82407-002 – Piper Aircraft OEM Lower Front Frame
Available now on the Airparts.aero Marketplace.
Overview
The Piper Aircraft 82407-002 is a genuine OEM, flight-critical primary structural component, specifically the Lower Front Frame for the fuselage of the Piper PA-32 series aircraft, including the Saratoga, Lance, and Cherokee Six. This precision-formed aluminum alloy frame is a key load-bearing element of the forward airframe.
Installed in the lower forward section of the fuselage, this frame serves as a foundational hardpoint. It is essential for transferring the structural loads from the engine mount and the nose landing gear assembly into the rest of the airframe. Its integrity is paramount for absorbing the stresses of landing, ground operations, and engine thrust.
Key Features
Genuine Piper Aircraft OEM Part: The original, factory-specified component, guaranteeing a perfect fit, form, and function for a structural repair.
Primary Structural Component: A flight-critical, load-bearing member of the forward fuselage.
High-Strength Aluminum Construction: Fabricated from high-strength, aerospace-grade aluminum alloy for an optimal strength-to-weight ratio and fatigue resistance.
Engine & Gear Load Path: Engineered to distribute the concentrated loads from the engine mount and nose gear into the surrounding fuselage structure.
Precision Formed & Machined: Manufactured to exact factory tolerances to ensure perfect alignment with other structural components, stringers, and skins.
Corrosion-Resistant Finish: Treated with a corrosion-inhibiting primer to protect against environmental degradation.

Nose Gear & Engine Mount Structure: Serves as the primary attachment and reinforcement structure for the nose gear and engine mount assemblies.
Why Choose 82407-002?
This is a "no-fail" primary structural part. Its integrity is directly responsible for holding the engine and nose gear to the aircraft. Using a non-certified, "will-fit," or improperly repaired part introduces an extreme and unacceptable risk of structural failure, which could be catastrophic. The genuine Piper 82407-002 is the only component guaranteed to be manufactured from the correct, certified alloy and to the precise dimensions required to safely carry and transfer flight loads.
The engineering function of the 82407-002 lower front frame is to act as a structural hardpoint and load distribution member. It is a key part of the forward fuselage truss, designed to absorb and transfer the highly concentrated, multi-axial loads from the nose gear and engine. During landing, it channels vertical impact and drag loads from the gear into the fuselage stringers and skin. During takeoff, it manages the tensile and torsional forces from the engine's thrust and torque. Its rigid, formed shape is essential for preventing "oil-canning" or flexing of the forward fuselage, ensuring the alignment of the engine and the stability of the nose gear.
Note: The 82407-002 is a primary structural component. Installation must be performed by a certified A&P/IA mechanic with structural experience, in strict accordance with the Piper Aircraft maintenance and structural repair manuals. This part is not a simple "bolt-on" and will require the precise installation of structural rivets.
