New versions of parts, components o

New versions of parts, components or software may require an installation on one or several end product, for example to complete the validation of these new configurations or to execute an investigation test.The Limited Fleet Test process (see Figure 7 section 9) provides a controlled authorization, given by a cross functional team, to install this part, component or software on a limited number of products (limited fleet) with the objective to perform a specific test.The LFT process uses the mechanisms of the Change Management Process.The process starts with a Change Request proposing to modify an ETR with a new part. If the LFT is necessary and approved, the temporary configuration is documented in the corresponding ETR and a retrofit order (AVM in ERP and Work Order in Maximo) is issued to authorize the physical implementation on the product. The Change Request is maintained on hold awaiting for test results.The test results are used to determine whether the part, component or software can be deployed on one or several active ETRs or rejected. The Change Request gets then approved or rejected.The Limited Fleet Test process is an enabler of Product Safety as it allows a strong control of any modification made on the product.
