Airworthiness Manual Advisory (AMA)

Appendix A

Information Note:

The purpose of the Checklist is to record the amount of fabrication and assembly accomplished by the kit manufacturer, and the fabrication and assembly necessary for the builder to complete the aircraft.

The numbers derived from the "manufacturer" and "builder" columns on the checklist indicate the percentage of the aircraft fabricated and assembled by the manufacturer and the builder.  To meet the requirements of Chapter 549 the sum total in the builder's column must be greater than in the manufacturer's.

It is not necessary that a major portion of the individual parts be fabricated by the builder.  If there is some work; i.e., trimming, measuring, cutting, drilling, gluing, layup, etc., required to prepare the individual part for installation/assembly into the aircraft, and if this work is performed on a representative number of parts listed under each applicable section of the aircraft, the kit would be considered eligible, as long as fabrication and assembly make up the "major portion".

As used in this AMA: 

"fabricate" means to make or construct parts or assemblies from raw materials or other parts.  This involves operations such as measuring, cutting, drilling, bending, welding, riveting, gluing, bonding, etc.  It also involves operations such as soldering, crimping, swaging, "covering" and painting.

"assemble" means to fasten parts or assemblies together, using screws, bolts, nuts, or other mechanical fasteners.

Instruction for Completing Checklist

  1. Enter the kit manufacturer's company name and address.

  2. Enter model of kit by name and/or number.

  3. List the latest date or revision date of kit parts list.

  4. Enter type of aircraft (land, sea, fixed-wing, rotorcraft    etc.).

  5. Enter the date of the evaluation.

  6. Review each operation for its applicability to the kit under  evaluation.

  7. Check the respective block under "accomplished by" (manufacturer, or builder).

  8. Enter any operations not on list in blank spaces.

  9. If the operation is not applicable to the kit construction enter "N/A" in the respective blocks.

  10. Operations that are accomplished by other manufacturers or suppliers are to be checked in the kit manufacturer block.

  11. Only special tools and fixtures, (i.e., jigs, templates, etc.) fabricated by the builder will be give credit.  (No credit for hand tools).

  12. When the evaluation is complete the total check marks are to be entered in the respective blocks on page 3 of the checklist.

  13. Sign and date the checklist.

Instructions For Determining Totals To Complete An Amateur-Built Aircraft Kit, using the Checklist at Annex A.

  1. For each item on the checklist (Annex A) that is accomplished by the manufacturer, a checkmark is entered under the "KIT MANUFACTURED" column.  This should not include jigs, special fixtures, etc.

  2. For each item that is fabricated or installed by the amateur-builder, a checkmark is entered under the "AMATEUR BUILDER" column.  This can include jigs and fixtures that would be necessary for the amateur-builder to make in the fabrication of the aircraft or components thereof.

  3. When this is completed for the aircraft the two columns are totalled and the percentage of checkmarks in the "AMATEUR BUILDER" column determined.

TOTALS

Sample Letter To Applicantwhen Kit Is Determined To Be Eligible

Applicant's Name

Dear Sir:
Transport Canada Aviation has completed evaluation of the (Aircraft Model) kit.  We have determined that the kit, as evaluated at your facility on (date), and defined by parts list (date/revision) meets the intent of Chapter 549 (Section 549.5) of the Airworthiness Manual.  "The major portion of the aircraft (more than 50%) is fabricated from raw material and assembled by an individual or a group of individuals on a non-commercial, non-production basis for educational or recreational purposes".
This evaluation should not be construed to mean that the kit is "certified," "certificated", or "approved" and it is not appropriate to represent it as such.  It may be represented as eligible for construction as an amateur-built aircraft under the provisions of Chapter 549 of the Airworthiness Manual.
Copies of the kit parts list, identified by date and/or revision, shall be provided with kits supplied to customers.  This will assist the builders in identifying the configuration of the kits for the final approval of the completed aircraft.  Any changes to the configuration or contents of the kits and parts lists may affect the eligibility of the kits.
