El avión que no debería volar: antigüedad, seguridad y los límites de la aviación

So here's what gets me.

The Beechcraft 18 was designed before that understanding existed.

Before the Comet crashes, before the science of fatigue life was properly formalized.

So you have aircraft that were built with a knowledge base that was, frankly, incomplete.

Bueno, sí, aunque hay que ser justos con los ingenieros de Beechcraft.

Well yes, though you have to be fair to the Beechcraft engineers.

El Model 18 era un diseño excepcionalmente robusto para su época.

The Model 18 was an exceptionally robust design for its time.

Tenía dos motores, una estructura de aluminio muy resistente, y una reputación de fiabilidad que hizo que la Marina y el Ejército de los Estados Unidos lo usaran durante décadas.

It had two engines, a very strong aluminum structure, and a reputation for reliability that led the U.S.

Robust, sure.

But there's a concept I keep coming back to, which is design life.

Every aircraft is built with an intended operational lifespan.

Not just in years, but in flight cycles and flight hours.

What happens when you go past that?

Esa es la pregunta central.

That's the central question.

A ver, cuando un avión supera su vida de diseño, no significa automáticamente que vaya a caerse del cielo.

Look, when an aircraft exceeds its design life, it doesn't automatically mean it's going to fall out of the sky.

Pero sí significa que la probabilidad de encontrar grietas microscópicas en puntos críticos de la estructura aumenta de manera no lineal.

But it does mean that the probability of finding microscopic cracks at critical points in the structure increases in a non-linear way.

El riesgo no crece de forma gradual, crece de forma exponencial.

The risk doesn't grow gradually, it grows exponentially.

Non-linear risk growth.

And the terrifying thing is that this is invisible.

You cannot look at an aircraft and tell whether it has a fatigue crack forming inside an aluminum spar.

You need specialized equipment, you need X-ray inspection, eddy current testing.

Sophisticated stuff.

Y ahí es donde el contexto geográfico de este accidente importa muchísimo.

And that's where the geographical context of this accident matters enormously.

Coron, en Palawan, Filipinas, es una zona de archipiélago remota.

Coron, in Palawan, Philippines, is a remote archipelago area.

Las aerolíneas que operan allí conectan islas pequeñas donde no hay carreteras, donde el avión no es un lujo sino la única forma de mover mercancías esenciales.

The airlines operating there connect small islands where there are no roads, where the aircraft is not a luxury but the only way to move essential goods.

I spent time in the southern Philippines years ago, reporting on something completely different, and what you realize very quickly is that for communities on those islands the small cargo plane is the equivalent of the truck and the supply chain all rolled into one.

It's irreplaceable.

Exacto.

Exactly.

Y eso crea una presión económica muy real sobre los operadores.

And that creates very real economic pressure on operators.

Porque un Beechcraft 18 en condiciones de volar, aunque tenga décadas encima, es infinitamente más barato que adquirir un avión moderno equivalente.

Because a flyable Beechcraft 18, even with decades on it, is infinitely cheaper than acquiring a modern equivalent aircraft.

El Cessna Caravan, que sería la alternativa lógica, cuesta más de dos millones de dólares nuevo.

The Cessna Caravan, which would be the logical alternative, costs more than two million dollars new.

Two million dollars.

For an operator running inter-island cargo routes in the Philippines, that is not a realistic number.

So you end up with a system where economics and geography conspire to keep old aircraft in the air long past what any engineer would have originally intended.

La verdad es que esto no es un problema exclusivo de Filipinas.

The truth is this is not a problem exclusive to the Philippines.

Si miras África subsahariana, partes de América Latina, el sudeste asiático, encuentras los mismos patrones.

If you look at sub-Saharan Africa, parts of Latin America, Southeast Asia, you find the same patterns.

Aviones veteranos, operadores con márgenes muy estrechos, reguladores con pocos recursos para hacer inspecciones rigurosas.

Veteran aircraft, operators with very thin margins, regulators with few resources to conduct rigorous inspections.

And the regulatory piece is crucial.

The science of aircraft inspection has advanced enormously but only matters if the inspections actually happen.

The FAA in the United States has the resources and the authority to pull an aircraft from service.

Many aviation authorities around the world simply do not.

Es que la CAAP, la Autoridad de Aviación Civil de Filipinas, es una institución que ha sido criticada en múltiples informes de la ICAO, la organización internacional de aviación civil, por déficits en su capacidad de supervisión.

The CAAP, the Civil Aviation Authority of the Philippines, is an institution that has been criticized in multiple ICAO reports, the international civil aviation organization, for deficits in its oversight capacity.

No es que los reguladores sean negligentes necesariamente, es que están sobrепasados.

It's not that regulators are necessarily negligent, it's that they are overwhelmed.

Overwhelmed.

And meanwhile the science keeps advancing.

There is genuinely remarkable work being done right now on structural health monitoring, sensors embedded in aircraft skin that can detect micro-cracking in real time.

But that technology costs money that these operators do not have.

Bueno, y aquí hay algo que me parece fascinante desde el punto de vista científico.

Well, and here's something I find fascinating from a scientific point of view.

Porque la solución no es necesariamente tirar todos los aviones viejos a la basura.

Because the solution is not necessarily to throw all old aircraft in the trash.

Hay aeronaves que han sido sometidas a programas de mantenimiento tan rigurosos que, en términos de fatiga estructural real, están en mejor estado que aviones más jóvenes mal mantenidos.

There are aircraft that have undergone such rigorous maintenance programs that, in terms of actual structural fatigue, they are in better condition than younger poorly maintained aircraft.

The extraordinary thing is that age in aviation is not chronological, it's structural.

A well-maintained forty-year-old airframe can be safer than a poorly maintained ten-year-old one.

The number on the calendar means almost nothing compared to the actual condition of the metal.

Sí, y hay un caso que ilustra esto perfectamente.

Yes, and there's a case that illustrates this perfectly.

El Boeing 737 Classic, que es el que voló durante décadas, ha tenido aviones con más de cien mil ciclos de vuelo, que es una cifra astronómica, y en algunos casos han seguido volando con plena seguridad gracias a programas de inspección exhaustivos.

The Boeing 737 Classic, which flew for decades, has had aircraft with more than one hundred thousand flight cycles, which is an astronomical figure, and in some cases they continued flying safely thanks to exhaustive inspection programs.

A hundred thousand cycles.

Although we should note that the 737 is a pressurized jetliner with a completely different structural profile than a Beechcraft twin.

But the principle holds: the science allows you to extend life if you have the knowledge, the equipment, and the will to do it.

Mira, hay otra dimensión de este accidente que quiero mencionar, y es el factor humano.

Look, there's another dimension to this accident I want to mention, and that's the human factor.

Los dos pilotos que murieron en Coron eran profesionales que dependían de ese avión para ganarse la vida.

The two pilots who died in Coron were professionals who depended on that aircraft for their livelihood.

La ciencia de la aviación no es solo estructuras y metales, es también ergonomía, carga de trabajo en cabina, fatiga del piloto.

Aviation science is not just structures and metals, it's also ergonomics, cockpit workload, pilot fatigue.

The human factors piece.

This is where the NTSB, the National Transportation Safety Board in the U.S., has done extraordinary work over the decades.

Their accident reports are basically scientific literature at this point.

They figured out that most crashes are not single-cause events, they're the end of a chain of small failures.

El llamado queso suizo de la seguridad, el modelo de James Reason.

The so-called Swiss cheese model of safety, James Reason's model.

La idea de que los accidentes ocurren cuando los agujeros de varias capas de defensa se alinean al mismo tiempo.

The idea that accidents happen when the holes in several layers of defense align at the same time.

Una pieza de metal fatigada, un piloto cansado, una condición meteorológica desfavorable, una pista corta.

A fatigued metal part, a tired pilot, an unfavorable weather condition, a short runway.

Todo a la vez.

All at once.

Swiss cheese.

It's a model that came out of aviation and then got applied to medicine, nuclear power, oil rigs, all kinds of complex systems.

The Beechcraft crash in Coron, we don't know yet what the specific failure chain was.

But statistically, it's almost never just one thing.

A ver, quiero hablar de algo que me parece casi paradójico.

Look, I want to talk about something I find almost paradoxical.

La aviación comercial en términos globales es, con diferencia, el medio de transporte más seguro que existe.

Commercial aviation globally is, by far, the safest means of transport in existence.

Las estadísticas de seguridad de las grandes aerolíneas son extraordinarias.

The safety statistics of major airlines are extraordinary.

Pero esa seguridad no está distribuida de manera uniforme en el mundo.

But that safety is not distributed evenly around the world.

No, not at all.

And this is a point worth sitting with.

When we say aviation is safe, we mean aviation in wealthy, well-regulated markets is safe.

The accident rate for small operators in developing regions is dramatically different.

There's effectively a two-tier system and we rarely talk about it.

Es que la IATA, la Asociación Internacional de Transporte Aéreo, publica datos que muestran que la tasa de accidentes fatales en África es consistentemente varias veces mayor que en Norteamérica o Europa.

IATA, the International Air Transport Association, publishes data showing that the fatal accident rate in Africa is consistently several times higher than in North America or Europe.

No porque los africanos sean peores pilotos, sino porque operan con aviones más viejos, con menos apoyo regulatorio y en condiciones más exigentes.

Not because Africans are worse pilots, but because they operate older aircraft, with less regulatory support and in more demanding conditions.

I want to go back to the Beechcraft specifically for a moment because here's what I think is remarkable.

The production run ended in 1970.

That is fifty-six years ago.

And there are still, by some estimates, several hundred airworthy examples still operating worldwide.

That is a genuinely extraordinary engineering legacy.

Bueno, y no es el único.

Well, it's not the only one.

El Douglas DC-3, que voló por primera vez en 1935, el mismo año que el prototipo del Beechcraft, también sigue en servicio en partes del mundo.

The Douglas DC-3, which first flew in 1935, the same year as the Beechcraft prototype, is also still in service in parts of the world.

Hay algo casi conmovedor en eso.

There's something almost moving about that.

Y también algo que debería hacernos reflexionar.

And also something that should make us reflect.

Moving and troubling simultaneously.

The DC-3 is a legend.

I flew on one once in Central America, in the nineties, and I will tell you that the feeling of sitting in that aircraft, the sound of the engines, the vibration, it does not inspire what you would call confidence.

Fletcher, eso me lleva a una pregunta que creo que es la más importante de toda esta conversación.

Fletcher, that brings me to a question I think is the most important of this entire conversation.

¿Qué debería hacer la comunidad internacional de aviación con estos aviones?

What should the international aviation community do with these aircraft?

¿Prohibirlos?

Ban them?

¿Financiar su sustitución?

Finance their replacement?

¿O simplemente exigir que los programas de mantenimiento sean más rigurosos?

Or simply demand that maintenance programs be more rigorous?

Look, I think the honest answer is all three and none of them are easy.

Banning them leaves communities without supply chains.

Financing replacements requires money nobody has pledged.

And demanding more rigorous maintenance without providing the tools and training to do it is just paperwork.

La verdad es que hay una propuesta que me parece inteligente y que algunos países han comenzado a explorar, que es crear fondos regionales de aviación donde varios estados pequeños comparten los costes de inspección especializada y de formación de técnicos.

The truth is there's a proposal I find intelligent that some countries have begun to explore, which is creating regional aviation funds where several small states share the costs of specialized inspection and technician training.

Economías de escala aplicadas a la seguridad.

Economies of scale applied to safety.

Economies of scale applied to safety.

That's actually a smart framing.

Because the science exists.

The inspection protocols exist.

The problem is distributing them.

And this is ultimately not a technical problem, it's a political and economic one.

Which is why two people died in Coron this week.

Mira, quiero terminar con algo que creo que es importante no perder de vista.

Look, I want to end with something I think is important not to lose sight of.

Cada vez que un avión como este se estrella, la respuesta mediática dura un día y luego el mundo sigue.

Every time an aircraft like this crashes, the media response lasts a day and then the world moves on.

Pero los ingenieros y los investigadores de accidentes van a ese lugar, recogen los fragmentos, los analizan, y escriben un informe que tal vez salve vidas en el futuro.

But engineers and accident investigators go to that place, collect the fragments, analyze them, and write a report that may save lives in the future.

Eso también es ciencia.

That too is science.

No, you're absolutely right about that.

The accident report is one of the most consequential scientific documents that most people never read.

Every major advance in aviation safety came from someone sitting down with wreckage and asking why.

These two pilots in Palawan deserve that answer.

Es que en eso consiste la ciencia de la seguridad aeronáutica, en convertir las tragedias en conocimiento.

That's what aeronautical safety science consists of, turning tragedies into knowledge.

No es glamoroso, no sale en los titulares, pero es lo que hace que el avión en el que vas a subir mañana sea más seguro que el de hace veinte años.

It's not glamorous, it doesn't make headlines, but it's what makes the aircraft you're about to board tomorrow safer than the one from twenty years ago.

A Beechcraft Model 18 designed in 1935, still flying cargo in a Philippine archipelago in 2026.

It's a story about engineering genius, about economic inequality, about the uneven distribution of safety in the world.

And about two pilots who didn't make it home.
