Study Notes
Maintenance Records
- Copies of each ARC issued, recommended, or extended, along with supporting documents, must be retained for up to 24 months after the aircraft is permanently withdrawn from service.
- Records must be protected from damage, theft, and alteration, with computer back-ups stored in a different location.
Line and Base Maintenance
- Line maintenance: routine and preventive maintenance performed on an aircraft before, between, or after flights, including tasks such as checking oil levels, tire pressures, and fuel quantity.
- Base maintenance: periodic and corrective maintenance performed on an aircraft at longer intervals, including tasks such as inspecting structural integrity, testing systems, and overhauling engines.
Troubleshooting
- Troubleshooting: the process of identifying the cause of a malfunction, determining its severity, eliminating the cause, and replacing or repairing discrepant components, systems, or structures.
EASA Part 66 and 145
- EASA Part 66: maintenance certifying staff
- EASA Part 145: maintenance organization approval, including a class and rating system for maintenance categories
Class and Rating System
- Category A: maintenance on aircraft and components when fitted to the aircraft, including "line" maintenance before flight to ensure aircraft fitness.
- Category B: "off-wing" or uninstalled engine and APU maintenance and overhaul.
Airworthiness Review
- The physical survey of the aircraft ensures:
- All required markings and placards are properly installed
- The aircraft complies with its approved flight manual
- The aircraft configuration complies with approved documentation
- No evident defects are found that have not been appropriately addressed
- The airworthiness review can be anticipated by a maximum of 90 days without loss of continuity.
- An Airworthiness Review Certificate can be issued when the airworthiness review is properly carried out and the aircraft is airworthy.
