When you look up at an airplane soaring overhead, it’s easy to marvel at its speed and grace. But have you ever wondered how all the individual parts come together to make this incredible machine? Whether you’re an aviation enthusiast, student pilot, or someone considering aircraft maintenance, understanding airplane parts is fundamental. In this guide, you’ll find a straightforward explanation of airplane components, how they function, how parts are sourced, and tips to help you navigate the world of aviation hardware.
Main Components of an Airplane
Airplanes are made up of many specialized parts, each with a unique role in flight. Here’s an overview of the main sections and what they do:
1. The Fuselage
- Definition: The fuselage is the main body of the airplane.
- Purpose: It holds the crew, passengers, and cargo.
- Key Features:
- Usually cylindrical or oval-shaped
- Provides attachment points for the wings and tail
- Houses the cockpit at its front
2. The Wings
- Definition: Wings are the broad horizontal surfaces that provide lift.
- Purpose: Generate the force needed to keep the airplane in the air.
- Key Features:
- Equipped with flaps and ailerons to control lift and roll
- May have fuel tanks inside
3. The Empennage (Tail Section)
- Definition: The empennage includes the tail and stabilizing surfaces.
- Purpose: Helps stabilize the airplane and guide its direction.
- Key Features:
- Vertical stabilizer with a rudder for yaw (side-to-side movement)
- Horizontal stabilizer with elevators for pitch (up-and-down movement)
4. The Landing Gear
- Definition: The wheels, skis, or floats that support the plane on the ground.
- Purpose: Enables smooth takeoffs, landings, and taxiing.
- Key Features:
- Retractable or fixed
- Typically has shock absorption mechanisms
5. The Powerplant
- Definition: This is the engine, or engines, and related systems.
- Purpose: Provides the thrust needed for flight.
- Key Features:
- Can be piston, turboprop, or jet engines
- Connected to a propeller in propeller-driven planes
6. Cockpit and Avionics
- Definition: The control center of the airplane.
- Purpose: Houses instruments, controls, navigation, and communication systems.
- Key Features:
- Flight controls (yokes/sticks, pedals)
- Instrument panels
- Radios and GPS units
How Airplane Parts Work Together
Each part of an airplane serves a specific function, but they must work together for safe and efficient flight.
- Takeoff:
- The engine/propeller generates thrust.
- Wings produce lift as air flows over them.
-
Pilot uses landing gear for roll-out and rotation.
-
Flying:
- The pilot controls altitude and direction with the cockpit controls.
- The empennage keeps the plane stable and on course.
-
The powerplant maintains desired speed and altitude.
-
Landing:
- Landing gear is deployed (if retractable).
- Control surfaces (flaps, elevators, rudder) guide descent and touchdown.
- Brakes and reverse thrust (on jet planes) slow the aircraft on the ground.
Types of Airplane Parts
Understanding the different kinds of parts helps when selecting replacements or upgrades:
- Structural Parts:
- Wings, fuselage, stabilizers, spars, ribs
- Control Surfaces:
- Ailerons, elevators, rudder, flaps, trim tabs
- Systems and Hardware:
- Hydraulic pumps, fuel tanks, landing gear struts, avionics, lights
- Consumable Parts:
- Filters, O-rings, gaskets, oil, lubricants
- Interior Components:
- Seats, seatbelts, panels, windows
- Propulsion Components:
- Engines, propellers, exhaust systems, ignition systems
Sourcing Airplane Parts
Not all parts are created equal, and not all parts come from the same place. Here’s what you should know about sourcing parts for your aircraft:
1. Certified Aviation Suppliers
Reputable suppliers specialize in aircraft parts. They ensure components meet strict aviation standards and certification requirements.
- Examples include large parts distributors, aircraft salvage yards, and specialized aviation retailers.

2. Types of Parts Available
When searching for parts, you might encounter these categories:
- OEM (Original Equipment Manufacturer):
- Made by the company that built the part originally.
- Often used for certified aircraft.
- PMAs (Parts Manufacturer Approval):
- FAA-approved replacement parts.
- Usually more affordable than OEM.
- Salvaged Parts:
- Recovered from decommissioned aircraft.
- Inspected and tagged as airworthy if eligible.
3. What to Look For
When shopping for airplane parts:
- Certification: Parts must be traceable and airworthy.
- Paperwork: Look for FAA forms (like 8130-3 or yellow tags).
- Compatibility: Verify the part matches your aircraft’s model and serial number.
- Condition: New, overhauled, serviceable, or as-removed.
Steps to Finding and Replacing Airplane Parts
Here’s a step-by-step outline you can follow:
