A Sky Express Avions de Transport Regional ATR-42-500, registration SX-FOR performing flight GQ-405 from Naxos to Athens (Greece) with 46 passengers and 3 crew, was backtracking runway 36 for departure at about 17:20L (14:20Z) when the aircraft went off the paved surface of the runway and came to a stop with the main gear in a ditch, the tail on the ground, the lower fuselage below propellers on the runway edge and the nose gear on the runway surface. There were no injuries, the aircraft sustained substantial damage.

Passengers on previous flights reported it was common to backtrack the runway, line up for departure and then roll back using back power (propellers in beta) to get as much runway available for takeoff as possible.

On Aug 2nd 2019 Greece's AAIASB reported the aircraft was backtracking runway 36 for departure. After turning around to line up runway 36 for departure the main wheels of the aircraft reached the end of the runway and stopped off the runway. The aircraft sustained substantial damage. The occurrence was rated an accident and is being investigated.

On Oct 11th 2019 The Aviation Herald received information from a passenger on the flight, who told the Aviation Herald:

During the backing up procedure, the plane kept accelerating until it fell off. It was not slowing and the engines were revving at the same apparent RPM until the crash.

Immediately after we bottomed out and came to stop, the pilot revved the engines in an apparent attempt to pull us back onto the runway. This was very disconcerting (more so than the impact) because it was clear to me that the plane was badly damaged. I was concerned that a propeller could strike the runway and create a much more dangerous situation. As we can see in the pictures (which I could not see from my window) is that the propellers had plenty of ground clearance.

After that plan failed, the pilot cut the engines and came out to open the rear door. He and the flight attendant opened the back door, looked out and closed it again. They conferenced and he went back into the cockpit. The flight attendant then announced that there was a mishap (Really?), we were safe, and that they had determined that we could not evacuate from the back (door with stairs attached) due to a barbed-wire fence directly under that door. She told us that the pilot was calling for stairs so we could use the front door (the step stool you can see in the photos). The pilots said nothing at all to us, ever.

Naxos' runway 18/36 is officially 900 meters/2950 feet long. The Hellenic AIP reports TODA, TORA, ASDA and LDA all at 900 meters.
