EAA SportAir Workshops in Canada!
Three EAA SportAir Workshops are tentatively planned in two central Canada locations this fall. All three will be held on Saturday and Sunday, October 18-19, and include:
- Toronto: Sheet Metal Basics, at Kitplane Builders, #5 Meyerside Drive, Mississauga, ON, and:
- Ottawa: Electronics/avionics, and Amateur-Built Aircraft Inspections, at the EAA Chapter 245 Hangar - Carp Airport, Carp, ON
These two-day structured workshops are designed to help you build and maintain your amateur-built aircraft. They are comprehensive courses which provide students with an incredible amount of knowledge and confidence. Course sizes are limited so that students can receive individual instruction and help. The fee for each course is $300 Can. and includes materials, tools and workbook. Students will receive an EAA SportAir Certificate upon course completion.

Sheet Metal Basics
Day one starts with a discussion of the basics of sheet metal construction. We cover the different aluminum alloy designations and their applications. We identify the various rivet types and discuss in-depth their uses and applications.
We then move on to the hands-on workshop where students put their new-found theory to practical use by constructing a 'practice-project' designed to illustrate sheet metal construction. Students lay-out rivet lines, drill, de-burr, dimple, countersink and drive the various rivets. Tools are discussed and demonstrated. Students are given the opportunity to identify, drill out, and replace defective rivets.
In the afternoon of day one, students team up in twos to construct an airfoil kit. This kit is a small example of a wing or control surface and is designed to introduce the student to virtually all aspects of sheet metal construction encountered in building a sheet metal aircraft.
The second day starts with a further discussion of aircraft construction methods and Canadian Rules and Regulations for amateur-built aircraft. Returning to the workshop, students complete their wing kit. When completed, each project is reviewed individually with the instructor.
This course is designed to help the builder handle the electrical and electronic building concepts. It starts with the very basic assumptions necessary for a clean, clear electrical design. Fundamentals of electric circuits, starting with the simplest basic circuit, slowly evolve to more complex series and parallel circuits, to circuit protection, switch poles and throws, distributing buss concepts, load ratings, until all basic applications and components are fully explained.
By mid-morning, electrical system loads, battery and alternator capacity, real-world battery performance and capacity, electro-magnetic, alternator regulation, and magneto-based ignition systems are discussed.
Students are introduced to soldering, wire stripping, wire tinning, splicing wires, and heat shrink concepts. They are also introduced to avionic applications; open barrel pin and socket, AMP PIDG terminals D-sub Connectors. Day one is completed with the students wiring an Intercom Harness.
Day two begins with a re-cap of the theory and completion of the intercom wiring exercise.
Students move on to Antennas and RF Energy discussions including electromagnetic waves associated with antennas and accessories, ground plane theory, bonding, and shielding of RF noise.
Having mastered electrical and electron theory, students will discuss real world examples, vendor catalogs, and the dissection of an avionics installation manual. Finally, each student will have an individual craftsmanship critique by the instructor.
Amateur-Built Aircraft Inspections
This interactive course of studies is based on the requirements of the amateur-built aircraft owner to comply with the maintenance requirements of CAR 625 B & C. It is broadly based on the FAA credited course for the Repairman's Certificate for the ELSA aircraft category.
The course objective is to provide the Canadian aircraft owner of an amateur-built aircraft enough training so that he or she can confidently carry out the annual inspection and determine that the aircraft is in a condition for safe operation, and then sign out the required logbook entry.
The course starts with a review of the Rules and Regulations relating to the Canadian amateur-built aeroplane. It covers maintenance issues and time schedules, required documents and documentation, weight and balance issues, and operating limitations. It covers placards, and defines 'minor' and 'major' changes and subsequent requirements. It also discusses 'airworthiness directives' (ADs) and service letters, and their effects and compliance requirements for amateur-built aircraft.
A "safety" section includes human factors, "Pre-task" and "Post-task" personal checklists.
Clarity and non-ambiguous definitions of the "purpose of inspections" help the student understand his or her role in the maintenance of the amateur-built aeroplane. A structured 'inspection procedure' is presented. Theory of flight and the evaluation of primary flight controls, secondary flight controls, and auxiliary flight controls are discussed.
Critical areas and rigging requirements for stable flight are covered. Procedures for rigging requirements and tools are discussed. The object is to get the aircraft to fly "hands-off."

Typical Comments and Evaluations From Students
"I had started my empennage prior to this workshop and it has given me the confidence to continue and to know what to expect. Thank you very much!" - Luc B., Quebec
"Excellent instruction; depth of knowledge, teaching ability, great pace, entertaining! Workshop gave confidence to order and build project!" - Dave M., Alberta
"I will attend any SportAir Workshop in my area. There is so much to learn. Excellent! Well done!" - J. Russel K., Alberta
"Excellent overall experience. This has given me basic information and confidence to begin my project. Thanks for coming to Ontario." - David H., Ontario
"Superb class! Excellent, knowledgeable instructor and FUN FUN class. - Bruce T., Washington
"Excellent Workshop! Found out I enjoy the metal process more than I expected. The next step is more and more fun. What I thought were big steps and time consuming-proved otherwise!" - Jeff K., Saskatchewan
