Acceptance of Aeronautical Products
- AMOs must classify and segregate aeronautical products intended for use in aircraft maintenance.
- AMOs must keep copies of documents confirming conformity and traceability for two years after use or fitment.
Fabrication in the Course of Maintenance (FITCOM)
- AMOs can fabricate aeronautical products if for maintenance, but must comply with design data.
- This includes dimensions, materials & fabrication processes, assembly, inspections, and test procedures.
- The products must have proper marking details as described in design data and relevant markers to identify the AMO.
- AMO must keep records for two years after the product is removed from service.
- Products must be fabricated according to the AMO's Exposition.
- The AMO must certify product compliance with each applicable process (assembly, inspection, testing, marking).
Instructions for Continuing Airworthiness (ICA)
- AMOs are expected to have maintenance data for specific aircraft/aeronautical products, listed on the Approval Certificate or in the Capability Statement.
- If locations are listed, data is expected to be stored there.
- AMOs can subscribe to online providers if data source and access methods are outlined in the Exposition.
- AMOs must use the data and maintain copies of all maintenance records for the duration of provided services.
- AMOs must ensure ICAs are readily available to personnel for use as required
Maintenance Data
- If specific aircraft/aeronautical products are not explicitly listed on the approval certificate, a compliance method is to present procedures to access relevant maintenance data in the Exposition.
- Sources for this data may include the Registered Operator(RO), vendors, or aircraft owners.
- AMOs may generate their own data if it doesn't involve wear limits and if no existing data covers the particular maintenance.
- Procedures for new data generation and approval are detailed in the Exposition.
- Maintenance data procedures must specify procedures for ensuring data accuracy and avoid ambiguity.
Calibration for Test Equipment (More Detailed)
- Tools and equipment requiring calibration must be either factory recommended, nationally recognised, and/or per procedures outlined in the AMO's Exposition.
Tool Calibration (More Detailed)
- AMOs must maintain records of tool calibrations, including the standard of calibration used.
- Procedures for managing aircraft/aeronautical products following maintenance that used tools outside of specified tolerances are needed.
Certification of Maintenance for Aircraft
- AMOs must issue CRSs for aircraft/aeronautical products where maintenance is carried out.
- AMOs must notify the person for continuing airworthiness of any new defects found during maintenance.
- AMOs must document any maintenance tasks not completed at the time of issue.
Certification of Maintenance for Aeronautical Products
- An AMO must create a CRS for aeronautical products after maintenance.
- CRS forms/procedures are determined by CASA specifications or AMO specifications/Exposition guidelines.
- If the AMO is unable to complete the requested aircraft maintenance, they must issue a CRS only as per guidelines of Subpart 42.
- If there are outstanding defects or tasks that weren't completed, these must be documented.
Fitting Parts With No Authorised Release Certificate
- Fitting parts to an aircraft without the required CRS is allowed under certain conditions.
- The part must be serviceable.
- The supplying organization must be identified and the authority for the document.
- The responsible party for airworthiness must agree to the part fitting.
- Obtaining an authorised CRS for the part must be documented within 36 flight hours.
- The part must be removed if necessary.
Maintenance Records
- AMOs must have adequate maintenance records that document all maintenance processes, certifying employee involvement or maintenance procedures.
- Detailed records for calibrated test equipment are also necessary for traceability.
- Maintenance records must be kept for two years. Electronic records require back-up for two years and in a separate location.
Occurrence and Major Defect Reporting
- AMOs must establish internal systems for reporting, investigating, and managing maintenance and safety issues.
- Reporting procedures must address both individual errors and any wider systemic issues.
- Reporting should follow principles that prevent employee punishment for reporting such issues.
AMO Exposition Requirements (Safety and Quality Policies)
- AMOs must define clear safety policies as the overriding priority for all activities.
- Policies must require reporting of maintenance-related incidents and errors.
- Employees must follow established quality and safety standards/procedures.
- Employees must co-operate with quality audits undertaken by independent parties.
Maintenance Procedures
- AMOs must outline procedures that ensure good maintenance practices, complying with the MOS and regulations.
- Procedures should consider human factors and performance limitations, document release of aircraft/aeronautical products, ensure facility compliance, and have well-defined standards.
- Prevent employees from working if significant impairment is deemed to exist.
- Address any damage beyond acceptable limits and use appropriate design approvals for modifications/repairs.
- Procedures for aircraft maintenance must include capturing maintenance errors effectively, ensure allocation of tasks to avoid duplicate work on the same aircraft/part, and if one person is not available, additional inspection steps must be made post-maintenance.
Quality Management System (QMS)
- An AMO must have a documented QMS that includes independent surveillance and auditing every 12 months to ensure regulatory compliance.
