Emirates B777 crash was accident waiting to happen

 

The crash of an Emirates B777 during an attempted go-around in Dubai last Wednesday was always an accident waiting to happen.

It was not the fault of the pilots, the airline or Boeing, because this accident could have happened to any pilot in any airline flying any modern glass cockpit airliner — Airbus, Boeing or Bombardier — or a large corporate jet with autothrottle.

It is the result of the imperfect interaction of the pilots with supposedly failsafe automatics, which pilots are rigorously trained to trust, which in this case failed them.

First, let us be clear about the effect of hot weather on the day. All twin-engine jet aircraft are certified at maximum takeoff weight to climb away on one engine after engine failure on takeoff at the maximum flight envelope operating temperature — 50 degrees C in the case of a B777 — to reach a regulatory climb gradient minimum of 2.4 per cent.

The Emirates B777-300 was operating on two engines and at a lower landing weight, so climb performance should not have been a problem. I have operated for years out of Dubai in summer, where the temperature is often in the high 40s, in both widebody Airbus and Boeing B777 aircraft.

Secondly, a pilot colleague observed exactly what happened as he was there, waiting in his aircraft to cross runway 12L. The B777 bounced and began a go-around. The aircraft reached about 150 feet (45 metres) with its landing gear retracting, then began to sink to the runway.

This suggests that the pilots had initiated a go-around as they had been trained to do and had practised hundreds of times in simulators, but the engines failed to respond in time to the pilot-commanded thrust. Why?

Emirates 777 long-landed before idle-power go-around

 

Investigators have disclosed that the Emirates Boeing 777-300 destroyed in an accident at Dubai was attempting a go-around after a long landing.

The aircraft had touched down some 1,100m (3,600ft) from the threshold of runway 12L after a tailwind on approach started transitioning to a headwind.

General Civil Aviation Authority investigators state that, as the 777 touched down with its engines at idle power, the crew received an aural warning that the jet had landed long.

The crew opted to execute a go-around and the aircraft became airborne 4s after the warning.

Its flaps started to retract to the ‘20’ position – the normal go-around setting – some 4s after that, and the landing-gear lever was activated 2s later.

Crucially, the inquiry does not mention whether the take-off/go-around switch, normally used to command go-around thrust from the engines, was activated.
