  • (24)

    inspection and continuity checking of self-sealing chip detectors;

  • (25)

    removal and replacement of induction system anti-icing baffles, scoops and

    deactivating or securing inoperative systems in accordance with sections 605.09 or

    • 605.10

      of the CARs, including the installation of devices specifically intended for system

deactivation, where the work does not involve disassembly, the installation of parts, or testing other than operational checks;

(28) checking and adjusting air pressure in helicopter floats, and aircraft tires having an operating pressure below 100 psi, except on aircraft operated under CAR 704 and CAR 705.

(29) repetitive visual inspections or operational checks (including inspections and tests required by airworthiness directives) not involving disassembly or the use of visual aids, performed out of phase with the aircraft’s scheduled check cycle at intervals of less than 100 hours air time, provided the tasks are also included in the most frequent scheduled maintenance check.

Information Notes:

(i) An operational check referred to in (27) above constitutes a check to determine if the unit is working. Operational checks do not involve measuring the unit’s performance against a predetermined standard. Where the testing procedures require such measurement, replacement of the unit shall not constitute Elementary Work. (amended 2004/03/01; previous version)

(ii) Tasks referred to in (29) above are elementary work when performed out of phase, but require a maintenance release when done as part of a scheduled maintenance check.

Elementary work still has to be recorded, as the CAR notes, “The performance of all tasks designated as elementary work shall be entered in the technical record for the aeronautical product, as required by section 571.03 of the CARs and in accordance with Subpart 605, Division IV – Technical Records.”

Maintenance Schedules

A maintenance schedule is the way you keep track of the work that needs to be done next on your aircraft. In fact, unless you own a basic ultralight, advanced ultralight, paraglider or a hang glider then the law requires you to have a maintenance schedule. Most ultralight and hang glider owners have maintenance schedules, too, because it makes sense to take good care of your aircraft, no matter what type it is.
