摘要
LCA Engine is mounted on aircraft using three mounting points such as Engine mount stbd, Mount bracket with swing grip and link assembly. Expandable pin will be used to mount the engine with link assembly. It is possible to carry out the inspection of proper mounting of the expandable pin between the engine mount and the link assembly only after installation engine on the aircraft. The link assembly has to be finalized in the detail stage as there would not be any accessibility after engine installation. In case of not matching, the entire assembly has to be rejected and to be initiated new manufacturing. It would not be affordable at that stage as it would hold up the assembly in jig till the new one is fabricated. Also, there is no guarantee that the newly manufactured assembly also would meet the requirement. Hence, there is a need for an alignment checking fixture to inspect the expandable pin without depending upon the installation of engine on the aircraft at final stage.
