Chad Gustafson

Chad for web

Chad is a Certified Flight Instructor from the Pacific Northwest. He flew general and corporate aircraft out of Port Angeles, WA. Which included- Aeronca Champ on floats, Aeronca Sedan, Avid Flyer on floats, Vans RV7, RV6, Christen Eagle II, Cessna 150, 172, 182, 206T, 310, Citabria Decathalon, Beachcraft V tail, Baron 55, King Air C90, Diamond Twin Star DA42, Embraer Brasilia EMB-120. Avionics- Garmin 400 series, Garmin touch screen series 650-750, G1000, Apollo GNS480, MX20

Chad started flying as a convenient way to travel to water ski tournaments in the Pacific Northwest. The next step was a 1955 Champ on straight floats. An IFR rating and a Baron 55 for the overcast days led to a King Air C90 for work. Naturally when the fuel bill arrived, a Vans RV7 soon followed, which led to a Christen Eagle II. His next plan was to teach his two teenage daughters to fly, so the CFI check ride was checked off. Two unforeseen challenges lay ahead. First, his oldest daughter informed him that she and her sister were not going to learn to be pilots. As she put it, “Dad, you can just fly us wherever we want to go, way easier, ok?” (apparently Dads can’t see the forest for the trees on occasion). Secondly, Chad way underestimated the teaching of said daughters to drive a car! Yes, they are all still friends, however, Chad learned that flight lessons are best left to people that want to learn to be pilots, so if your interested in going for your first flight, a flight review or transitioning to tailwheel, Chad is likely to be hanging out at Santa Paula airport.
