Unfallbericht:
The Stavropol aircraft took off from Stavropol Airport for a flight to Trabzon. 37 Minutes after takeoff, while cruising at FL197, the Antonov lost altitude and crashed into a forest. Wreckage was scattered across a 2 mile area. The tail section was found a mile away from the main wreckage. It appeared that massive corrosion of the fuselage (30th to 34th bulkhead) had caused the tail section to separate. The aircraft had been operating in humid weather conditions within Congo for 16 months.
PROBABLE CAUSE: "The accident was caused by a combination of the following factors: the superficial mechanical inspection of the aircraft which was carried out without the use of monitoring instruments, and the subsequent unjustified decision to extend the time between overhauls and the service life; violation of requirements in force by extending the overhaul life of the aircraft without taking maintenance as regards determination of the degree of corrosion and corrosion fatigue in hard-to-reach areas of the aircraft; inadequate monitoring in operation to determine the state of structural elements and detect the presence of corrosion in hard-to-reach areas under the floor of the fuselage; failure to carry out prescribed anti-corrosion measures on the aircraft structure during overhaul at the maintenance center and in operation."
