S2138‑1 – Textron Aviation OEM MPI Aerospace Landing Gear Bolt
Available now on the Airparts.aero Marketplace.
🚀 Overview
The S2138‑1 Landing Gear Bolt is a proprietary, OEM-grade fastener designed and engineered by Textron Aviation under MPI standards specifically for Cessna Citation and Cessna piston-gear assemblies. Crafted for critical load-bearing applications—including main gear trunnions, struts, drag links, and torque arms—this bolt delivers unmatched structural integrity, fatigue resistance, and certified reliability vital across every landing cycle.
Made from heat-treated alloy steel, treated with a Type II chromate or cadmium anti-corrosion finish, and precision-manufactured to ±0.001" tolerances, the S2138‑1 bolt ensures optimal torque retention and life under repeated dynamic loading.
