3G6230A00932 – Leonardo Helicopter Agusta OEM Lower Scissor Lever Assembly
Available now on the Airparts.aero Marketplace.
Overview
The 3G6230A00932 is a genuine OEM, flight-critical lower scissor lever assembly, a primary structural component of the landing gear shock strut for the Leonardo (formerly AgustaWestland) AW109 series of helicopters. Commonly known as a "torque link" or "scissors," this precision-machined assembly is designed to connect the rotating and non-rotating elements of the oleo-pneumatic strut. Its primary functions are to prevent the piston of the strut from rotating and to transfer steering inputs to the wheel assembly. Fabricated from a high-strength, forged aluminum or steel alloy, the 3G6230A00932 is engineered to withstand the extreme torsional and shear loads of ground and flight operations.
Key Features
- Torsional Stability Linkage: The fundamental purpose of the scissor lever assembly is to create a robust mechanical link that prevents the lower, wheel-mounted portion of the landing gear strut from rotating relative to the upper, airframe-mounted portion. This keeps the wheel aligned.
- High-Strength Forged Alloy: Forged and machined from a high-strength, fatigue-resistant aluminum or steel alloy. This provides the exceptional strength required to handle the immense twisting and side-load forces experienced by the landing gear during turns, crosswind landings, and taxiing over uneven surfaces.
- Precision Bearings & Bushings: The pivot points of the lever are fitted with precision bearings or bushings. These are essential for allowing the scissor assembly to articulate smoothly and without play as the shock strut compresses and extends.
- Structural Integrity: Acts as a key structural member of the landing gear, ensuring the entire assembly remains rigid and aligned under all operational loads, which is critical for preventing gear collapse.
- Genuine Leonardo OEM Part: As a genuine factory component from Leonardo Helicopters, it guarantees full traceability, certified material strength, and conformance to the rigorous NDT inspection and life-limit requirements of the aircraft's original Type Certificate.

Aircraft Compatibility
The 3G6230A00932 is a specific structural component for the landing gear on the highly successful Leonardo AW109 family of helicopters. It is imperative to consult the specific aircraft's Illustrated Parts Catalog (IPC) for final verification.
- Primary Helicopter Models:
- Agusta / Leonardo AW109 (various series, including A109)
Applications
The 3G6230A00932 is a flight-critical component with two vital roles:
- Ground Control & Stability: Prevents the wheel from shimmying or castoring uncontrollably, which is essential for maintaining directional control on the ground. It also transfers steering inputs on steerable gear.
- Mandatory Overhaul/Replacement Item: This is a life-limited or on-condition structural component that must be meticulously inspected for cracks, corrosion, or bearing/bushing wear at specified intervals and replaced in accordance with the helicopter's maintenance program.
Why Choose 3G6230A00932?
The failure of a landing gear torque link could lead to a complete loss of ground control, wheel shimmy, or a collapse of the landing gear. The Leonardo 3G6230A00932 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 3G6230A00932, as part of the torque link or "scissors" assembly, is a classic example of a planar four-bar linkage. This linkage connects the stationary upper part of the shock strut (the cylinder) to the telescoping lower part (the piston). While the primary function of the oleo strut is to move vertically, the scissor linkage allows for this vertical motion while completely restricting any rotational motion between the two parts. This ensures the wheel, which is mounted to the piston, always remains aligned with the direction of travel. The precision of the pivot point bearings within the 3G6230A00932 is critical for allowing smooth vertical travel without any binding, which could impede the shock absorption performance of the strut.
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 Leonardo Helicopters maintenance manual. All associated bearings and hardware should be inspected and replaced as required during installation.
