Owner-maintenance category is open to a list of unsupported, small aircraft. Pilot/owners of aircraft switched into this category are eligible to perform the maintenance on their aircraft; effect modifications and repairs without Transport Canada approval; install uncertified parts; and sign the maintenance release for all maintenance performed.
The Owner-Maintenance Category was developed to allow certain certified fixed-wing aircraft to be maintained, modified and upgraded under similar regulations as amateur built aircraft.
Owner-Maintenance Category became part of Transport Canada’s Recreational Aviation Policy in June 1996. That policy was accepted and approved by the Minister of Transport.
Under the O-M Category, Aircraft Pilot/Owners are Eligible To:
maintain an airplane
refurbish all or part of an airplane
overhaul all or part of an airplane
install certified and uncertified parts
install or replace any instruments or avionics
modify an airplane
rebuild an airplane that is out of service
sign the maintenance release.
