Libyan Arab Airlines Flight 1103 was a Boeing 727-2L5 with 9 crew members and 150 passengers on board that collided with a LARAF Mikoyan-Gurevich MiG-23UB on 22 December 1992.

Registered as 5A-DIA, it was manufactured by Boeing Commercial Airplanes in February 1975 and was delivered to Libyan Arab Airlines that same year.

At an altitude of 3,161 ft (960 m) above sea level, during the Boeing 727's approach to Tripoli airport, the aircraft's tail collided with a Mikoyan-Gurevich MiG-23's right wing and disintegrated, resulting in the deaths of all 159 passengers and crew.

[6] Twenty years later, after the fall and death of Muammar Gaddafi, Major al-Tayari, the instructor in the MiG-23 aircraft, challenged the official version of events, claiming that Flight 1103 was deliberately destroyed, because he saw its tail falling before his aircraft suffered a strong impact (from either the shockwave of the explosion that destroyed the Boeing 727 or a piece of wreckage) and he was forced to eject from his aircraft along with his trainee, Lieutenant Colonel Abu-Sneina.

[8] Ali Aujali, who served as a Libyan diplomat both under Gaddafi and under the subsequent National Transitional Council, claims that Gaddafi ordered that the Boeing 727, whose flight was assigned the number 1103, be shot down exactly four years to the day after the bombing of Pan Am Flight 103 in order to demonstrate the negative effects of international sanctions imposed on Libya.
