(Reuters) – The United Arab Emirates’ (UAE) civil aviation regulator is investigating why an Emirates Airbus A380 superjumbo flew dangerously low when approaching Moscow’s Domodedovo Airport last week.

The General Civil Aviation Authority (GCAA) said its air accident investigation unit is treating the Sept. 10 episode as a “serious incident”, an internationally recognized category which means an accident “nearly occurred”.

The GCAA said Emirates flight EK131 “descended below the glideslope on approach”, meaning that the aircraft flew below the recommended height as it came into land.

The Aviation Herald reported that the aircraft descended to 400 feet at 8 nautical miles (14.8 kilometers) from the runway, before pulling out of the approach and later landing safely, but only after a second unsuccessful attempt.

The typical height for a passenger jet at that distance would be more than 2,000 feet, an aviation expert said.

The pilots told air traffic control “everything is fine” when contacted by operators after the incident, and later said “everything is great” following the second unsuccessful landing attempt, a Russian industry source with direct knowledge of the matter said.

No injuries to the 446 passengers and crew onboard or damage to the aircraft was reported, the GCAA said.

A spokeswoman for Emirates, which says it operates two daily flights to Moscow, confirmed the flight was under investigation, but declined to comment further.

Emirates has not raised any concerns about Russian air traffic control or airport equipment relating to the incident, Russia’s Rosaviatsia federal air transport agency said.

Flight information has been handed to the GCAA and the airline, the Russian agency said, adding that it was not conducting its own investigation.
