Michael Meringolo came to Abaris Training in 2008 with over 27 years of composite experience. He began working with composites in the 80’s fabricating sand rail bodies using glass-fiber mat & polyester resin materials and construction methods.Kit Planes soon took his interest, as he went to work for an independent builder fabricating different aircraft from Burt Rutan’s Long EZ to the Lancair IV pressurized aircraft.In 1997, he began working exclusively at Lancair Kits in Redmond, Oregon. After a year of building gear-boxes for the Lancair kits, he transferred to the certified side of the company working primarily in Research and development for primary structures of this new high performance all composite four seater aircraft, building static and fatigue test articles, dealing with all testing and paperwork concerning certification of the aircraft. During this 13 years Michael took a short detour during his career to Scaled Technologies in Montrose Colorado, then quickly returned to Columbia Aircraft Manufacturing spending the next few years as their composite shop Production Manager.Through this experience, Michael gained knowledge in many areas of composites; from part-model and plug fabrication, to mold making, prepreg and wet lay-up, resin infusion, trimming & machining, surface preparation, composite bonding, and finishing. Michael’s background also includes lessons in composite theory and actual structural repair from his time with Lancair/Columbia (now Cessna). He was involved with the Lancair Tigress concept aircraft, the Legacy, as well as the evolution of the Columbia 300/350 and 400 models (now known as the Corvalis and Corvalis TT.Mr. Meringolo is a Professional Member of the Society for the Advancement of Material and Process Engineering (SAMPE). He has been awarded the prestigious NCATT certification for “Instructor Specializing in Aircraft Structures and Composites.” Michael also holds Industry-recognized CertTec® “Basic Composites Examiner” (CTE) Authority.

Lloyd Howden
Technical Instructor

Gregory A. Kress
Engineering Instructor

Randy Jones
NDI Instructor-ASNT Level III

Fernando Ricardo
Technical Instructor
Lloyd started his Aviation career in 1994 when he joined the U.S. Army, stationed at Ft. Campbell, KY with D Co. 2/160th (SOAR) working on MH-47E Helicopters, mostly repairing old rotor blades. After completing his service in 2000, Lloyd assisted the Dutch Royal Airforce with their new Chinooks. After 7 years of working with the Dutch, he took a job with Northrup Grumman on their MQ/RQ-5 “Hunter” UAV system, where he was the lead of the MOD/Revitalization team. It was here that Lloyd started teaching composite field repairs on structures while writing the repair manual for that system. Also, at Northrup Grumman, Lloyd worked on the MQ-4C “Triton” system, implementing composite changes and repairs to that system. In 2014 he moved on to Icon Aircraft where he took over the Composite Structure Bonding (CSB) Shop, where the team bonded together a 350 plus, fully composite A5 aircraft. In 2017 Icon moved to Mexico where Lloyd helped set up the shop to produce 1 aircraft every 2.5 days. Finally, before starting with Abaris in January 2019, Lloyd was the production manager with Volans-I, manufacturing 3 different composite unmanned vehicle systems. Lloyd brings much knowledge and skills to Abaris and is slated to teach both manufacturing and repair curricula for many years to come.
