Sepehran Airlines aviation incidents in Iran

Overview

Sepehran Airlines has experienced two separate aviation incidents involving Boeing 737 aircraft at Mashhad International Airport.

On August 25, 2026, a Boeing 737-500 operating flight IS4310 from Tehran veered off the runway into an unpaved area after landing. All 127 passengers and crew were evacuated safely without injury. The Iran Civil Aviation Organization launched an investigation into the excursion, which resulted in the temporary closure of Runway 13R and Taxiway Q.

On September 15, 2026, a Boeing 737-300 traveling from Mashhad to Kermanshah was forced to perform an emergency landing back at Mashhad Airport. While initial reports suggested a tire burst caused engine damage and debris, a subsequent investigation by the Iran Civil Aviation Organization identified the cause as an abnormal oscillation known as ‘Shimmy’ in the main landing gear. The investigation found that the Shimmy Damper was in poor condition due to ‘leakage, wear, and corrosion,’ which transmitted abnormal forces to other landing gear components. This caused intense vibrations, leading to detached ceiling panels and open overhead storage compartments.

All passengers escaped the September 15 incident without injury. These events have raised significant concerns regarding aviation safety and maintenance in Iran, particularly as sanctions complicate the acquisition of authentic spare parts for aging fleets. Sepehran Airlines’ Boeing 737 models have an average operating age of approximately 32 years.
