A McDonnell Douglas MD-83, operating for Atlasjet Airlines as flight 4203, was destroyed after impacting high terrain near Isparta Airport, Turkey. All fifty passengers and seven crew members were killed.
Flight 4203 departed Istanbul-Atatürk Airport at 00:50 hours on a domestic flight to Isparta. The flight was cleared for a VOR/DME approach to runway 05. After crossing the IPT VOR beacon at the airport, the flight was supposed to have a course of 223°. At 12 DME, the aircraft then should have turned right onto runway heading.
However, the flight crew failed to program the arrival procedure into the FMS. After crossing the IPT VOR, the aircraft headed 253° and turned right over rising terrain. The EGPWS failed to sound as the aircraft flew towards the 1,830 metres (6,000 ft) tall Türbetepe hill.
The airplane impacted the top of the hill and broke up. The plane's wings and engines came to rest at the top of the hill while the fuselage was found 500 feet lower.

The investigation revealed that the EGPWS had failed repeatedly (86 times on the past 235 flights) and that it had been installed on another aircraft before being installed on TC-AKM ten days before the accident.
Additionally, it appeared that both flight crew members were inexperienced and lacked training. It was determined that the captain trained on the simulator for 20 hours instead of the mandatory 32 hours. The first officer attended simulator in Sofia for 32 hours, but these hours were not documented.
