In the 1991 Ultra-light Aeroplane Policy, Transport Canada created a sub-category of Ultra-light Aeroplane called Advanced Ultra-light Aeroplanes (AULAs). Transport allowed AULAs that exceeded the normal weight of ultralights at that time if they met certain design standards.

The Light Aircraft Manufacturers of Canada (LAMAC) is the organization that developed the original Design Standards for Advanced Ultra-light Aeroplanes in 1991. These were published by Transport Canada as TP10141.

The Design Standards for Advanced Ultra-light Aeroplanes are referenced in the Canadian Aviation Regulations (CARs) and are now circulated as DS10141 by LAMAC. The current edition includes LAMAC Amendment 003 and is dated November 8, 2004.

The manufacturer of an aeroplane that potentially meets the Design Standards must have it accepted by Transport Canada as an Advanced Ultra-light Aeroplane (AULA) in Canada. LAMAC has no involvement with this acceptance process and provides the following outline information only.

Before a manufacturer’s make and model can be added to the Listing of Models Eligible to be Registered as an Advanced Ultra-light Aeroplane, he must provide Transport Canada with the following documentation:

• maximum empty weight, maximum take-off weight, maximum stalling speed in the landing configuration and the minimum useful load for each approved engine and type of undercarriage;
• a Declaration of Compliance, which is a written declaration that
  • the type definition for your model of advanced ultra-light aeroplane complies with the standards specified in the most current version of the manual entitled the Design Standards for Advanced Ultra-light Aeroplanes;
  • the type definition for that model of advanced ultra-light aeroplane will continue to comply with the standards specified in the manual entitled Design Standards for Advanced Ultra-light Aeroplanes, as long as you continue to manufacture that model of aeroplane as an advanced ultra-light aeroplane;
• a copy of your Specified Maintenance Program, including the inspection schedule and the maintenance procedures to maintain the aeroplane in a “fit for flight” condition;
• a copy of the procedures that you have established for:
  • confirming that each assembled aeroplane conforms with your type definition for that particular model of advanced ultra-light aeroplane,
  • confirming that the assembled aeroplane complies with the standards specified in the Design Standards for Advanced Ultra-light Aeroplanes, and
  • confirming that the assembled aeroplane is fit for flight,
• any other documents or information pertinent to establishing the aeroplane as an advanced ultra-light aeroplane as requested by Transport Canada.

Include any checklists that have been developed to validate that the design meets the requirements.

Once a model has been added to the “Eligible List,” the manufacturer will have to sign a Statement of Conformity for each aeroplane as identified by its serial number. The owner must include this Statement with the registration application and other required documentation in the package he sends to Transport Canada for the initial registration of that particular aeroplane.
