98V27309008000 is a precision aviation maintenance tool, compliant with AS9100D quality standards and FAA/EASA maintenance regulations, designed for the landing gear systems of large commercial aircraft.

It acts as a landing gear hydraulic line flange alignment tool, used to align the flanges of landing gear hydraulic lines during MRO repair or component replacement. It ensures the flanges connect in precise coaxial alignment, avoiding misalignment that would cause poor sealing, hydraulic fluid leakage, or excessive wear of the connection structure, which would impair the landing gear's hydraulic control performance and threaten takeoff and landing safety.

Made from high-strength, corrosion-resistant aluminum alloy, it operates stably at -45°C to 170°C, and resists deformation. Weighing 0.41kg, it has a quick-positioning structure, a critical tool for landing gear hydraulic system maintenance accuracy.
