Iran Air's Only Boeing 747 Grounded for First-Ever Heavy Maintenance in Iran After Hitting 20,000-Cycle Threshold
Why It MattersThe grounding shows how a single aging freighter, constrained by parts supply and finance, can set the limit on a sanctioned airline's long-haul cargo capacity.
Iran Air has confirmed that its sole Boeing 747, a 747-200 Combi registered EP-ICD, has been grounded for heavy maintenance, including a D-Check, after reaching the threshold of 20,000 flight cycles. It will be the first time such heavy maintenance has been carried out in Iran. CEO Taher Abdolhai made the plans public on Telegram after a press conference last week. Work began in late September, and the aircraft is expected to fly again in 2026.
Abdolhai initially estimated 1.5 to two months of work, but an updated Iran Air schedule puts the timescale closer to six months. He said Iran Air faces fleet limitations, accumulated debts and a reduction in international routes, and that returning grounded aircraft to service and expanding flights depend on parts supply, financial resources and compliance with safety requirements.
EP-ICD, 38.1 years old, first flew in September 1988 and had logged about 86,039 flight hours across 17,320 cycles by the time it left Martinair in late 2007. It entered service with Martinair as PH-MCF, flying either an all-cargo layout or one with 530 economy seats, and was also leased to Qantas for mixed passenger and cargo loads before Martinair went all-cargo in 2006. After leaving Martinair in October 2007, it briefly served Ankair as TC-AKZ in May 2008, then joined Iran Air as EP-ICD a month later. It is now configured exclusively for cargo.
In recent months the jet mainly flew between Tehran and Tianjin Binhai International Airport (TSN) in China, and also flew to Macau International Airport (MFM) several times in August. Following the US and Israeli attacks on Iran in late February, it was stored in Tehran until May 9, 2026, when its first flight took it to Yerevan (EVN). In September it operated only Tehran–Tianjin round trips, departing on September 9 and September 16, and it landed back in Tehran for the final time before maintenance on the morning of September 18, 2026.
