Investigation Summary
The aircraft was transporting 68 journalists and media personnel to cover military exercises in the Persian Gulf. Approximately eight minutes after departure from Mehrabad International Airport, the flight crew reported technical issues with the number 4 engine and requested clearance to return. During the subsequent ILS approach to runway 29L, the aircraft lost altitude and struck the 'Towhid' residential complex in the Azari district, approximately 2 kilometers from the runway. The impact and resulting fire destroyed the aircraft and caused significant damage to the apartment block, which housed air force personnel and their families. Visibility at the time was reported as 1,500 meters due to heavy smog, which may have hindered the crew's ability to maintain visual reference during the emergency landing attempt.
Final Conclusions
The accident was initiated by the failure of the number 4 engine. While the official investigation by the Iranian military was not fully transparent to international bodies, the crash is widely attributed to a combination of mechanical failure and the challenges of maneuvering a heavy transport aircraft on three engines in a high-density urban environment with poor visibility. The incident highlighted the aging state of Iran's C-130 fleet, which had faced maintenance difficulties due to long-standing international sanctions affecting the procurement of spare parts.
