A process for utilizing Aerospace Propulsion Health Management Systems for Maintenance Credit
The process detailed within this document is generic and can be applied to commercial and military applications. It applies to the entire end-to-end EHM system throughout its lifecycle, covering on-board and on-ground elements.
This document does not prescribe hardware or software assurance levels, nor does it answer the question “how much mitigation and evidence is enough”. The criticality level and mitigation method will be determined between the ‘Applicant’ and the regulator.
In order to provide some detailed guidance utilising the process and checklist, some high level examples of previous successful cases of Maintenance Credit applications are included.
Rationale: The purpose of this document is to provide a process to achieve Maintenance Credits in a consistent way. The practical application of this standardised process is detailed in the form of a checklist. This will help Regulators carry out assessments of the merits of a Maintenance Credit application with a view to provide approval.
