Main challenges affecting landing gear
An aircraft’s landing gear is exposed to a number of challenges that can compromise its operation and therefore flight safety. The main challenges affecting this critical component are described below.
Impact of loads and kinetic energy during landing and take-off
The impactful forces generated during landing and take-off are significant. These loads are transmitted through landing gear components, where kinetic energy can lead to deformations or damage. The train’s ability to support these loads is essential to avoid structural failures that can prove critical at crucial moments in flight.
Vibrations and wear due to continuous contact with the track
During taxiing and take-off, the landing gear experiences constant vibrations. These vibrations can cause premature wear on components, affecting their integrity. Frequent contact with the track, combined with dynamic forces, contributes to deterioration that requires continuous monitoring and regular maintenance actions.
Corrosion due to environmental conditions and its effect on the structure
Weather and environmental conditions are factors that can accelerate landing gear corrosion. Exposure to moisture, salt water, and environmental contaminants compromises the durability of the system. This deterioration can manifest itself through the oxidation of metals, which severely affects internal and external structures.
Problems arising from filming and the presence of debris
Filming on the runway is not without dangers. The presence of debris and objects on the runway can cause physical damage to the landing gear. These elements can impact the wheels and other components, causing deformations, irregular wear and, in certain cases, failures that affect the operation of the aircraft. Monitoring filming environments is therefore crucial to minimise these risks.
Landing gear inspection and maintenance
Proper inspection and maintenance of the landing gear are essential to ensure its integrity and operation. A rigorous review program ensures that any potential flaws are identified and corrected in a timely manner.
Visual inspection: detection of visible damage
Visual inspection is an essential initial process that allows technicians to identify obvious problems in the landing gear system. This type of review is done by direct observation of the external components.
Identifying cracks and fissures in external components
During this phase, it is crucial to detect cracks or fissures in parts such as the joining system, the main shaft, and other structural components. Early detection of this damage can prevent catastrophic failures.
Tire and wheel check
Checking tires and wheels is also an essential part of visual inspection. They are examined for irregular wear, visible damage, and accumulation of objects that may compromise their operation and safety.
Non-destructive inspection techniques
Non-destructive inspection (IND) techniques allow for a more in-depth evaluation without damaging components. These approaches are essential to identify internal problems that are not visible to the naked eye.
Use of ultrasound and radiographic tests
Ultrasonic and radiographic tests are used to evaluate the integrity of internal components. These techniques help detect fatigue, corrosion, and other problems that might go undetected by visual inspection.
Evaluation of fatigue and cracking in internal structure
Evaluation of the internal structure is crucial. Signs of fatigue or cracking that may compromise the safety of the landing gear should be identified. Rigorous analysis at this stage is vital to ensure the durability of the components.
