WestJet Boeing 737 Landing Gear Collapse Investigation in St Maarten
TSB investigates WestJet Boeing 737 landing gear collapse in St Maarten linked to a fractured aft trunnion pin from maintenance issues.
Anatomy of a Landing Gear Failure: TSB Investigates WestJet Incident in St. Maarten
On September 7, 2025, a routine landing for a WestJet Boeing 737-800 at the scenic Princess Juliana International Airport in St. Maarten took an unexpected turn. The aircraft, arriving from Toronto with 157 passengers and 6 crew members, experienced a significant mechanical failure during its landing on Runway 10. The right main landing gear collapsed, causing the aircraft’s right engine to strike the runway surface. The event led to substantial damage to the aircraft and a prompt, controlled evacuation of everyone on board.
In the world of aviation safety, what happens after an incident is just as critical as the event itself. Under international aviation protocols, the St. Maarten Civil Aviation Authority delegated the complex task of investigation to the Transportation Safety Board of Canada (TSB). The TSB, working in close collaboration with American counterparts like the National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA), as well as with Boeing and WestJet, immediately began to piece together the sequence of events. One of the first, and most crucial, findings from the flight data recorder was clear: this was not a hard landing, immediately shifting the focus from operational factors to the mechanical integrity of the aircraft.
This incident does not exist in a vacuum. As investigators delve deeper, the focus has narrowed to a specific, critical component known as the aft trunnion pin. This piece of hardware has been implicated in previous landing gear failures on other Boeing 737 aircraft. The TSB’s investigation, therefore, carries implications that extend beyond a single flight, touching upon maintenance procedures and the lifecycle management of one of the world’s most common commercial aircraft.
The Incident and Initial Findings
The moments following the gear collapse were a testament to crew training and procedural discipline. With the aircraft disabled on the runway, the crew initiated a planned evacuation. Passengers and crew exited the aircraft using the emergency slides on the left side, away from the damaged right side. The evacuation was swift and orderly, resulting in only one reported minor injury sustained during the process. No injuries were reported as a direct result of the landing gear failure itself, a positive outcome in a challenging situation.
The Fractured Pin: A Critical Clue
Once the site was secured, TSB investigators began a meticulous examination of the aircraft. Their attention was quickly drawn to the failed right main landing gear, where they discovered that the aft trunnion pin had fractured. This pin is a crucial structural component that secures the landing gear assembly to the wing, designed to withstand immense forces during takeoff and landing. Its failure is a significant structural event.
The two fractured portions of the pin were carefully recovered from the site and transported to the TSB’s Engineering Laboratory in Ottawa. There, they will undergo detailed metallurgical and forensic analysis to determine the precise cause of the fracture. This examination will look for evidence of fatigue, stress corrosion, or manufacturing defects, providing a scientific basis for understanding why the component failed when it did.
The TSB also noted a key piece of the aircraft’s history: the right main landing gear assembly had undergone a complete overhaul in 2016. While this is a standard procedure for aircraft components, the date and details of this maintenance work will undoubtedly form a key part of the ongoing investigation as the team builds a complete picture of the component’s service life.
The initial review of the flight data recorder data indicates that this was not a hard landing event. This finding directs the investigation away from operational factors and squarely towards the aircraft’s mechanical integrity.
A Pattern of Failures: The Aft Trunnion Pin in Focus
Standard investigative practice involves looking for patterns, and the TSB is currently reviewing previous occurrences involving aft trunnion pin fractures on Boeing 737 aircraft. This line of inquiry is particularly relevant, as the NTSB has investigated at least two similar incidents in recent years, both of which point to a potential systemic issue related to maintenance procedures rather than a design flaw.
Historical Precedents and Maintenance Links
In August 2023, an Alaska Airlines Boeing 737-800 experienced a landing gear collapse. The subsequent NTSB investigation found that the left main landing gear’s aft trunnion pin had fractured due to a fatigue crack. The probable cause was determined to be “excessive grinding” during a maintenance overhaul, a procedure that inadvertently introduced heat damage and created the conditions for the crack to develop and propagate over time.
This was not an isolated case. A similar incident in December 2019 involving a United Airlines Boeing 737-800 was also traced back to a fractured aft trunnion pin. Once again, the NTSB investigation concluded that a fatigue crack had formed due to “excessive grinding” during an overhaul. These repeated findings highlight the critical importance of adhering to precise, validated procedures during the complex process of refurbishing major aircraft components.
These historical cases provide a crucial context for the WestJet investigation. They suggest that the focus will likely be on the maintenance, repair, and overhaul (MRO) history of the component. Landing gear assemblies are periodically removed from aircraft and completely disassembled, inspected, repaired, and reassembled by specialized facilities. The NTSB’s findings in the Alaska and United cases show that even minor deviations from approved procedures in this highly technical process can introduce latent defects that may not become apparent for years, ultimately leading to in-flight failures.
Conclusion: Awaiting the Final Report
The investigation into the WestJet landing in St. Maarten is a clear example of the methodical, evidence-based approach that defines modern aviation safety. The key facts established so far are that the incident was not caused by a hard landing, but by the fracture of the right main gear’s aft trunnion pin. This specific component has a documented history of failure in other Boeing 737-800s, with previous investigations pointing to improper maintenance during overhauls as the root cause.
The TSB’s final report, which will be released after the completion of the laboratory analysis and a full review of all evidence, will provide the definitive cause of this specific incident. Its findings will be closely watched by airlines, MRO facilities, and regulators worldwide. Depending on the outcome, it could lead to revised maintenance protocols or airworthiness directives to prevent similar occurrences, reinforcing the continuous cycle of learning and improvement that makes air travel one of the safest forms of transportation.

Jet2 Contractor Seriously Injured After Fall at Manchester Airport
A contractor fell from a Jet2 plane at Manchester Airport, sustaining serious injuries. Jet2 is conducting a full investigation into the incident.
This article summarizes reporting by Manchester Evening News and Paul Britton.
A severe incident at Manchester Airport on Saturday morning left an aviation contractor with serious injuries after falling from a Jet2 aircraft. Emergency responders were dispatched to the tarmac following the fall, which occurred near the rear of the plane.
According to reporting by the Manchester Evening News, the injured individual is believed to be an aircraft engineer employed by a third-party provider. The worker sustained multiple severe injuries, including fractures to the arm and leg, and was transported to a local hospital for ongoing treatment.
The aircraft involved was reportedly preparing for a scheduled departure to Tenerife when the fall occurred at approximately 8:00 a.m. local time. Jet2 has since confirmed that a comprehensive investigation into the workplace accident is underway.
Emergency Response on the Tarmac
Immediate Medical Attention
Following the fall, paramedics from the North West Ambulance Service were immediately scrambled to the scene to provide critical care. Witnesses cited by the Manchester Evening News noted that emergency personnel erected medical screens around the injured contractor while administering first aid on the tarmac.
The prompt response highlights the severe nature of the injuries sustained. The worker, whose identity has not been publicly released, remains hospitalized as medical teams address the significant bone fractures resulting from the drop.
Aircraft and Equipment Positioning
Photographs and witness accounts from the scene indicate that the Jet2 aircraft had a rear door open near the tail section at the time of the accident. Mobile passenger stairs were also observed in close proximity to the aircraft.
While the exact sequence of events leading to the fall remains unconfirmed, the positioning of the open door and the mobile stairs will likely be a focal point for safety investigators examining how the contractor fell from the elevated threshold.
Jet2 Launches Full Investigation
Airline Acknowledges Third-Party Involvement
In the wake of the accident, Jet2 issued a public statement acknowledging the event and clarifying the worker’s employment status. The airline noted that the individual was not a direct employee but worked for an external service provider contracted at the airport.
In a statement provided to the press, a Jet2 spokesperson confirmed the ongoing inquiry:
“We are unable to confirm further details at present, however, can confirm that a full investigation has been launched.”
The airline also emphasized that they are working to provide necessary support to those affected by the morning’s events.
AirPro News analysis
Ground handling and aircraft maintenance are inherently high-risk environments, particularly when personnel are operating near open cabin doors or elevated service platforms. Standard operating procedures typically dictate strict protocols for the placement and removal of mobile stairs, as well as the securing of aircraft doors when ground equipment is not flush against the fuselage.
When a worker falls from an aircraft door, investigators usually examine whether safety harnesses were required, if the mobile stairs were prematurely moved, or if there was a miscommunication between the ground crew and the personnel inside the cabin. The involvement of a third-party contractor also means that the investigation will likely scrutinize the coordination and safety oversight between Jet2 and its service providers at Manchester Airport.
The aviation industry maintains rigorous safety management systems to mitigate the risks associated with tarmac operations. Falls from height remain one of the leading causes of occupational injuries in aviation maintenance and ground handling. Regulatory bodies frequently collaborate on investigations of this nature to determine if workplace safety regulations were breached. The findings from Jet2’s internal investigation will likely be utilized to prevent future occurrences and ensure that third-party contractors adhere to stringent safety standards.

ICAO Issues Mental Health Guidance for Aviation in Conflict Zones
ICAO calls for mental health support for aviation personnel amid Middle East conflict, highlighting safety risks and pilot union demands.
This article is based on an official press release from the International Civil Aviation Organization (ICAO), supplemented by industry research and reporting.
On April 9, 2026, the International Civil Aviation Organization (ICAO) issued urgent guidance aimed at mitigating the significant mental stress experienced by aviation personnel operating in or near active conflict zones. The United Nations aviation agency formally classified these mental health impacts as foreseeable, cumulative, and critical to overall operational safety.
This directive arrives during a period of unprecedented strain on global aviation networks. A volatile, six-week-long military conflict in the Middle-East involving the United States, Israel, and Iran has forced complex flight rerouting and widespread airspace closures since late February 2026.
According to the official ICAO press release, the agency is calling on member states, aviation organizations, and public health partners to collaboratively implement proactive, evidence-based strategies. We note that this guidance seeks to protect not only flight crews but the entire aviation workforce, including Airlines and ground staff, who are currently facing elevated stress, anxiety, and fatigue.
ICAO’s Urgent Directive on Mental Well-Being
A Multilayered Approach to Safety
The ICAO guidance outlines a multilayered approach to reducing mental stress, emphasizing coordinated action across organizational, operational, and individual levels. The agency urges aviation organizations to adopt clear policies prioritizing mental well-being and to implement operational changes that minimize unnecessary stress.
“Supporting mental well-being is both a duty of care and a safety requirement.”
, International Civil Aviation Organization (ICAO)
The press release highlights that personnel across all aviation functions are susceptible to conflict-related pressures. If left unaddressed, ICAO warns that these effects can compromise both individual well-being and operational safety. To combat this, ICAO recommends providing consistent access to qualified mental health resources, targeted training to recognize early signs of distress, and timely post-incident support such as professional psychological care and peer support.
Effective communication is also highlighted as essential. ICAO encourages aviation leadership to prioritize two-way dialogue, ensuring personnel can discuss operational challenges and raise concerns without fear of stigma.
The Geopolitical Catalyst and Operational Strain
Navigating the Middle East Aviation Crisis
The urgency of ICAO’s April 9 bulletin is directly tied to the ongoing Middle East aviation crisis. Industry research indicates that the European Union Aviation Safety Agency (EASA) has extended its advisory for airlines to avoid Middle Eastern and Gulf airspace until April 24, 2026. Despite these warnings, several major carriers continue to operate through narrow, congested safe corridors, significantly increasing the cognitive load on flight crews.
This geopolitical instability has led to severe capacity reductions. As of early April 2026, industry data shows Emirates operating at approximately 69 percent of its normal capacity, while Qatar Airways has been limited to around 26 percent. Furthermore, regulators such as India’s Directorate General of Civil Aviation (DGCA) have granted temporary exemptions extending maximum flight times and duty periods for airlines like Air India until April 30, 2026, to accommodate longer rerouted flights via Egypt and Oman.
Pilot Unions Push Back Against Commercial Pressures
Demands for Commander Authority
As operational complexities mount, pilot unions are increasingly vocal about the toll on their members. On April 6 and 7, 2026, the International Federation of Air Line Pilots’ Associations (IFALPA) issued a firm position paper demanding that an aircraft commander’s decision to refuse operations in or reroute around war-torn airspace must be final and non-negotiable.
According to industry reports, IFALPA explicitly warned against the normalization of degraded safety conditions, noting that repeated uneventful flights through conflict zones may mask evolving dangers.
“The normalisation of degraded conditions must be avoided, as the passage of time in a protracted conflict does not diminish the operational complexity.”
, IFALPA Position Summary
Similarly, the Airline Pilots’ Association of India (ALPA) has urged the DGCA to suspend flight operations into high-risk Middle Eastern zones until centralized risk assessments are conducted. ALPA argues that commercial airlines lack the necessary military intelligence capabilities to adequately evaluate active threats.
AirPro News analysis
The intersection of mental health and operational safety is rapidly becoming a defining issue for the aviation industry in 2026. As airlines grapple with surging war-risk insurance premiums and the necessity of fuel surcharges due to longer routes, the commercial pressure to maintain schedules is immense. However, ICAO’s formal recognition of mental stress as a “safety-critical” factor shifts the paradigm. By explicitly linking psychological well-being to the risk of human error, ICAO is providing pilot unions with regulatory backing to push back against extended duty hours and hazardous routing. While a temporary two-week ceasefire was announced around April 7, 2026, the underlying volatility remains. We assess that the true test of this guidance will be whether national regulators enforce these mental health provisions as strictly as traditional mechanical Safety standards.
Frequently Asked Questions (FAQ)
Who is covered by the new ICAO mental health guidance?
According to the ICAO press release, the guidance covers personnel across all aviation functions. This includes flight crews, air traffic controllers, cabin crews, maintenance teams, and ground staff operating in or near conflict zones.
Why are flight times being extended?
Due to airspace closures in the Middle East, airlines are forced to fly longer, rerouted paths to avoid active conflict zones. Regulators in some countries have granted temporary exemptions to extend maximum flight duty periods to accommodate these longer routes, though pilot unions have flagged this as a significant fatigue risk.
How long are the current airspace advisories in effect?
Industry data notes that the European Union Aviation Safety Agency (EASA) has extended its advisory to avoid Middle Eastern and Gulf airspace until April 24, 2026, while certain duty time exemptions extend to April 30, 2026. ICAO states it will continue to monitor developments and refine its recommendations as the situation evolves.
