Crashes during testing
February 1989
On 2 February 1989, the first prototype JAS 39-1 crashed on its sixth flight, when attempting to land in Linköping. The accident was filmed in a now famous recording by a crew from Sveriges Television's news program Aktuellt.[1] The pilot, Lars Rådeström, remained in the tumbling aircraft, and escaped with a fractured elbow and some minor injuries. The crash was the result of pilot-induced oscillation (PIO). Extremely gusty winds also contributed.[2]
August 1993
On 8 August 1993, a production JAS 39A Gripen (serial number 39-102[2]) crashed on the central Stockholm island of Långholmen, near the Västerbron bridge, when the aircraft stalled after a slow speed manoeuver during a display over the Stockholm Water Festival. The crash was, like the first one, caused by pilot-induced oscillation, and caught on film.[3] The pilot – Rådeström again – ejected from the aircraft, and landed safely by parachute, though he became stuck in a tree. The aircraft fell to the ground and caught fire on impact. Despite large crowds of onlookers, only one person on the ground was injured,[a] and the fire was soon put out.
The aircraft had been delivered to the Swedish Defence Materiel Administration in June, only two months prior to the crash.[2] The display flight was not classified as in-service, because it was being flown at a display by a test pilot, rather than a Swedish Air Force officer.
