What Is the Aircraft Engine Maintenance Fixture?

The 856A4013G02 is identified as a specialized Aircraft Engine Maintenance Fixture under Federal Supply Classification (FSC) 4920, which covers aircraft maintenance and repair shop specialized equipment.

Unlike general-purpose workshop fixtures, an engine maintenance fixture is designed around specific component maintenance requirements. The 856A4013G02 is associated with operations that require engine components to be positioned and supported during resizing and distortion removal.

The fixture is identified by:

Part Number: 856A4013G02

Nomenclature: Fixture, Engine Maintenance, Aircraft

NSN: 4920-01-168-0278

NIIN: 01-168-0278

CAGE Code: 58828

FSC: 4920

Reference: SERD No. 0905

These identification details make the 856A4013G02 suitable for precise tooling identification and procurement within aviation maintenance environments.

Application for CFM56-3 Engine Maintenance

The CFM56-3 is a widely used commercial turbofan engine, and its combustion-section components require dedicated inspection and maintenance procedures throughout their service life.

Available maintenance capability information associates the 856A4013G02 with CFM56-3 maintenance applications involving combustion inner and outer cowl components.

This makes the fixture relevant to MRO facilities working with CFM56-3 combustion-section maintenance and associated component repair procedures.

When specialized tooling is required for engine component restoration, using a fixture identified for the relevant maintenance application can help establish a more controlled and repeatable repair setup.

Combustion Component Resizing and Distortion Removal

One of the key functions associated with the 856A4013G02 is engine component resizing.

Combustion-section components are exposed to significant thermal and mechanical conditions during engine operation. After extended service or maintenance activities, dimensional changes or distortion may need to be addressed as part of the component repair process.

The 856A4013G02 is documented for applications involving components such as:

Combustion liners

Outer liners

Domes

Related combustion-section components

During maintenance, the fixture provides dedicated support and positioning for the component while resizing or distortion-removal operations are performed.

This type of tooling is especially important where component geometry and positioning need to be controlled throughout the maintenance process.
