Read the full NTSB narrative
The pilot reported that he was on final approach when he experienced 'quick' and 'unexpected' altitude loss. The landing gear impacted a power line. The wire broke but the glider descended onto a road. No evidence of preimpact malfunction was discovered. The pilot wrote 'I question whether I actually retracted the spoilers. This may account for the excess loss of altitude.'
