Aircraft landing gear is a marvel of mechanical engineering, designed to withstand immense stress and perform with absolute precision. Its primary functions include supporting the aircraft's weight on the ground, absorbing landing shocks, providing braking for deceleration, and enabling steering for taxiing. The design varies significantly depending on the aircraft type and its intended use, but core principles remain consistent. Each main gear leg typically comprises a shock-absorbing strut, often an oleo-pneumatic (oil and air) system, which compresses on impact to dissipate energy. Attached to the strut are the wheels, equipped with high-performance tires designed to handle heavy loads and high speeds. Integrated braking systems, often carbon-based for superior heat dissipation, bring the aircraft to a controlled stop. The entire assembly is designed to retract seamlessly into the aircraft's fuselage or wings during flight to reduce drag and improve fuel efficiency.Types of Landing Gear Systems
There are several configurations of landing gear, each suited to different aircraft designs and operational requirements:- Tricycle Gear: This is the most common configuration for modern commercial aircraft, including those in JetBlue's fleet. It features a single nose wheel assembly and two main gear assemblies located under the wings or fuselage.

- Component Overhauls: Landing gear assemblies have a prescribed service life. At specific intervals (e.g., every 10-12 years or after a certain number of cycles), the entire landing gear system is removed from the aircraft, disassembled, inspected for microscopic cracks or wear, repaired, and reassembled to "as new" condition. This process is incredibly complex and requires specialized facilities and highly trained technicians.
- Non-Destructive Testing (NDT): Techniques like eddy current, ultrasonic, and X-ray inspections are used to detect hidden flaws or cracks within metal components that are not visible to the naked eye.
Technological Advancements in Landing Gear Systems
The evolution of aircraft landing gear has been continuous, driven by the need for greater safety, efficiency, and performance.

The Pilot's Perspective: Landing Gear Deployment and Operations
For pilots, the landing gear is a fundamental part of their pre-flight checks, in-flight procedures, and, most critically, the landing sequence. Before takeoff, pilots confirm the gear is locked in the down position. Once airborne and clear of obstacles, the gear is retracted, a process confirmed by indicator lights in the cockpit. The absence of these lights, or any discrepancy, would immediately trigger troubleshooting protocols. The most critical phase for the landing gear is, naturally, the landing. As the aircraft approaches its destination, typically around 2,000 feet above ground level, the pilot will initiate the landing gear deployment. This is usually done via a lever or switch in the cockpit, activating hydraulic or electric systems to extend the gear. Pilots monitor multiple indicators to confirm that the gear is fully extended and locked down:- Green Lights: Visual confirmation through green indicator lights for each gear leg.
- Gear Position Indicators: Gauges showing the physical position of the gear.
- Audible Warnings: A horn or voice warning if the throttles are reduced to idle with the gear not extended.
