Template:Infobox aircraft occurrence Aeroflot Flight 229 was involved in a fatal aviation incident on Sunday, 14 June 1953 near Zugdidi, resulting in the loss of all 18 occupants aboard an Il-12P aircraft operated by Aeroflot.

Aircraft

The aircraft, an Il-12P bearing registration CCCP-Л1375 (factory number 30103, serial number 103), was produced on September 28, 1947 at the "Znamya Truda" facility in Moscow. Following manufacture, it was assigned to the Main Directorate of the Civil Air Fleet, which allocated it to the Georgian territorial administration’s 112th combined aviation detachment based in Tbilisi. By the time of the accident, the plane had logged a total flight time of 3,204 hours.

Accident

Flight 229 was scheduled to operate a passenger route from Moscow to Rostov-on-Don and onward to Tbilisi. The departure from Vnukovo Airport occurred at 05:20. The segment to Rostov-on-Don proceeded without incident. Afterward, the aircraft continued toward Tbilisi. Official records indicated that there were 10 passengers and 6 crew members onboard, totaling sixteen individuals. However, investigations revealed two additional unauthorized passengers: an eight-year-old girl, daughter of the chief engineer for the Georgian territorial civil air fleet administration, boarded in Moscow; and a co-pilot from an Li-2 aircraft within the same administration who embarked at Rostov-on-Don.

Thunderstorms affected the route between Krasnodar and Sukhumi. At 10:48, due to adverse weather conditions, the crew made an unscheduled landing at Pashkovsky Airport in Krasnodar. After monitoring weather improvements, they resumed flight at 15:02 toward Tbilisi. Upon entering Tbilisi Regional Air Traffic Control's airspace at an altitude of 2,400 meters at 16:02, communications continued normally. At 16:17, Flight 229 reported passing over Sukhumi Airport, followed by confirmation at 16:23 that it had exited that airport’s controlled zone. At 16:31, the crew informed Tbilisi ATC that they had passed Sukhumi at 16:17 and were flying between cloud layers. No further radio contact was established after this transmission.

The crash site was located precisely along the planned route on a wooded incline near Grigolishi (now known as Alertkari), approximately 15 kilometers northeast of Zugdidi. The accident resulted in total fatalities among all eighteen individuals onboard; notably, two passengers were ejected from the aircraft while it was flying at a low altitude. This tragedy represented the deadliest aviation catastrophe recorded in Georgia up to that time.

Investigation

The inquiry uncovered that thunderstorms along the Krasnodar to Sukhumi segment, which had compelled Flight 229 to make an unscheduled halt in Krasnodar, persisted between 7:00 and 13:00 hours. Subsequently, thunderstorm activity began to develop rapidly across various points on the Sukhumi — Kutaisi — Surami corridor. Notably, a thunderstorm was recorded near Zugdidi at 16:15 and later near Kutaisi by 17:30. The AMS issued a forecast predicting thunderstorms from 16:00 to 19:00 along the route from Sukhumi to Tbilisi, particularly between Mikha-Tskhakaya and Kutaisi. Despite this, the flight operations supervisor at Sukhumi Airport underestimated the worsening weather conditions between Sukhumi and Kutaisi and permitted the Il-12 aircraft to traverse the airspace and proceed toward Tbilisi.

Eyewitnesses reported a severe thunderstorm featuring hail, intense rainfall, and frequent lightning strikes in the crash vicinity. The flight crew was caught unprepared for such weather, leading to an unexpected encounter. It is plausible that a lightning strike partially incapacitated the crew, resulting in loss of control where the aircraft either entered a dive or an uncontrolled descent. During this descent, the pilots regained partial control and attempted to avoid impact by sharply pulling back on the controls at approximately 300 meters altitude to raise the nose. This abrupt maneuver generated excessive aerodynamic stress surpassing critical limits, causing structural failure as the outer wing sections between ribs 9 and 14 (beyond the engines) detached. With substantial wing loss, sustained flight was impossible; consequently, the fuselage, engines still running, plunged vertically to the surface where it was destroyed by impact and fire. The separated wing fragments fell roughly 120 meters away from the main wreckage and were spaced about 50 meters apart.

Conclusion

The commission determined that the crash's direct cause was the aircraft's inadvertent penetration into thunderstorm clouds. This event was exacerbated by procedural breaches from the Sukhumi Airport flight operations manager, who was aware of significant weather deterioration along the route but failed to mandate Flight CCCP-Л1375’s landing or warn its crew of thunderstorm risks. Additionally, the Sukhumi controller neglected to notify counterparts at Tbilisi regional center about the aircraft’s passage or seek instructions regarding its onward journey. At Tbilisi Airport, flight operations management also faltered by lacking accurate knowledge of weather conditions between Sukhumi and Tbilisi and neglecting to request updated forecasts from Tbilisi AMS for that segment. Despite awareness that two flights had been delayed due to adverse weather, Flight 229 received only a procedural clearance to enter Tbilisi regional air traffic control zone at an altitude of 2,400 meters under visual flight rules, without further navigational support. Communication deficiencies existed between Tbilisi’s flight operations manager and AMS weather station; while air traffic controllers obtained weather updates with delays, AMS staff remained uninformed about incoming flights through Tbilisi’s airspace.

Responsibility for the accident was attributed to flight operations managers at both Sukhumi and Tbilisi airports along with Sukhumi airport’s manager—each had authority but failed to prevent Flight 229 from transiting their controlled airspace.

Rumors

Following the incident, numerous speculations emerged. Some accounts suggested that a messenger carrying directives from Lavrentiy Beria intended for the Georgian authorities in case of a coup was among the passengers. Other reports claimed that several covert millionaires, transporting substantial amounts of money, were aboard this particular flight.
