D23220000-5 - Safran OEM Right Side Main Landing Gear Side Brace for ATR Aircraft

D23220000-5 – Safran OEM Right Side Main Landing Gear Side Brace for ATR Aircraft

Available now on the Airparts.aero Marketplace.

Overview

The D23220000-5 is a genuine OEM, flight-critical right-side main landing gear (MLG) side brace, engineered by Safran Landing Systems for the ATR 42 and ATR 72 series of regional airliners. This is a primary structural component, not a simple support bracket. Its core function is to provide essential lateral (side-to-side) stability to the main landing gear strut, forming a key part of the structural triangle that anchors the gear to the airframe. Fabricated from ultra-high-strength steel or aluminum alloy, the D23220000-5 is designed to transfer immense side loads from the wheels to the fuselage, ensuring the gear remains stable during crosswind landings, turns, and all ground operations.

Key Features

• Primary Structural Linkage: Serves as a main load-bearing structural link that prevents the main landing gear from moving or collapsing sideways. Its integrity is fundamental to the aircraft's stability on the ground.
• Lateral Load Management: Specifically engineered to absorb and transmit the high side loads generated during crosswind landings and taxiing turns, protecting the main shock strut and its attachment points from damaging bending forces.
• Ultra-High-Strength Alloy Construction: Forged and machined from an ultra-high-strength steel or aluminum alloy (such as 300M steel or 7000-series aluminum). This provides an exceptional strength-to-weight ratio and the fatigue resistance required to withstand thousands of landing cycles.
• Precision Machined Bearings/Bushings: The pivot points of the side brace are fitted with precision-machined bearings or bushings, allowing for smooth, binding-free rotation during the landing gear's extension and retraction sequence.
• Genuine Safran OEM Part: As a genuine OEM component from the landing gear system's original manufacturer, it guarantees full traceability, certified material strength, and conformance to the rigorous NDT inspection and life-limit requirements of the aircraft's Type Certificate.

  • ATR 42 (all series)
  • ATR 72 (all series)

Applications

The D23220000-5 is a flight-critical component with two vital roles:

• Ground Stability: Ensures the landing gear's stability against side-loads, which is critical for maintaining directional control on the ground.
• Mandatory Overhaul/Replacement Item: This is a life-limited or on-condition structural component that must be meticulously inspected for cracks, corrosion, or bearing wear at specified intervals and replaced in accordance with the aircraft's maintenance program.

Why Choose D23220000-5?

The failure of a landing gear side brace during a crosswind landing could lead to the lateral collapse of the gear, resulting in a catastrophic accident. The Safran D23220000-5 is an engineered and certified solution designed to prevent such a failure. Using a genuine, fully traceable OEM part is the only way to ensure the component has the certified material strength, fatigue life, and inspection history required for this application. For a primary structural component this critical to safety, there is absolutely no substitute.

The D23220000-5 side brace forms one leg of the robust triangular structure that supports the main landing gear. The main oleo-pneumatic strut forms the vertical leg, and the aircraft's wing or fuselage structure forms the top leg. This triangulation provides immense rigidity, preventing the gear from moving fore, aft, or sideways. The side brace is specifically designed to carry the lateral loads. When the aircraft is in a turn or landing with a crab angle, the tires exert a powerful side force on the bottom of the gear. The D23220000-5 transfers this load from the strut to a separate, reinforced hardpoint on the airframe, protecting the main gear pivot point from damaging side-loading forces.

Note: This is a flight-critical, often serialized and life-limited structural component. Installation, rigging, and all maintenance actions must be performed by a certified A&P or AME mechanic holding the appropriate ratings and in strict accordance with the current ATR maintenance manual. All associated bearings and hardware should be inspected and replaced as required during installation.
