[3] In the aftermath of that accident, President Salva Kiir banned aircraft greater than 20 years of age from operating passenger flights.
[1] Eyewitnesses report that the aircraft suddenly lost power[citation needed] and crashed in the Hai Referendum residential area.
According to South Sudanese Transport Minister Madut Biar Yol there were five crew members, all Russian nationals.
[9] South Sudan's Aircraft Accident Incident Investigation Department (AAIID) was unable to establish the cause of the crash, but determined that the flight violated regulations, as the plane lacked a valid airworthiness certificate and South West Aviation did not hold an air operator's certificate.
[1][10] South Sudanese president Salva Kiir called upon the Ministry of Transportation to "adhere to international standards" when assessing the airworthiness of aircraft adding "I know that it is hard to cope with the tragedy of this nature, but let us work hard to find the cause of this accident and use the lessons learned from it to prevent the occurrence of similar tragedies in the future".
