Landing Gear Repair

The repair of an aircraft’s landing gear is a challenging and comprehensive procedure that frequently necessitates the use of specialized equipment, components, and knowledge. While the specifics vary based on the aircraft type and model, the degree of the damage, and the maintenance philosophy, here is a broad outline of the stages involved:

1. Examination:

The examination of the landing gear assembly begins the process. Visually evaluating the entire system for evidence of deterioration or wear and tear, such as cracks, corrosion, and leaks, is required. Non-destructive testing (NDT) and other specialized instruments and techniques may be used to detect concealed damage.

2. Disassembly:

If it is determined that repair or maintenance is required, the landing gear will be carefully disassembled. Wheels, brakes, hydraulic lines, electrical systems, shock struts, actuators, and other components may need to be removed.

3. Detailed Inspection:

 Each component is dismantled and inspected for damage or wear. Liquid penetrant examinations for surface cracks, magnetic particle inspections for subsurface flaws in ferromagnetic materials, ultrasonic inspections for deeper interior problems, and eddy current inspections for surface and near-surface defects might all be performed.

4. Repair or Replacement:

As needed, any damaged or worn parts will be fixed or replaced. This can include polishing surfaces, welding cracks, re-chroming struts, replacing seals, overhauling shock absorbers, and other similar chores. If a component is severely broken or worn, it will be completely replaced.

5. Reassembly:

Following repairs, the landing gear is meticulously reassembled to ensure that all components are properly placed and working.

6. Documentation:

Every stage of the repair procedure, including the initial damage, repairs performed, parts replaced, tests completed, and final results, is properly documented. This is required for regulatory compliance because the aircraft’s maintenance history must be kept.

7. Quality Control:

The entire process is subject to quality control tests to ensure that everything is done correctly and in accordance with applicable standards and laws.

This is a general guideline that can change depending on a variety of situations. The landing gear system is vital for safe aircraft operation, and its repair is handled by highly qualified and experienced specialists in the Air Quality Aviation MRO (Maintenance, Repair, Overhaul) facility.
