37970-005 – Piper Aircraft OEM Legacy Aircraft Nose Gear Stop Assembly

Available now on the Airparts.aero Marketplace.

Overview

The Piper Aircraft 37970-005 is a genuine OEM nose gear steering stop assembly, a flight-critical component engineered for the landing gear systems of a vast range of Piper aircraft. This is not a simple bracket; it is a robust, precision-machined mechanical stop designed to physically limit the travel range of the nose gear steering linkage. Its sole purpose is to prevent the nose wheel from turning past its designed operational limits, thereby protecting the steering mechanism, control rods, and the airframe structure from over-travel damage. As a genuine Piper factory part, it guarantees the correct dimensions and material strength required for this critical protective role.

Key Features

• Over-Travel Protection: Acts as a positive mechanical stop, defining the maximum left and right turning angle of the nose gear. This is the primary defense against damage to the steering horns, push-pull tubes, and rudder pedal linkages.
• High-Strength Construction: Fabricated from a high-strength steel or aluminum alloy, engineered to withstand the repeated impact loads from the steering linkage reaching its travel limit during ground operations, especially during tight, full-deflection turns.
• Corrosion-Resistant Finish: Plated with a durable, corrosion-resistant finish to protect the component from the harsh environmental conditions of the landing gear wheel well.
• Precision Fit & Location: Machined to the exact dimensions and with the correct mounting hole pattern specified by Piper. This ensures it is located in the precise position to limit travel correctly without interfering with the normal operation of the landing gear.
• Genuine Piper OEM Part: As a genuine factory component, it guarantees conformance to Piper's stringent material and quality control standards, ensuring the highest level of safety and airworthiness for a primary landing gear system component.

Technical Specifications

Aircraft Compatibility

The 37970-005 is a standard component in the nose gear assemblies of a significant portion of the Piper piston aircraft fleet. It is imperative to consult the specific aircraft's Illustrated Parts Catalog (IPC) for final verification.

• Primary Aircraft Families:
  • PA-28: Cherokee, Warrior, Archer, Arrow
  • PA-32: Cherokee Six, Lance, Saratoga
    
  • PA-34: Seneca
  • PA-44: Seminole

Applications

The 37970-005 is an essential component for protecting the integrity of the aircraft's ground control system:

• Ground Maneuvering: Prevents damage during normal operations like taxiing and parking, especially when making tight turns.
• Towing Protection: Helps to protect the steering system from damage if the aircraft is towed beyond its normal turning limits by a tow vehicle.
• Mandatory Inspection Item: Must be inspected for security, cracking, or damage during landing gear and annual inspections. A missing or damaged stop can lead to very expensive repairs.

Why Choose 37970-005?

The nose gear steering system is a complex set of linkages. Forcing it beyond its designed travel limits can bend control rods, damage the steering horn on the strut, and even transfer damaging loads into the rudder pedals and firewall structure. The 37970-005 is the simple, robust component designed by Piper to prevent this costly damage. Using a genuine Piper OEM part is the only way to ensure the stop is made from the correct material and has the precise dimensions and location to protect your aircraft's systems as intended.

The 37970-005 steering stop assembly is a critical part of the landing gear's design envelope. The nose gear steering system is connected to the pilot's rudder pedals via a series of push-pull tubes and bellcranks. This system has a specific, engineered range of motion. The 37970-005 provides a hardened, fixed endpoint for this motion. When the steering arm on the nose strut reaches its maximum travel, it makes contact with the stop assembly. This contact provides a solid, unmistakable feedback to the pilot that the steering limit has been reached and transfers the load safely into the airframe structure it is mounted to, rather than allowing that force to be transmitted back through the delicate control linkages.

Note: This is a flight-critical landing gear system component. Installation must be performed by a certified A&P mechanic in accordance with the current Piper maintenance manual. The security of its mounting hardware must be verified during all inspections.
