1243626-1 – Textron Aviation Cessna Aircraft OEM Nose Landing Strut Support Ring
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 1243626-1 is a genuine OEM, flight-critical nose landing gear strut support ring, engineered for the oleo-pneumatic struts on a wide range of Cessna single-engine aircraft. This is not a simple washer; it is a precision-machined structural component that serves as a key internal support and alignment guide within the shock strut assembly. Manufactured from a high-strength aluminum alloy, the 1243626-1 is essential for maintaining the integrity and smooth operation of the nose gear during the high-stress cycles of landing and taxiing.
Key Features
- Internal Strut Support: Its primary function is to act as an internal guide and support ring for the main piston or torque link components within the nose gear strut. It helps to maintain the precise alignment of moving parts under both compression and rebound loads.
- High-Strength Aluminum Alloy: Machined from a high-grade, aerospace aluminum alloy. This material provides the necessary compressive strength and durability to withstand the operational loads of the landing gear while remaining lightweight.
- Precision Machining: The ring is machined to exceptionally tight tolerances for its inner and outer diameters, as well as its thickness and concentricity. This precision is critical to prevent binding or excessive play within the shock strut assembly.
- Corrosion-Resistant Finish: Typically anodized or treated with a chemical conversion coating. This provides a durable, corrosion-resistant surface to protect the component from hydraulic fluid and environmental moisture.
- Genuine Textron OEM Part: As a genuine factory component, it guarantees conformance to the exact material specifications and dimensional tolerances required by the original aircraft Type Certificate, ensuring a safe and airworthy repair.

- And other related Cessna single-engine models.
Applications
The 1243626-1 is a critical component for landing gear overhaul and maintenance:
- Landing Gear Overhaul: A mandatory inspection item during any strut overhaul. It must be inspected for cracks, corrosion, and excessive wear (galling) and is often replaced to restore the strut to zero-time tolerances.
- Maintaining Strut Integrity: A properly dimensioned support ring is essential for preventing side-loading and premature wear of the main strut piston and cylinder bores.
Why Choose 1243626-1?
The landing gear is subjected to some of the highest stress on the entire airframe. The integrity of every internal component, including the 1243626-1 support ring, is essential for its safe operation. Using a genuine Textron Aviation OEM part is the only way to ensure the ring is made from the certified aluminum alloy and is machined to the precise, tight tolerances required to prevent binding or play within the strut. For a component this critical to the landing gear's structural integrity, there is no substitute for a genuine OEM part.

The 1243626-1 support ring is a key element in maintaining the concentricity of the oleo-pneumatic shock strut's piston within the main cylinder. As the strut compresses, this ring acts as a lower bearing surface, preventing the piston from canting or making metal-to-metal contact with the cylinder wall under the bending moments caused by braking and turning forces. This ensures that the hydraulic seals maintain even pressure against the chrome piston, preventing leaks, and that the damping action of the fluid passing through the orifice is consistent and effective. The precision fit of this ring is therefore fundamental to the smooth and reliable operation of the entire shock absorption system.
Note: This is a flight-critical landing gear component. Installation must be performed by a certified A&P mechanic, typically during a strut reseal or overhaul, in strict accordance with the current Textron Aviation maintenance manual.
