Sudan Airways Flight 139 crashed near Port Sudan Airport during an emergency landing attempt, killing 116 of the 117 people on board.

Sudan Airways Flight 139 was a Sudan Airways passenger flight that crashed on 8 July 2003 at Port Sudan. The Boeing 737 aircraft was operating a domestic scheduled Port Sudan–Khartoum passenger service. Some 15 minutes after takeoff, the aircraft lost power in one of its engines, which prompted the crew to return to the airport for an emergency landing. In doing so, the pilots missed the airport runway, and the airplane descended until it hit the ground, disintegrating after impact. Of the 117 people aboard, 116 died.

Port Sudan New International Airport is an international airport serving Port Sudan. It is located 20 kilometres (12 mi) south of the city. The airport is the second-largest international airport in Sudan in terms of air traffic and international destinations served. Since 2023, the airport has been serving as the main gateway to Sudan due to the ongoing War in Sudan (2023).

An emergency landing is a premature landing made by an aircraft in response to an emergency involving an imminent or ongoing threat to the safety and operation of the aircraft, or involving a sudden need for a passenger or crew on board to terminate the flight. It typically involves a forced diversion to the nearest or most suitable airport or airbase, or an off airport landing or ditching if the flight cannot reach an airfield. Flights under air traffic control will be given priority over all other aircraft operations upon the declaration of the emergency.
