US Airplane Factory Team
Matt Liknaitzky
CO-CEO
Matt Liknaitzky grew up in South Africa and had a passion for aviation at an early age. He started flying Microlights at age 16 and at 19 went to work for a small aircraft manufacturer owned by Mike Blyth. After working in many areas of the company he joined the marketing team and in 3 years became the head of the department. In 2000 he moved to California to run several aviation-related businesses in partnership with Mike Blyth, the founder of Sling / The Airplane Factory.Matt holds a Commercial Pilot rating in Airplane SEL and Private MEL as well as Glider and Weight-Shift Control (WSC). He is also a Flight Instructor in Airplane, Glider and WSC. Matt was selected as one of the early FAA Designated Pilot Examiners for Sport Pilot and maintains examiner authority in Airplane, Glider and WSC for both Pilot and Flight Instructor. His passion for aviation is broad and his favorite aircraft to fly are light airplanes and his aerobatic biplane. Matt is a member of various ASTM committees for Light-Sport Aircraft, is strongly involved in the aviation industry and is excited and proud to be able to help bring the aircraft of Sling to the US and to introduce aviation to more of the general public.โ I started flying over 30 years ago and have accumulated varied experience and ratings over the years. Aviation is my life and my work. To me aviation is the intersection of mind, body, and emotion. When you fly you need to have your mind clear and focused on managing and understanding everything that is going on around you with cold clarity. Physically, you need to manipulate the controls with coordination and precision. And then there is a great emotional response of awe and exhilaration at being able to project yourself in all 3 dimensions and gain perspective of the incredible world we live in. There is nothing else that I know of that engages every part of me all at once โ other than flying. And couple this to the fact that aviation is an endless source of learning and challenge, and you have a passion that will last a lifetime. Flying the Sling is as close to the dream of flying as Iโve ever imagined. Every day that I fly I feel like the luckiest person alive.โ
Jean d’Assonville
CO-CEO
Born in 1963 to a mother who was in the South African Air Force (SAAF) during the Second World War and a father who was technical wizard in all practical fields, he grew up loving aircraft and what made them fly. From an early age his father taught him the numerous mechanical skills underlying the creation of machines. By the age of eight he had designed, built and flew several model aircraft. By thirteen he was building and racing motorcycles which became his passion. At eighteen, he matriculated at Pretoria Boys High and was intimately involved in motorcycle racing both as a rider and as a mechanic. By modifying and maintaining motorcycles he made extra money and honed his mechanical skills.
Before serving his two year commitment in the SAAF, he enrolled at South African Airways (SAA) as a trainee aircraft technician with the aim of becoming a flight engineer. He was awarded the top student prize in all subjects including practical. At the age of 23 he bought his first semi complete home-built aircraft as an entry into aircraft building. He began learning to fly and loved it so much that he redirected his life to full time flying.
He started a flight school with a partner teaching students about flight by starting them on model aircraft, then handglides, then microlight aircraft, before putting them into heavier machines. At that time he became an Approved Person (AP-similar to US A&P/IA) for the inspection of tube and fabric aircraft in South Africa. In 1998 he bought and built a kit aircraft which caught the attention of the owner of Shadowlite Aircraft, a company which builds, distributes and supports the Jabiru aircraft in South Africa. This landed him the job of inspector and test pilot at the company. This led him to upgrade his AP privileges to include composite and aluminum airframes as well as wood and fabric. As the quality controller and test pilot at Jabiru for a period of eight years he supervised the building of, inspected and test flew over 200 aircraft.
Since September 2009 he worked on aircraft development and as the manager of production at Sling. His role has included structural testing of the aircraft, part improvement, flight testing and implementation and improvement of manufacturing procedures. In 2014 Jean moved to the USA to assist North American Sling customers.

Edward Hefter
CUSTOMER SERVICE MANAGER
Edward Hefter was born and raised in Central Florida and then spent a little over 5 years getting his 4 year engineering degree in Georgia. From there, he headed to California in 1992 for a few years, planning on moving back to the East Coast. That never happened, but 30 years of manufacturing, running a few businesses, raising a family, and getting bitten by the flying bug did happen.
His father took up flying after Edward left home, but when he took Edward on his first G.A. flight in his Cherokee 180 over Floridaโs Space Coast, he was hooked. Edwardโs father quit flying and was going to sell the Cherokee, so in 2019, Edward got his private pilotโs certificate, brought the Cherokee to California, and took many vacations and transported many animals with Pilots and Paws.
He got involved in Experimental Aircraft when complaining to a pilot friend about the price of a glass panel and autopilot upgrade for his Cherokee. His friend, who built his own Lindy-winning Velocity, convinced him to build his own plane rather than staying stuck in the Certified world. One demo flight in a Sling TSi with Jean and there was no turning back. Edward bought the empennage and soon bought the Quick Build kit, too.
During the build, Edward did some consulting for The Airplane Factory in Torrance and eventually convinced them to hire him. From there he embedded himself in TAF, with Sling in South Africa, and with all the fantastic customers that brighten his day. His Sling TSi was completed in 2024, just in time for Oshkosh, and has already flown family to vacations, pets for Pilots and Paws, and customers on their demo flights.
