Role of 8AT.7421.210 in maintenance work

The functional role of the item is represented by the supplied product type, Tail Rotor Wiring Harness Mi-8. Work planning should match the designation to the relevant task card, serviced component and aircraft configuration. This page does not imply compatibility with every aircraft or helicopter merely because another tool has a similar appearance. When a drawing or manual reference is not available, an inquiry should include clear photographs of the existing equipment and a description of the intended operation.

Related products in the Ground Support Equipment category may be used during the same maintenance event, but they are not interchangeable. Slings, trolleys, plugs, measuring devices, hydraulic servicing equipment and installation fixtures perform different functions and must be used only within their documented procedures.

Designation and configuration checks before ordering

Before ordering, verify the complete 8AT.7421.210 designation, product name, execution, interfaces, delivery set and required documentation. For lifting and installation equipment, confirm load limits and attachment points. For hydraulic equipment, confirm the working medium, pressure and connections. For measuring tools, confirm the range, accuracy and inspection method. These values must not be copied from a similar product without documentary support.

Incoming inspection should cover the body, welded and threaded joints, fasteners, cables, hoses, locking devices and identification markings, as applicable to the construction. External appearance alone does not establish readiness for service. Actual condition, delivery completeness and suitability for a particular task remain subject to the supplied records and the recipient’s approved inspection procedure.
