Division III — Aircraft Maintenance Requirements

Aircraft Maintenance — General

• 605.84 (1) Subject to subsections (3) and (4), no person shall conduct a take-off or permit a take-off to be conducted in an aircraft that is in the legal custody and control of the person, other than an aircraft operated under a special certificate of airworthiness in the owner-maintenance or amateur-built classification, unless the aircraft

  • (a) is maintained in accordance with any airworthiness limitations applicable to the aircraft type design;

  • (b) meets the requirements of any airworthiness directive issued under section 521.427; and

  • (c) except as provided in subsection (2), meets the requirements of any notices that are equivalent to airworthiness directives and that are issued by

    • (i) the competent authority of the foreign state that, at the time the notice was issued, is responsible for the type certification of the aircraft, engine, propeller or appliance, or

    • (ii) for an aeronautical product in respect of which no type certificate has been issued, the competent authority of the foreign state that manufactured the aeronautical product.

• (2) In the case of a conflict between an airworthiness directive issued by the Minister under section 521.427 and a foreign notice, the airworthiness directive prevails.

• (3) The Minister shall exempt the owner of a Canadian aircraft from the requirement to comply with all or part of an airworthiness directive, subject to appropriate conditions relating to aviation safety, as specified in Appendix H of the Aircraft Equipment and Maintenance Standards, where the owner demonstrates to the Minister that

  • (a) under circumstances specified in the exemption request, compliance is impractical or unnecessary; and

  • (b) the exemption will provide a level of safety that is equivalent to that required by the airworthiness directive.

• (4) The Minister shall approve an alternative means of compliance with an airworthiness directive, for reasons set out in the approval, where the Minister is satisfied that the proposed alternative will maintain the level of safety that is provided for by the compliance time, the modification, the restriction, the replacement, the special inspection or the procedure set out in the airworthiness directive.

Maintenance Release and Elementary Work

• 605.85 (1) Subject to subsections (2) and (3), no person shall conduct a take-off in an aircraft, or permit a take-off to be conducted in an aircraft that is in the legal custody and control of the person, where that aircraft has undergone maintenance, unless the maintenance has been certified by the signing of a maintenance release pursuant to section 571.10.

• (2) Where a maintenance release is conditional on the satisfactory completion of a test flight pursuant to subsection 571.10(4), the aircraft may be operated for the purpose of the test flight if no person is carried on board other than flight crew members and persons necessary for the purpose of making observations that are essential to the test flight.

• (3) Following a test flight conducted pursuant to subsection (2), the pilot-in-command shall enter the results of the test flight in the journey log and, where the entry indicates that the results of the test flight are satisfactory, that entry completes the maintenance release required by subsection (1).

• (4) No maintenance release is required in respect of tasks identified as elementary work in the Aircraft Equipment and Maintenance Standards.

Maintenance Schedule

• 605.86 (1) Subject to subsection (3), no person shall conduct a take-off in an aircraft, or permit a take-off to be conducted in an aircraft that is in the person’s legal custody and control, unless the aircraft is maintained in accordance with

  • (a) a maintenance schedule that conforms to the Aircraft Equipment and Maintenance Standards; and

  • (b) where the aircraft is operated under Subpart 6 of Part IV or under Part VII, or is a large aircraft, a turbine-powered pressurized aircraft or an airship, a maintenance schedule approved by the Minister in respect of the aircraft operator pursuant to subsection (2).

• (2) The Minister shall approve a maintenance schedule in respect of an aircraft if the schedule conforms to the Aircraft Equipment and Maintenance Standards.

• (3) The Minister shall authorize an operator to deviate from the requirements of the applicable maintenance schedule where the operator

  • (a) submits a request in writing to the Minister in accordance with the Aircraft Equipment and Maintenance Standards; and

  • (b) demonstrates that the deviation will not affect aviation safety.

Transfer of Aeronautical Products between Maintenance Schedules

605.87 No aeronautical product shall be maintained in accordance with a maintenance schedule that is different from the one under which it was previously maintained unless

• (a) the aeronautical product has been subjected to an inspection that establishes it on the new maintenance schedule; and

• (b) the times remaining until each action on the new maintenance schedule is to be taken have been established in accordance with the Aircraft Equipment and Maintenance Standards.

Inspection after Abnormal Occurrences

• 605.88 (1) No person shall conduct a take-off in an aircraft that has been subjected to any abnormal occurrence unless the aircraft has been inspected for damage in accordance with Appendix G of the Aircraft Equipment and Maintenance Standards.

• (2) Where the inspection referred to in subsection (1) does not involve disassembly, it may be performed by the pilot-in-command.

• 605.92 (1) Every owner of an aircraft shall keep the following technical records in respect of the aircraft:

  • (a) a journey log;

  • (b) subject to subsections (2) and (3), a separate technical record for the airframe, each installed engine and each variable-pitch propeller; and

  • (c) except where otherwise provided under the terms of a fleet empty weight and balance program referred to in subsection 706.06(3), an empty weight and balance report that meets the applicable standards set out in Standard 571 — Maintenance.

  • (c) date the entry.

• (4) Every person who brings into use a new volume of an existing technical record shall make the entries relating to the preceding volume that are necessary to ensure that an unbroken chronological record is maintained.

• (5) Subject to subsection (6), where a person alters an entry on a technical record for the purpose of correcting the entry, the person shall do so by striking out the incorrect entry in such a manner that the underlying information remains legible, and inserting the correct entry together with
