Latam Airlines flight LA3122 halts takeoff at Congonhas as child suffers severe finger cut in seatbelt

A young passenger sustained a deep laceration to a finger after getting caught in a seatbelt mechanism aboard a Latam Airlines Brasil domestic service at Congonhas Airport in southern São Paulo. The incident occurred during departure preparations on Monday, September 28, 2026, prompting flight operations to halt immediately on the tarmac and activating emergency medical responders stationed across the airport perimeter.

The medical emergency unfolded aboard flight LA3122, a scheduled shuttle service set to fly from São Paulo to Santos Dumont Airport in central Rio de Janeiro. Travelers had already boarded the aircraft and stowed their cabin luggage when the unexpected injury generated immediate concern inside the passenger cabin.

A physician traveling on the same aircraft stepped forward to deliver urgent on-site trauma care while the jet was being guided across the airport ramp. The quick assessment helped stabilize the young patient as flight attendants worked to coordinate with the cockpit.

The captain promptly aborted the departure procedure, steered the narrow-body jet back toward the passenger boarding gate, and grounded the airframe for technical inspections. The unexpected operational delay ultimately triggered the cancellation of the subsequent return leg, flight LA3929, between Rio de Janeiro and São Paulo.

Airport paramedics received the injured minor at the terminal gate before transferring the patient to an external hospital with ongoing logistical accompaniment from airline customer care personnel. The family remained under corporate assistance throughout the specialized clinical evaluation process.

Tarmac medical emergency disrupts departure at Congonhas

The incident occurred inside an Airbus A319 operating flight LA3122, one of the high-frequency air shuttle services connecting Brazil’s two largest business capitals. During the standard pushback maneuver, in which a ground tow tug repositions the airliner backward from the jet bridge toward the taxiway prior to engine startup, the child suffered a severe pinch and laceration against the metal components of the seatbelt latch.

Surrounding passengers quickly mobilized to assist the family until an onboard medical practitioner intervened. The volunteer physician applied emergency measures directly in the passenger seat to staunch active bleeding and determine whether the patient was stable enough for air travel. Recognizing the severity of the tissue injury and the need for specialized surgical evaluation, the cabin crew immediately informed the flight deck that proceeding with takeoff was not viable.

The captain radioed ground controllers to declare a priority medical emergency, suspended the movement of the aircraft on the taxiway, and requested an immediate path back to the boarding pier. Radio transmissions between the flight deck and Congonhas ground controllers, recorded by civil aviation observers, confirmed the urgent plea for ramp medical assistance before the Airbus A319 completed its return docking maneuver.

Operational details of the affected commercial service

• Scheduled departure: Flight LA3122 operated on an Airbus A319 narrow-body aircraft.
• Intended itinerary: Congonhas Airport in São Paulo to Santos Dumont Airport in Rio de Janeiro.
• Disrupted sector: Return flight LA3929 across the air shuttle corridor canceled following equipment retention.
• Phase of operation: Ground pushback and repositioning on the tarmac prior to runway taxi.
• Date of the incident: Monday, September 28, 2026.

Gate deplaning and patient transfer to specialized emergency care

Once the airliner docked securely at the terminal jet bridge, ground crews assisted the injured passenger and family members off the plane to undergo an initial clinical screening. In line with Brazilian airport contingency regulations, primary stabilization and sterile dressings were administered inside the dedicated medical station situated within Congonhas Airport.

After local airport medical staff completed basic stabilization, a municipal emergency ambulance transported the child and accompanying relatives to a specialized hospital facility within the metropolitan network of São Paulo. Latam Airlines Brasil confirmed that an employee from its passenger assistance division was dispatched alongside the family to remain present at the medical center and handle ongoing logistical requirements.

In an official press statement released on Monday evening, the air carrier expressed deep sympathy toward the relatives of the young traveler. Latam Airlines Brasil stated that it stands in solidarity with the child and family following the occurrence reported prior to the departure of flight LA3122, adding that all standard protocols for urgent ground medical assistance were deployed without delay.

Air shuttle network impacts and passenger assistance measures

The unplanned gate return and the mandatory paperwork accompanying emergency medical disembarkations created substantial disruptions for the operational schedule of the aircraft. In accordance with strict civil aviation safety guidelines, the Airbus A319 remained grounded on the apron at Congonhas throughout the remainder of Monday afternoon for formal review. This unplanned downtime left the carrier with no operational window to operate the return rotation, flight LA3929, from Santos Dumont Airport back to São Paulo.

Travelers holding reservations on the canceled sector or those who experienced extensive schedule changes across the Rio-São Paulo corridor were directed to consult digital rebooking channels or speak directly with airport service agents. Latam Airlines Brasil made provisions for complimentary rebooking on subsequent scheduled departures between the two cities or complete ticket refunds without administrative cancellation fees.

Civil aviation safety standards and inspection of latch mechanisms

Civil aviation authority directives require all occupants to remain securely buckled during pushback maneuvers, surface taxiing, takeoff runs, and final descent stages. In cases involving infants and young children occupying dedicated passenger seats, flight safety regulations mandate that cabin crew members visually confirm that passenger restraints are properly fitted and latched before the aircraft initiates any movement away from the terminal.

Industry technical reviews, including reporting by aviation journalist Mateus Santana, indicate that investigators are still assessing the exact mechanical interaction that led to the severe cut. As of Tuesday, September 29, 2026, regulatory agencies and carrier representatives have not released public medical assessments regarding the depth of the laceration, the exact age of the passenger, or the mechanical defect that may have caused the trauma.

Aviation safety technicians and internal airline maintenance personnel continue to review flight reports and inspect the restraint hardware fitted to the specific seat on the Airbus A319. These technical inspections aim to verify whether the seatbelt mechanism had structural damage or unexpected mechanical wear that contributed to the onboard injury.
