GENESEO, N.Y. (AP) — A pilot remains hospitalized with serious injuries suffered when his small airplane crashed at an upstate New York airport, leaving two teenage passengers with minor injuries.

The Livingston County Sheriff's Office has released the unofficial cause of a small plane crash at the Geneseo Airport on Friday. Officials say 65-year-old Timothy Sheffer flew his single-engine Cessna 172 off a runway at the airport, but had problems ascending.

Authorities say this caused the plane to crash and flip over. Sheffer broke his back in the crash and is still in Strong Memorial Hospital in Rochester. His two passengers, Civil Air Patrol cadets ages 14 and 15, were treated for minor injuries and released.

The official cause of the crash is still under investigation.
