Emirates B777 crash at Dubai International OMDB

Emirates flight 521 crashes during a go-around at Dubai International, leading to immediate airfield closure.

2016-08-03 Dubai International Airport (OMDB), United Arab Emirates CW: Includes a major aircraft crash and fire. While all passengers survived, a firefighter was killed in the response.

Summary

On August 3, 2016, Emirates Flight 521, a Boeing 777-300, crashed while attempting a go-around at Dubai International Airport. The transcript captures the routine arrival phase, the sudden go-around call, and the subsequent chaos as emergency services rushed to the scene while other aircraft scrambled to divert.

Analysis

The recording begins with standard arrival procedures for Emirates 521 (EK521) coming from Thiruvananthapuram. The weather conditions included windshear reports, which are common in the heat of Dubai. After receiving landing clearance for runway 12L, the pilots of EK521 suddenly announced they were "going around." This is a standard safety maneuver where a landing is aborted to try again, but in this instance, the aircraft failed to gain altitude.

The technical cause of the crash involved a "state-of-mind" trap regarding the Boeing 777's autothrottle system. During the go-around, the pilots retracted the landing gear, but because the wheels had momentarily touched the runway, the autothrottle would not automatically increase engine thrust. The pilots, believing the automation was handling the climb, did not manually push the throttles forward until it was too late. The aircraft impacted the runway with its gear up, sliding on its belly and eventually catching fire.

A notable moment in the transcript is the Tower controller's attempt to hand EK521 off to the Departure frequency. This indicates that for a few brief moments, the controller may not have realized the aircraft had actually impacted the runway, likely due to the dust and heat haze common at OMDB. However, the tone shifts instantly as Fire Control takes over the frequency, shouting urgent instructions to "Proceed to the aircraft! Do not wait!"

The aftermath of the crash is captured through the communications of other flights, such as SkyDubai 848 and Syrian Air 515. These pilots are forced into holding patterns with dwindling fuel, eventually requesting diversions to Al Maktoum or Sharjah. While all 300 passengers and crew successfully evacuated the burning wreckage, the incident resulted in the tragic death of a firefighter, Jasim Issa Mohammed Hassan, during the emergency response. This recording serves as a stark reminder of how quickly a routine flight can transition into a major disaster.
