linked to flaws in the organization and supervision of security procedures. Checks are insufficient, procedures are applied unevenly, and there is a lack of rigor in verifying operators' compliance with standards. Past examples, cited in parliamentary questions or European reports, have shown that "mystery passengers" have succeeded in bypassing checks with prohibited items or fake explosives, revealing gaps in training and vigilance. In some cases, the European Commission found that explosive detection systems or other security equipment were not checked regularly enough. The CGSP report continues this theme, citing a lack of sanctions for non-compliance and insufficient supervision of private security actors at airport sites. In response, the office of the Federal Minister of Mobility states that a "corrective action plan" was adopted in February, following recent ICAO observations. ICAO reportedly found the plan broadly satisfactory regarding recommendations from an audit conducted the previous autumn. Authorities highlight the existence of a national security program and incident notification procedures intended to ensure continuous improvement of security standards. However, the CGSP's criticisms suggest a significant gap remains between the regulatory framework and the reality on the ground in Belgian airports. For the union, the priority is now to restore a culture of control and sanction to close what it considers "major" gaps in passenger protection.
