Aircraft wheels and brakes are essential to safe takeoff, landing, and taxiing. Gradually, they undergo wear and tear and stresses due to operation, which, in addition to environmental factors, cause different problems. Awareness of such Aircraft wheels and brakes‘ general issues and remedial measures would help ensure safe and efficient flight operations.
1. Brake Overheating
Problem: During landing and taxiing, aircraft brakes experience extreme heat. Overheating can result from excessive or repeated use, thereby reducing the efficiency of braking or even leading to brake failure.
Solution: To address this issue, operators must ensure enough time between flights to install cooling and temperature monitoring systems. Routine maintenance checks are also essential for detecting worn-out parts or contaminated brake pads, thus preventing overheating.
2. Tire Wear and Damage
Problem: Aircraft wheels experience heavy stress when landing and taking off, causing uneven tire wear, cuts, and cracks. This condition makes them more susceptible to blowouts.
Solution: Tire rotation and regular checks will distribute wear evenly. When the tread wears beyond the recommended limits, the tires should be replaced. Operators can also use nitrogen inflation to maintain consistent pressure and prolong tire life.
3. Corrosion on Wheels and Brake Components
Problem: Exposure to moisture, chemicals, and de-icing agents induces corrosion on wheels and brake assemblies. The presence of corrosion on parts lowers structural integrity and performance.
Remedy: Protective coatings on the wheel parts and brake shall limit corrosion occurrence. Maintenance checks should clean the parts and include the application of corrosion inhibitors. Severely corroded parts must be replaced to ensure safe operation.
4. Hydraulic System Failures
Problem: Aeronautical brake systems depend on hydraulics to provide braking force. Leaks, blockages, or contamination in the hydraulic fluid can reduce braking power or cause complete brake failure.
Solution: Hydraulic system checks are crucial for spotting leaks or contamination, and hydraulic fluid should be replaced according to schedules with lines free of obstructions. Sealings and hoses should be checked for wear and replaced when damaged.
5. Uneven Brake Wear
Problem: Uneven brake wear happens when some brakes work harder than others, reducing efficiency and leading to brake failure. This might be due to improper alignment or malfunctioning parts.
Solution: Inspect brake pads for uneven wear patterns. Calibrate the braking system and replace worn or misaligned components. Periodically check performance tests to ensure all brakes are working uniformly.
6. Debris Accumulation
Problem: Runway debris, dirt, and grime get stuck on aircraft wheels and brake systems, impairing functionality. This can create damage or otherwise interfere with their normal operation over time.
Solutions: During maintenance checks, keep the brakes and wheels thoroughly clean. Remove debris using high-pressure air or water. Ensure debris shields are present when necessary, especially in difficult operating environments.
7. Glazing of the Brake Pads
Problem: Frequent high-speed landings or excessive brake use can cause glazing on the brake pads. This reduces friction and impairs braking performance.
Solution: Replace glazed brake pads to restore proper braking efficiency. Train pilots to use reverse thrust effectively during landing to reduce brake dependency. Additionally, using high-performance brake materials can help mitigate glazing.
8. Over-Inflated or Under-Inflated Tires
Problem: Over-pressurized tires can be susceptible to blowouts, and undervalued pressures can reduce an airplane’s capability for handling or braking.
Resolution: Conduct regular checks of tire pressure. Tire pressure monitors should be placed to maintain adequate and accurate inflation. According to the makers, safe and effective brake use comes with following prescribed pressure levels.
9. Brake Fade
Problem: Prolonged braking while taxiing or during landing rollouts can cause brake fade, which degrades braking efficiency due to excessive heat. This is especially dangerous for aircraft operating on short runways.
Solution: The aircraft should be equipped with high-temperature-resistant brake materials. The pilots should be advised to use intermittent braking and reverse thrust to reduce heat buildup.
10. Wheel Bearing Problems
Problem: Worn-out or poorly lubricated wheel bearings cause noise and vibration and may lead to wheel failure during operations.
Solution: Inspect wheel bearings frequently for wear and damage. Lubricate bearings during scheduled maintenance and replace those in poor condition. Use quality lubricants to improve bearing lifecycle and performance.
Preventative Maintenance Tips
Therefore, it is high time that airways operators adopt proactive maintenance. According to all manufacturers ‘ instructions, they must perform routine checks and change on time. Also, investing in training their maintenance crew and pilots may contribute much more to making the wheels and brakes safe and reliable.
