NTSB Urges FAA Action on Bombardier Learjet Landing Gear Flaw
After a fatal 2025 crash, NTSB calls for FAA to mandate inspections and fix maintenance for Bombardier Learjet landing gear safety.

NTSB Calls for Urgent Action on Learjet Landing Gear After Fatal Accident
The National Transportation Safety Board (NTSB) has issued an urgent safety recommendation to the Federal Aviation Administration (FAA) concerning a critical flaw in the landing gear assembly of certain Bombardier Learjet models. This decisive action follows a comprehensive investigation into a fatal runway excursion in Scottsdale, Arizona, which highlighted a latent but severe safety risk. An urgent recommendation from the NTSB signifies a critical threat to life or property that requires immediate attention, compelling recipients to respond within 30 days. The gravity of the situation is underscored by the sheer number of aircraft involved, a total of 1,883 airplanes across 10 specific Learjet models currently in service.
The catalyst for this recommendation was a tragic accident on February 10, 2025, where a Learjet 35A experienced a catastrophic failure during its landing sequence. The aircraft’s left main landing gear separated upon touchdown, causing the jet to veer off the runway and collide with a parked aircraft. The incident resulted in the death of the captain and serious injuries to three other individuals. However, the NTSB’s investigation revealed that this was not an isolated event. A pattern of similar failures dating back decades pointed to a systemic issue with the landing gear’s design or, more specifically, its maintenance procedures. This history of incidents, combined with the fatal outcome in Scottsdale, has created a clear and present need for regulatory intervention to prevent future occurrences.
At the heart of the issue is a subtle but dangerous flaw in how the main landing gear is secured to the airframe. The investigation pinpointed a specific component, the aft trunnion pin and its retaining bolt, as the point of failure. The NTSB’s findings indicate that the current maintenance procedures allow for a critical misassembly that is nearly impossible to detect through standard pre-flight or even routine maintenance checks. This hidden vulnerability means that hundreds of aircraft could potentially be operating with insecurely attached landing gear, posing a significant and unacceptable risk to crew, passengers, and individuals on the ground.
Anatomy of a Failure: The Scottsdale Incident and a Hidden Flaw
The events of February 10, 2025, at Scottsdale Airport serve as a stark illustration of the potential consequences of this mechanical vulnerability. During the landing rollout, the Learjet 35A’s left main landing gear detached from the aircraft. This structural failure caused the jet to enter a “left-wing-low attitude” and veer uncontrollably off the runway. The excursion ended when the Learjet struck a parked Gulfstream G200 jet, resulting in significant damage to both aircraft. The separated landing gear was later found on an adjacent taxiway.
The human cost of this mechanical failure was severe. The captain of the Learjet was killed in the accident. The first officer and a passenger aboard the Learjet, as well as an occupant of the parked Gulfstream, all sustained serious injuries. Such outcomes transform a technical investigation into a pressing human safety issue, driving the urgency behind the NTSB’s recommendations. The investigation focused immediately on the separated landing gear, seeking to understand the precise cause of the detachment during what should have been a routine landing.
The Technical Flaw: A Bolt That Deceives
The NTSB’s investigation zeroed in on the aft landing gear trunnion pin and its retaining bolt. This assembly is a critical connection point that secures the entire landing gear structure to the aircraft’s wing. The board discovered that it is possible for a mechanic to inadvertently install the retaining bolt without it properly passing through the trunnion pin. In this state, the bolt appears to be correctly installed and secured, but it is not actually locking the pin in place. This leaves the landing gear insecurely attached to the airframe, held on by little more than friction and positioning.
This misassembly is particularly dangerous because it is not readily detectable. A visual inspection during a pre-flight walk-around would not reveal the improperly seated bolt. Furthermore, even during subsequent maintenance, the error can be easily missed without a specific verification step. This creates a latent failure condition that can persist through numerous flight cycles, waiting for the stresses of a landing to trigger a catastrophic separation. The NTSB’s findings highlight a critical gap in the maintenance process that has allowed this risk to go unaddressed.
In the absence of a required verification step, a mechanic could inadvertently install the retaining bolt without it passing through the trunnion pin, leaving the gear insecurely attached to the airframe. The misassembly is not readily detectable during routine maintenance or preflight inspections.
A Pattern of Failures and a Call for Mandatory Action
While the Scottsdale accident was the immediate trigger, the NTSB’s investigation quickly uncovered a disturbing history of similar incidents. This pattern demonstrates that the vulnerability in the Learjet’s landing gear assembly is a long-standing issue, not a new phenomenon. By looking into past events, the board identified at least three prior occurrences where a Learjet’s main landing gear disconnected from the airframe due to the same failure of the retaining bolt and trunnion pin assembly.
These historical cases span several years and different aircraft models within the Learjet family. On October 4, 1995, a Learjet 25B experienced a left main landing gear collapse in Oklahoma City. A few years later, on February 4, 2001, another Learjet 25B suffered a gear separation after touchdown in Fort Pierce, Florida. A third documented incident occurred on March 28, 2008, when a Learjet VU-35A operated by the Brazilian Air Force had its left main landing gear collapse in Recife, Brazil. This documented history proves that the potential for misassembly has existed for decades, making the need for a permanent solution all the more critical.
The NTSB’s Two-Pronged Recommendation
In response to its findings, the NTSB has issued two specific recommendations. The first and most urgent is for the FAA to mandate compliance with service bulletins issued by Bombardier. Following the Scottsdale accident, Bombardier released a service bulletin requesting a one-time inspection of the landing gear on all affected models. However, the response has been alarmingly low; according to Bombardier, only 12 percent of the 1,883 airplanes have been inspected. By calling for an FAA mandate, likely in the form of an Airworthiness Directive (AD), the NTSB is seeking to make these inspections compulsory, ensuring the entire fleet is checked.
The second recommendation targets the root cause of the problem: the maintenance procedure itself. The NTSB has asked the FAA to require Bombardier to revise its procedures to include a specific post-maintenance visual check. This new step would require mechanics to visually verify the correct position of the aft trunnion pin and retaining bolt after installation, eliminating the ambiguity that allows for the current misassembly. This procedural fix is designed to prevent the error from occurring in the first place, providing a long-term solution to the safety vulnerability.
Conclusion: From Investigation to Prevention
The NTSB’s urgent recommendations regarding the Bombardier Learjet fleet represent a critical step in the aviation safety cycle. The investigation into the tragic Scottsdale accident successfully identified not only a mechanical point of failure but also a procedural gap that allowed a hidden danger to persist across more than 1,800 aircraft. By uncovering a history of similar incidents, the board has demonstrated a systemic risk that requires a robust and mandatory solution. The focus now shifts to the FAA and Bombardier to implement these changes swiftly.
This case serves as a powerful reminder that aviation safety is an ongoing process of learning and adaptation. The subtle, hard-to-detect nature of the landing gear flaw underscores the importance of designing maintenance procedures that are not only effective but also include clear verification steps to prevent human error. The implementation of a mandatory inspection and a revised maintenance protocol will be crucial in ensuring that this specific type of accident does not happen again, protecting flight crews, passengers, and the public from a known and preventable risk.
FAQ
Question: What is the specific problem with the Learjet landing gear?
Answer: The NTSB found that the retaining bolt for the aft trunnion pin on the main landing gear can be installed incorrectly without being obvious. This leaves the gear insecurely attached to the airframe, creating a risk of it separating during landing.
Question: How many aircraft are affected by this recommendation?
Answer: The recommendation affects 1,883 airplanes currently in service across 10 different Private-Jets models.
Question: Why is the NTSB’s recommendation considered “urgent”?
Answer: The NTSB issues urgent recommendations to address immediate and critical safety issues that pose a threat to lives or property. Given the fatal accident in Scottsdale and the large number of potentially affected aircraft, the agency determined that immediate action was necessary.

Schiphol Airport Traffic Decree Takes Effect With 478,000 Flight Cap
Schiphol’s new Airport Traffic Decree took effect November 1, 2026, capping flights at 478,000 a year and ending a tolerance arrangement.

A new Airport Traffic Decree (Luchthavenverkeerbesluit, LVB) for Amsterdam Airport Schiphol (AMS) entered into force on November 1, 2026, capping traffic at 478,000 flight movements a year, including a maximum of 27,000 at night, and ending a tolerance arrangement under which the old decree’s rules had not been enforced since 2015.
Schiphol announced the change in a press release dated November 1, 2026, calling it a significant moment for the airport, airlines and local residents and saying the decree brings long-awaited clarity on noise, safety, emissions, runway use and the number of flights. For operators, the detail that matters most is in the Dutch government’s announcement of October 27, 2026: the 478,000 cap holds until a noise target is met, and any growth toward 500,000 movements depends on noise falling further, with both chambers of parliament involved in that decision.
What the decree sets
According to Schiphol, the 478,000 cap means fewer flights than before the coronavirus crisis, when the airport handled around 500,000 flights a year, including approximately 32,000 at night. The decree sets noise rules that protect residents across a larger area than before. Its enforcement thresholds allow for annual variation from factors such as weather and runway usage, but Schiphol said that leeway cannot be used to add flights.
The government said the decree contains 148 enforcement points, compared with 35 in the old decree, each setting a maximum annual noise level at a location around the airport. If a limit threatens to be exceeded, Schiphol must intervene. If a limit is exceeded, the Human Environment and Transport Inspectorate (Inspectie Leefomgeving en Transport, ILT) can enforce.
That enforcement has a gap for now. During the Senate’s review of the decree on September 28 and 29, 2026, Minister of Infrastructure and Water Management Vincent Karremans said the inspectorate cannot yet impose an administrative fine when a noise limit is exceeded, and promised to propose an amendment to the Aviation Act (Wet luchtvaart) to make that possible, according to the Senate’s summary.
The decree includes targets to cut noise nuisance by 20 percent during the day and 15 percent at night. The House of Representatives’ summary of its September 29 debate describes the cabinet’s aim as 20% fewer people experiencing serious noise nuisance during the day and 15% fewer at night, compared with 2024. The Balanced Approach that the ministry introduced in 2024, which combines a rising share of quieter aircraft with higher charges for noisier aircraft through differentiated airport charges, is now legally embedded in the decree. Schiphol said more than 40 percent of aircraft at the airport now belong to the newest and quietest categories.
Schiphol chief executive Pieter van Oord called the decree an important milestone. “As an international hub, Schiphol is of great value to the Netherlands,” he said.
“After years of uncertainty, the LVB provides us with a legal foundation. A foundation on which we can build an airport that is future-proof and increasingly quiet, and that continues to fulfil its role for the Netherlands,” van Oord said.
A tolerance arrangement, a court ruling and a new decree
Since 2015, Schiphol has operated under a tolerance arrangement (gedoogsituatie). The government said the rules of the old decree were no longer enforced because all parties had agreed on other approaches to flight operations, but the new rules were never formally established, so residents could not invoke them. The decree that took effect on November 1 ends that situation, the government said.
The new decree follows a court ruling that struck down an earlier version of the same cap. On March 11, 2026, the Administrative Jurisdiction Division of the Council of State (Raad van State) annulled an earlier amendment that had capped Schiphol at 478,000 flights a year from November 1, 2025. According to a summary of the ruling (ECLI:NL:RVS:2026:1400) published by legal publisher PONT Omgeving, the court found that the minister had given insufficient reason for treating a maximum number of flights as the noise limit, and had not shown that the amendment reduced noise nuisance for residents. Aviation Week summarized the ruling as finding that the government had not adequately justified the restrictions.
With the amendment annulled, the earlier decree, which has no cap on total annual flights, remained in force, and the court set a provisional limit of 27,000 commercial night movements per operating year until a new decision took effect. The House of Representatives debated the new decree with Karremans on September 29, 2026, and the Senate held a short plenary debate the same day. On October 13, 2026, the Senate rejected all five motions on the decree that were put to a vote, including one calling for fewer flight movements when noise standards are exceeded. The government published the decree in the Staatsblad, the official gazette, on October 27, 2026.
In the government’s announcement, Karremans said Schiphol connects the Netherlands with the world and is very important for the country’s earning capacity, and described the decree as a milestone after a multi-year process that strikes a fair balance between residents’ interests and the economy. The government said the airport supports more than 110,000 jobs in the Netherlands, with 68,000 people working directly at the airport and 45,000 at suppliers or other linked organisations, and that more than 300 destinations can be reached directly from Schiphol. AirPro Atlas lists six runways at Schiphol and 66,828,453 passengers in 2024.
The conditional route to 500,000 movements
The government said the 478,000 cap applies until Schiphol reaches its noise target of 20 percent fewer seriously annoyed residents around the airport. After that, growth up to a maximum of 500,000 movements is allowed, but only if the noise burden decreases further. Half of the resulting noise reduction is to benefit the surrounding area and the other half is to create room for more flights. The Senate and the House of Representatives will be involved in the decision to activate the growth system.
Airport executives discussed that path at Routes World 2026 in Frankfurt, Aviation Week reported on October 23, 2026. Joery Strijtveen, head of aviation partnerships at Royal Schiphol Group, said: “If we meet our … targets, which we believe we will, there is potential for future growth in the number of movements.” According to Aviation Week, the airport expects the cap to remain at first and is concentrating on bigger aircraft and fuller use of the infrastructure it already has, with Strijtveen saying more can be done outside the busy morning hours.
Schiphol reports that noise is already falling. In a second interim evaluation of the Balanced Approach, shared with Parliament in August 2026, the ministry reported a 17% reduction in the number of severely affected residents and a 29.8% reduction in residents experiencing sleep disturbance, according to Schiphol. Three of the four interim results exceeded their 15% targets, and the final percentages are expected in December 2026.
Schiphol’s operating forecast for November 1, 2026 to October 31, 2027, which is based on the new decree, expects about 45% of flights to use aircraft from the quietest noise categories and projects the number of severely affected residents to fall to around 150,000 in 2027. Schiphol said quieter aircraft, encouraged through differentiated airport charges, will bring the largest gain.
What comes next
The decree faces a legal challenge. Greenpeace Nederland, Milieudefensie and SchipholWatch said they would ask the Council of State to annul it once it had been officially published, Dutch news agency ANP reported on October 22, 2026. Johan Vollenbroek, speaking for the organisations and residents, said the decision falls well short and does not adequately protect the environment or residents, and that the minister must return to the drawing board, which he said can only be done with fewer flights.
For operators, Schiphol has also set out its own calendar. The Oostbaan runway will undergo a major refurbishment from March 20 to August 8, 2027, the most extensive maintenance project in its history. Schiphol said the Oostbaan is its least-used runway, mainly serving smaller aircraft, so the impact on the area is expected to be limited.
AirPro News analysis
The decree makes noise performance the measure of capacity at Schiphol. Under the government’s design, any growth beyond 478,000 movements depends first on meeting the 20 percent target and then on noise falling further, with half of the resulting noise reduction going to the surrounding area. Schiphol expects quieter aircraft to bring the largest gain, which puts airline fleet choices at the centre of whether the route to 500,000 opens. We would watch the Council of State appeal and the promised Aviation Act amendment on fines just as closely, since both bear on how firmly the new limits can be held.

ICAO Proposes Platform to Fix Cross-Border Flight Rule Enforcement
ICAO’s Legal Committee proposes new guidance and a communication platform after finding 75% of countries lack violation-sharing systems.

The International Civil Aviation Organization (ICAO) Legal Committee has proposed a new communication platform and comprehensive legal guidance to address widespread gaps in how countries enforce international flight rules.
Announced in an October 27, 2026, press release, the proposals target inconsistent enforcement and notification failures regarding aviation violations, particularly those occurring over the high seas or involving foreign-registered aircraft. The initiative aims to standardize accountability under Article 12 of the Convention on International Civil Aviation.
Addressing the data-sharing deficit
Recent reviews by ICAO highlighted significant vulnerabilities in global aviation safety accountability. According to the organization, enforcement of the “Rules of the Air” remains highly inconsistent, with national authorities frequently failing to coordinate on safety infractions.
A legal survey conducted by ICAO revealed that 75% of responding countries currently lack established systems to share information regarding violations committed by foreign aircraft. This data-sharing deficit often results in delayed or lost notifications. The problem is particularly acute for incidents occurring on flights over the high seas, where jurisdictional authority is frequently unclear.
Privacy concerns and legal liabilities have historically discouraged open communication among national aviation authorities. This environment hinders the proactive safety reporting culture that ICAO promotes, leaving regulators unaware of potential repeat offenses by operators crossing international borders.
Standardizing Article 12 enforcement
Article 12 of the Chicago Convention establishes the foundational “Rules of the Air.” Under this framework, every contracting country must enforce these regulations for any aircraft operating within its airspace, as well as for its own registered aircraft regardless of their location. Countries are required to align their national rules with ICAO standards to the greatest extent possible and must prosecute violations.
In practice, national approaches to enforcement vary drastically. Depending on where an incident takes place, pilots and operators might face criminal prosecution, financial penalties, or mandatory retraining. The ICAO Legal Committee, which has drafted 24 international air law treaties since its establishment in 1947, developed the new proposals to bridge these regulatory disparities.
Implementation and next steps
To resolve these inconsistencies, ICAO plans to introduce a first-of-its-kind comprehensive guidance document detailing how member states should implement Article 12.
Alongside the written guidance, the United Nations agency will launch a dedicated communication platform. This system will serve as a centralized point of contact, enabling countries to securely notify one another of potential violations and coordinate cross-border enforcement actions.
AirPro News analysis
The introduction of a centralized communication platform for violation reporting represents a significant shift in international aviation oversight. While ICAO cannot force sovereign nations to harmonize their penal codes, providing a secure channel for data sharing removes the technical and administrative barriers that currently allow operators to evade scrutiny when crossing borders. If widely adopted, this platform could effectively close the loophole where a pilot or airline accumulates a record of infractions in foreign airspace without their home regulator ever being notified.

EASA Annual Safety Review 2026 European Aviation Safety
EASA’s Annual Safety Review 2026 shows European aviation safety remained stable in 2025, with one fatal CAT aeroplane accident recorded.

The European Union Aviation Safety Agency (EASA) published its Annual Safety Review 2026 on October 22, 2026, indicating that European aviation safety performance remained stable throughout the 2025 operational year. The comprehensive statistical analysis, formally announced on October 26, 2026, tracks safety performance across all aviation domains to guide practical risk reduction actions and regulatory updates.
Commercial Air Transport safety performance
The review of the 2025 operational year showed that fatal accidents and fatalities remained at or below the 10-year average across most aviation domains. In Commercial Air Transport (CAT) operations involving aeroplanes, EASA recorded one fatal accident. The event involved an air taxi flight that crashed after declaring an emergency, resulting in eight fatalities.
Beyond the single fatal accident, CAT aeroplane operations in 2025 experienced 16 non-fatal accidents and 51 serious incidents. The agency also recorded 17 serious injuries within this domain. EASA attributed these injuries to a variety of operational events, including turbulence, airstair disembarkation, wake vortex encounters, Traffic Collision Avoidance System (TCAS) maneuvers, emergency evacuations, and pushback operations.
In a press release accompanying the report, EASA noted the overall stability of the European aviation system.
“The overall picture shows that, in almost all domains, the number of fatal accidents and fatalities remained at or below the average for the previous 10 years. This suggests that safety performance remained broadly stable or has been improved in most areas,” the agency stated.
Rotorcraft operations and leading safety risks
The safety data for Commercial and Specialised Helicopters operations in 2025 included one fatal accident, which resulted in three fatalities. The rotorcraft sector also recorded four non-fatal accidents and 14 serious incidents during the same 12-month period.
The Annual Safety Review identified and ranked the leading safety risks for Commercial Air Transport based on the 2025 data. The top five risks were identified as fire, smoke and pressurisation events, followed by aircraft upset, airborne collision, collision on runway, and runway excursions.
While the broader statistical trends point to a stable safety environment, EASA emphasized that risk levels fluctuate depending on the specific aviation sector. “However, the results varied between different types of operation, underlining the need for continued vigilance and targeted safety action,” the agency noted.
EASA’s evolving safety framework
The Annual Safety Review serves as a critical data-driven input for the European Safety Risk Management (SRM) process. The findings from the 2026 report will feed directly into future updates of the European Plan for Aviation Safety (EPAS), which dictates the regulatory and safety priorities for EU member states.
For the 2026 edition, EASA introduced a new six-page Annual Safety Review Summary. This addition was designed to present headline figures and leading safety risks in a more accessible format for commercial air transport aeroplanes, rotorcraft, and general aviation.
The publication of the safety review aligns with a broader push by EASA to address emerging and persistent operational risks in European airspace. Throughout October 2026, the agency updated several safety guidelines, including revisions to the Easy Access Rules for Aircrew on October 16, 2026, and the CS-GEN-MMEL on October 15, 2026. EASA also recently hosted a joint workshop with EUROCONTROL to address Europe’s Global Navigation Satellite System (GNSS) interference Action Plan, targeting a growing operational safety concern for flight crews operating in and around European airspace.
