Comp Air continues to fly the Comp Air 12 proof-of-concept prototype while the company works with “potential investor groups and experienced engineering and production resource teams to execute the 36-month certification and production startup.” The large single-engine turboprop, powered by a 1,650-shp Honeywell TPE331-14GR, has undergone systems and handling characteristics tests and performance validations, according to Comp Air CEO Ron Lueck. Results of this testing will be used “to help optimize the final configuration for the first conforming/certifiable aircraft,” he said. While Comp Air is seeking investors to help finance the Comp Air 12 program, the airplane will begin the formal FAA certification program when the process of finalizing equipment standards and conforming aircraft specifications is completed.
