Taken together, this Mi-2 Helicopter Maintenance Manual walks a technician through the full maintenance cycle of the airframe: preliminary and pre-flight preparation, filling every fluid system with the correct oils and greases, the scheduled 50/100/300-flying-hour inspection procedures, winter and summer operating preparation, adjustment of all flight controls, unit-level maintenance of the GTD-350 engines, main transmission, rotor hub, tail rotor and rotor blades, and the specific equipment fit-outs for ambulance, cargo, passenger, and dual-control training versions of the Mi-2.

Oils, Greases and Fluid Standards

The manual includes a dedicated list of oils and greases with their governing standard numbers, covering hypoid oil to GOST 4003-53, TS-gip, AMG-10 to GOST 6794-53/6794-75, Hipol 10F, Shell Aviation Oil S8350, AeroShell Fluid 4 and Fluid 41, MS-20, MS-14, WNII NP-25, and the Elf Aviation and AeroShell engine oil ranges (Grade 100, 80, AD100, AD80, W100, W80) with their DTD, MIL-L and DERD cross-references, so the correct servicing fluid can be matched to the aircraft’s climate and season.

What This Mi-2 Maintenance Manual Enables

With this PZL-Swidnik Mi-2 Helicopter Maintenance Manual in hand, you can carry out preliminary and post-flight inspections, fill and drain the fuel, engine oil, main gearbox, tail rotor gearbox, hydraulic, air, damper and landing-gear shock-absorber systems with the specified fluids and standards, follow the 50/100/300-flying-hour standard procedures, adjust collective, longitudinal, lateral, trim, rotor brake, stabilizer, foot-operated and engine controls, replace the GTD-350 engine, service the main transmission, rotor hub, tail rotor and rotor blades, and maintain ambulance, cargo, passenger, or training-version equipment fits. Working from the manufacturer’s own procedures rather than guesswork keeps torque values, clearances, and fluid specifications correct for the airframe. This Mi-2 Helicopter Maintenance Manual is delivered as an instant PDF download – no shipping, no waiting – so it can be opened immediately on a laptop, tablet, or phone in the hangar, and it can be printed for bench use whenever a paper copy is more convenient.
