56-9907-00 Tail rotor gearbox lifting sling

56-9907-00 is a tail rotor gearbox lifting sling identified through the exact designation and specialist listings. Lifting the Mi-8/Mi-17 tail rotor transmission or tail gearbox during removal and installation. This page describes the specific item and does not copy specifications from equipment that merely looks similar.

Specialist Mi-8/Mi-17 ground-equipment catalogs consistently identify 56-9907-00 as the sling for the tail rotor gearbox. This sling is a separate drawing from 8MT-9925-00, which is also listed for tail gearbox handling in later configurations. This distinction matters in search and procurement: the base number, letter index, suffix and model reference should agree with the applicable documentation or the marking on the available item.

Maintenance role of 56-9907-00

The product is used as ground support equipment. It is not a universal tool simply because another fixture performs a comparable task. Before use, maintenance personnel should confirm the approved task card, serviceability, attachment or connection points, and the permitted aircraft or component configuration.

The required helicopter execution, rated load, attachment arrangement and inspection status must be confirmed from maintenance documents and the sling tag. When a value is absent from the located documentation, it is not replaced with a calculation or a specification from a neighbouring model. This keeps the page technically accurate and allows the customer to request a passport, drawing or test record separately.

Designation and compatibility checks

Before ordering, compare 56-9907-00 with the maintenance manual, ground-equipment catalog or delivery-set list. Also verify interfaces, working medium, load or pressure range, included accessories and periodic inspection requirements whenever those characteristics apply to this type of equipment.

Products linked within the same category may support the same aircraft family, but they are not substitutes. A jack, crane, trolley, valve or servicing control unit performs its own operation and must be used only in the documented configuration.

Confirmed and unconfirmed technical data

Part number and tail gearbox lifting function are confirmed by specialist Mi-8/Mi-17 catalogs; no reliable public load or mass data were found. Unverified dimensions, mass, pressure, rated capacity or applicability are intentionally omitted. Where a reference value is shown, the text identifies its status and requires confirmation against the passport for the supplied unit.

Incoming inspection should check the identification marking, body and joint condition, completeness, fasteners, hoses, cables, locks and working elements as applicable. Operational readiness is established through records and the approved inspection procedure, not appearance alone.

A technical inquiry is more useful when it includes the manual or equipment-list page that names 56-9907-00, together with photographs of the marking and interfaces on the existing sample. This helps separate the base model from a suffix-specific execution and allows the delivery set to be agreed in advance. For lifting, pumping or pressure-control equipment, the request should also state the required current inspection or test documentation.

Before release to service, a new or stored item should pass the recipient’s approved incoming inspection. Mechanical fixtures require checks for deformation, corrosion, thread damage and locking parts. Hydraulic equipment requires confirmation of fluid compatibility, seal condition and leakage control. Valves and servicing panels require clean passages, correct connections and functional control checks. The operator’s documentation determines subsequent inspection intervals.
