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.

U.S. House Ends DHS Shutdown Funding TSA and Key Agencies

The U.S. House passes bipartisan bill ending the 76-day DHS shutdown, funding TSA, FEMA, Coast Guard, and Secret Service through September 2026.

Published

on

This article summarizes reporting by Bloomberg and Erik Wasson. This article summarizes publicly available elements and public remarks.

The U.S. House of Representatives has voted to end the longest partial government shutdown in American history, passing a bipartisan funding measure for the majority of the Department of Homeland Security (DHS). According to reporting by Bloomberg, the legislative move on April 30, 2026, comes just days before emergency funds used to pay Transportation Security Administration (TSA) workers were set to expire, averting widespread disruptions at Airports nationwide.

The 76-day lapse in appropriations, which began on February 14, 2026, impacted approximately 193,867 employees, representing nearly 10% of the federal workforce. The newly passed bill, which previously cleared the Senate unanimously, secures funding for the TSA, the Federal Emergency Management Agency (FEMA), the Coast Guard, and the Secret Service through September 2026.

However, the legislation notably excludes funding for Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP). House leadership has opted for a two-track strategy, planning to fund these specific agencies through a separate, partisan budget reconciliation process.

The Toll on Aviation and the TSA

Staffing Shortages and Operational Strain

The prolonged shutdown placed immense financial and operational strain on the nation’s aviation security apparatus. Because TSA agents are classified as essential personnel, they were required to continue working without standard pay. Industry data indicates that the financial burden led to severe attrition, with more than 1,000 TSA officers resigning during the 76-day period.

This loss of personnel directly impacted airport operations. In March 2026, daily call-out rates at security checkpoints surged to a nationwide average of 11%, up from a pre-shutdown baseline of 4%. According to DHS figures, some individual airports reported absentee rates exceeding 40%, resulting in hours-long security lines and missed flights at major hubs.

Emergency Funding Exhaustion

To prevent total systemic collapse, President Donald Trump authorized emergency funding via executive memorandum in late March to compensate TSA employees. However, DHS Secretary Markwayne Mullin recently cautioned that these reserves were rapidly depleting ahead of a critical early May deadline.

“My payroll through DHS is just over $1.6 billion every two weeks,” Mullin warned prior to the vote, noting that once depleted, “there is no emergency funds after that.”

Ha Nguyen McNeill, the senior official performing the duties of TSA Administrator, highlighted the severe personal toll on the workforce during a March congressional hearing. She testified that dedicated public servants were running out of options to feed their families.

“Many have received eviction notices, lost their childcare, missed bill payments and been charged late fees,” McNeill stated.

Political Deadlock and the Path Forward

Origins of the Impasse

The historic 76-day shutdown stemmed from a deep partisan divide over immigration enforcement. The standoff was catalyzed by the fatal shootings of two U.S. citizens by federal agents during protests against an immigration crackdown in Minneapolis. In response, Democratic lawmakers demanded operational reforms for ICE, including a ban on agents wearing masks and a requirement for judicial warrants before entering private residences.

The Trump administration and congressional Republicans rejected these conditions, leading to the prolonged funding lapse.

The Two-Track Legislative Strategy

To bypass the deadlock and reopen critical agencies like the TSA, House Speaker Mike Johnson orchestrated a bifurcated approach. The first track involved passing the Senate-approved bipartisan bill to fund the bulk of the DHS via a voice vote.

“It is about damn time,” remarked Rep. Rosa DeLauro (D-Conn.), the top Democrat on the House Appropriations Committee, following the successful vote.

The second track involves utilizing the budget reconciliation process to fund ICE and Border Patrol, allowing Republicans to bypass Democratic opposition in the Senate. House Republicans have already adopted a budget resolution aiming to allocate $70 billion for immigration enforcement and deportations through the remainder of the presidential term in January 2029.

AirPro News analysis

At AirPro News, we observe that while the immediate threat of airport chaos has been mitigated, the aviation sector may still face lingering headwinds. The loss of over 1,000 TSA officers cannot be rectified overnight. According to DHS estimates, recruiting and training a new TSA officer requires four to six months.

As the summer travel season approaches, and with the upcoming FIFA World Cup drawing closer, airports may continue to experience elevated wait times and staffing bottlenecks. The U.S. airlines trade group, Airlines for America, recently urged Congress to provide stable funding, emphasizing that the aviation system should not be subjected to political brinkmanship. We anticipate that airlines and airport operators will need to implement robust contingency plans to manage passenger flow while the TSA works to rebuild its depleted ranks.

Frequently Asked Questions

When did the DHS shutdown begin and end?

The partial shutdown began on February 14, 2026, and effectively ended on April 30, 2026, lasting 76 days. It is the longest partial government shutdown in U.S. history.

Which agencies are funded by the new bill?

The bipartisan bill funds the TSA, FEMA, the Coast Guard, and the Secret Service through September 2026.

Why were ICE and Border Patrol excluded from this bill?

Due to partisan disagreements over operational reforms following incidents in Minneapolis, Republicans plan to fund ICE and Border Patrol separately through a budget reconciliation process, bypassing the need for Democratic support.

United Airlines Flight 169 Contacts Light Pole Near Newark Airport

United Airlines Flight 169 struck a light pole over the New Jersey Turnpike during approach to Newark Liberty Airport; FAA investigates incident.

Published

on

This article summarizes reporting by WABC.

A United Airlines Boeing 767-400 arriving from Venice, Italy, made unexpected contact with ground infrastructure during its final approach to Newark Liberty International Airport (EWR) on Sunday afternoon. According to reporting by WABC, the widebody aircraft struck a light pole situated above the New Jersey Turnpike, subsequently causing damage to a commercial tractor-trailer traveling on the roadway below.

Despite the unusual collision, United Airlines Flight 169 landed safely on Runway 29. Authorities confirmed that none of the 221 passengers or 10 crew members on board were injured. The incident, which occurred at approximately 2 p.m., is now the subject of a federal investigation to determine how the aircraft descended low enough to strike the pole.

We at AirPro News are monitoring the ongoing safety reviews. The event highlights the tight tolerances and critical obstacle clearance limits associated with major airports surrounded by dense highway infrastructure.

Incident Details and Immediate Aftermath

Flight 169’s Approach

The aircraft involved was completing a transatlantic journey from Venice. As it neared Newark’s Runway 29, WABC reports that the plane’s trajectory brought it into contact with a light pole over the southbound lanes of the New Jersey Turnpike. The aircraft sustained what United Airlines described as minor damage and was able to taxi to the gate under its own power.

In a statement provided to the media, the airline confirmed its internal review process regarding the event:

“Our maintenance team is evaluating damage to the aircraft and we will investigate how this occurred,” United Airlines stated.

Impact on the Ground

The strike had immediate consequences for traffic on the New Jersey Turnpike. The falling debris or direct contact affected a northbound tractor-trailer operated by Baker’s Express. The driver, identified by WABC as Warren Boardley of Baltimore, was transporting bread products to an airport depot at the time.

Chuck Paterakis, an executive with the bakery’s parent company, told ABC News that the driver felt the impact directly above his cab.

“The driver experienced a commercial plane’s tires landing on the tractor or brushing the top of the tractor,” Paterakis noted.

According to WABC, Boardley was able to safely pull the vehicle over. He sustained minor cuts to his arms from shattered glass, was treated at a local hospital for non-life-threatening injuries, and has since been released. Paterakis confirmed that the trailer itself and its cargo remained intact, expressing gratitude that the outcome was not more severe.

Investigations and Operational Impact

Official Responses

Following the incident, multiple agencies responded to secure the scene and begin evidence collection. The Port Authority Police Department and New Jersey State Police managed the situation on the Turnpike. Meanwhile, airport officials quickly conducted runway inspections at Newark Liberty, allowing normal flight operations to resume shortly after the strike, according to WABC.

The Federal Aviation Administration (FAA) has officially launched an investigation into the event. FAA personnel, alongside representatives from the New Jersey Turnpike Authority, were on-site Sunday evening to inspect the damage and gather data.

AirPro News analysis

While runway approaches are designed with strict obstacle clearance surfaces (OCS) to ensure aircraft maintain a safe distance from ground structures, incidents of this nature are exceedingly rare. Runway 29 at Newark features a specific glide path designed to keep arriving aircraft safely above the adjacent New Jersey Turnpike.

We note that investigators will likely focus on the aircraft’s altimeter settings, the flight crew’s adherence to the glideslope, and potential environmental factors such as wind shear or downdrafts that could have caused a momentary loss of altitude. The flight data recorder (FDR) and cockpit voice recorder (CVR) will be critical in determining why the Boeing 767-400 breached the minimum safe altitude over the highway.

Furthermore, the Boeing 767-400 is a large widebody aircraft, and its main landing gear hangs significantly lower than the pilot’s eye level in the cockpit during a flared landing attitude. We expect the FAA investigation to examine whether the crew experienced a visual illusion or if a sudden sink rate contributed to the gear clipping the light pole. The safe recovery and landing of the aircraft suggest the flight crew maintained control despite the impact.

Frequently Asked Questions

What flight was involved in the Newark airport incident?
United Airlines Flight 169, a Boeing 767-400 traveling from Venice to Newark.

Were there any injuries on the plane?
No. According to WABC, all 221 passengers and 10 crew members were unharmed.

Was anyone on the ground injured?
Yes, the driver of a commercial tractor-trailer sustained minor cuts from broken glass but was treated and released from the hospital.

Who is investigating the collision?
The Federal Aviation Administration (FAA) is leading the investigation, with assistance from local authorities including the Port Authority Police and New Jersey State Police.
