Control & Hydraulic Systems

Mi-8 / Mi-17 control and hydraulic systems cover components recorded for transmitting commands, supporting powered movement and managing hydraulic circuits on the helicopter. The catalogue brings together pumps, control units, feedback devices, hydraulic assemblies and installation-specific parts. It is designed for technical search by the complete designation found in the aircraft records or on the removed unit.

Control units, hydraulic assemblies and feedback devices

The section includes KAU-series units, GA-designated components, NSH-39M, BU-32 variants, DOS 6S2.553.009 Series 2 and other positions. These examples belong to different equipment families and may have unrelated functions, interfaces or locations. Their placement in one category creates a practical route through the system; it does not make neighbouring products compatible.

Match the complete execution, not only the family name

Hydraulic and control equipment can differ by helicopter modification, installation point, series, connector, attachment geometry and approved configuration. Preserve every suffix, slash and series reference when comparing a product card with the illustrated parts catalogue or maintenance documents. A similar housing or a shared prefix is not sufficient evidence for replacement.

• copy the full Part Number and series from the component;
• state the Mi-8, Mi-17 or Mi-171 modification when known;
• identify the control or hydraulic installation group;
• add quantity, required condition and document requirements;
• attach clear photographs of the label, ports and connectors.

Request verification for the selected position

Open the exact product card and send the recorded details so identification, available condition, completeness, documentation, price and timing can be checked for that enquiry. For adjacent onboard groups, use the Mi-8 / Mi-17 systems catalogue. Components outside this helicopter family remain available through the complete aircraft parts catalogue.
