Definition:
Approved maintenance program is the main reference for maintenance scheduling, planning and all maintenance tasks required to put the aircraft in airworthy condition, it contain all preventive maintenance activity required by local authority, type certificate authority and operator requirements.
What are expected to be inside the approved maintenance program?
As the maintenance program is the main reference for maintenance scheduling, planning and all maintenance tasks required to put the aircraft in airworthy condition, so AMO expected to include:
- Maintenance Program Approval letter (from local authority).
- Distribution list (to all concerned person).
- Summary of changes.
- Abbreviations.
- Airworthiness limitation.
- Aircraft and APU utilization ratio - flight hour to flight cycle ratio and flight hour per year -which the AMP developed depending on it ().
- All applicable modifications.
- A list (in the form of a long table) of all maintenance tasks which need to be performed on an aircraft from time to time. And repairs need periodic inspection .In other words, based on the AMP an airworthiness engineer knows exactly what tasks need to be performed after an aircraft reaches a certain point in life, be it calculated based on calendar age, flight hours of flight cycles.
- Airworthiness Directives ADs status.
- Service Bulletin SBs status.
- Reliability Control Board RCB recommendations.
- Certification Maintenance Requirements (CMR).
- System Equipment Maintenance Requirements (SEMR).
- ETOPS Configuration, Maintenance and Procedures (CMP).
- Fuel Airworthiness Limitations.
- Maintenance escalations rules.
- Life Limited Parts /Time Change Items.
- Local authority maintenance requirements for airworthiness.
- Structure program.
- Corrosion Prevention program.
- Engine Monitoring program.
- Aircraft Utilization Limitation / Limit Of Validity (LOV)
- Cat II/Cat III landing capabilities, Reduced Vertical Separation Minima (RVSM) capabilities and Extended Twin Engine Operations (ETOPS) are inherent functions of the basic design standard of the aircraft. Scheduled tasks necessary for these operations have been considered in the development of the AMP. Operators should comply with National Requirements as applicable.
