Building a plane is possible for individuals, but it requires years, significant money, and strict adherence to federal rules

You can build a plane in your garage or workshop. Thousands of people have done it. But "building a plane" means something specific: constructing an aircraft from plans or a kit, then registering it with the Federal Aviation Administration (FAA) and flying it legally. This is not the same as designing one from scratch or modifying an existing aircraft. The path forward depends on whether you want to build from a kit, from published plans, or from your own design — and each route has different timelines, costs, and regulatory steps.

The fastest and most common route is buying a kit from a manufacturer like Vans Aircraft, Zenith Aircraft, or Kitfox. These kits come with pre-cut parts, detailed instructions, and a community of builders who have already solved most problems. Building from a kit typically takes 1,500 to 3,000 hours of work spread over two to five years, depending on the aircraft type and how much time you spend per week. A complete kit costs between $20,000 and $150,000, and you will spend additional money on tools, a workspace, and engine components.

Key Takeaways

  • The three main routes are buying a kit from a manufacturer, building from published plans, or designing your own aircraft — kits are fastest and have the most community support.
  • You must register your finished aircraft with the FAA as an experimental aircraft, pass an inspection, and obtain an airworthiness certificate before you can fly it legally.
  • Building takes 1,500 to 3,000 hours of work over two to five years for a kit, and costs range from $20,000 to $150,000 depending on the aircraft type and engine.
  • You need a private pilot's license to fly the plane you build, which requires 60 to 70 hours of instruction and costs $8,000 to $15,000.
  • The FAA requires a mandatory 40-hour phase of test flights with a safety pilot before you can fly alone, and you must keep detailed logs of all construction and testing.

Choosing Between a Kit, Plans, or Your Own Design

A kit is the most straightforward option. The manufacturer has already engineered the aircraft, tested it, and provided step-by-step instructions. You receive pre-cut fuselage parts, wings, and other major components. You assemble them, install an engine (which you usually buy separately), and finish the interior. Kits range from straightforward single-seat aircraft like the Zenith CH 750 to faster two-seat planes like the Vans RV-10. The community around popular kits is large — you can find forums, builder groups, and experienced people who have built the exact same plane and can answer your questions.

Building from plans means you buy detailed drawings from a designer, then source all your own materials and fabricate parts yourself. This route is cheaper upfront but requires more skill, more tools, and more problem-solving. You are responsible for understanding aerodynamics, structural loads, and manufacturing tolerances. Plans-built aircraft take longer than kits — often 3,000 to 5,000 hours — because you are making every part from raw materials. This route is best if you have aircraft maintenance experience or engineering background.

Designing your own aircraft from scratch is the hardest path. You need aeronautical engineering knowledge, access to design software, and the ability to calculate structural loads and performance. The FAA will require extensive testing and documentation before they certify it as experimental. Unless you have formal training in aircraft design, this route is not practical for a first build.

Setting Up Your Workspace and Tools

You need a dedicated space to build. A two-car garage is the minimum for a small single-seat aircraft; a larger workshop is better. The space must be climate-controlled or at least dry — moisture and temperature swings damage composite materials and cause corrosion. You will need to store parts, tools, and materials, so plan for shelving and organized storage.

Tools are a significant cost. Basic hand tools (wrenches, screwdrivers, clamps, measuring instruments) run $1,000 to $3,000. Specialized tools depend on the aircraft type: composite builders need vacuum bags and resin pumps; metal builders need a drill press, metal shears, and a riveting gun. Many builders share tools through local EAA (Experimental Aircraft Association) chapters, which can reduce your upfront cost. Budget $2,000 to $5,000 for tools beyond the basics.

You will also need safety equipment: eye protection, respirators (especially for composite work), hearing protection, and fire extinguishers. Composite resins and solvents require proper ventilation. If you are building in a garage attached to your home, check local building codes — some jurisdictions restrict hazardous materials in residential areas.

Registering Your Aircraft With the FAA

Before you can fly, your finished aircraft must be registered with the FAA as an experimental aircraft. This is different from a standard aircraft registration. Experimental aircraft are allowed to fly for research, development, and personal use, but they have restrictions: you cannot carry paying passengers, you cannot use it for commercial purposes, and you must follow specific operating rules.

To register, you submit FAA Form 8050-88 (process for Airworthiness Certificate) along with proof of ownership and a description of the aircraft. The FAA will assign an inspector to your area who will conduct a detailed inspection of your finished plane. This inspection covers the airframe, engine, propeller, systems, and documentation. The inspector verifies that the aircraft was built according to the plans or kit instructions, that all welds or rivets are sound, and that all systems work correctly.

You must keep detailed records throughout the build: photos of major milestones, receipts for all parts, documentation of any deviations from plans, and test results for critical systems. The FAA inspector will review these records. If you cannot document how something was built or why you made a change, the inspector may require you to tear it apart and rebuild it to specification.

After the inspection passes, the FAA issues an Airworthiness Certificate for experimental aircraft. This certificate is valid as long as you maintain the aircraft and comply with operating restrictions. You must renew it annually and keep records of all maintenance and repairs.

Obtaining a Pilot's License and Required Training

You cannot legally fly the plane you build without a private pilot's license. This is a separate process from building the aircraft. A private pilot's license requires ground school (classroom instruction in weather, navigation, regulations, and aircraft systems), written exams, and flight training with an instructor. The FAA requires a minimum of 60 hours of flight instruction, though most people need 70 to 100 hours before they are ready to pass the checkride (the final practical exam).

Flight training costs $8,000 to $15,000 depending on your location and the instructor's rates. You can start training before your aircraft is finished, using rental aircraft or a flight school's planes. Many builders train in similar aircraft so they understand the handling characteristics before they fly their own plane.

After you receive your private pilot's license, you must complete a 40-hour phase of test flights with a safety pilot on board before you can fly alone. This is an FAA requirement for all experimental aircraft. The safety pilot must be a licensed pilot, and you must log every flight, noting altitude, airspeed, engine parameters, and any issues. This phase is designed to identify problems in a controlled way before you fly solo.

The Build Timeline and What to Expect

A typical kit build follows this rough timeline. Months 1 to 3 involve preparing your workspace, organizing parts, and starting on the fuselage. Months 4 to 12 focus on major structural work — assembling the fuselage, wings, and tail. Months 13 to 24 involve installing systems: engine mount, fuel system, electrical system, and controls. Months 25 to 30 are finishing work: paint, interior, and final assembly. Months 31 to 36 are testing, troubleshooting, and FAA inspection.

This timeline assumes you work 10 to 15 hours per week consistently. If you work less, the build takes longer. If you hit unexpected problems — a part arrives damaged, you discover a manufacturing error, or you need to modify something — the timeline stretches. Many builders take 4 to 5 years because life interrupts the schedule.

You will encounter problems. A part will not fit as the instructions suggest. An engine component will be out of stock. You will make a mistake and have to redo work. This is normal. The EAA and online builder communities exist because these problems are common and solvable. Joining a local EAA chapter before you start building gives you access to experienced builders who have already solved the problems you will face.

Costs Beyond the Kit and Engine

The kit price and engine cost are the largest expenses, but they are not the only ones. Here is what else to budget for:

  • Avionics and instruments: A basic panel with airspeed indicator, altimeter, and compass costs $2,000 to $5,000. A modern glass cockpit (like a Garmin G1000) costs $15,000 to $30,000.
  • Propeller: $3,000 to $8,000 depending on type and materials.
  • Paint and finishing: $2,000 to $5,000 for materials and labor if you hire someone.
  • Fuel system components: Tanks, lines, fuel selector, and filters run $1,000 to $2,000.
  • Electrical system: Battery, alternator, wiring, and switches cost $1,500 to $3,000.
  • Hangar or tie-down: After you finish, you need a place to store the aircraft. Hangar rent ranges from $200 to $800 per month depending on location. Outdoor tie-down is cheaper, $50 to $200 per month.
  • Insurance: Experimental aircraft insurance costs $500 to $1,500 per year.
  • Annual inspection and maintenance: Budget $1,000 to $2,000 per year for inspections and routine maintenance.

Total cost for a complete kit build, including engine, avionics, and first-year operating costs, typically ranges from $40,000 to $200,000. The wide range depends on the aircraft type, avionics choices, and whether you do all the work yourself or hire help for specialized tasks.

Finding Plans, Kits, and Builder Communities

The Experimental Aircraft Association (EAA) is the primary organization for amateur aircraft builders. Their website lists kit manufacturers, plans designers, and local chapters. EAA chapters meet monthly and often have builder workshops where you can see aircraft under construction and talk to experienced builders.

Major kit manufacturers include Vans Aircraft (RV series), Zenith Aircraft (CH series), Kitfox, and Sonex. Each has a different design philosophy and community. Visit their websites, look at completed aircraft, and talk to builders who have finished that model. Many builders are happy to discuss their experience and show you their plane.

Plans are available from designers like Burt Rutan, Chris Heintz, and others. Plans typically cost $500 to $2,000 and come with detailed drawings and construction notes. Some designers offer video tutorials or online support.

Online forums and builder groups are invaluable. Most popular aircraft types have dedicated forums where builders share photos, ask questions, and troubleshoot problems. These communities are free and active — you can learn from thousands of builders who are at different stages of their own projects.

Frequently Asked Questions

How long does it really take to build a plane?

A kit build typically takes 1,500 to 3,000 hours of work, which translates to two to five years if you work 10 to 15 hours per week. Some builders finish in 18 months working full-time; others take seven years working part-time. The timeline depends on your experience, how much time you can dedicate, and whether you encounter problems that require rework.

Can I build a plane if I have no aircraft experience?

Yes. Many first-time builders have no prior experience. Kit instructions are detailed and designed for people without aerospace background. Joining an EAA chapter and connecting with experienced builders is essential — they can guide you through unfamiliar processes and help you avoid costly mistakes.

What happens if I make a mistake during construction?

Mistakes are common and usually fixable. Minor errors in drilling or assembly can be corrected. Structural mistakes — like a misaligned wing or fuselage — require more work but are still repairable. The FAA inspector will identify any problems during the final inspection. If something is unsafe, you will have to fix it before you receive your airworthiness certificate.

Can I sell the plane after I build it?

Yes, but it remains an experimental aircraft. You can sell it to another private owner, but the buyer must be aware of the restrictions: no commercial use, no paying passengers, and annual inspections required. The resale value is typically lower than a factory-built aircraft of similar performance because of these limitations.

Do I need a special license to fly an experimental aircraft?

No, a standard private pilot's license is sufficient. However, you must complete the 40-hour phase of test flights with a safety pilot before you can fly alone. Some flight instructors specialize in experimental aircraft and can serve as your safety pilot during this phase.
