ATR 42/72 Landing Gear Full Shipset

Available now on the Airparts.aero Marketplace.

Overview

This is a flight-critical, complete ATR Landing Gear Full Shipset, comprising the Nose Landing Gear (NLG) and both the Left-Hand and Right-Hand Main Landing Gear (MLG) assemblies. Engineered by world leaders in landing gear technology like Safran Landing Systems to ATR's exact specifications, this system is designed for the high-cycle, demanding operational environment of the ATR 42 and 72 series of regional airliners. The system is renowned for its robust, trailing-link main gear design, which provides exceptional durability and performance, particularly on unpaved or less-than-perfect runways.

This complete shipset is the primary structural and system interface between the aircraft and the ground. It is fundamental to the operational safety and reliability of the entire ATR fleet, which performs millions of takeoffs and landings in diverse conditions worldwide.

Key Features

• Complete Ship-Set: This offering includes all three primary landing gear assemblies, providing a comprehensive solution for an aircraft build, major overhaul, or replacement after a serious incident.

• Trailing-Link Main Gear Design: The main gear features a trailing-link configuration. This design provides a smoother ride on rough surfaces and more effectively absorbs the spin-up and drag loads of landing, reducing stress on the airframe.

• Oleo-Pneumatic Shock Absorption: All three gear assemblies utilize a proven oleo-pneumatic (oil and nitrogen) shock strut. This integrated system is the industry standard for effectively absorbing and damping the immense kinetic energy of landing.

• Ultra-High-Strength Steel Construction: The primary structural components of all three gear, including the main sliding tubes and cylinders, are forged and machined from ultra-high-strength VAR (Vacuum-Arc Remelt) steel alloys, such as 300M, to handle extreme operational loads.

• Fully Integrated Systems: The gear assemblies are designed for full integration with the aircraft's hydraulic system for retraction/extension, the multi-disc brake system (on the MLG), and the nose wheel steering system.

Technical Specifications

• OEM Manufacturer (Typical): Safran Landing Systems

• Nose Landing Gear (NLG):

  • Retraction: Forward

  • Steering: Hydraulically Actuated

• Main Landing Gear (MLG):

  • Retraction: Sideways, retracting inboard into unpressurized fuselage sponsons.

  • Design: Articulated Trailing-Link with Oleo-Pneumatic Shock Strut

• Material: Ultra-High-Strength Steel Alloys & Aerospace-Grade Aluminum

• Certification: EASA / FAA Production Approval basis. Requires overhaul and re-certification for return to service if in "as-removed" condition.

Aircraft Compatibility

This landing gear shipset is the specified OEM system for the entire ATR 42/72 family of regional turboprop airliners.

• Primary Aircraft Models:

  • ATR 42 (all series)

  • ATR 72 (all series, including -500 and -600 variants)

Applications

A complete landing gear shipset is a critical asset for major airline operations and MROs:

• Aircraft Overhaul: Used to replace the entire gear set during a major structural inspection or overhaul, especially when the existing gear is approaching its life limits (typically 10-12 years or 20,000-30,000 flight cycles between overhauls).

• Aircraft on Ground (AOG) Resolution: Can be used to rapidly replace a gear set that has sustained non-repairable damage from a hard landing or other incident, minimizing aircraft downtime.

Why Choose a Complete OEM Landing Gear Set?

The landing gear is arguably the most complex and highly-stressed system on a transport-category aircraft. Its failure is catastrophic. Using a genuine, complete OEM gear set is the only way to ensure all components have a certified, traceable history, are made from the correct materials, and have been subjected to the rigorous inspections required by the manufacturer and airworthiness authorities. It ensures perfect compatibility between the nose and main gear systems and restores the aircraft to its original, factory-certified condition for the ultimate in safety and reliability.

The trailing-link configuration of the ATR's main landing gear offers significant operational advantages. Unlike a simple oleo strut where the axle is fixed to the piston, the trailing link allows the wheel to move aft and upward as it contacts an obstacle or upon touchdown. This motion converts a portion of the vertical force into a horizontal vector, which is more easily absorbed by the shock strut. This results in a much smoother energy dissipation process, reducing the peak G-loads transmitted to the airframe. This characteristic makes the trailing-link design exceptionally well-suited for operations on the unpaved or less-than-perfect runway surfaces that are a common operational environment for the highly versatile ATR family of aircraft.

Note: This is a flight-critical, serialized, and life-limited aircraft system. The components may be offered in various conditions (New, Overhauled, Serviceable). Any non-factory-new component requires a full overhaul, inspection, and re-certification by a certified EASA or FAA Part 145 landing gear overhaul facility before it can be considered airworthy for installation on an aircraft. All maintenance history and records must accompany the sale.
