Who has jurisdiction over the flydubai incident?

LETTER: A reported cockpit assault aboard flydubai flight FZ1073 on Sept 30, 2026, may have begun as a violent confrontation at over 9,000 metres. Legally, however, its consequences stretch across three countries.

The aircraft left Dubai, was registered in the United Arab Emirates (UAE), and was flying through Saudi Arabian airspace when the alleged confrontation took place before making an emergency landing in Tabuk.

The Indian captain reportedly suffered serious injuries. The co-pilot was detained for investigation. The aircraft also reportedly entered a rapid descent before passengers and crew intervened.

The immediate questions are straightforward: What happened? Who was responsible? What caused the descent?

The harder question is: who has the legal authority to investigate and prosecute?

This is where international aviation law becomes particularly important. Saudi Arabia, the UAE and India each have a legitimate connection to the incident, but those connections arise from different legal principles.

Saudi Arabia has the most obvious territorial connection.

The alleged offence reportedly occurred while the aircraft was in Saudi airspace. Under Article 1 of the 1944 Chicago Convention, every state has complete and exclusive sovereignty over its airspace.

That gives Saudi Arabia a substantial basis for investigating what happened. The fact that the aircraft landed in Tabuk strengthens that position.

The suspect, witnesses and potentially important evidence are also within Saudi jurisdiction. But the UAE cannot simply be written out of the picture.

The aircraft was UAE-registered. Under the 1963 Tokyo Convention, the state of registration has jurisdiction over offences committed aboard its aircraft.

The 1971 Montreal Convention also requires states to establish jurisdiction over specified offences committed aboard aircraft registered in their territory.

In other words, the same incident can legitimately engage Saudi territorial jurisdiction and UAE aircraft-registration jurisdiction. That does not mean the two countries must compete for control.

The Lockerbie case offers a useful warning against simplistic conclusions.

Following the 1988 bombing of Pan Am Flight 103 over Scotland, Libya brought proceedings before the International Court of Justice against Britain and the United States.

In 1998, the ICJ confirmed jurisdiction under the Montreal Convention. But it did not determine an exclusive criminal jurisdiction for the bombing.

The lesson is important. International aviation law often operates through overlapping jurisdictional interests rather than a single rule declaring one state automatically supreme.

India adds another dimension. The injured captain is reportedly Indian.

International law recognises the passive personality principle, under which a state may, subject to its domestic law and international obligations, exercise jurisdiction over certain offences committed against its nationals abroad.

Yet, nationality alone does not automatically make India the lead investigating state. India's most immediate role is likely to involve consular assistance, protection of its national and cooperation in securing relevant evidence.

There is also an important distinction between criminal investigation and aviation safety investigation.

Under ICAO Annex 13, the state of occurrence generally conducts the technical investigation.

Saudi Arabia would therefore have a central role if the incident occurred within its territory or airspace, while the UAE, as the state of registration and operator, would have recognised participation rights.

This distinction matters. Determining why an aircraft descended is not necessarily the same legal exercise as determining whether a criminal offence occurred.

What should happen next? The answer should not be a jurisdictional contest.

Saudi Arabia should lead the territorial criminal investigation, while the UAE should exercise its rights as the aircraft's state of registration. India should provide consular and evidentiary assistance concerning the injured captain.

The three countries should coordinate access to cockpit evidence, flight recorders, medical records, crew statements and operational data.

Evidence must be preserved, procedures respected and any prosecution conducted according to the jurisdiction ultimately exercised under applicable law.

The flydubai incident is a reminder that modern aviation routinely crosses legal borders.

An aircraft can be registered in one country, operated from another, fly through the airspace of a third and carry nationals from many more. International aviation law therefore cannot depend on a simple winner-takes-all approach.

Its real test is whether states can exercise their legitimate jurisdiction while cooperating sufficiently to establish the truth and ensure accountability.

At over 9,000 metres, national borders may seem invisible. In law, they remain very real. The challenge is ensuring that those borders do not become barriers to justice.
