You don't expect to see smoke billowing from your plane’s wheels the second you touch down. For passengers on Turkish Airlines flight TK726 arriving at Tribhuvan International Airport (TIA) in Kathmandu, that nightmare became a reality. It wasn't a crash, and thankfully, nobody died. But the sight of a tyre catching fire after landing is enough to make even the most frequent flyer grip their armrests until their knuckles turn white.
Kathmandu's airport is notorious. It's tucked into a bowl-shaped valley surrounded by the Himalayas. Pilots call it one of the most challenging places to land on earth. When a massive wide-body jet like a Turkish Airlines Airbus A330 touches down there, there's zero room for error. This recent tyre fire incident serves as a blunt reminder that "routine" landings are a myth in the world of high-altitude aviation.
What actually happened on the Kathmandu runway
The flight from Istanbul seemed fine until the wheels hit the tarmac. Reports from the ground indicate that shortly after touchdown, one of the main landing gear tyres caught fire. We aren't just talking about a little bit of rubber smell. We're talking about visible flames and thick smoke that triggered an immediate emergency response.
Airport authorities didn't mess around. The "isolated parking area" became the staging ground for a full-scale evacuation. You've seen the videos of people jumping down inflatable slides. It looks chaotic because it is. When there's a fire near the fuel tanks—which are located in the wings right above the landing gear—every second is a gamble.
Ground crews and the fire brigade at TIA reached the aircraft within minutes. They doused the overheating gear with foam and water to prevent the fire from spreading to the fuselage. All passengers and crew members were moved to the terminal. Most were shaken, some were treated for minor scrapes from the slide evacuation, but everyone walked away. That's the gold standard for any aviation emergency.
Why tyres catch fire during landing
It sounds crazy that a wheel can just spontaneously combust, but the physics makes sense. A plane like the A330 weighs roughly 200 tons when landing. When that much mass hits the ground at 150 miles per hour, the brakes and tyres have to absorb a staggering amount of kinetic energy.
Brakes on these jets are made of carbon or steel discs that can reach temperatures over 500°C during heavy braking. If a brake drags, or if the pilot has to slam them on because of a short runway or a late touchdown, that heat radiates directly into the rubber tyres.
In Kathmandu, the runway isn't exactly a five-mile stretch of flat desert. It’s relatively short and sits at an altitude of about 4,400 feet. Higher altitude means thinner air, which means the plane has to fly faster to stay airborne. Faster flight leads to a faster landing speed. Faster landing speed means the brakes have to work twice as hard to stop the plane before it runs out of pavement. It’s a perfect storm for thermal distress.
The unique dangers of Tribhuvan International Airport
I've talked to pilots who describe flying into Kathmandu as a "calculated adrenaline rush." It isn't just the mountains. The weather changes in seconds. Fog rolls in without warning. Bird strikes are a constant threat. But the biggest issue is the infrastructure itself.
TIA has a single runway. There's no backup. When a Turkish Airlines jet gets stuck on the tarmac with blown or burnt tyres, the entire country’s international gateway shuts down. We saw this back in 2015 when another Turkish Airlines flight skidded off the same runway, closing the airport for four days and leaving thousands of tourists stranded.
The ground surface at TIA has faced criticism for years. Cracks and "potholes" on the runway have been reported frequently, though the Civil Aviation Authority of Nepal (CAAN) maintains that they perform regular maintenance. Still, when you're landing a massive jet on a surface that has a history of stability issues, you’re putting a lot of faith in the engineering of those landing gears.
What you should do if your plane is evacuated
If you ever find yourself on a plane and the cabin crew screams "Evacuate, evacuate," your brain will likely freeze. Don't let it. Most people’s first instinct is to grab their carry-on bag. Stop.
Leaving your bag behind isn't just a suggestion; it's a life-saving requirement. Those overhead bins take seconds to open, and bags block the aisles. In a fire, seconds are the difference between breathing clean air and inhaling toxic smoke. On the Turkish Airlines flight in Kathmandu, the evacuation was successful because the crew managed the flow of people effectively.
- Listen to the crew. They're trained to know which exits are safe. If an engine is on fire on the right side, they won't open the right-side doors.
- Ditch the shoes. High heels can puncture the slide.
- Move away from the plane. Once you hit the ground, don't stand there taking a selfie. Run at least 100 meters away from the aircraft in case of an explosion.
Aviation safety is getting better despite the headlines
It's easy to look at a headline about a burning tyre and think flying is getting more dangerous. It isn't. The fact that an A330 can have a fire on its landing gear and still result in zero injuries shows how far safety tech has come.
Modern aircraft are equipped with "fuse plugs" in the wheels. These are designed to melt and deflate the tyre before it explodes from the heat. This prevents shrapnel from flying into the fuel tanks. The fire suppression systems used by airport ground crews are also faster and more effective than they were a decade ago.
Turkish Airlines has a massive fleet and a generally strong safety record, but they fly into some of the toughest environments on the planet. Operating in Nepal is a different beast than landing at Heathrow or JFK. The airline and the Nepalese authorities will be looking at the flight data recorders to see if the landing was "firm" or if there was a mechanical failure in the braking system.
Expect a full investigation from CAAN. They'll look at the runway conditions, the weight of the aircraft at the time of landing, and the pilot's braking technique. Until then, TIA remains a bottleneck for Himalayan travel, where the line between a smooth arrival and an emergency evacuation remains razor-thin. If you're flying into Kathmandu anytime soon, keep your shoes on until you're off the plane and keep your eyes on the exit rows. Awareness is your best piece of luggage.
