The crew was engaged in a fumigation mission against locusts over plantation located near Jyl-Kol, in the Jalal-Abad Province. While flying at a height of about 15 metres, the aircraft hit power cables and crashed, bursting into flames. All three occupants were killed and aircraft was destroyed by post crash fire.
Probable cause:
In violation of Section 5.1.15 of the Guidelines for Aviation Chemical Works (ACW), the Aircrew Commander (AC) decided to combine the production flight with followed inspection of the new site, taking a representative of the Customer on board. In violation of Section 5, PPLS, the passenger was seating in the co-pilot seat and this is prohibited. Before making a decision to operate a flight, the Aircrew Commander received an indicative weather forecast from the hydro meteorology experts of Osh International Airport. The revised weather forecast was not drawn up and the crew did not receive it because the flight control officer did not send an actual weather data provided by the crew after take-off, in accordance with the requirements of paragraph 8.7.7, APKR-3 . The technology of air traffic controllers’ work at Osh International Airport does not include responsibility for the transfer of information about the actual weather obtained from the crews to base aerodrome meteorological office responsible for forecasting weather and it does not specifically define the actions of air traffic services in obtaining information about an aviation accident. No changes were made in the temperature regime when performing aviation chemical works in accordance with the Guidelines for the Implementation of ACW technology in Agriculture and Forestry” designed by the Civil Aviation Ministry, USSR, and issued on December 30, 1980, Number 668/Y (these instructions were entered into operation by the order of the Director of the Civil Aviation Department under the Kyrgyz Ministry of Transport and Communications on March 20, 2009, number 188/p in the “List of Legislative Acts Regulating the Civil Aviation Activities of the Kyrgyz Republic”). Portable emergency radio beacon, PARM -406, did not function at the time of the accident. The Statute of Aeronautical Search and Rescue Service of the Kyrgyz Republic has no changes related to its reorganization in 2007.

Circumstances:
The pilot, sole on board, was performing a crop spraying flight on behalf of the 'Svoboda' Agricultural Cooperation in the region of Chernolesskoye. While flying at a height of about 9 metres, trying to get altitude, the single engine aircraft successively collided with power cables and a concrete pylon, continued for about 99 metres then crashed in an open field, bursting into flames. The aircraft was destroyed by impact forces and a post impact fire and the pilot was killed.
Probable cause:
The accident occurred during crop-dusting flight due to late aircraft entry into climb for flying over PTL resulted in aircraft collision with power transmission line tower on a field under cultivation, followed by ground impact and fire. Probably late aircraft entry into climb was caused by PIC performance impairment (final crop dusting in final flight was performed after which PIC had to rest during 1,5 hours and short recreation cycle was disordered during flight operation), and also low-observability of PTL wires without day marking.

About 50 minutes into the flight, after it completed several low passes over the area to be treated, the engine lost power. The crew decided to return to Balota Aerodrome and completed a 180 turn when the engine stopped. The crew attempted an emergency landing in an open field. After landing, the aircraft rolled for about 130 metres when the left main gear collapsed and the airplane came to rest. All three occupants escaped uninjured and the aircraft was damaged beyond repair.
Probable cause:
Engine failure in flight due to fuel exhaustion. The following contributing factors were identified:
- Poor flight preparation on part of the crew who did not follow the pre-takeoff checklist,
- The checklist document was printed in an inappropriate format for the purpose for which it was intended,
- The aircraft was damaged beyond repair due to the nature of the terrain where the emergency landing occurred.

Circumstances:
The crew was engaged in a crop spraying flight on agricultural field in Vostochnaya, about 70 km northeast of Krasnodar. The day prior to the accident, the engine failed in flight and the crew made a forced landing in a field. As the carburetor was broken, it was replaced and an engine test run was performed. On 23 March, one minute after takeoff, while climbing to a height of 30 metres, the engine failed again. The crew attempted an emergency landing when the aircraft stalled and crashed in the Bakhotinski Lake, coming to rest upside down. The copilot escaped with minor injuries while the captain was killed. The wreckage was recovered three days later.
Probable cause:
The accident was caused by its nosing during the emergency landing on water surface. The emergency landing was caused by the engine power loss and flameout in the air due to the destruction of the exhaust collector can type combustor and burn through of the carburetor intake valve followed by high temperature burnt gases ingestion into the engine carburetor intake. The destruction of the exhaust collector can type combustor most probably occurred on the corrosion mechanism energized in conditions of the material heat during the engine operation using motor petrol. Power factor resulted in initial crack formation most probably was caused by residual tenses in the material of manufacture origine caused during can type combustor manufacture. In accordance with the passport the latest can type combustor overhaul was performed on January 27, 2009 in "Shakhtinsky ARZ DOSSAAF" CJSC. The commission didn't find the actual confirmation of the can type combustor overhaul as the marking at the single remained label indicates that the specified section had overhaul at the plant n° 420GA in October 1983.

The pilot was seriously injured and the aircraft was destroyed.
Probable cause:
The following findings were identified:
- The documentation was incomplete as there was no insurance certificat on board, no flying permit and no CofA,
- The flight was completed with one pilot only, without any copilot,
- The pilot failed to inform ATC and the Ukraine Army about the flight and did not receive any permission to perform the flight,
- When weather conditions worsened and the visibility dropped below minimums, the pilot failed to return or to divert to the alternate airport, continued and reduced his altitude until the aircraft impacted ground,

Circumstances:
The single engine aircraft was engaged in a local skydiving mission, carrying one pilot and 9 skydivers. Shortly after take off from runway 31, while climbing to a height of about 80 meters, the engine suffered a power loss. The pilot initiated a left turn to reach the airport when the aircraft rolled to an angle of 60° then stalled and crashed in a snow covered field near a forest, bursting into flames. The aircraft was destroyed by a post impact fire. Nine occupants escaped injured and a passenger was killed.
Probable cause:
Most probably the accident with and An-2 RA-33589 aircraft was caused by aircraft beyond stall angle of attack entry during dynamic turn for emergency landing with reverse runway heading due to engine failure after take-off at low-altitude followed by shaking and its power loss resulted in aircraft ground impact with bank angle more than 60°. Engine failure was caused by high-temperature damage and destruction of cylinder-piston group details due to it inadequate technical operation and using motor gasoline in aircraft fuel flow system which quality didn't comply with requirements for preferred AI-95 gasoline in accordance with aeronautical equipment flight service evaluation program, Order of Ministry of Transport of the Russian Federation № НА-131-р from April 11, 2001 and engineering solution № АБ-1236-2003 from May 22, 2003. Most probably the contributing factor was partial skill loss of An-2 aircraft control by aircraft pilot in command (PIC). Flight operation was performed by PIC, meteorological minimas and which authorizations written in Private-Pilot License and the fact of medical flight-expert commission procedure were not documented. PIC's decision to perform straight-ahead landing most probably didn't allow to reduce the severity of accident consequences.
