Schedule 6 relates to Part 4A of Civil Aviation Regulations (CAR). This schedule sets out the requirements for the certification of completion of maintenance in the CASA system. This applies if you have elected to use that system.
Who it affects
Schedule 6 of CAR affects:
- maintenance personnel
- maintenance organisations.
Understanding the requirements of Schedule 6
We designed Schedule 6 to cater for certification of maintenance of aircraft ranging from a single seat homebuilt aircraft to a Boeing 747. They may engage in private, aerial work and air transport (previously known as charter and regular public transport.
We can summarise the schedule in 2 parts:
- certifications you must make in an aircraft logbook
- certifications you must make in either an aircraft logbook or a maintenance organisation’s work records.
Required entries for a logbook or maintenance organisation records
The following entries you must make into a logbook:
- Certifications for completion of any CAR 42G inspections.
- Final certification.
The following entries you must make into either a logbook or the maintenance organisation’s records:
- Certification for completion of a stage of maintenance if applicable.
- Certification for coordination of maintenance if applicable.
Requirements for approved maintenance data used to carry out the maintenance
Paragraph 4.4(f) of Schedule 6 requires the person making the certification to set out details of the approved maintenance data used to carry out the maintenance.
The record must provide the reader with enough information to identify the source of the data. For example:
- maintenance manual title and version or date of publication
- AD title, if applicable
- service bulletin identity, if applicable.
There is no legislative requirement for a person to detail the data item related to each specific action carried out while completing the maintenance tasks for which the final certification is being made.
Stages of maintenance
Schedule 6 uses the term ‘stages of maintenance’ to describe the point or points when you should certify maintenance.
This is not a prescriptive definition. This is because the appropriate points will vary according to many factors. These may include, but not limited, to the:
- scope of the maintenance
- complexity of the maintenance
- amount of time the maintenance will take or has taken
- licence categories necessary to certify the maintenance
- instructions for continuing airworthiness for the maintenance and
- person or persons responsible for the maintenance.
These factors could also vary if the same maintenance is carried out by different people or in different locations.
The person certifying for the maintenance undertaken must:
- establish stages of maintenance
- consider all the relevant factors
- certify at appropriate stages.
This provides assurance the maintenance was carried out properly and the aircraft remains in a condition safe for flight.
The person certifying the maintenance must be able to explain how the stages of maintenance established were appropriate to ensure that the maintenance was carried out properly and the aircraft is safe for flight.
A stage of maintenance would occur any time a Licensed Aircraft Maintenance Engineer (LAME) either:
- completes part of a maintenance task
- gives a partially completed maintenance task to another LAME.
