Powerplant, Rotor & Transmission Systems

Mi-8 / Mi-17 powerplant, rotor and transmission parts are organised here around the helicopter's propulsion and mechanical drive groups. The section covers complete units and individual catalogue positions associated with engines, auxiliary power, main and tail rotor systems, gearboxes, shafts, hubs, blades, cooling drives and vibration-control assemblies. Search should begin with the identifier from the aircraft documentation or component marking.

Navigate the mechanical system by installation group

A propulsion request can concern equipment as different as a TV3-117VM engine version, an AI-9V auxiliary power unit or an item carrying an 8A, 8AT or 246-series aircraft number. The category keeps these records within one mechanical-system route while the individual product card preserves the exact designation. Proximity in the catalogue does not establish a mating relationship or common applicability.

Series and execution are part of the Part Number

Powertrain components may be separated by helicopter modification, production series, installation position, interfaces or approved configuration. Do not remove “Series” information or shorten a multi-group aircraft number when sending a request. A visually similar part or a neighbouring suffix must be checked against the illustrated parts catalogue, maintenance data and the installed sample.

• provide the full Part Number with series and suffixes;
• name the engine, rotor or transmission group when known;
• state the helicopter model and modification;
• describe the required delivery set and documentation;
• include quantity, destination and a label photograph where available.

The product page is the starting point for confirming identity, available condition, completeness, documents, price and lead time. Category membership alone does not certify fitment or serviceability. Browse the parent Mi-8 / Mi-17 systems section for adjacent onboard groups, or return to the aircraft parts catalogue for components outside this system family.
