Near Miss at Nice Airport Highlights Runway Safety Challenges
A Nouvelair A320 flew 10 feet over an easyJet plane at Nice Airport, prompting BEA investigation and safety procedure revisions.
Anatomy of a Near-Miss: The Nice Airport Runway Incident
On the evening of September 21, 2025, the world of commercial aviation came within a few feet of a major catastrophe. At Nice Côte d’Azur Airport in France, a Nouvelair Airbus A320, arriving from Tunis, nearly collided with an easyJet Airbus A320 preparing for departure. The incident involved a runway confusion that led to the inbound aircraft flying directly over the stationary plane with a vertical separation that shrank to a mere 10 feet. With a combined total of 346 passengers and crew members on board the two aircraft, the event has become a critical case study for aviation safety regulators.
The French Bureau d’Enquêtes et d’Analyses (BEA), the agency responsible for investigating aviation accidents and incidents, immediately launched a full-scale inquiry. Their preliminary report has provided a chilling, second-by-second account of the event, shedding light on a chain of contributing factors rather than a single point of failure. Such near-misses, while rare, are invaluable learning opportunities. They force us to re-examine airport procedures, technological reliances, and the complex interplay of human factors that define modern air travel. Understanding what went wrong is the only way to ensure it doesn’t happen again.
This incident wasn’t just a close call; it was a stark reminder of the razor-thin margins that keep our skies safe. The preliminary findings point towards a confluence of issues, including significant disparities in runway lighting, deteriorating weather conditions, and the unavailability of key navigational aids. As we break down the sequence of events and the factors at play, we gain a clearer picture of the challenges faced by flight crews and air traffic controllers in high-pressure environments.
A Breakdown of the Incident
The events of that night unfolded rapidly, turning a routine arrival and departure into a serious incident. The two aircraft involved were Nouvelair flight TS-INP, an Airbus A320 carrying 176 passengers and 8 crew from Tunis, and easyJet flight OE-IJZ, also an Airbus A320, with 170 passengers and 8 crew members, preparing to depart for Nantes. The incident occurred around 21:30 local time, under the cover of darkness and in worsening weather.
The Approach and Runway Confusion
The flight plan for the Nouvelair A320 was straightforward. Air Traffic Control (ATC) had cleared the crew to land on runway 04L. The crew correctly read back this instruction multiple times, confirming their clearance. However, their aircraft did not align with runway 04L. Instead, it lined up for an approach to the parallel runway, 04R, where the easyJet aircraft was holding its position, awaiting clearance for takeoff.
This critical error in alignment went uncorrected as the aircraft continued its descent. The easyJet crew, positioned on runway 04R, reportedly noticed the approaching aircraft’s lights but did not immediately recognize the imminent conflict. The situation escalated in a matter of seconds as the Nouvelair A320 descended directly towards the occupied runway, completely unaware of the aircraft sitting on the tarmac below.
The climax of the incident was the overflight itself. The BEA’s preliminary data revealed that the radio altitude of the Nouvelair A320 dropped from 39 feet to just 10 feet as it passed over the easyJet A320’s fuselage and tail. This is an incredibly small margin, representing a near-collision of the most serious kind. The Nouvelair crew, likely realizing their error at the last moment, initiated a go-around, but only after having already flown directly over the other plane.
The Role of Air Traffic Control
In the control tower, the situation was also developing at a pace that challenged human and automated systems. The tower controller had issued the correct landing clearance for runway 04L and had no reason to believe the Nouvelair crew was not complying. However, the airport was equipped with an automated runway incursion alert system, which did its job.
This system triggered an alarm in the control tower 42 seconds before the Nouvelair aircraft flew over the easyJet plane, indicating a potential conflict. Despite this advance warning, the controller’s intervention came critically late. A go-around command was issued to the Nouvelair crew, but it was transmitted two seconds after the overflight had already occurred. This highlights the speed at which a runway confusion incident can devolve into a near-catastrophe, sometimes outpacing the reaction time of even highly trained personnel.
Investigating the ‘Why’: Contributing Factors
The BEA’s preliminary report moves beyond the “what” to explore the “why.” The investigation is focused on understanding the conditions and circumstances that could lead a professional flight crew to make such a critical navigational error. The findings suggest that this was not a simple case of pilot error but rather the result of several latent conditions creating a trap for the flight crew.
Environmental and Technical Challenges
The weather on the night of September 21 was a significant factor. The crews were operating in moderate rain showers with reduced visibility. To navigate around convective clouds, the Nouvelair crew had requested a shortened approach, known as an RNP A 04L procedure. This non-standard approach, while safe, would have increased the crew’s workload during a critical phase of flight.
A crucial piece of the puzzle, as highlighted by the BEA, is the stark difference in the lighting systems for the two parallel runways. Runway 04R, the takeoff runway that the Nouvelair plane mistakenly approached, was equipped with modern, “much brighter” LED bulbs. In contrast, the correct landing runway, 04L, used older, dimmer halogen bulbs. In low visibility conditions, this disparity could create a powerful visual illusion, drawing the pilots’ attention towards the brighter, more conspicuous runway.
The BEA report notes that the lights for runway 04R (take-off runway) are “much brighter” than those for runway 04L (landing runway).
Compounding these issues was the status of the navigational aids for runway 04L. The Instrument Landing System (ILS) glideslope, which provides vertical guidance for an automated landing, was out of service. This information had been published in a NOTAM (Notice to Airmen), so the crew was aware of it. However, its unavailability meant a fully automated instrument landing was not possible, forcing the crew to rely more heavily on visual cues, cues that may have been misleading due to the lighting disparity and poor weather.
Human Factors and Procedural Questions
While technical and environmental factors set the stage, human factors are central to understanding the crew’s actions. Despite correctly acknowledging the clearance for runway 04L, the Nouvelair crew proceeded to align with 04R. This type of error can be linked to cognitive phenomena such as confirmation bias, where individuals unconsciously look for cues that confirm their existing mental model, even if that model is incorrect. The brighter lights of 04R may have created a powerful initial impression that was difficult to overcome.
The incident also raises broader questions about airport procedures. The use of a specific type of visual approach, known as a VPT-type, at night and in deteriorating weather at an airport with closely spaced parallel runways is now under scrutiny. These procedures demand a high level of situational awareness from flight crews, and the combination of factors on this particular night may have overloaded the crew’s cognitive capacity.
In response to the gravity of the incident, the French Air Navigation Service Provider (DSNA) has already taken action. It has suspended the use of this specific visual approach procedure at night when both parallel runways are in use. This immediate safety measure is designed to prevent a recurrence while the BEA continues its in-depth investigation to formulate long-term recommendations.
Aftermath and Future Implications for Aviation Safety
The near-miss at Nice Airport serves as a powerful reminder that aviation safety is a continuously evolving process. The key takeaways from the preliminary report highlight a dangerous alignment of factors: a runway confusion likely induced by a significant lighting disparity, complicated by poor weather, a non-standard approach, and the unavailability of a key navigational aid. The fact that two modern airliners came within 10 feet of each other underscores the importance of investigating not just accidents, but serious incidents as well.
The ongoing BEA investigation will be critical. The final report will analyze flight data recorders, cockpit voice recorders, and further testimony to provide a complete picture and issue formal safety recommendations. These recommendations will likely address runway lighting standards, procedures for visual approaches at night in complex airspace, and air traffic control protocols. The lessons learned from this chilling event over the French Riviera will undoubtedly influence aviation practices globally, reinforcing the systems and procedures that keep millions of passengers safe every day.
FAQ
Question: What was the closest distance between the two aircraft?
Answer: According to the preliminary report from the French BEA, the Nouvelair A320 flew over the easyJet A320 with a vertical separation that dropped from 39 feet to as low as 10 feet.
Question: Why did the Nouvelair pilots approach the wrong runway?
Answer: The full investigation is still ongoing. However, the BEA’s preliminary findings point to several contributing factors, including a significant disparity in the brightness of the two parallel runways, deteriorating weather conditions, and the unavailability of the ILS glideslope for the correct runway, which increased reliance on visual cues.
Question: What immediate safety actions have been taken since the incident?
Answer: The French Air Navigation Service Provider (DSNA) has suspended the use of the specific type of visual approach (VPT-type) that was in use during the incident. This suspension applies at night when both parallel runways at Nice Airport are active.

FAA Draft Vertiport Design Standards Remove Weight and Size Limits
FAA releases Draft AC 150/5390-4, a performance-based vertiport framework removing weight and size limits for AAM aircraft.
The Federal Aviation Administration (FAA) has published a unified, performance-based draft regulatory framework for vertical flight infrastructure, removing previous weight and size restrictions to accommodate the incoming generation of Advanced Air Mobility (AAM) aircraft.
Released on October 22, 2026, Draft Advisory Circular 150/5390-4 consolidates and replaces existing heliport and interim vertiport guidance. According to the FAA press release, the 140-page document establishes new safety margins for downwash and outwash and sizes facilities based on specific aircraft dimensions, providing the regulatory clarity required for developers to secure federal infrastructure funding.
Technical shifts in the new draft
The new draft introduces specific geometric and operational standards tailored to powered-lift aircraft, which often possess different flight characteristics than traditional rotorcraft. Among the key technical updates, the draft sets a maximum approach surface slope of 15:1 for powered-lift aircraft. This is significantly shallower than the 8:1 slope standard traditionally applied to Helicopters.
To address the aerodynamic impacts of electric Vertical Takeoff and Landing (eVTOL) designs, the FAA has established a 34.5 mph rotor wash speed threshold. Exceeding this limit triggers a requirement for downwash and outwash caution area markings to protect nearby personnel and property. Additionally, the draft mandates a 10-foot (3-meter) safety margin beyond the aircraft’s rotor diameter to determine the minimum touchdown and liftoff area (TLOF).
“The next generation of aircraft is here, and we are ensuring we have the infrastructure built to support safe takeoffs and landings for them across the National Airspace System,” FAA Administrator Bryan Bedford said in the agency’s announcement.
Replacing interim vertiport guidance
Once finalized, Draft Advisory Circular 150/5390-4 will cancel two existing documents: Advisory Circular 150/5390-2D for heliport design, issued in January 2023, and Engineering Brief 105A for vertiport design, issued in December 2024.
Engineering Brief 105A served as a stopgap measure for early vertiport planning but applied strict limitations. It only covered aircraft with a maximum takeoff weight of 12,500 pounds and a wingspan of 50 feet or less. The new draft lifts these caps entirely. Instead of relying on fixed weight and size categories, the updated framework requires facility designers to size infrastructure around the specific dimensions and performance data of the aircraft intended to use it.
The FAA will host a virtual Industry Day on November 10, 2026, to brief stakeholders on the proposed changes. The public comment period remains open until January 11, 2027, and the agency expects to publish the final design standards in the summer of 2027.
Momentum in the Advanced Air Mobility sector
The infrastructure standards arrive as the AAM sector moves closer to commercialization. The FAA has been gathering real-world operational data through its eVTOL Integration Pilot Program (eIPP), which currently oversees eight projects across 26 states. Recent eIPP milestones include a demonstration flight by BETA Technologies and United Therapeutics transporting a genetically modified pig heart, as well as an automated Cargo aircraft flight conducted by Elroy Air in Louisiana.
Regulatory momentum for the aircraft themselves is also accelerating. On October 21, 2026, U.S. Transportation Secretary Sean P. Duffy announced the issuance of the first Special Airworthiness Market Survey Certificate for an eVTOL aircraft.
Bedford noted the broader economic implications of the sector, stating that the aircraft “have tremendous potential to generate new jobs, connect communities, and strengthen American leadership in aviation.”
AirPro News analysis
The lack of finalized infrastructure standards has been a primary bottleneck for the AAM sector. While aircraft certification programs dominate industry attention, commercial eVTOL operations cannot scale without standardized, FAA-approved vertiports. By shifting to a performance-based model rather than rigid weight categories, the FAA is future-proofing the National Airspace System against rapid design iterations in the powered-lift space.
Crucially, while an Advisory Circular is not a binding regulation in itself, adherence to its standards is mandatory for projects seeking federal airport grants and Passenger Facility Charge (PFC) funding. Finalizing this document in 2027 will unlock federal capital for vertiport construction, shifting AAM infrastructure development from purely private venture funding into the realm of traditional municipal finance.

FAA Launches MedGuide Medication Database for Aviators
The FAA launched MedGuide on Oct. 1, 2026, giving pilots and air traffic controllers an official tool to verify medication compliance.
The Federal Aviation Administration (FAA) launched an interactive online database on October 1, 2026, designed to help pilots and air traffic controllers determine whether specific prescription and over-the-counter medications are acceptable for flight duties.
Dubbed MedGuide, the platform addresses a longstanding information gap that previously required aviators to consult scattered third-party lists or contact Aviation Medical Examiners (AMEs) directly to verify medication compliance. The official release arrives as the agency faces mounting congressional pressure to modernize its aeromedical clearance processes and improve transparency for aviation professionals.
Navigating the new medication database
The initial release of the tool, designated as Version 1.0, intentionally includes only medications that the FAA categorizes as allowed for use during flight or safety-related duties. Users can search for specific pharmacological treatments to verify their compliance status and review any associated operational restrictions.
A core component of the new guidance is the formalization of wait periods. The FAA established a standard minimum wait time required before an aviator can return to the flight deck or radar screen after beginning a new treatment regimen.
“When starting a new medication, in most cases, a 48-hour wait time is required before returning to safety-related duties. This period allows the medication to take effect and ensures no aeromedically significant side effects develop,” the FAA stated in its official MedGuide documentation.
The agency explicitly noted that the presence of a medication on the allowed list does not automatically clear an aviator to fly. The underlying medical condition being treated must also be evaluated for clinical stability. The FAA stressed that the online tool is not intended to replace an individualized assessment by a certified AME.
Industry response to aeromedical transparency
Prior to the launch of MedGuide, pilots and air traffic controllers lacked a centralized, official, and public-facing database to check medication compliance. Aviators frequently had to rely on advisory services provided by industry associations or direct consultations with medical professionals. This fragmented approach often created uncertainty and administrative delays when aviators attempted to verify their medical status before applying for or renewing a medical certificate.
The National Business Aviation Association (NBAA) welcomed the new platform, noting that it provides the definitive guidance flight crews have long requested.
“Pilots are accustomed to clear, if-then directions, and MedGuide offers a more direct way to understand both prescription and over-the-counter medications, including any wait time after an initial or subsequent dose,” said Mark Larsen, Director of Safety and Flight Operations for the NBAA.
Larsen added that the tool equips aviators to make safe, fit-for-flight decisions about medication use, calling the database a significant step in the right direction for the industry.
Legislative mandates and rulemaking origins
The development of MedGuide by the FAA Office of Aerospace Medicine (AAM) stems directly from industry feedback and formal regulatory review. The AAM is responsible for the medical certification of all U.S. civil airmen and the medical clearance of air traffic control specialists, overseeing the national network of AMEs.
On April 1, 2024, the Mental Health and Aviation Medical Clearances Aviation Rulemaking Committee (ARC) issued a report to the FAA containing 24 specific recommendations. The committee identified a critical need for accessible, transparent medical information, which spurred the creation of the MedGuide platform.
The October 1, 2026, launch also coincides with significant legislative action in Washington. On September 24, 2026, the U.S. Senate passed the Aviation Medication Transparency Act of 2026 (S. 3258). The bipartisan bill requires the FAA to publicly list medications that aviation professionals can safely use, as well as those they should avoid, along with specific wait times.
On the same day, the Senate passed the John A. Hauser Mental Health in Aviation Act (S. 3257), which mandates the FAA to update mental health guidance and improve the efficiency of the Special Issuance Medical Certification process. Both bills are currently pending in the U.S. House of Representatives.
Over the next several months, the FAA plans to expand the MedGuide database in subsequent releases. Future iterations will include conditionally acceptable medications, prohibited medications, and guidance on additional underlying medical conditions.
AirPro News analysis
We view the launch of MedGuide as a necessary operational shift for the FAA Office of Aerospace Medicine. By publishing an official, public-facing database, the regulator is moving away from a historically opaque clearance process that often generated anxiety among aviators seeking routine medical care. The timing of Version 1.0 is highly strategic. Releasing the tool just days after the Senate passed S. 3258 allows the FAA to demonstrate proactive compliance with the core requirements of the legislation before it potentially becomes law.
Offloading routine medication queries to an automated, self-service system should incrementally reduce the administrative burden on Aviation Medical Examiners. By empowering pilots to independently verify the status of common over-the-counter and prescription drugs, AMEs and the AAM can theoretically redirect their resources toward processing the persistent backlog of complex Special Issuance cases.

FAA Proposes Torque Inspection AD for 980 Airbus Helicopters
FAA NPRM targets AS350, AS355, and EC130 helicopters over a nut retainer coating flaw that risks main rotor servo-control disconnection.
This is original reporting and analysis by AirPro News.
The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) mandating torque inspections on the main rotor servo-controls of 980 Airbus Helicopters AS350, AS355, and EC130 aircraft registered in the United States.
Published as a Notice of Proposed Rulemaking (NPRM) on October 19, 2026, the regulatory action addresses a mechanical vulnerability where paint or protective coating on a nut retainer can cause a loss of tightening torque. If left undetected, the FAA warns this condition could lead to the disconnection of the upper ball bearing end from the main rotor (MR) servo-control. Such a failure would result in a complete loss of helicopter control.
Inspection requirements and compliance timelines
The proposed directive targets specific members of the Airbus Helicopters Ecureuil family. The affected models include the AS350B3, AS355F, AS355F1, AS355F2, AS355N, AS355NP, EC130B4, and EC130T2 helicopters. Under the FAA proposal, operators must perform an initial inspection of the nut tightening torque on the upper ball bearing end of all MR servo-controls within 165 flight hours or six months, whichever occurs first.
The NPRM also outlines strict requirements for follow-up inspections to ensure ongoing safety. Any time an MR servo-control featuring an affected part is installed or reinstalled on an aircraft, maintenance personnel must conduct a subsequent torque check. This secondary inspection must take place between two and 10 flight hours after the installation is complete.
The FAA is accepting public comments on the NPRM through December 3, 2026. Following the closure of the comment period, the agency is expected to review industry feedback and issue a final rule mandating the inspections. The current regulatory action is classified as an interim measure. Airbus Helicopters is actively developing a permanent design change to the nut retainer that will eliminate the problematic paint or protective coating entirely, which will likely prompt further regulatory updates once certified.
Tracing the servo-control vulnerability
The engineering investigation that led to the current NPRM originated with a different Airbus Helicopters product line. In 2024, the European Union Aviation Safety Agency (EASA) received reports of two separate instances where torque was lost between the upper ball bearing end and the MR servo-control on Dauphin and EC155 helicopters. In one of those documented cases, the components completely disconnected in flight.
That discovery prompted EASA to issue an AD for the Dauphin family on June 6, 2024. The FAA subsequently mirrored that action with its own directive for U.S.-registered Dauphin helicopters on July 10, 2025. Following those initial reports, Airbus Helicopters launched a broader engineering analysis to determine the root cause of the torque loss. The manufacturer concluded that the presence of paint or protective coating on the lock washer and nut retainer compromised the friction required to maintain proper tightening torque over time.
During this investigation, the manufacturer determined that the AS350, AS355, and EC130 families share this exact design vulnerability in their main rotor flight control systems. In response to these findings, Airbus Helicopters issued Alert Service Bulletins on April 1, 2026, mandating torque checks across the affected Ecureuil fleet. EASA followed up by issuing AD 2026-0132 on July 8, 2026, to mandate the inspections for European operators. The FAA publication of the NPRM on October 19, 2026, aligns U.S. regulations with the European mandates.
Market context and fleet impact
The Airbus Helicopters Ecureuil family, currently marketed under the H125 and H130 designations, represents one of the most successful light utility helicopter programs in aviation history. Airbus Helicopters has delivered more than 7,200 Ecureuil family aircraft worldwide.
The large number of affected U.S. aircraft reflects the heavy utilization of the type across the country. The AS350 and EC130 platforms are heavily utilized across the aviation industry for critical missions, including law enforcement, emergency medical services, aerial firefighting, powerline maintenance, and passenger transport. The 980 helicopters of U.S. registry represent a significant portion of the active domestic rotorcraft fleet.
AirPro News analysis
The sheer volume of U.S.-registered aircraft affected by this NPRM highlights the industry reliance on the AS350 and EC130 platforms. With 980 airframes requiring initial and recurring torque checks, maintenance providers and fleet operators will need to carefully schedule these inspections to avoid grounding critical public service assets. Because the FAA 165-hour compliance window is relatively short for high-utilization operators like air medical and police units, we expect a rapid mobilization of maintenance personnel once the final rule is published. The recurring inspection requirement for newly installed parts will also add a layer of logistical complexity for maintenance, repair, and overhaul facilities until Airbus Helicopters can field its permanent hardware redesign.
