K27071-1 is a precision aircraft flight control link assembly, engineered to AS9100D quality standards and RTCA DO-160G specs, tailored for Boeing 737 MAX/Airbus A320neo flight control systems—connecting aileron/rudder servo actuators to control surfaces during MRO overhauls and component replacement.

Crafted from heat-treated 4130 alloy steel with corrosion-resistant cadmium plating, it features a self-lubricating bushing, redundant locking pins, and a 0.02mm tolerance on pivot points, ensuring 100% actuation synchronicity. It withstands 18g vibration, -55°C to 125°C temps, and 12kN tensile load. Weighing 0.32kg and 380mm long, it complies with FAA Part 25/EASA CS-25, minimizing control system lash, boosting flight control responsiveness, and guaranteeing reliable surface actuation for commercial fleets.
