EU Eases Airport Liquid Restrictions at Select Airports with CT Scanners

The EU lifts the 100ml liquid limit at airports with approved CT scanners, creating a fragmented but modernized security approach across Europe.

Introduction: Easing Airport Security Rules in the EU

The European Union has taken a significant step toward modernizing airport security by updating its long-standing rules on carrying liquids through checkpoints. These changes mark a potential shift in how passengers experience air travel across Europe, especially concerning the 100ml liquid restriction that has been in place since 2006. However, the implementation of these new rules has sparked confusion and inconsistency across the bloc.

As of mid-2025, only airports equipped with specific, European Civil Aviation Conference (ECAC)-approved computed tomography (CT) scanners are permitted to lift the 100ml limit. This selective application has led to a fragmented landscape where some travelers enjoy relaxed rules while others still face old restrictions. The disparity has raised operational concerns among airport authorities and left many passengers uncertain about what to expect during their journeys.

This article explores the background behind the liquid restrictions, the recent developments in EU policy, the technological and economic implications of CT scanner adoption, and the broader global context of aviation security modernization.

Background: The Origin of the 100ml Rule

The 100ml liquid restriction was introduced in 2006 following a foiled terrorist plot aimed at detonating liquid explosives on transatlantic flights. The incident, known as the 2006 transatlantic aircraft plot, involved plans to smuggle explosive components disguised as soft drinks aboard planes departing from the United Kingdom. In response, security agencies worldwide implemented strict limits on liquid volumes in carry-on luggage to mitigate similar threats.

Traditional X-ray scanners used at airport checkpoints lacked the capability to accurately detect liquid explosives, necessitating a blanket restriction on container sizes. Over time, this rule became a standard part of global aviation security protocols, despite its inconvenience for travelers.

Technological advancements eventually led to the development of CT scanners capable of producing detailed 3D images of luggage contents. These scanners can identify a wider range of threats, including liquid explosives, potentially rendering the 100ml rule obsolete. However, the path to widespread adoption has been anything but straightforward.

Temporary Reinstatement and Technical Challenges

In 2024, the EU temporarily reinstated the 100ml limit at airports using CT scanners due to concerns over scanner reliability. Reports indicated that the software used in some scanners was producing a high rate of false positives, prompting the European Commission to pause the easing of restrictions until recalibration and further testing could be conducted.

This decision mirrored similar delays in the United Kingdom, where the government extended its CT scanner deployment deadline to summer 2025. The technical setbacks highlighted the complexity of integrating new security technology into high-traffic environments and underscored the importance of rigorous validation.

Despite these challenges, the EU resumed its phased easing of the liquid rule in 2025, allowing airports with ECAC-approved scanners to lift the restriction. However, the limited scope of this approval has led to a patchwork of Regulations across member states.

Implementation and Impact: Fragmented Adoption Across Europe

Scanner Costs and Limited Manufacturer Approval

One of the primary barriers to widespread CT scanner adoption is cost. According to estimates, CT scanners are approximately eight times more expensive than traditional X-ray machines, with maintenance costs four times higher. For instance, London Heathrow Airport would require an estimated £1.04 billion to fully implement the new technology across its terminals.

Currently, only scanners produced by Smiths Detection, a UK-based manufacturer, have received ECAC approval for lifting the 100ml restriction. This exclusivity has effectively sidelined other manufacturers, such as Nuctech and Rapiscan, from participating in the EU’s modernization efforts. The reliance on a single supplier raises concerns about reduced competition and potential supply chain bottlenecks.

As a result, only a select number of airports, such as those in Rome, Milan, Berlin, Amsterdam, and Stockholm, have been able to implement the new rules. Other airports remain bound by the 100ml limit, creating inconsistencies for travelers and operational headaches for airport staff.

“Security is non-negotiable, but the EU certification system must provide legal certainty.”, Olivier Jankovec, Director General, ACI Europe

Passenger Confusion and Operational Strain

The selective application of the new rules has led to widespread confusion among passengers. Travelers departing from an airport with approved CT scanners may be allowed to carry liquids in containers up to 2 liters, only to have those items confiscated upon return to an airport still enforcing the 100ml limit.

Airports operating with CT scanners but still subject to the 100ml rule have reported decreased throughput and increased staffing needs. The mismatch between scanner capabilities and regulatory requirements undermines the efficiency gains that the technology was meant to deliver.

In response, the European Commission has emphasized the importance of clear communication. Spokesperson Anna-Kaisa Itkonen noted that while the easing of restrictions is contingent on scanner approval, airports must implement practical measures to inform travelers about the applicable rules.

Market Trends and Future Growth

The market for CT scanners is expected to grow significantly in the coming years, driven by a global push to modernize airport security infrastructure. Analysts project a compound annual growth rate (CAGR) of 9.5% for the European CT scanner market from 2024 to 2030.

This growth is fueled by the post-pandemic recovery of air travel and increasing investments in Automation and artificial intelligence for threat detection. However, the high cost of equipment and the limited number of approved manufacturers may slow adoption, particularly among smaller regional airports.

To address these challenges, some industry experts have called for broader ECAC certification of additional scanner models and financial support mechanisms to help airports upgrade their systems.

Global Context and Comparative Approaches

United Kingdom and United States Perspectives

While the EU grapples with fragmented implementation, other regions are taking different approaches. The United Kingdom, for example, has set a nationwide deadline of summer 2025 for full CT scanner deployment, albeit with delays due to technical issues similar to those faced by the EU.

In the United States, the Transportation Security Administration (TSA) is conducting pilot programs to evaluate the feasibility of easing liquid restrictions. Although no nationwide changes have been announced, the U.S. appears to be moving cautiously in the direction of modernization.

These contrasting approaches illustrate the broader global trend toward updating aviation security protocols, but they also highlight the importance of coordination and standardization to avoid confusion and inefficiencies.

Standardization and Policy Recommendations

Industry stakeholders have urged the European Commission to develop a comprehensive roadmap for lifting the 100ml restriction across all member states. Such a plan would involve accelerating the Certification process for additional scanner models and providing financial incentives for airports to make the transition.

Standardizing rules across the EU could help minimize passenger confusion and ensure a more seamless travel experience. It would also level the playing field for airports, many of which are currently penalized for being early adopters of the technology.

Without such measures, the EU risks perpetuating a fragmented system that undermines both security and efficiency.

Conclusion: Toward a Unified Security Framework

The EU’s decision to ease liquid restrictions at airports equipped with approved CT scanners represents a significant step forward in aviation security. However, the uneven implementation of these rules has created a fragmented environment that poses challenges for both travelers and airport operators.

To fully realize the benefits of modern security technology, the EU must address the current disparities by expanding scanner certification, supporting infrastructure investments, and improving communication with passengers. Doing so will help create a more consistent and efficient travel experience while maintaining the high security Standards that air travel demands.

Brazil ANAC Suspends Aircraft Certifications After Budget Freeze

Brazil’s ANAC halted all aircraft certifications and aviation exams after a federal budget freeze cut its funding by R$ 24 million.

Published

on

This article summarizes reporting by Bloomberg by Rachel Gamarski.

Brazil’s National Civil Aviation Agency (ANAC) has suspended all aircraft certification processes and aviation professional exams following a federal budget freeze, threatening to delay airline fleet expansions and exacerbate labor shortages.

The operational cuts, announced by the regulator on June 1, 2026, include an immediate 40 percent reduction in oversight and inspection activities. The reductions stem from Decree 12.990, published by the Brazilian Federal Government on May 29, 2026, which mandates an 18 percent linear reduction in the execution limits for federal agencies. Bloomberg reported on June 7, 2026, that the halt in approvals arrives just as carriers are attempting to meet high travel demand and resolve existing fleet constraints.

Impact on fleet expansion and airline operations

The suspension of aircraft certifications effectively blocks new airframes from entering the Brazilian civil aviation market. According to Bloomberg, the regulatory freeze threatens to delay the arrival of new aircraft and planned capacity expansions. Airlines operating in Brazil are currently working to address fleet shortages while managing robust passenger demand.

In an official statement, ANAC emphasized the severity of the situation.

“Without certification, there is no operation of new aircraft in the Brazilian civil aviation market.”

The budget freeze also halts exams for pilots and flight attendants. This suspension is expected to restrict the pipeline of new aviation professionals, compounding existing labor pressures within the sector. Flying clubs, maintenance workshops, and parts manufacturers are broadly affected by the reduction in regulatory services.

Broader regulatory and economic consequences

The ANAC budget reduction totals R$ 24 million and is part of a larger fiscal austerity initiative by the Brazilian government. The broader measure freezes approximately R$ 24 billion across various public administration sectors to meet 2026 fiscal targets. This includes a R$ 300 million cut distributed across Brazil’s 11 regulatory agencies.

Beyond the suspension of certifications, ANAC has been forced to dismiss outsourced workers, halt information technology investments, and cancel its participation in international forums and institutional safety events.

The Committee of Federal Regulatory Agencies (COARF) issued a statement on June 2, 2026, expressing deep concern over the budget cuts. The committee warned that the reductions threaten the legal security of investments and the regulatory stability required for economic growth, particularly as the government pursues an infrastructure concession agenda.

ANAC noted that budget freezes impacting core regulatory activities cause direct harm to society and lead to a drop in revenue, specifically citing the suspension of certification actions as a primary driver of these financial losses.

AirPro News analysis

The suspension of ANAC certification activities creates an immediate bottleneck for Brazilian operators relying on new aircraft deliveries to modernize fleets and expand route networks. Carriers such as Azul, Gol, and LATAM Airlines Brasil depend on a steady flow of regulatory approvals to induct new Airbus, Boeing, and Embraer aircraft into commercial service.

A prolonged freeze on certifications and professional exams will likely force airlines to extend the leases of older, less efficient aircraft to maintain capacity. This dynamic could increase operating costs and place upward pressure on ticket prices in a market already sensitive to fuel and currency fluctuations. The disruption to pilot and flight attendant credentialing also risks creating a medium-term staffing deficit, limiting the ability of airlines to scale operations once the budget impasse is resolved.

This is a developing story. Information may change as official details are released.

This article summarizes reporting by Agencia EFE, Primicias, and Ecuavisa.

An Iberia Airbus A350-941 sustained damage to its left winglet on June 4, 2026, after striking a fire department vehicle during a ceremonial water cannon salute at José Joaquín de Olmedo International Airport (GYE) in Guayaquil, Ecuador, forcing the cancellation of its scheduled transatlantic flight.

The incident occurred at 16:56 UTC (11:56 local time) as the widebody aircraft was preparing to operate Flight IB132 to Madrid. According to reporting by Agencia EFE and local Ecuadorian outlets, the water salute was arranged to mark a temporary equipment upgrade on the route, with the Airbus A350-900 replacing the Airbus A330-200 typically used by the Spanish flag carrier.

Ground collision during ceremonial salute

Terminal Aeroportuaria de Guayaquil S.A. (TAGSA), the airport operator, confirmed the sequence of events in an official statement. According to Primicias, TAGSA reported that during taxi, the tip of the aircraft’s wing made contact with the extension arm and turret of a fire engine belonging to the airport’s Fire Extinguishing Service (SEI).

Following the collision, the flight crew interrupted the departure sequence and returned the aircraft to the apron for a technical inspection. Agencia EFE reported that no injuries occurred among the passengers or crew. The aircraft, registered as EC-NXD, was grounded pending a full damage assessment, and passengers were subsequently rebooked on alternative flights.

Regulatory oversight and fleet implications

The Dirección General de Aviación Civil (DGAC) of Ecuador has initiated an investigation into the ground collision. The regulatory authority will examine the coordination between the flight crew, air traffic control, and the SEI personnel conducting the water arch maneuver. No official cause has been determined.

The grounding of the Airbus A350-941 disrupts Iberia’s planned capacity increase for the Guayaquil market. The aircraft swap from the Airbus A330-200 was intended to provide additional seats and cargo volume on the direct route to Spain. The airline has not yet specified how long the damaged airframe will remain out of service while repairs are evaluated and executed.

AirPro News analysis

Water cannon salutes are a long-standing aviation tradition used to celebrate inaugural flights, retiring captains, and new aircraft types. However, we note that these ceremonial events carry inherent operational risks. Positioning heavy fire apparatus near active taxiways and maneuvering large aircraft through restricted clearances requires precise coordination. While relatively rare, ground collisions during these salutes highlight the tension between marketing traditions and the strict safety margins required in commercial aviation operations. The resulting damage to a high-value asset like an Airbus A350 underscores the financial and operational exposure operators face during non-standard ground maneuvers.

NTSB Reports United Airlines Flight 169 Newark Approach Incident

NTSB preliminary report details United Airlines Flight 169 striking a light pole at Newark due to low airspeed and gusty winds during approach.

Published

on

This article is based on an official press release from the National Transportation Safety Board (NTSB).

On June 4, 2026, the National Transportation Safety Board (NTSB) released its preliminary report detailing the May 3 accident involving United Airlines Flight 169 at Newark Liberty International Airport (EWR). The incident highlights the operational challenges of landing heavy widebody aircraft during gusty conditions on constrained runways.

The Boeing 767-400ER, arriving from Venice, Italy, struck a light pole on the New Jersey Turnpike while on short final approach. According to the NTSB’s factual findings, the aircraft crossed the busy highway at an altitude of just 19 feet above the ground after its airspeed decayed during the descent.

The collision caused substantial damage to the aircraft and resulted in minor injuries to a commercial truck driver on the ground. The NTSB has officially classified the event as an accident, prompting immediate safety reviews and procedural updates from the airline.

Flight Details and the Approach

According to the NTSB preliminary report (DCA26FA194), United Airlines Flight 169 was operating from Venice Marco Polo Airport to Newark on May 3, 2026. The 23-year-old Boeing 767-424ER (registration N77066) was carrying 231 individuals, comprising 220 passengers, three flight crew members, and eight cabin crew members.

The flight proceeded normally until the descent phase. The NTSB notes that the flight crew initially planned to land on Runway 4R. However, air traffic control changed the runway assignment twice due to challenging weather conditions. Winds were reported at 19 knots and gusting up to 30 knots, leading controllers to ultimately clear the aircraft for Runway 29.

Cockpit Dynamics and Warnings

The NTSB report provides critical insight into the cockpit environment during the final moments of the flight. The captain was the pilot flying, while the first officer monitored the flight instruments.

As the aircraft descended toward the runway, its airspeed began to decay. The first officer issued verbal warnings to the captain regarding the aircraft’s energy state.

“hey you are slow… you are still slow and a little low”

According to the NTSB, the captain acknowledged hearing the “airspeed slow” callout but stated he felt the airplane remained in a safe position to continue the landing.

The Collision and Aftermath

The decaying airspeed and low glide path culminated in the aircraft crossing the New Jersey Turnpike at an altitude of just 19 feet above the ground. During this low pass, the aircraft’s landing gear and underside struck a light pole located on the highway.

The NTSB report states that the captain recalled hearing a “thump” just before touchdown, while the first officer felt a “mild jolt” as they neared the runway threshold. Despite the impact, the Boeing 767 landed safely and taxied to the gate under its own power.

Ground Impact and Injuries

Debris from the severed light pole fell onto the southbound lanes of the turnpike, striking a commercial tractor-trailer operated by Baltimore-based H&S Bakery, as well as a Jeep traveling on the highway.

While no passengers or crew members on the aircraft were harmed, the NTSB confirmed that the truck driver, Warren Boardley, sustained minor injuries from shattered glass. He was treated at a local hospital and subsequently released. The truck sustained damage to its windshield and aluminum siding.

Post-flight inspections of the Boeing 767 revealed substantial damage, including three punctures on the fuselage and slash marks on one of the landing gear tires. This damage led the NTSB to officially classify the event as an accident.

Industry Response and Safety Measures

Following the accident, United Airlines took immediate administrative and procedural actions. The airline removed the involved flight crew from service pending an internal safety review.

Furthermore, United Flight Operations issued an Operations Alert to its pilots regarding arrivals at EWR’s Runway 29. The alert emphasized the importance of relying on visual glideslope indicators (VGSI/PAPI) to ensure safe obstruction clearance. A subsequent Pilot Bulletin was also issued regarding short runway landing guidance.

AirPro News analysis

We note that Runway 29 is the shortest runway at Newark Liberty International Airport, measuring 6,725 feet. It features a displaced threshold designed specifically to provide a safety buffer from the adjacent, highly congested Interstate 95. Aircraft landing on this runway routinely pass at low altitudes over the highway.

Aviation analysts frequently point out that the Boeing 767-400ER’s extended fuselage can create visual illusions for pilots during the landing flare. Because the pilot’s eye level sits high in the cockpit while the main landing gear hangs significantly lower, precise glide path management is absolutely critical to ensure obstacle clearance. The combination of gusty winds, a late runway change, and the specific ergonomics of the 767 likely compounded the difficulty of this approach.

Frequently Asked Questions (FAQ)

Was anyone injured in the United Airlines Flight 169 accident?
No passengers or crew members on the aircraft were injured. However, a truck driver on the New Jersey Turnpike sustained minor injuries from shattered glass when debris from a struck light pole hit his vehicle.

What caused the aircraft to fly so low?
The NTSB’s preliminary report indicates that the aircraft’s airspeed decayed during a gusty approach, leading to a low glide path. The first officer warned the captain that they were “slow and a little low.” The investigation is still ongoing to determine the official probable cause.

What is the current status of the investigation?
The NTSB has released its preliminary report (DCA26FA194) and officially classified the event as an accident due to substantial aircraft damage. A final report detailing the probable cause will be released at a later date.
