Air Law and the Regulatory Framework: Documents, Records and Responsibilities
The legal basis of maintenance
Candidates must know the roles of the Chicago Convention, the bilateral airworthiness agreements, and the national regulations that implement them. In the UAE, the GCAA CARs set out airworthiness, maintenance and personnel requirements. Understand the difference between the State of Registry, State of Design and State of Manufacture, and which state is responsible for continuing airworthiness.
Documents and records
Know the purpose and content of the Certificate of Airworthiness, the Certificate of Registration, the maintenance programme, the technical log, and the aircraft maintenance records. Understand retention periods and who is responsible for keeping them. Know what a maintenance release and a CRS mean, and when a flight may be dispatched with a deferred defect under an approved minimum equipment list.
Responsibilities
Understand the operator's continuing airworthiness management responsibilities, the maintenance organisation's approval, and the certifying staff's personal accountability. Know the reporting obligations for occurrences, including mandatory occurrence reporting, and the difference between an occurrence report and a maintenance error report.
Traps
- Confusing the State of Registry with the State of Design when identifying who certifies airworthiness.
- Assuming a deferred defect is an unrecorded defect; it must be recorded and controlled.
- Mixing up the retention periods for different record types.
Rule of thumb
When a question asks "who is responsible?", separate the three layers: the state (regulates), the operator (manages continuing airworthiness), and the certifying staff (certifies the specific task).
