An An-26 twin-engined turboprop military transport aircraft of the Ukrainian Armed Forces crashed near Chuhuyiv, Kharkiv Region at around 9 p.m. on 25 September. Twenty-five people, most cadets of the Kharkiv Ivan Kozhedub Air Force Academy, were killed on the spot. Two cadets managed to get out of the plane, but one of them succumbed to wounds in a hospital.
The only remaining survivor, cadet Vyacheslav Zolochevskyy, had no major injuries and is recovering, according to doctors.
According to Defence Minister Andriy Taran, the aircraft wing touched the ground after a sensor in its left engine failed. Manufactured in 1977, the aircraft had 5,000 flight hours before the next scheduled engine maintenance.
The State Investigation Bureau is considering four versions behind the crash: technical failure of aircraft units, improper implementation of duties by the crew or a flight commander, improper technical maintenance or preparation for flight.
Flight recorders have been retrieved from the plane.
