Weather Briefing and Initial Flight
Approximately one hour prior to departure, the pilot received a weather briefing that included a forecast for 'a chance of light icing'. About 30 minutes after takeoff, while cruising at 6,000 feet MSL, the aircraft encountered light rain. The pilot observed a small amount of ice forming on the strut and requested a climb to 8,000 feet MSL.
Encounter with Heavy Icing
Air traffic control cleared the aircraft to climb above the cloud layer. However, heavy icing began to accumulate, and the aircraft could not climb above 7,300 feet MSL. A descent of 300 to 400 feet per minute developed, and the aircraft was cleared via radar vectors to Dalton, Georgia.
Landing Incident
During the approach, the pilot reported, 'Suddenly, at a height of approximately fifty feet above the runway, the aircraft seemed to veer as though left rudder had been applied, although the rudder pedal had not been moved.' The aircraft then contacted the ground heavily, collapsing the nose gear.
Post-Accident Observations
A witness noted approximately 3/4 inch of ice on the leading edge of the wings, 1/2 inch on the fuselage, and about 1 inch on the belly of the aircraft. It was also determined that the aircraft was loaded approximately 200 pounds over gross weight.
Aircraft Registration
The aircraft involved was registered as N91625.
