Flight Details
A certified instrument flight instructor and a student pilot conducted a local flight to practice instrument approaches. Prior to departure, the instructor obtained a preflight weather briefing that included reports of light rime ice. Despite the advisory, the flight proceeded as planned.
Accident Sequence
Both pilots reported that the approach back to the airport appeared normal until the student pilot began the flare. At that point, the airplane "just seemed to quit flying and sank rapidly to the runway." The right main landing gear separated upon ground impact, and the airplane skidded to a stop on the runway.
Post-Accident Examination
A post-accident examination of the airplane revealed accumulations of rough rime ice measuring between one-half and one inch thick on the leading edges of the wings and other surfaces.
Pilot Reports
The instructor reported that he noticed ice accumulating on the windshield during the flight. However, he stated that he was not concerned because the airplane "could handle light ice very well." According to the instructor, the airplane stalled at a speed approximately 16 mph faster than the published stall airspeed.
