Crashed An-12B was overloaded

The Antonov An-12B cargo aircraft crash at Entebe on 8 january 2005 killed the six Russian crew. The inquiry has identified overloading and engine failure as the cause of the accident, but also cites a culture of poor maintenance and inattention to safety oversight as contributory factors.

The aircraft (9Q-CIH) was registered in the Democratic Republic of Congo and operated by Uganda's Service Air. It crashed 5 Nm north of Entebe as it tried to turn back to the airport after an engine failure. Some 2 minutes later after take off, the crew reported to ATC that one of the starboard engine has failed and feathered. The aircraft contacted tall trees, stalled, crashed, desintegrated and was totaly destroyed with its cargo in the intense fire that ensued.

  • The aircraft trajectory was low and slow, with insufficient power from the remaining three engines, the aircraft was unable to maintain speed and altitude above the terrain.

  • The four engine turboprop was loaded beyond the safe weight and balance envelope (67,5 t for a MTOW of 61 t).

  • It needed 3,000 m ground run as opposed the 1,230 m given in the flight manual.
  • The flight data and CVR were recovered but they were not working.
  • The airline did not have and Air Operator's Certificate.
  • The Aircraft did note have a certificate of airworthiness.
  • The aircraft did not carry records of maintenance, Insurance, crew licensing and training, or quality control.

    The report recommends that all operators in Uganda airspace, even if licensed abroad, should meet the minimum safety requirements for Uganda permits...
