Guide to maintenance schedule

The builder / owner of a Canadian-registered amateur-built aircraft is responsible to prepare and follow a maintenance schedule in respect of his/her aircraft.

What is a maintenance schedule?

The maintenance schedule includes (1) a checklist of the scheduled inspection requirements for the airframe, engine(s), propeller(s), appliances, survival equipment, emergency equipment and other equipment installed on the aircraft — what to inspect, when to inspect, what to look for — and (2) the applicable requirements for out-of-phase and equipment maintenance requirements of APPENDIX C, STANDARD 625.

Where can I find information on the contents and format?

PART I OR PART II OF APPENDIX B, STANDARD 625.

Where do I find a checklist?

The builder / owner must develop his/her own checklist, tailored to his/her aircraft, which must include, at the very minimum, all the items listed in PART I OR PART II OF APPENDIX B, STANDARD 625, as applicable.

Many aircraft manufacturers produce detailed inspection checklists. In many cases, the location of system components is clearly identified on those documents. In the interest of efficiency, an owner may wish to use a manufacturer’s checklist. Where an owner has chosen to use a manufacturer's checklist, it should be clearly marked to indicate that the check is following the requirements of PART I OR PART II OF APPENDIX B, STANDARD 625.

What information has to be recorded?

All items inspected, as per the checklist that is part of the maintenance schedule.

What about out-of-phase items?

An inspection checklist should provide space for recording other maintenance activities, such as defects found and rectified during the scheduled inspection and the completion of tasks with respect to out-of-phase items and equipment maintenance requirements of APPENDIX C, STANDARD 625.

Do airworthiness directives (ADs) apply to amateur-built aircraft?

ADs do not apply to amateur-built aircraft (see CAR 605.84(1).

What do I do if my aircraft is damaged?

You can find information in APPENDIX G - INSPECTION AFTER ABNORMAL OCCURRENCES, STANDARD 625.
