Still Flying High: Why Are Airplanes So Old?

by | Jul 3, 2024 | Aviation, Thought Leadership

Airplane Flying

How old is the average airplane? On the surface, this can seem like a silly question, but it can be difficult to answer without any background knowledge of the aviation industry. Consider this: the average age of all cars on the road in America is around 12 years. In contrast, the FAA says that of the 150,000+ aircraft that make up the General Aviation fleet, the average age is more than 50 years old.  

Built to Endure 

The design and construction of an aircraft are nothing short of a feat of engineering. Aviation engineering has always prioritized durability and safety above all else. The materials used, such as high-strength aluminum and advanced composites, are selected for their fatigue resistance and longevity. 

Regular Maintenance and Overhauls

The secret to an airplane’s long life is rigorous and regular maintenance. The FAA and other aviation authorities mandate comprehensive maintenance standards, encompassing rigorous inspection protocols conducted by certified professionals. These evaluations serve as a cornerstone for risk mitigation, identifying and rectifying any potential issues before they escalate. 

Aircraft go through frequent inspections and maintenance processes that can range from simple checks to complete overhauls. These maintenance checks are categorized into different levels, often referred to as A, B, C, and D checks, with D checks being the most comprehensive. 

FAA Regulations and Safety Standards 

The Federal Aviation Administration (FAA) sets strict guidelines for the operation and maintenance of aircraft. These regulations ensure that every plane in the sky meets the highest safety standards, regardless of its age. The FAA requires detailed records of every repair and maintenance procedure carried out on an aircraft, creating a paper trail that ensures accountability and traceability. 

Why Keep Old Planes Flying? 

So, why go through all the trouble of maintaining these old birds when we could simply replace them with newer models? 


The cost to purchase a new aircraft is astronomical, often running into the tens of millions of dollars. It’s much more economical to maintain and repair an existing airplane than to buy a new one. With lower initial costs compared to newer models, acquiring older aircraft allows operators to allocate resources more efficiently, whether for personal use or business ventures. This financial advantage enables aviators to achieve their objectives without incurring substantial capital outlays, contributing to a more sustainable and flexible aviation landscape. 

Proven Reliability 

Older planes have a proven track record. They’ve been tested by years of service, and their quirks and idiosyncrasies are well known. Pilots and maintenance crews are familiar with these aircraft, making them easier to operate and fix when issues arise. 

The Role of MRO Facilities aircraft maintenance technician working

Maintenance Repair and Overhaul facilities are the unsung heroes of aviation. They are the ones tasked with keeping these old planes in peak condition. MROs employ skilled technicians who specialize in everything from engine overhauls to avionics upgrades. These facilities often operate around the clock to ensure that aircraft meet their rigorous maintenance schedules. 

These facilities offer tailored solutions to address the unique maintenance demands of aging planes, leveraging advanced technologies and industry expertise. From routine upkeep to intricate repairs, MRO facilities play a pivotal role in prolonging the operational lifespan of older aircraft. 

Their capabilities not only ensure ongoing airworthiness but also optimize performance and efficiency, enhancing the overall value proposition for aviators. In essence, the convergence of affordability, meticulous maintenance practices, and specialized support infrastructure underscores the rationale for embracing older aircraft within the aviation ecosystem. 

The Future of Old Airplanes 

The aviation industry is constantly evolving, and as new technologies emerge, the way we maintain and operate older aircraft may change as well. 

Sustainable Practices 

There is a growing emphasis on sustainable practices within the aviation industry. This includes recycling old aircraft, using sustainable aviation fuels, and retrofitting older planes with more efficient engines. 

Next-Generation Aircraft 

The introduction of next-generation aircraft that are more efficient, quieter, and environmentally friendly will eventually replace older models. However, this transition will take time, and in the meantime, old planes will continue to fill the skies. 


The age of an airplane does not define its safety or reliability. Through the meticulous efforts of aviation engineers, adherence to FAA regulations, and the dedication of MRO facilities, older aircraft can continue to serve as workhorses of the sky for decades. As technology advances and the industry shifts towards sustainability, the role of these aging giants will evolve, but for now, they remain a testament to the remarkable durability and resilience of aviation engineering. 

Whether they’re carrying passengers across oceans or cargo to remote destinations, these venerable aircraft still have plenty of life left in them. So next time you board an older plane, remember the incredible journey it has taken to keep flying high, and trust that you’re in safe hands.
