What happened
The aircraft touched down heavily on its left main landing gear. The pilot was conducting a VOR/DME-A circling approach while operating under instrument meteorological conditions. Environmental factors included icing and gusty winds. During the approach phase, the pilot observed ice accumulation on the airframe. In the final stage of the landing flare, the airplane experienced a premature stall before making proper contact with the runway surface.
The investigation
Examination of the event focused on the flight dynamics during the final approach and landing sequence. The primary mechanical outcome was significant impact damage to the left main gear due to the hard touchdown. No further mechanical anomalies were cited beyond the structural stress from the impact.
Findings
Contributing factors included the adverse weather conditions, specifically icing and gusty winds, which complicated the instrument approach. The premature stall during the flare phase was the direct cause of the hard landing. The pilot's assessment of airframe ice accumulation suggests environmental degradation of aerodynamic performance.
