Use during main rotor adjustment

For use, the tool is placed over the trim tab until it reaches the stop. The technician then applies a smooth force to the handle to bend the tab in the required direction. The manual links this operation to main rotor blade coning adjustment, so the amount and direction of correction must come from the approved rotor tracking procedure rather than from the tool itself.

The tool does not measure blade track and does not establish the required correction. It provides controlled mechanical leverage after the maintenance result has been evaluated with the appropriate tracking equipment. Excessive or abrupt loading can damage the trim tab or blade structure, which is why the procedure specifically calls for smooth force.

Confirmed construction and mass

The primary manual gives a mass of 0.7 kg. This corrects the earlier generalized value of 0.8 kg on the product page. Search forms 56.9918.00 and 56 9918 00 are included as alternative punctuation, while NVKV.303674.001 is recorded as a documented newer designation. None of these forms should be treated as proof of interchangeability without dimensional confirmation.

Before use, inspect the bracket for deformation, cracks and damaged protective lining. Check the handle attachment and ensure the groove is clean so that the trim tab surface is not scored. Because no independently verified product photograph was found, the gallery uses the exact maintenance-manual illustration instead of an invented or visually similar image.

Ordering 56-9918-00

This card retains the existing price and Pre-Order status. Condition is recorded as New, Warranty as 6 Months and YOM as 2026. The estimated lead time remains 90–120 days subject to confirmation. The supplied tool should be checked against the drawing, dimensional requirements and any passport or inspection record included with the delivery.

An inquiry should identify the helicopter modification, quantity and required documentation. Other Mi-8 / Mi-17 ground tools linked from this page are related only through the maintenance category. They are not substitutes for the 56-9918-00 fixture and must not be used to bend rotor-blade trim tabs unless their approved documentation explicitly permits it.
