EASA CZIB CZIB-2017-07R20: Airspace of Yemen – Sana’a Flight Information Region

What to do

Air operators should avoid operating in the Sana’a FIR at all altitudes except for routes in the maritime part east of route B400, where caution is advised. Operators must continuously monitor updates from Yemen and neighboring states' aviation authorities and follow guidance from the European Information Sharing and Cooperation Platform on Conflict Zones and their national authorities. The advisory is valid until April 30, 2027, unless reviewed earlier.

Summary

The Airspace of Yemen – Sana’a Flight Information Region document is a safety information bulletin issued by EASA concerning the high-risk airspace over Yemen, specifically the Sana’a FIR (OYSC). It highlights that all altitudes and flight levels within this airspace are considered high risk due to ongoing military conflicts and the presence of advanced anti-aviation weaponry, except for routes in the maritime part east of route B400, where the risk is medium. This advisory applies to air operators subject to Commission Regulation (EU) 965/2012 and third country operators authorized by EASA.

What changed

This document extends the validity of the safety information bulletin until April 30, 2027, without any changes to the content or recommendations. It continues to emphasize the high risk of operations in the Sana’a FIR due to the security situation and recent missile and unmanned aerial system attacks by Houthi forces. The risk assessment and operational recommendations remain unchanged.

Why it matters

This information is critical for aviation professionals as it affects flight planning and operational safety for flights transiting or operating within Yemen's airspace. Operators must be aware of the elevated risk of missile and drone attacks, which could lead to misidentification and unintended engagement of civil aircraft. Compliance with this advisory helps ensure the safety of passengers, crew, and aircraft while maintaining regulatory adherence.
