The National Transportation Safety Board is leading an investigation into a deadly airplane crash in the city of Sumner.

The pilot was killed when the crop duster went down Thursday around 7:30 AM, Sumner police said. They identified the victim as David Baker, 56, of Swedesburg, who was the only person on board.

According to officials, the plane hit the ground and burst into flames in front of a business along Iowa Highway 93 (West 1st Street). Witnesses told authorities that a wheel came off the low-flying plane when it hit a power line and knocked out electricity to part of the community. The wheel hit and shattered the glass front doors of a bank.

No other businesses were damaged and no one on the ground was injured, Sumner police said.
