The families of pilots killed in a midair collision of a helicopter and gyrocopter at AirVenture in 2023 have filed a lawsuit against the Experimental Aircraft Association (EAA) alleging the accident was the result of the organization not following published FAA procedures for the airspace.
The accident happened on July 29, 2023, when both aircraft were operating in the EAA’s “Fun Fly Zone,” (FFZ), which consists of a grass runway in the ultralight display area of the EAA AirVenture show grounds at Wittman Field (KOSH) in Oshkosh, Wisconsin. In the area were ultralights, light planes, powered parachutes and trikes, hot-air balloons, homebuilt rotorcraft, and light sport aircraft (LSA).
