It was the second plane crash near the airport in less than a month.
The fatality was confirmed by Mayor Mark Boughton, but the identity of the victim was not immediately released. Boughton said in a Twitter posting that the plane crashed next to the kitchen window of a 91-year-old woman who was not hurt.
"She's a tough old bird," the woman's son, Paul Valeri, told The Hartford Courant. "She came out and says she never heard a noise that loud in all her life."
The single-engine, propeller-driven plane went down shortly after 8 p.m. after losing contact with the tower at Danbury Municipal Airport, Federal Aviation Authority spokesman Jim Peters told The Courant.
The FAA said the plane was a single-engine propeller-driven aircraft - a Cirrus SR-22. The plane is registered to Cirrwood LLC., at 5650 High Drive in Mission Hills, Kansas.
The plane glanced off a house and knocked off a gutter, Danbury Fire Capt. Bernie Meehan told the newspaper.
On Oct. 1, another small plane crashed shortly after takeoff from the Danbury airport, landing about a mile away on a lawn in Ridgefield after clipping the tops of several trees. The pilot was treated for non-life threatening injuries.
