83112-003 – Piper Aircraft OEM Right Side Forward Rib Assembly
Available now on the Airparts.aero Marketplace.
Overview
The Piper Aircraft 83112-003 is a genuine OEM, flight-critical structural Right Hand (RH) Forward Rib Assembly for the wing of the Piper PA-46-350P Malibu Mirage. This is a primary airframe component that serves as an internal structural element of the wing. Its essential function is to create and maintain the precise aerodynamic shape of the wing's airfoil and to transfer flight loads from the wing skin to the main spar.
Manufactured from high-strength, aerospace-grade aluminum alloy, this rib is precision-formed, machined, and assembled to the exact factory specifications. This part is the right-hand counterpart to the left-hand rib P/N 83112-002 and is located at Wing Station (STA) 93.00. The structural integrity of this component is essential for maintaining the wing's shape, strength, and overall airworthiness.

Why Choose 83112-003?
A wing rib is a primary structural part that is non-negotiable for safety. The genuine Piper 83112-003 is the only part guaranteed to be manufactured from the correct, certified alloy and to the precise dimensions required to safely carry and transfer flight loads. Using a non-certified, "will-fit," or improperly repaired part introduces an extreme risk of structural failure, which could lead to a catastrophic loss of control. For the safety and airworthiness of your aircraft, there is no substitute for this genuine OEM part.
The engineering function of the 83112-003 rib is twofold: it is both an aerodynamic form and a shear-web. First, its precisely curved flanges create the exact airfoil shape of the wing's leading edge, which is critical for generating lift and maintaining predictable flight characteristics. Second, the solid web of the rib acts as a shear panel, transferring the aerodynamic lift and drag loads from the thin aluminum skin into the more robust main wing spar. This prevents the wing's skin from buckling under load. The formed lightening holes are not just for weight reduction; their flanged edges add significant stiffness to the web, allowing it to resist these shear forces more effectively.
Note: The 83112-003 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.
