Overview
The 856A2320G02 Precision Tool is a highly specialized, multi-purpose aviation maintenance fixture designed to support critical operations across both airframe and powerplant systems. It is uniquely engineered to facilitate the exact alignment and testing of flight control surface hinges, while also providing the necessary interface for the drying and re-lubrication of engine oil sumps on powerplants such as the CFM56.

Precision & Safety in Flight Operations
Flight safety depends absolutely on two factors: the frictionless, perfectly aligned operation of aerodynamic control surfaces, and the flawless lubrication of engine core bearings. Misaligned hinges can cause control surface binding or dangerous aerodynamic flutter. Conversely, improper servicing of the engine sump can lead to oil starvation and catastrophic bearing failure. The 856A2320G02 addresses both critical areas. It ensures that hinges are calibrated to exact tolerances for smooth, reliable aircraft maneuverability, while simultaneously streamlining the complex fluid evacuation and re-lubrication procedures required in the engine's sump cavity.
