Speaking to Tasnim, the CEO of the Civil Aviation Organization of Iran said the passenger planes of four countries are currently being repaired in Iran.
Mohammad Mohammadibakhsh declined to name those countries.
He said the Civil Aviation Organization is working with domestic knowledge-based companies to repair the plane components as part of the preventive maintenance programs.
A number of plane parts are being manufactured inside Iran in compliance with international standards, he added.
Last month, Iranian President Ebrahim Raisi issued an order to manufacture a homegrown passenger aircraft.
Pointing to his visit to Iran Aircraft Manufacturing Industrial Company (HESA), the president said he has ordered the experts at the factory to manufacture homegrown passenger planes with at least 72 seats in the near future.
In February 2021, the Civil Aviation Organization of Iran announced plans to launch the production line for Iranian 100-seater passenger aircraft.
