A pilot and his wife from Tipp City walked away uninjured Thursday after their small twin-engine Piper crashed shortly after takeoff from Dayton International Airport.

James Mathias, 60, and Jennifer Mathias, 58, took off in their 1963 propeller-driven Piper PA-30 at about 9:43 a.m. when it stalled after climbing 50 feet to 100 feet and crashed in a grassy field 200 feet from the runway, the Ohio Highway Patrol said in a statement.

The couple was headed to Urbana, said Terry Slaybaugh, airport director of aviation.

“They were very lucky to walk away,” Slaybaugh said.

The plane did not catch fire but sustained heavy damage to its landing gear, undercarriage and both propellers, patrol Lt. M.W. Nichols said.

There was a small fuel leak, which was handled by Dayton airport police and the airport fire department.

Federal Aviation Administration investigators were already on scene working at the Vectren Dayton Air Show. The crash was unrelated to the air show, according to the OSP.

The plane has been moved to a hangar at ASI Aviation as the FAA and the state patrol continue their investigation.
