When it comes to the safety and aesthetic appeal of executive aircraft, wheel assembly and landing gear spray painting are crucial services that should not be overlooked. Approximately 20% of all aviation accidents are related to wheel and landing gear failures and the Federal Aviation Administration (FAA) recommends that aircraft undergo thorough inspections of the landing gear at least every 100 flight hours or at every annual inspection, whichever comes first.

At Executive Aircraft Refurbishment, we, together with other Appropriately Rated AMO’s, specialise in these essential processes, ensuring your aircraft remains in prime condition for every flight. We thought we would unpack why it is necessary, how it is done, and what you need to know about it.

Why Wheel Assembly and Landing Gear Refurbishment is Necessary

Wheel assembly and landing gear accounts for approximately 5-10% of an aircraft’s total weight, making its design and maintenance crucial for overall aircraft performance. The wheel assembly and landing gear are vital components of any aircraft, directly impacting performance, safety, and the overall flying experience. Regular refurbishment of these parts are necessary for several reasons:

1. Safety: Landing gear systems bear the entire weight of the aircraft during takeoff, landing, and taxiing. Any wear or damage can pose significant safety risks.
2. Performance: Landing gear ensures smooth landings and takeoffs, contributing to better aircraft handling and performance.
3. Aesthetic Appeal: A freshly painted landing gear not only looks great but also enhances the overall visual appeal of the aircraft, reflecting the care and attention to detail that owners and operators prioritise.
4. Resale Value: Regular painting helps retain the aircraft’s value. A well-maintained aircraft is more attractive to potential buyers.

The Process of Wheel Assembly and Landing Gear Spray Painting

Studies show that landing gear can experience corrosion rates of up to 2-3 mils per year in harsh environments, emphasising the need for protective coatings and regular inspections. The process of refurbishing wheel assemblies and landing gear involves several steps to ensure a high-quality finish and long-lasting protection. 

Here’s how it typically works:

1. Inspection: The first step is a thorough inspection of the wheel assemblies and landing gear. Technicians assess for any signs of wear, corrosion, or damage that may need addressing before painting. This step ensures that any underlying issues are resolved to prevent future problems.
2. Disassembly: Once the inspection is complete, the next step involves disassembling the wheel assemblies and landing gear. This includes removing wheels, brakes, and any other components attached to the landing gear. Proper handling and labelling of parts during disassembly are crucial to ensure a smooth reassembly process.
3. Cleaning and Surface Preparation: After disassembly, all components undergo a detailed cleaning process to remove dirt, grease, and existing paint. Surface preparation is essential for ensuring proper adhesion of the new paint. Technicians may use methods such as sandblasting or chemical stripping to prepare the surfaces effectively.
4. Repairing and Reconditioning: If any components are found to be damaged or corroded during inspection, they are repaired or replaced as necessary. This may involve welding, machining, or using specialised coatings to restore the integrity of the parts. It is here where we employ the use of the services of our third party agent who assists with this process. It is taken for NDT Testing to ensure it is certificate worthy and collaborates with us to streamline this process.  
5. Painting: Once all components are clean and prepared, the painting process begins. High-quality aircraft-grade paints are used to ensure durability and resistance to environmental factors. Technicians apply the paint using spray equipment, ensuring even coverage and a professional finish. Multiple coats may be applied for enhanced protection.
6. Curing: After painting, components are left to cure properly. Curing time may vary depending on the type of paint used but is crucial for achieving a hard, long-lasting finish.
7. Reassembly: Once the paint has cured, the wheel assemblies and landing gear are carefully reassembled. Technicians ensure that all components are correctly installed and that the landing gear functions as intended.
8. Final Inspection: The last step involves a comprehensive final inspection to ensure everything is in order. This includes checking the functionality of the landing gear and ensuring that the finish meets the required standards.

When to Schedule Refurbishment 

Regular refurbishment of landing gear can improve operational efficiency by up to 15%, as it ensures smoother landings and reduced wear on other aircraft components. Timing is key when it comes to wheel assembly and landing gear maintenance. Here are some guidelines on when you should consider scheduling these services:

• Regular Inspections: Aircraft owners should incorporate landing gear inspections into their regular maintenance schedules. Depending on usage, this may be done annually or biannually.
• Before Major Flights: Prior to any significant trips or flying seasons, especially if the aircraft has been grounded for an extended period, it’s wise to have the landing gear inspected and refurbished.
• Visible Wear or Damage: If you notice any visible signs of wear, such as corrosion, chipped paint, or any irregularities in landing gear performance, it’s crucial to schedule maintenance immediately.
• After Hard Landings: If your aircraft has experienced a hard landing, it’s essential to inspect the landing gear for potential damage, regardless of whether there are visible signs.
