There were two people aboard and at least one of them was killed. The condition of the other person was not immediately clear.
The crash happened around 6:25 p.m. Monday near the Meriden and Wallingford municipal line. The single-engine plane went down about 100 feet from the runway at Meriden-Markham Airport.
The National Transportation Safety Board said it's aware of the accident but can't provide further information.
Two people were killed last week when a small plane crashed near Skylark Airport in East Windsor. The victims of that crash were identified Monday as 61-year-old Robert Plourde, of Ellington, and 51-year-old George Janssen II, of Vernon.
