AMP Update Procedure
Overview
The Aircraft Maintenance Program (AMP) defines the required tasks and intervals to ensure continued airworthiness. Updating the AMP is a critical CAMO responsibility, driven by manufacturer revisions, operational experience, or regulatory changes.
When to Update AMP
- New revision from aircraft/engine/APU manufacturer
- Changes in EASA regulations or airworthiness directives
- Escalation based on in-service reliability
- Introduction of new equipment or configurations
AMP Revision Workflow
1. Source the New Requirements
- Review latest MRBR, MPD, or ALS from OEM
- Compare against current AMP version
2. Draft the AMP Update
- Update task list, intervals, and thresholds
- Classify tasks: zonal, systems, structural, LLP, etc.
- Format into approved AMP structure (Excel, XML, CMS)
3. Internal Review
- Cross-check impact on aircraft availability
- Review with Engineering and Planning teams
4. Submit for Approval
- Send draft AMP to NAA (or contracted Part-21 organization)
- Address feedback and resubmit if required
5. Publish and Implement
- Load AMP into Maintenance System
- Notify all stakeholders (maintenance, QA, CAMO)
- Archive previous revision with approval references
