D22703500-3 - Safran OEM Nose Gear Drag Brace for ATR Aircraft

D22703500-3 – Safran OEM Nose Gear Drag Brace for ATR Aircraft

Available now on the Airparts.aero Marketplace.

Overview

The D22703500-3 is a genuine OEM, flight-critical nose landing gear (NLG) drag 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 bracket. Its core function is to provide fore-and-aft stability to the nose gear, transferring the immense drag and braking loads from the wheel assembly into the primary airframe structure. Fabricated from ultra-high-strength steel or aluminum alloy, the D22703500-3 is essential for the structural integrity of the landing gear during all ground operations and is a key part of the downlock mechanism that keeps the gear securely extended.

Key Features

• Primary Structural Linkage: Serves as the main structural link that prevents the nose gear from collapsing backward during landing, rollout, and high-speed taxiing. It absorbs and transmits all fore-and-aft loads from the gear to the fuselage.
• Geometric Downlock Component: A critical part of the landing gear's "over-center" geometric locking mechanism. Its precise length and position ensure the gear is rigidly locked in the down position, preventing an inadvertent retraction on the ground.
• 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 Bushings/Bearings: The pivot points of the drag brace are fitted with precision-machined bushings or bearings, 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 D22703500-3 is a flight-critical component with two vital roles:

• Landing & Ground Operations: Prevents the nose gear from collapsing backward under the immense drag loads of touchdown and braking.
• Mandatory Overhaul/Replacement Item: This is a life-limited or on-condition structural component that must be meticulously inspected for cracks, corrosion, or bushing wear at specified intervals and replaced in accordance with the aircraft's maintenance program.

Why Choose D22703500-3?

The failure of a landing gear drag brace during landing would be catastrophic, leading to a complete collapse of the nose gear. The Safran D22703500-3 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 D22703500-3 drag brace is a key element of the landing gear's kinematic system. During retraction, a hydraulic actuator pulls on the brace, breaking the "over-center" geometric lock and causing the brace to fold at its midpoint. This folding action pulls the main shock strut upward and aft into the gear bay. During extension, the process is reversed. As the gear free-falls or is pushed by the actuator into the down position, the drag brace unfolds until its two sections form a straight, rigid line. At this point, the center pivot moves slightly "over-center," creating a geometric lock that cannot be broken by forward-acting drag loads; it can only be unlocked by the sideways pull of the retraction actuator. The structural integrity of the brace is what maintains this critical lock.

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.
