GOVERNANCE · ICAO · TEN-DAY COUNTDOWN
The Council has had 36 seats since 1990. In ten days it will have 40. The instrument that did it sat unratified for nine years, then crossed its threshold in June. The vote arithmetic that governs every Annex amendment changes with it.

Quick Answers
| What is happening? | An Extraordinary Session of the ICAO Assembly (the 43rd Session) meets in Montréal on 19–20 November 2026 to elect four additional Member States to the ICAO Council. |
|---|---|
| Why now? | The 2016 Protocol amending Article 50(a) of the Chicago Convention entered into force on 12 June 2026, when Ecuador deposited the 128th instrument of ratification. The Council’s membership rises from 36 to 40. |
| Who can be elected? | Any of ICAO’s 193 Member States, elected within the three categories set by Article 50(b). Invitations were sent to all 193 on 3 July 2026. |
| Does this change any regulation? | Not directly. The election does not change any Annex text. But the Council adopts Annexes, and their amendments, and the two-thirds threshold moves from 24 votes to 27. |
| What about the Air Navigation Commission? | A parallel 2016 Protocol lifted the Commission from 19 to 21 members. Both Protocols took effect on the same date. |
| Does this affect my compliance obligations? | Indirectly, and over time. Council composition shapes which SARPs get adopted, how fast, and how State-specific concerns are reflected in the technical annexes your approvals depend on. |
| What is still unknown? | How the four seats will be distributed across the three Council categories. ICAO has not published a per-category allocation for this election. |
Quick Compliance Summary
- This is a governance event, not an airworthiness event. Nothing in your maintenance programme changes on 20 November. Do not let the headline imply an operational obligation.
- The compliance-relevant consequence is the vote arithmetic. Annex adoption requires two-thirds of the Council under Article 90(a). At 36 members, that was 24 votes. At 40 it is 27.
- The timing matters more than usual. Annex 19 Amendment 2 takes effect on 26 November—six days after the election. The body that will shape the next amendment cycle is being reshaped the week the current one lands.
- Watch the category split, not just the winners. Which party the four seats fall into determines whether the shift favours air-transport-weighted States, infrastructure-weighted States, or geographic representation.
- Note the co-location. ATConf/7 runs 16–20 November in the same building. Economic regulation and Council composition are being decided in the same week — a useful signal about ICAO’s near-term priorities.
- Re-baseline your State-level assumptions afterwards. If your approvals, validations, or bilateral arrangements depend on Council relationships, the map is about to be slightly redrawn.
Who Should Read This
Essential: Regulatory affairs and government-affairs teams at airlines, OEMs and MROs; State representatives and permanent missions to ICAO; compliance leaders whose approvals depend on Annex adoption timelines.
Important: Association and trade-body policy staff, aviation lawyers working on State-level implementation, and anyone tracking the Annex 19 Amendment 2 implementation gap across States.

What Happened
The amendment is nine years old and only recently came into force. ICAO members agreed to the change at Montréal on 6 October 2016, in a Protocol amending Article 50(a) of the Convention on International Civil Aviation. The Protocol did not take effect on signature. Like every amendment to the Convention, it required ratification by 128 Contracting States—two-thirds of the membership under Article 94(a).
It fell short of that number for years. In 2026, ICAO’s Legal Committee was still pressing the point, issuing a State letter on 4 May 2026 urging members to ratify. On 12 June 2026, Ecuador deposited its instrument and became the 128th State to ratify. Both 2016 Protocols took effect immediately: the Council moved from 36 to 40 Members, and the Air Navigation Commission from 19 to 21. ICAO’s own list of parties records 131 Contracting States as parties to the Article 50(a) Protocol.
ICAO invited all 193 Member States on 3 July 2026 and scheduled the election for 19–20 November 2026. The session is formally the 43rd Session of the Assembly, convened extraordinarily rather than as part of the triennial ordinary cycle.
Why the Election Needs an Assembly at All
Council Members are not appointed. Article 50(b) requires the Assembly to elect them, and it does so in three categories: States of chief importance in air transport; States which make the largest contribution to the provision of facilities for international civil air navigation; and States whose designation ensures that all major geographical areas of the world are represented.
That structure explains why the Council cannot simply slot in four new seats. The Assembly must fill each seat by voting in a specific category, and the categories carry different political weight. Part I elections turn on traffic and market size. Part II is on infrastructure and navigation-service contribution. Part III is where smaller States and regional blocs concentrate their campaigns — and where a four-seat expansion is most likely to be felt.
ICAO has not published a per-category allocation for the four additional seats in the material available ahead of the session. That gap is the key thing to watch on 19 November: the distribution will tell you more about the political bargain behind ratification than the winners’ names.
Why It Matters to Compliance Teams
Nothing in this election changes a single word of an Annex. But the Council is where Annex text becomes law in practice. Under Article 90(a), adopting or amending an Annex requires a two-thirds vote of the Council at a meeting. At 36 members, that threshold was 24 votes. At 40, it is 27.
Three votes is not a trivial shift. It means a blocking minority is harder to assemble at the margin and that a coalition needs broader support to carry an amendment. Annex amendments are rarely decided on a knife edge, but the ones that matter — new SMS obligations, information-security provisions, environmental standards, remotely piloted aircraft — are exactly the ones where a few votes of margin matter during drafting and consultation.
A second-order effect is easier to observe. Council Members sit on the committees and working groups that shape draft provisions before they reach the Council floor. A Council of 40 has more States with early sight of text, more drafting capacity in the room, and more opportunity for a State with a specific technical concern to raise it early rather than at the adoption vote. For an operator, that usually means more consultation and slower but better-tested amendments.
The timing is worth holding in view. Annex 19 Amendment 2 becomes applicable on 26 November, six days after this election. The Council overseeing the next safety-management amendment cycle is being reshaped in the same week the current cycle takes effect.

| Compliance / CAMO leadership | No operational change on 20 November | Do not conflate this with an airworthiness obligation in internal briefings |
| Trade associations | New points of engagement in the SARP drafting cycle | Refresh engagement plans for the 2027–2028 work programme |
| Aviation lawyers | Governance precedent for future Article 50 amendments | Note the nine-year ratification lag as a planning assumption |
| Consultancies / trainers | A teachable moment on how ICAO actually makes rules | Use it to explain the Council-to-Annex pathway to clients |
Checklist — What to Do Before and After 20 November
- Read ICAO’s session documentation for the four seats, including the category in which each is contested.
- Record the current 36-member Council list and the 2025–2028 term as your baseline.
- Note your own State’s position on the 2016 Protocols — whether it has ratified, and when.
- Check whether any existing approval, validation or bilateral arrangement depends on a Council relationship that may change.
- Confirm the election outcome and each new member’s category placement.
- Update your regulatory horizon scan to reflect a 40-member Council and a two-thirds threshold of 27 votes.
- Cross-reference the new membership against the Annex 19 Amendment 2 implementation timeline, which starts six days later.
- Do not issue any internal instruction that describes this as a compliance deadline. It is not one.

ARW Take
Most aviation compliance writing treats ICAO as a fixed backdrop. This month it is not. Two things are happening at once: the Council is expanding for the first time since the 1990 amendment took the membership to 36, and the safety-management annex that governs your SMS is about to become applicable in its third edition.
The expansion won’t change a single obligation in your operations manual. Be honest with your team about that. The value in watching it is predictive, not prescriptive: a 40-member Council with a 27-vote adoption threshold behaves differently from a 36-member Council with 24. Amendments will need broader coalitions, consultation will start earlier, and States with specific technical concerns will have more opportunity to shape text before it reaches a vote. That is, on balance, good news for the quality of the standards and mildly bad news for their speed.
The detail I would flag hardest is the nine-year gap between signature and entry into force. The Protocol was agreed in 2016 and only crossed its threshold in June 2026, after a direct push from ICAO’s Legal Committee. Anyone planning on the assumption that an ICAO amendment is live once it is agreed should recalibrate. Article 94(a) ratification thresholds are the real calendar, and they are long.
And a practical caution. This is a governance story with no operational deadline, which makes it easy to overstate in a headline and easy to dismiss in a compliance meeting. Get the framing right: the Council that adopts your future Annex amendments is being elected on 19 November, and the annex you are implementing right now becomes applicable six days later. Both facts belong in the same paragraph, and neither is a deadline.

FAQ
Does the Council expansion change any Annex or regulation?
No. The Protocols amend the Convention’s governance provisions, not the technical Annexes. No SARP text changes as a result of the election.
How many votes are needed to adopt an Annex amendment now?
Two-thirds of the Council under Article 90(a). At 36 members, that was 24 votes; at 40 members, it becomes 27. The threshold rises with the membership, so the proportion is unchanged.
Can the four new members start immediately?
They take their seats following election at the Extraordinary Session. The four join a Council that was elected at the 42nd Assembly for the 2025–2028 term; the session’s election documentation governs how the remainder of that term is treated.
Which category will the new seats fall into?
ICAO had not published a per-category allocation in the material available before the session. Article 50(b) sets the three categories: chief importance in air transport, contribution to air navigation facilities, and geographic representation.
Is my State affected?
Only if it is elected, or if your approvals and bilateral arrangements depend on relationships with States whose Council status changes. For most operators, the practical effect is indirect and slow-moving.
Why did it take until 2026?
Because Article 94(a) requires ratification by two-thirds of the Contracting States — 128 instruments. Ecuador deposited the 128th on 12 June 2026, after ICAO issued a State letter on 4 May 2026 pressing for ratification.
What else happened that week?
ATConf/7, the Seventh Worldwide Air Transport Conference, runs 16–20 November in Montréal, overlapping the Assembly session. Annex 19 Amendment 2 becomes applicable on 26 November.
