On August 31, 2026, LATAM Airlines Flight LA3858, an Airbus A320 (PR-MYO) from Sao Paulo-Guarulhos, suffered a low-speed runway excursion at Cascavel Airport (CFC) in Parana, Brazil, at about 09:45 local time after landing on wet Runway 15. All 145 passengers and 6 crew disembarked safely with no injuries, while the airport issued a NOTAM closure and LATAM cancelled return flight LA3859 with rebooking via Foz do Iguacu.

Let me explain why a landing that looked completely normal for 95% of the rollout turned into a textbook case study on wet-runway risk. What happens in those last 15 knots matters more than you think.

No Injuries, But a Full Stop for Cascavel Operations

The first fact to lock in: 151 people walked away unhurt. 145 passengers and 6 crew on the 14-year-old A320 left the aircraft on the grass verge without a single reported injury, a result crews and emergency teams earned through fast, disciplined steps.

Flight tracking data shows LA3858 departed Sao Paulo/Guarulhos (GRU) as a routine domestic service to western Parana. Near Cascavel, heavy rain had already reduced visibility and left standing water on the surface. The crew entered a brief holding pattern to assess conditions, then got clearance for Runway 15 at approximately 09:45 local time (12:45 UTC).

Touchdown and initial deceleration looked normal — thrust reversers deployed, speed bled off as expected. The problem came during the slow-speed turn and backtrack phase. At roughly 15 knots ground speed, the nose gear lost traction on the saturated pavement and the jet drifted past the paved edge into the soft grass beside the threshold. No hard braking, no high-speed overrun. Just a slow slide that left the twin-engine jet immobilized off the pavement.

And here is the best part for everyone on board — emergency protocols worked.

How the Evacuation and Airport Response Unfolded

Within minutes, local emergency teams ringed the aircraft, secured the perimeter, and brought buses to move passengers to the terminal. According to the official airline statement, “Our primary commitment remains the absolute safety of our passengers and crew” and “full assistance is actively being extended to every affected customer.”

Still, the ripple effect was instant. Cascavel Airport (CFC), formally Coronel Adalberto Mendes da Silva Airport, issued a NOTAM temporarily closing the airfield for inspections. That matters if you had a ticket through CFC on August 31 and September 1.

• LATAM Flight LA3859 — the return leg to Sao Paulo — was cancelled outright.
• Passengers were offered ground transport and rebookings through nearby hubs, most often Foz do Iguacu (IGU), about 140 km west by road.
• Other regional departures faced delays or diversions until friction tests and a runway check were complete.

What is more, the airline’s ground teams stayed airside for hours, checking the pavement, the turn pad, and the grass verge where PR-MYO came to rest.

Why Weather and Runway Surface Are at the Center of the Inquiry

Why did a slow taxi-like turn cause more trouble than the landing itself? Investigators are looking hard at water, not pilot input alone.

Video from shortly before touchdown shows sheets of spray kicked up as tyres met wet asphalt — a visual clue that the film of water was deep enough to change how rubber meets runway. On a soaked surface, even low-speed steering can turn slick if drainage cannot shed water fast enough.

Brazil’s aeronautical accidents prevention authority has opened a formal inquiry. According to official updates, teams are reviewing:

• water film depth and drainage capacity on Runway 15 and its turn pad
• rubber build-up near turning points, where friction often drops first
• braking action reports from preceding arrivals that morning
• turn-pad geometry, runway slope, and whether the layout met safety margins during intense rain

Sound familiar? Tropical downpours can dump centimeters in minutes across Parana, and smaller regional fields feel it first. The air still smells of jet fuel and wet earth, tyres hiss on the sheen, and underfoot the verge goes soft. That combination — hard rain, a thin water layer, and a tight turn at low speed — is exactly what analysts are testing with friction runs now.

Not only that, the question extends beyond one aircraft. Were reported friction values still within limits when LA3858 was cleared to land? Did localized pooling near the threshold reduce directional control during the backtrack? Those answers will shape the next advisory for pilots using CFC in similar weather.

What This Means If You Are Flying Through Western Parana This Week

If Cascavel was on your itinerary, think alternates and timing. Here is a clear plan that keeps you moving without guesswork.

1. Check status before you go

Look up the current NOTAM for CFC and confirm your flight in the LATAM app or at the airport desk. Morning rain is the pattern — early flights are most likely to be held or diverted.

2. Know your rebooking pathway

LATAM has been routing affected travelers via Foz do Iguacu (IGU) with buses between cities. Keep your booking reference handy and ask for the next confirmed seat rather than an open waitlist. If you booked via an agent, call them and LATAM in parallel to save time.

3. Build in ground time

The road transfer Cascavel–Foz do Iguacu runs about 2 to 2.5 hours depending on rain and traffic. If you accept a rebook from IGU, leave a buffer and keep receipts for any assistance or meals provided due to the disruption.

4. Pack for wet-field ops

Carry a light waterproof layer, keep electronics in a sealed pouch, and download offline maps. Regional terminals are compact, so a bus-boarding call comes with little warning when weather windows open.

Travelers tracking wider airlines updates should watch for a follow-up bulletin once friction tests are logged and the NOTAM is lifted. For context on how Brazil’s regional network handles peak-season demand, our tourism desk keeps a rolling overview of airport advisories and alternate gateways.

What Happens to the Aircraft and the Runway Next

PR-MYO will not fly until engineers clear every system that touched unpaved ground. That means detailed checks on the nose and main landing gear, lower fuselage, and both engines for stress or debris ingestion. Even a slow excursion can throw grass and grit into areas you cannot see from the outside.

At the same time, airfield technicians are running friction tests along Runway 15, especially at the turnaround area where traction fell away. Only when those numbers return to approved margins will the NOTAM be lifted and normal scheduling resume.

LATAM is cooperating fully with regulators, handing over flight data recorder and cockpit voice recorder files. Those logs will show exact rudder and nose-wheel inputs, brake pressures, and engine settings in the critical seconds before the drift. And here is the larger point — findings from Cascavel are expected to feed into standardized wet-weather procedures for regional airports across South America, where sudden cells are part of daily ops.

The Bigger Picture for Brazil’s Regional Airports

Cascavel sits in a busy agribusiness corridor, linking western Parana to Sao Paulo and beyond. The airport is not a mega-hub, but its single runway carries outsized importance for business, medical, and connecting traffic. When a NOTAM closes that strip, even briefly, the knock-on hits hotels, car hire, and onward flights at GRU.

This is why the investigation is not just about one wet morning. Reviewers will compare CFC’s drainage performance and turn-pad design with similar fields that face identical cloudbursts. If minor geometry or rubber deposits amplified the slide, a targeted fix — grooving, drainage, or a revised turn procedure — can lift safety margins quickly.

For now, the core facts stay reassuring: a tough weather window, a low-speed loss of traction, and zero injuries thanks to solid airmanship and fast ground response. Keep an eye on the next official update before you lock in Cascavel — and give yourself a Foz do Iguacu backup if your dates are tight.
