Asiana Airlines Airbus A350 Engine Issues Prompts Diversion

An Asiana Airlines Airbus A350 on route from Incheon International Airport (ICN) to Singapore Changi Airport was forced to make an emergency landing in the Philippines.

The aircraft registration number HL7579 was operating as flight OZ-751 with 310 people on-board. It was cruising over the South China Sea at 32,000 feet when the crew needed to shut down the right-hand engine.

Asiana flight OZ-751 diverted to Manila

The aircraft immediately descended to 23,000 feet and diverted to Ninoy Aquino International Airport (MNL) where according to the Aviation Herald it made a safe landing on runway six around 80 minutes after declaring the emergency.

Asiana Airlines are reporting that the crew had to shut down one of the A350-900s two Rolls-Royce Trent XWB engines due to a problem with the engine’s fuel system.

All passengers on the flight were taken to local hotels while a replacement aircraft was dispatched to take them on to Singapore. The replacement plane another of Asiana Airlines A350s registration number HL8362 arrived in Manila some 18 hours later to ferry the passengers on to Singapore.

Meanwhile, the affected aircraft is still on the ground in Manila more than 30 hours after arriving in the Philippines capital.

How long can the A350 fly on one engine?

Of course, nobody wants to be thirty-something thousand feet in the air and suffer an engine failure. The good news here, however, is that if it happens aboard an Airbus A350 you probably don’t have to worry.

When Airbus designed the A350 they made sure that in the event of an engine failure the jet could continue flying until a suitable airport to land could be found.

The A350 excelled at being able to fly on a single-engine and was granted permission to fly up to 370 minutes on one engine by the European Aviation Safety Agency (EASA).

Known as Extended-range Twin-engine Operational Performance Standards, or ETOPS, this is a rule that determines how far a twin-engine aircraft can be from a suitable airport in the event of an emergency. For the Airbus A350, ETOPS is rated at more than six hours, allowing the aircraft to fly any passenger route on the planet.

The maximum time the A350 can fly on a single-engine is six hours and ten minutes which is equivalent to 2,500 nautical miles (4,630 km).

Look out Korean Air

In other Asiana Airlines related news, Korea’s number two airline behind national flag carrier Korean Air is about to receive a rich investor while public and government support is waning for Korea Air following numerous scandals.

According to Forbes, local media in Korea is reporting that Hyundai Development and Mirae Asset Daewoo are likely to be selected to take a controlling interest in the airline following the sale of Kumho’s 31% stake.

Having been saddled with huge debts Asiana Airlines has not been able to keep up with other airlines in the region, but that could be about to change if the Hyundai led consortium’s bid is selected.

We will keep you updated on Asiana Airline’s developments and in the meantime, if you happened to be on flight OZ-751 we would love to hear about your experience in the comments section.

Are they pumping out these engines to fast now.
As RR, PW and GE are all having trouble with these larger engines now.
Maybe the metal isn’t curing enough to make it stronger.
The fuel problem with these RR cannot be the same problem as BA 777 that crashed at Heathrow Airport all them years ago.
When the fuel froze up when they were coming in to land and shut down the engines.

The clue is in the fact that they landed rather than continue. If the aircraft could carry on for 6hrs according to ETOPS rules and the problem actually was the RR Trent, it would have been far better for them to do so as there is a RR maintenance facility at Singapore. The fact they chose to get straight down tells you it was a software issue and they were frightened of losing the 2nd engine.

The twin-engine aircraft operating on 1 engine is in emergency, and must land at the “nearest suitable airport.”

Nate Dogg

Yes that is correct but continuing to Singapore is near and more suitable in terms of RR Engineers. British Airways have consistently ignored the ‘nearest suitable airport’ when they have had an engine out. They did a US to Heathrow with a 747 on 3 engines before now with plenty of “suitable airports” down below them.

Gary

look at that BA 747 that was on route to Australia that time.
When it lost all 4 engines at altitude from the volcanic ash over Indonesia I think it was.
After losing height they could restart the engines again.
Only to lose them after gaining height again.
Wander how these 2 engines would go if it happened to them.
Even though they are not aloud to fly near a volcano no more
But volcanic ash does speed out though.

Paul Proctor

Continuing on past a suitable airport with a shut-down engine might have occurred in past decades, but not today. That includes quads and trijets. Also BA.

Murray Henly

Any of these long-haul twins will fly on one engine… until this second engine also quits.

Day after day, airlines and passengers worldwide are rolling the dice with extended flights over water and uninhabited areas with only two engines. And one day, the dice will fall the wrong way.

The risk is being made worse by the constant drive to push engine materials, pressures and tolerances to the limit, in an endless fight to reduce CO2 emissions, in the naive and unfounded belief that we can control the climate.
