Shortly after crossing the Swiss-German border, the aircraft, cruising at an altitude around 3000 metre on, encountered a thunderstorm, and while flying through it, experienced turbulence. The right wing eventually broke off; the plane fell into a forest near Tuttlingen, exploding into flames on impact.Swissair Curtiss AT-32C Condor II CH-170 19340727-0 February 17, 2014http://www.planecrashinfo.com/1934/1934-16.htm Accident Details Kebabjian Richard planecrashinfo.com Plane Crash Info 17 February 2014 Investigation Investigators found that oscillations in the wing had caused a stress fracture, the severity of which was exacerbated by the violent weather conditions in which the aircraft was flying. German investigators, however, determined that one fracture formed in the wing and engine-mount structure due to defective construction and welding techniques in conjunction with the engine vibrations, while a second fracture resulted from the force of the turbulence in the storm.
