WALLINGFORD, Conn. — Federal transportation officials say the Connecticut doctor who died when the plane he was piloting crashed last month had purchased the aircraft just three weeks earlier.

Dr. Joseph Tomanelli, of Cheshire, was pronounced dead at the scene of the April 24 crash near Meriden Markham Municipal Airport in Wallingford. His son, 21-year-old Daniel Tomanelli, of Hamden, was hospitalized.

The National Transportation Safety Board in its preliminary report released Tuesday found no evidence of in-flight structural failure and no evidence of pre-crash problems with the propeller or engine.

The NTSB says Tomanelli had purchased the single-engine Cirrus SR22 just weeks before the crash. He had more than 1,200 hours of experience flying other aircrafts.

The plane crashed while the 56-year-old Tomanelli was practicing touch-and-go landings.

The report didn’t offer a possible cause.
