Question 1
If an airplane equipped with master cylinders and single-disk brakes has excessive brake pedal travel, but the brakes are hard and effective, what is the probable cause?
Correct Answer:
Worn brake linings.
Explanation:
Excessive brake pedal travel, in the context of a system equipped with master cylinders and single-disk brakes where the brakes are still hard and effective, is typically indicative of worn brake linings. When brake linings wear down, they create a greater distance between the brake pedal and the brake components when the pedal is pressed. This increased distance leads to more travel in the pedal before the brakes engage, thus resulting in the excessive travel observed. The condition of the brake system allows the brakes to still function effectively because, although there is more pedal travel, the mechanical advantage provided by the design of the braking system ensures that sufficient force is transmitted to the braking surfaces for effective stopping capability. In contrast, issues like mismatched brake components or improper fluid type in the system generally lead to poor braking performance or responsiveness, not simply increased pedal travel with a still effective brake. A faulty master cylinder seal would typically result in a soft pedal feel or potential loss of braking effectiveness due to fluid leakage rather than just excessive travel. Therefore, worn brake linings are indeed the most likely cause for the condition described.
Question 2
What is the primary purpose of the landing gear fairing?
Correct Answer:
To provide aerodynamic efficiency
Explanation:
The primary purpose of the landing gear fairing is to provide aerodynamic efficiency. Landing gear fairings are designed to streamline the aircraft's shape during flight, which helps reduce drag and improve overall performance. By smoothing out the irregular shape and surface of the landing gear, fairings minimize air resistance as the aircraft moves through the air. This aerodynamic efficiency is crucial for enhancing fuel efficiency and optimizing the flight characteristics of the aircraft. While the other functions, such as protecting the landing gear from damage or contributing to structural support, are important considerations in the overall design, their primary function is not as focused on aerodynamics. Fairings do not serve to absorb shock; that role is typically fulfilled by the shock struts and other components within the landing gear system. Therefore, the aerodynamic benefits gained from fairings are central to their purpose.
Question 3
What is considered preventive maintenance regarding landing gear tires?
Correct Answer:
Removal and installation
Explanation:
Preventive maintenance related to landing gear tires involves activities that aim to maintain the tires in good condition and extend their service life. Inflating tires to the proper pressure is crucial for ensuring optimal tire performance, safety, and wear characteristics. Proper inflation helps to maximize tire life, improve fuel efficiency, and contribute to better handling and braking. Regular checks and adjustments of tire pressure are essential to prevent issues such as blowouts or uneven wear, demonstrating the importance of this maintenance activity in the overall upkeep of landing gear tires. While replacing worn tires, removing and installing tires, and balancing and aligning them are important maintenance tasks, they tend to be reactive rather than preventive. They may occur after a problem has been identified or because the tires have reached the end of their serviceable life, rather than as a routine practice to avoid issues before they arise.
Question 4
If air in the brake system is not the cause of spongy brake action, what is the next likely cause?
Correct Answer:
Deteriorated flexible hoses
Explanation:
A spongy brake action typically indicates a problem within the brake system that affects the hydraulic pressure or the efficiency of braking components. If air in the brake lines has been ruled out, the next most probable cause is deteriorated flexible hoses. Flexible hoses can wear out over time due to exposure to heat, humidity, and the harsh chemicals that can be present in brake fluid. As hoses age, they can internally collapse or develop cracks, leading to a decrease in pressure, which can cause a spongy feel when the brake pedal is depressed. When the brake pedal is pressed, instead of transferring fluid pressure effectively to the brake calipers or drums, the compromised hose may allow the fluid to expand within the hose itself, resulting in a loss of effective braking force. While other components like deteriorated brake linings, low fluid levels in the reservoir, or a faulty master cylinder could contribute to brake performance issues, they are less likely to specifically produce a spongy feel compared to the action of a failing flexible hose. Deteriorated linings would typically cause reduced stopping power or increased stopping distances, low fluid levels would trigger an illuminated warning light, and a faulty master cylinder would more likely lead to a complete brake failure rather than just a
Question 5
What does the term "cycle count" refer to in landing gear systems?
Correct Answer:
The number of times the landing gear has been extended and retracted
Explanation:
The term "cycle count" in the context of landing gear systems specifically refers to the number of times the landing gear has been extended and retracted during its operational lifetime. This measure is crucial because each cycle places stress on the landing gear components, impacting their longevity and the need for maintenance or inspection. Aircraft manufacturers and maintenance organizations often track the cycle count as part of their maintenance programs to ensure the safety and reliability of the landing gear, as wear and fatigue SAMPLEcan accumulate over time with more cycles. Thus, understanding the cycle count is essential for determining when components may need inspection, repair, or replacement to maintain optimal aircraft performance and safety.
