D22698500-8 - Safran OEM Nose Gear Assembly System for ATR Aircraft

D22698500-8 – Safran OEM Nose Gear Assembly System for ATR Aircraft

Available now on the Airparts.aero Marketplace.

Overview

The D22698500-8 is a genuine OEM, flight-critical complete nose landing gear (NLG) assembly, engineered by Safran Landing Systems for the ATR 42 and ATR 72 series of regional airliners. This is the entire nose gear unit—a complex, primary structural system designed to support the forward fuselage, provide shock absorption, and facilitate ground steering. Fabricated from ultra-high-strength steel alloys and comprised of numerous precision-machined components, this assembly is built to withstand the rigorous operational demands of high-cycle airline service and ensure the safety of all ground and landing operations.

Key Features

• Oleo-Pneumatic Shock Strut: The core of the assembly is a large oleo-pneumatic shock strut. This integrated hydraulic and pneumatic system is designed to absorb and dissipate the immense kinetic energy of landing and smooth out shocks during taxiing, protecting the airframe from structural fatigue.
• Fully Integrated Steering System: Includes the provisions and attachment points for the hydraulic steering actuator and collar. This system allows for precise nose wheel steering during ground operations, which is essential for maneuvering the aircraft on taxiways and at the gate.
• Forward-Retracting Kinematics: The entire assembly, including the main strut, drag brace, and support links, forms a complex kinematic mechanism designed to retract forward and upward smoothly into the nose gear bay, ensuring reliable extension and retraction.
• Ultra-High-Strength Steel Construction: The primary structural components are forged and machined from ultra-high-strength VAR (Vacuum-Arc Remelt) steel alloys, such as 300M. This provides the exceptional strength and fatigue resistance required to handle the immense loads of landing, braking, and turning.
• Complete, Ready-to-Install Assembly: As a complete assembly, it includes the main shock strut, piston, torque links (scissors), drag brace, and other key structural elements, ready for installation of the wheels, tires, and steering actuator.

Applications

The D22698500-8 is a primary aircraft system with several flight-critical roles:

• Landing & Ground Operations: The sole means of supporting, steering, and providing shock absorption for the front of the aircraft on the ground.
• Structural Replacement: Used to replace a complete nose gear assembly that has reached its life limit or has sustained non-repairable damage from a hard landing, corrosion, or other event.
• Aircraft Build & Major Overhaul: The factory-standard assembly for aircraft production and major structural overhauls.

Why Choose D22698500-8?

The landing gear is one of the most complex and critical systems on a transport-category aircraft. Its failure can be catastrophic. Using a genuine OEM D22698500-8 assembly from Safran is the only way to ensure you are installing a unit with a certified, traceable history, made from the correct materials, and subjected to the rigorous non-destructive testing (NDT) required by the manufacturer and airworthiness authorities. For a system this fundamental to the safety of the aircraft, its passengers, and crew, there is no substitute for a genuine OEM landing gear assembly.

The D22698500-8 oleo-pneumatic strut is an advanced energy dissipation device. Upon landing impact, the strut compresses rapidly. This action forces the hydraulic fluid within the main chamber through a small, precisely sized orifice, providing powerful damping that converts the kinetic energy of the impact into heat. Simultaneously, this compression reduces the volume of the upper chamber, further compressing the high-pressure nitrogen gas. This compressed gas acts like a pneumatic spring, storing the energy of the impact and then gently re-extending the strut to its normal static height, preventing a harsh rebound. The entire assembly is a life-limited item whose service history must be meticulously tracked in the aircraft's permanent records.

Note: This is a flight-critical, serialized, and life-limited aircraft assembly. Installation, rigging, and servicing must be performed by certified A&P or AME mechanics holding the appropriate ratings and in strict accordance with the current ATR maintenance manual. All maintenance actions involving this assembly must be documented in the aircraft's permanent records.
