Two of four production conforming Honda Aircraft Company HA420 HondaJets made their public debut July 29 at EAA AirVenture 2013, showing progress in the program that is headed to certification next year.
“This is another milestone in the program,” says Honda Aircraft President and CEO Michimasa Fujino. In celebration, the two aircraft are scheduled to fly in formation 4:30 p.m. today at the air show, the first time serial number 3 and 5 have flown together in public.
Serial number 3 first flew in November 2011. It has full flight test instrumentation and is being used primarily for systems, flight control and nose wheel steering system development. The aircraft is capable of transmitting 4,000 channels of data in real time to Honda Aircraft’s flight test center.
Serial number 5 first flew in May 2013, and it has a production conforming interior, including cabin entertainment system and functioning aft lavatory. It will be used for cabin systems and options testing, plus functional and reliability testing just prior to certification.
Production HondaJets are 6 in. longer and several pounds heavier than initially planned partly because of copper mesh high intensity radiated fields and lightning protection embedded in the carbon fiber fuselage. They will full take advantage of the/Honda HF120 engine’s higher 2,095 lb. thrust rating.
Engine certification now is scheduled for the fourth quarter of 2013; aircraft certification is expected by the end of 2014.
