Our Aircraft’s History
Loral GZ-22 “Spirit of Akron” (C/S N4A; S/N 4120) ~ Originally built for the purpose of demonstrating the modern military capability of airships to the US Navy, this only version of the GZ-22 was originally designed by Goodyear but built by Loral after Goodyear withdrew from airship manufacturing. The GZ-22 had a steel framed and composite skinned gondola with a neoprene-impregnated polyester 2-ply envelope filled with helium. The GZ-22 Type Certificate was issued on 31 August 1989, designated the “Spirit of Akron”.
She flew for Goodyear for just over 10 years during the 1990’s, always a staple to the Northeast Ohio skyline.
On the evening of October 28,1999, the Spirit of Akron crashed in Suffield Township, Ohio, when it suddenly entered an uncontrolled left turn and began descending. The pilot and technician on board received only minor injuries when the airship hit trees. The NTSB report identified improperly hardened metal splines on the control actuators had sheared, causing loss of control and identified the probable cause as being failure by the “flight control system manufacturer to meet design (hardness) specifications”.
Goodyear donated the gondola and many of the parts to MAPS Air Museum. MAPS restoration crew went to work on the car. October 31, 2008, she was delivered to MAPS on a flat bed trailer. With the help of the movers, MAPS, and the airport it was unloaded and moved into the hangar where it sits now.
Museum display note: the “Spirit of Akron” retains the colors and markings as it flew during the 1990’s.

Goodyear donated the control car and many of the parts to MAPS Air Museum. Prior to coming to the museum, a MAPS restoration crew went to work on the car at the Wingfoot Lake Hangar. On October 31, 2008, the control car was delivered to MAPS on a flatbed trailer. The instrument panel did not have any instruments, though Goodyear gave us the instruments. They were soon placed in the panels and rewired. Power Supplies were added to power the instruments, radio, DVD player, LCD screen, audio amplifier, and lights.
