EASA CZIB 2026-02-R1
Iran and neighbouring airspace
Summary
The document titled "Iran and neighbouring airspace" is a Conflict Zone Information Bulletin (CZIB) issued by EASA concerning all altitudes and flight levels within the Tehran Flight Information Region (FIR) in Iran (OIIX). It highlights increased risks to civil flights due to heightened military alertness and potential use of air-defence systems amid ongoing geopolitical tensions. This advisory applies to all air operators subject to EU Regulation 965/2012 and third country operators authorized by EASA operating to, from, or within the EU.
What Changed
This CZIB extends the validity of the advisory until 31 March 2026 without any changes to its content. It continues to emphasize the high risk of misidentification and potential threats to civil aviation in the Iranian airspace and surrounding regions due to the ongoing conflict and military activities.
Why It Matters
This advisory is critical for aviation professionals as it identifies a high-risk airspace where civil flights face significant safety threats from military actions and air-defence systems. Operators, maintenance organizations, and compliance teams must recognize the elevated risks and adjust their operational planning accordingly to ensure safety and regulatory compliance.
What To Do
Air operators should avoid operating within the Tehran FIR (OIIX) at all altitudes and flight levels. They must exercise caution and develop contingency plans for flights near neighbouring airspace, especially where U.S. military bases are located. Continuous monitoring of aeronautical publications and updates from national authorities and the European Information Sharing and Cooperation Platform on Conflict Zones is essential. The advisory is valid until 31 March 2026 unless reviewed earlier.
