(SANDUSKY) — Two people were injured Wednesday morning after landing their small plane on the grass runway at the Sandusky Airport. According to the Sanilac County Sheriff’s office, the Piper J5A had touched down without issue and after traveling a short distance, an unknown issue caused the plane to veer off the runway into a large drainage ditch. The wing of the plane struck the opposite bank of the ditch and turned the nose of the plane straight into the ditch bank causing significant damage to the aircraft. Both the pilot, a 65-year-old Metamora man, and his passenger a 61-year-old man also from Metamora, were able to get themselves out of the airplane. They were taken to McKenzie Health System for treatment. The FAA was contacted and will be conducting an investigation in conjunction with the Sheriff’s office. The names of the pilot and passenger are being withheld pending an investigative determination.
