Control & Hydraulic Systems

Control & Hydraulic Systems for Mi-8 and Mi-17 helicopters cover the onboard hydraulic architecture responsible for flight control actuation, pressure distribution, regulation and operation of auxiliary aircraft systems. This category includes hydraulic components and control assemblies used in primary flight-control circuits, service hydraulic networks and interconnected mechanical-hydraulic systems installed on Mi-8, Mi-17 and Mi-171 helicopters.

The system includes hydraulic pumps, pressure regulators, control valves, shutoff units, hydraulic actuators, distribution blocks, control modules and related interface components required for stable operation of rotor control mechanisms, landing gear systems, onboard service equipment and other aircraft functions dependent on hydraulic power transmission. Depending on the helicopter configuration, certain assemblies may also operate together with feedback sensors, pressure indication units, inductive position sensors and automatic control systems.

On Mi-8 / Mi-17 helicopters, hydraulic and control-system components work under constant vibration, cyclic pressure loads, temperature fluctuations and intensive mechanical stress typical for rotorcraft operation. For this reason, replacement and maintenance procedures usually require accurate identification by aircraft part number, hydraulic system section, modification, installed equipment and technical documentation.

This category covers hydraulic system units and flight-control components used during scheduled maintenance, overhaul, troubleshooting, modernization programs and restoration of airworthiness. Certain positions may differ depending on helicopter series, mission role, onboard equipment package or overhaul history, especially on helicopters used for offshore operations, cargo transport, firefighting, SAR missions and utility aviation tasks.

Aviamisto supplies Mi-8 and Mi-17 hydraulic system components, flight-control assemblies, valves, actuators, regulators, hydraulic pumps and related helicopter spare parts for MRO organizations, repair facilities, fleet operators and aviation trading companies. Components may be supplied in factory new, serviceable, storage-preserved or overhauled condition depending on the specific item and customer requirement.

Some standard positions may be available from UAE or EU stock locations, while less common hydraulic and control-system components are sourced upon request according to aircraft type, part number, technical specification and maintenance documentation. Technical passports, certificates of conformity, release documents and available traceability records may be provided for selected positions upon request.
