EASA Extends The CZIB Validity Until 31st March 2026.

Brussels; February 2026: European Union Aviation Safety Agency (EASA) has extended the Conflict Zone Information Bulletins (CZIB) validity till 31st March 2026, against the escalating tensions engulfing Iran and the adjoining territories.

This CZIB is issued based on information currently available to EASA, Member States and the European Commission in order to share information which is considered necessary to ensure the safety of flights over zones of interest and indicate areas of high risk. Given the ongoing situation and the potential for U.S. military action, which has placed Iranian air defence forces on a heightened state of alert, there is currently an increased likelihood of misidentification within the FIR Tehran (OIIX).

The presence and possible use of a wide range of weapons and air-defence systems, combined with unpredictable state responses and the potential activation of SAM systems, creates a high risk to civil flights operating at all altitudes and flight levels. Considering the overall high level of tensions, Iran is likely to maintain elevated alert levels for its air force and air defence units nationwide.

In the event of an US intervention, the possibility of retaliatory actions against its assets in the region cannot be excluded, which could introduce additional risks to the airspace of neighbouring countries where the U.S. military bases are located.

EASA, the Commission and Member States, will continue to closely monitor the situation, with a view to assess whether there is an increase or decrease of the risk for EU aircraft operators due to the evolution of the threat and risk situation.

The Affected Airspace are the All altitudes/flight levels in the airspace of Iran (FIR Tehran – OIIX). It is applicable for all the operators, namely Air operators:

• subject to the provisions of Commission Regulation (EU) 965/2012, planning to conduct operations in the affected airspace.

• third Country Operators authorised by EASA, when conducting operations under their TCO authorisation to, from and within the European Union.

Recommendation(s) – Air operators should:

• Not operate within the airspace of Iran, FIR Tehran (OIIX), at all altitudes and flight levels;

• Exercise caution and implement contingency planning for operations and routing planning within the airspace of neighbouring countries, in particular where the U.S. military bases are located;

• Closely monitor airspace developments in the region and follow all available aeronautical publications concerning the region, including information shared through the European Information Sharing and Cooperation Platform on Conflict Zones, alongside available guidance or direction from their national authorities.
