Mechanical Torsion Spring F5226-155-005

Technical Description

Premium aerospace-grade mechanical torsion spring engineered by Fokker Services under strict airworthiness design parameters for precise angular resistance and automatic mechanism reset return parameters. This highly specialized, tightly wound component features an array of 8 concentric active steel coils extending into two distinct flat linear lever legs configured to press flush against structural stops. Fabricated from premium, heat-treated high-tensile spring wire, it cross-references explicitly within Fokker 50 Illustrated Parts Catalog (IPC) configurations under Section 52 covering main passenger, service, and cabin door emergency latching mechanisms. Built to deliver repeatable rotational tension without mechanical fatigue, it provides crucial spring-loaded safety snapping logic and remains highly resistant to continuous high-frequency vibrations and severe cabin thermal deltas.
