Aircraft involved
Probable cause & findings
THE PILOT-IN-COMMAND'S DECISION TO INITIATE FLIGHT INTO KNOWN ICING CONDITIONS WHICH RESULTED IN AN ACCUMMULATION OF AIRFRAME ICE. THE ICING CONDITIONS AND THE PILOT'S DISREGARD OF THE WEATHER ADVISORY WERE FACTORS.
Factual narrative
THE INSTRUMENT FLIGHT INSTRUCTOR OBTAINED A PREFLIGHT WEATHER BRIEFING DURING WHICH HE WAS ADVISED THERE WERE REPORTS OF LIGHT RIME ICE. THE PILOTS TOOK OFF FOR A LOCAL FLIGHT TO PRACTICE APPROACHES. BOTH PILOTS REPORTED THEIR APPROACH BACK TO THE AIRPORT APPEARED NORMAL UNTIL THE STUDENT BEGAN TO FLARE. THE AIRPLANE '...JUST SEEMED TO QUIT FLYING AND SANK RAPIDLY TO THE RUNWAY.' THE RIGHT MAIN LANDING GEAR SEPARATED FROM THE AIRPLANE AT GROUND IMPACT. THE AIRPLANE SKIDDED TO A STOP ON THE RUNWAY. POST-ACCIDENT EXAMINATION REVEALED ACCUMULATIONS OF ROUGH RIME ICE BETWEEN 1/2 AND ONE INCH THICK ON LEADING EDGES, ETC. THE INSTRUCTOR REPORTED HE NOTED ICE ACCUMULATING ON THE WINDSHIELD, BUT ADDED HE WAS NOT CONCERNED BECAUSE THE AIRPLANE 'COULD HANDLE LIGHT ICE VERY WELL.' THE INSTRUCTOR STATED THE AIRPLANE STALLED ABOUT 16 MPH FASTER THAN PUBLISHED STALL AIRSPEED. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
