Template:Infobox aircraft occurrence Sun Way Flight 4412 was a scheduled international cargo service operating between Karachi, Pakistan, and Khartoum, Sudan. On 28 November 2010, the flight’s Ilyushin Il-76 suffered a catastrophic engine failure shortly after departure, prompting an attempted return to Karachi. The aircraft ultimately crashed, resulting in twelve fatalities: all eight crew members onboard plus four individuals on the ground. The failure was attributed to metal fatigue caused by operating the engine beyond its intended service life.

Video showing the aircraft engulfed in flames and subsequent crash

Flight 4412 took off from Jinnah International Airport in Karachi at 01:48 local time (20:48 UTC on 27 November), heading for Khartoum International Airport. The Ilyushin Il-76TD was transporting approximately 31 tonnes of humanitarian aid, reportedly including tents for Sudan. The flight crew consisted of eight personnel with Russian and Ukrainian nationalities.

Witness accounts indicated that one of the engines on the right wing ignited shortly after liftoff from Jinnah Airport. The aircraft subsequently crashed into partially constructed buildings within a residential complex designated for the Pakistan Navy, igniting several structures approximately 3 kilometres () from the runway threshold. Emergency responders verified four fatalities among individuals on the ground.

The explosion’s intensity led nearby residents to suspect a bomb detonation. Those who perished on the ground were reported to be construction workers.

Aircraft

The aircraft involved was an Ilyushin Il-76TD registered in Georgia as 4L-GNI, operated by the Georgian cargo airline Sun Way. It was reported that the airplane had undergone a comprehensive technical inspection within the two weeks preceding the incident.

Investigation

An inquiry into the accident was conducted by the Civil Aviation Authority of Pakistan. Findings revealed that the aircraft’s airframe and engines had surpassed their certified design life in 2004, which was seven years prior to the crash, and that operation continued without approval from the manufacturer. Additionally, the Il-76’s takeoff weight exceeded the maximum permissible limit of 190 tons by approximately five tons.

The investigation concluded that the accident originated from an uncontained failure of the second stage disk within the low-pressure compressor of engine number four shortly after liftoff. This failure was linked to metal fatigue, directly stemming from prolonged use beyond the engine’s intended design life.

Fragments expelled by the malfunctioning engine struck the right wing, causing damage to the flaps and puncturing fuel tanks. The resulting fuel ignition further compromised the wing and flight control systems, rendering the aircraft uncontrollable. Subsequently, it rolled sharply to the right before crashing.
