Allied Services Ltd — Flight Unknown

An Antonov An-12BK cargo plane crashed shortly after takeoff from Juba International Airport, impacting a hill and coming to rest on the banks of the White Nile. The aircraft was operating a domestic cargo flight to the Paloich oil fields and was carrying a large number of unmanifested passengers. Investigators and authorities cited severe overloading and the aircraft's lack of airworthiness as primary factors in the disaster. While two people (an adult male and an infant) survived the initial impact, a third person initially survived but later succumbed to their injuries in the hospital. Total fatalities include both those on board and individuals on the ground.

Report

Investigation Summary

The aircraft, a 44-year-old Soviet-era turboprop, was leased by Allied Services Ltd from Tajikistan's Asia Airways. Although registered as a cargo flight, it is common practice in South Sudan for security services and logistics companies to place family members and oil workers on such flights, often bypassing official manifests. On the morning of the accident, the pilot reported 12 passengers to Air Traffic Control, but recovery efforts revealed at least 37 passengers were on board. The aircraft struggled to gain altitude immediately after departing runway 13, traveling only about 800 to 1,100 meters before impacting terrain. The manufacturer, Antonov, later stated the aircraft was not airworthy at the time of the crash because the owner had failed to comply with mandatory technical servicing and life-extension procedures.

Final Conclusions

The crash was attributed to the aircraft being significantly overloaded, which prevented it from maintaining a safe climb gradient after takeoff. Contributing to the accident was the operation of an aircraft that had not undergone required maintenance to extend its service life, rendering it technically unairworthy according to the manufacturer.
