Transport Canada regulations allow owners of
private certified aircraft to perform many technical services in the course of
maintaining an airworthy aircraft condition.
Appendix “A” of Chapter #575 of TC’s Airworthiness Manual spells out the
functions that are allowed to be performed by the owner of a private aircraft.
These are listed as follows:
Elementary maintenance on small private airplanes and balloons
In accordance with 575.109(a)(1), no maintenance release is required in respect
of the following tasks when performed on a glider, a balloon or a piston engine
powered unpressurized airplane of 5,700 kg (12,566 pounds) or less maximum
allowable takeoff weight, not engaged in commercial operation by the pilot of
the aircraft.
(1) Fabric patches measuring not more than 15 cm (6 inches) in any direction and
not requiring rib stitching or the removal of control surfaces or structural
parts;
(2) Replacement of tires, wheels, landing skids or skid shoes, not requiring
separation of any hydraulic lines;
(3) Seasonal re-installation of skis on fixed landing gear, not requiring
separation of any hydraulic lines;
(4) Replacement of seats, safety belts and harnesses;
(5) Repair of fairings, nonstructural cover plates and cowlings;
(6) Repair of upholstery and cabin trim;
(7) Re-installation of glider wings and tail surfaces which are designed for
quick assembly;
(8) Cleaning and installation of spark plugs;

document, as being within the privileges of a pilot.
Private aircraft owners who want to learn more about maintaining their own
aircraft are encouraged to join EAA or RAAC Chapters in their respective areas.
The exchange of technical information among members of these organizations is a
great learning experience.
