Interim Statement
This first anniversary Interim statement gives a brief account of the progress of the
Investigation into the subject Accident. The statement is released in accordance Standard 6.6 of ICAO Annex 13 and paragraph 7.4 of UAE CAR Part VI, Chapter 3.
The Accident occurred on 3 August 2016 and involved an Emirates Boeing 777-300
Aircraft, registration A6-EMW, operating a scheduled passenger flight EK521, that had
departed Trivandrum International Airport (VOTV), India, at 0506 UTC for Dubai International Airport (OMDB), the United Arab Emirates. At approximately 0837:38 UTC, the Aircraft impacted the runway during an attempted go-around at Dubai International Airport.
The Aircraft sustained substantial structural damage as a result of the impact and its
movement along the runway and was eventually destroyed by fire. Twenty-one passengers, one flight crewmember, and four cabin crewmembers sustained minor injuries. Four cabin crewmembers sustained serious injuries. Approximately nine minutes after the Aircraft came to rest, a firefighter was fatally injured as a result of the explosion of the center wing fuel tank.
Regarding the operation of the flight the Investigation is working to determine and
analyze the human performance factors that influenced flight crew actions during the landing and attempted go-around.
In addition, the Investigation has reviewed and has identified safety enhancements
related to the validity of weather information that was passed to the flight crew, and
communication between air traffic control and the flight crew.
A detailed examination was performed of the Aircraft evacuation systems, including
the operation of emergency escape slides in a non-normal aircraft resting position, and the effects of wind on the escape slides.
A large number of aircraft systems were tested with the assistance of the manufacturers and analysis of the data downloaded indicates that there were no Aircraft systems or engine abnormalities up to the time of the Accident.

The UAE GCAA Air Accident Investigation Sector continues to collaborate with the
State authorities and other organizations involved in areas of interest including flight
operations, human performance, training standards, procedures, aircraft systems, passenger evacuation and airport emergency response.
