Near stall and hard landing during missed approach in icing conditions (N68300)

What happened

The pilot reported that while descending and being vectored on the localizer approach, the airplane accumulated mixed but mostly clear ice. He executed a missed approach, subjecting the airplane to 'extended exposure to ice conditions.' On his next approach, the pilot stated that he experienced 'deterioration of performance resulting in a near ground stall and hard landing.'

The investigation

The investigation focused on the aircraft's condition during the final approach phase. The pilot noted mixed but mostly clear ice accumulation during the initial descent. This led to a decision to abort the approach, which resulted in extended time in the icing environment.

Findings

• The airplane accumulated mixed but mostly clear ice while descending on the localizer.
• The pilot executed a missed approach, leading to extended exposure to ice conditions.
• Performance deterioration occurred during the subsequent approach.
• The event resulted in a near ground stall and hard landing.
