Read the full NTSB narrative

THE FLT HAD PROGRESSED NORMALLY FROM CHAMPAGNE, IL. THE IFR FLT PLAN WAS CANCELLED AT LAMONI VOR AND THE FLT PROCEEDED VFR. ON FINAL APPROACH TO RWY 17, APRX 1 MILE FROM THE RWY, THE ALTIMETER SUDDENLY UNWOUND AND THE ACFT STRUCK TREES. THE ALTIMETER HAD FUNCTIONED NORMALLY UP TO THAT POINT. POST ACCIDENT INSPECTION OF THE ALTIMETER SHOWED BINDING OF THE 100 FOOT NEEDLE AT THE TANG. ONLY SLOW MOVEMENT OF THE NEEDLE PRODUCED A SIGNIFICANT PROBLEM IN BINDING. THE TESTING OF THE ALTIMETER PRODUCED A SIMILAR MALFUNCTION TO THAT EXPERIENCED BY THE PLT DURING THE APPROACH. THE LIGHTS OF THE ARPT WERE FUNCTIONING PROPERLY DURING THE APPROACH.
