Sometimes CTRL-ALT-DEL also cannot work, have to use hard reset...

[Ignatius 4]

I wonder how to hard reset a T7?? Press reset and power button together for 2 sec?? hehehe, then waiting it to reboot, alamak... by the time its windows is fully loaded, all the cockpit windows and cabin windows all already shattered hehehe

Boeing 777s had six other engine failures

The type of aircraft that crash-landed at Heathrow last week has had six other engine failures logged by American investigators, The Daily Telegraph can disclose.

 

Details of the incidents involving Boeing 777s emerged as officials from the Air Accidents Investigation Branch try to uncover the reasons behind last week's accident involving British Airways flight 038 from Beijing.

 

The earlier failures were logged by the US National Transportation Safety Board, which has an investigator working with the AAIB. It has been established that the two engines on the BA jet failed to produce the thrust needed as the plane, with 136 passengers on board, came in to land.

 

At first it was thought that the aircraft suffered a catastrophic double engine failure but it has since emerged that one engine was still turning even after the plane hit the ground.

 

This makes the findings of the previous incidents of crucial importance as they all refer to single engine problems.

 

These are the previous incidents:

 

• Aug 2 2005: The greatest interest is likely to be in an incident when a Malaysian-registered 777 suffered a loss of thrust while climbing half an hour after take off from Perth before returning and landing safety.

 

Australian investigators identified computer failings which led to the pilots being given inaccurate speed readings and the US Federal Aviation Administration in Washington ordered a computer upgrade, warning that faulty data could cause difficulties with the flight controls, autopilot, pilot displays, brakes and autothrottles.

 

The preliminary AAIB report into last Thursday's crash-landing pinpointed problems with the autothrottle as one of the factors which triggered the emergency.

 

• July 1, 1998: An Air France plane en route to Paris from Sao Paolo suffered an "uncommanded engine shutdown". Investigators identified oil pump contamination as the cause.

 

• Jan 30, 2001: A United Arab Emirates 777 suffered an engine failure as a result of a defective fan blade. Investigators identified fatigue cracking as the cause.

 

• June 6, 2001: A Thai Airways 777 suffered a ruptured fuel tube en route from Taipei to Bangkok.

 

• June 23, 2005: A Japan airlines 777 stalled after taking off from Tokyo. An inspection revealed a hole in the turbine casing.

 

• Sept 18, 2006: The right engine of another Malaysian 777 shut down 40 miles north-west of Brisbane but was restarted.

 

Theories to explain Flight 038's landing 1,000ft short of the Heathrow runway, included computer failure, bird strike and contaminated fuel or fuel starvation.

 

But last night bird strike and fuel starvation appeared to have been ruled out as no feathers were found nearby and had there been fuel problems the engine would have spluttered.

 

A Boeing spokesman said: "The 777 has been in service for 12 years and has flown around 3.6 million flight hours during which there have been no fatalities. It would be inappropriate to comment at this stage."

Heathrow crash inquiry focuses on fuel supply

 

By David Millward, Transport Editor

Last Updated: 2:11am GMT 28/01/2008

 

Investigators trying to pinpoint the cause of last week's crash landing by a British Airways jet at Heathrow have switched their focus to the aircraft's fuel.

 

It is understood the inquiries will try to establish whether other aircraft which refuelled at Beijing have run into trouble. This would establish whether there was contamination at source.

 

If the fuel was not contaminated, the focus will switch to what happened to the fuel between the tanks and the engines. The Air Accidents Investigation Branch said it would examine the "complete fuel flow path" from the aircraft tank to the engine fuel nozzles.

 

A clearer picture is beginning to emerge of the circumstances surrounding the drama in which a Boeing 777 carrying 136 passengers, made a forced landing short of the runway at Heathrow last Thursday.

 

Initially it was thought that both engines had failed. This view was reinforced by a newspaper interview in which John Coward, the senior first officer who landed the plane, spoke of total power loss.

 

But in its report, the AAIB said the two engines on the 777 did not shut down, as first thought.

 

It said that the thrust on the right engine fell - which could explain why the plane appeared to bank as it approached Heathrow. Then eight seconds later, the thrust on the left engine also fell. However, both engines continued to work, but with inadequate power.

 

Investigators have also established that the engine control commands worked normally and the aircraft was found to have an adequate fuel supply when it was examined on the ground.

 

The mystery now is why the engines failed to respond despite the automatic throttle appearing to work normally.

 

The consensus among pilots is that the plane's difficulties could hinge on the failure of fuel to reach the engine.

 

American safety investigators have logged six incidents on 777s, two of which relate to fuel problems.

 

Oil pump contamination was identified as the reason for an Air France 777 suffering an "uncommanded engine shutdown" on July 1 1998, which caused the plane to be diverted to Tenerife while en route from Sao Paolo to Paris.

 

On June 6 2001 a Thai Airways 777 suffered a ruptured fuel tube on a flight from Taipei to Bangkok.

 

However the recording of a number of incidents by the AAIB's American counterparts reflects the strict safety rules in the aviation industry, which demands even the smallest glitch is reported.

 

Regulators on both sides of the Atlantic have found no reason to issue any directives to the industry, let alone demand the grounding of the entire 777 fleet.

 

Rolls-Royce, the manufacturer of the engines on the stricken 777 also declined to discuss the significance of the latest findings or what action it was taking as a result.

 

A spokesman said the company was co-operating with the investigation.

2 of it is from MH.Not including the one in Sweden...

[LeeCH 0]

SQ has its shares of engine failures as well on the 777 fleet. One incident from ADL-SIN diverted to PER. Second incident from PEK-SIN. And the most recent, a B77W in ICN.

[Pieter C. 5]

Can anyone be more specific about the engine types (PW, RR, GE) ?

[Peter Smith 1]

MAS also had one in September 2001 out of Perth. All MAS's problems have later led back to the manufacturer of that particular product, so no one go judging MAS! The ADIRU failure out of here in 05 is being used as the basis of the "Speedbird 38" incident as both had uncommanded loss of thrust.

 

And the Sweden incident, it has happened numerous times. CX out of BKK, SQ (9V-SRA) out of PER to name but a few! The honeycomb is made by Snecma not RR, so RR are passing the buck.

 

Air France (GE engines) recently had their ETOPS cert withdrawn on the 777 (interesting move as 777 is certified 180-mins from the time she first leaves BFI regardless of operator), due to their troubles and number of inflight shutdowns. One was on a CDG-PEK flight, that diverted to Irkutsk. Due to it being in the middle of siberia and therefore the wx being -40 6months of the year, the 772 was stranded for 3months!

[BC Tam 2]

There was another MH 772 RR engine related incident outbound from BKI years ago. Was widely reported here in MW too at that time

 

And then there is the most recent incident in Oct last year

[S V Choong 4]

Can anyone be more specific about the engine types (PW, RR, GE) ?

 

• Air France 772ER (GE) & 77W (GE)

 

• Emirates 772ER (RR), 773 (RR), 77L (GE) & 77W (GE)

 

• Thai Airways 772 (RR) & 773 (RR)

 

• Japan airlines 772ER (GE) 773 (GE), 77W (GE)

 

• Malaysian 772ER (RR)

 

• British Airways 772ER (mix of GE and RR). Aircraft involved in incident is an RR engined a/c.

 

 

Seems like the RR and GE engines are the dodgy ones.

General Electric probes power loss on 3 recent 777 flights

By Stephen Trimble

 

An unusual rash of engine shutdowns since early December has temporarily stranded three of the normally reliable General Electric-powered Boeing 777-300ERs.

 

Although each incident involved a shutdown of the GE90-115B, GE’s investigation so far indicates the causes of each power loss appears to come from three different sources, says a company spokeswoman.

 

The incidents have forced two different Air France airliners to make emergency landings at alternate airports since 12 December. Similarly, on 1 February, a Singapore Airlines 777-300ER was forced to land at Frankfurt International Airport in Germany.

 

In the first incident, the Air France pilot crew noticed “excess vibrations” and powered down the engine, making an emergency landing in Rome. A visual inspection revealed excessive wear on a stage six low pressure turbine blade that “reduced contact pressure between blades on that disk,” the spokeswoman says.

 

On 25 January, a second Air France 777 diverted to Milan Malpensa airport after an inflight engine shutdown. The engine’s transfer gearbox broke out of its housing, causing the power loss.

 

Finally, the Singapore Airlines flight was disrupted by an undisclosed problem with the engine’s accessories gearbox. At press time, GE was not certain if the pilot commanded the engine to power-down, or if the engine failed in flight. GE is continuing to investigate the incident to uncover the root cause of the gearbox issue.

 

Both the transfer gearbox and the accessories gearbox are produced by the same supplier, Italy’s Avio. GE is “working with them to find out what the cause would be,” the spokesman says.

 

Both components have been installed on older-model aircraft equipped with GE90-94B engines, achieving an 11-year in-service record with no prior incidents before 25 January.

 

Air France was the launch customer for the GE90-115B-powered 777-300ERs, and therefore has the fleet’s oldest airframes and engines in service.

Guess MH is a bid unlucky since it involves 2 of the MH birds here.

Though I am not familiar with the incidents, I guess its lucky for Boeing service record instead since we have good pilot controls to overcome these problems mid-air. Isk..

BA has one engine fire over Houston back in 2004 and I was in Houston that time. The 777 route was IAH-LHR. The plane was only 20 minutes into the flight and force to return to IAH. I went to the airport the next day and saw the aircraft is sitting at the Garret Hangar at Rankin Rd, with the left engine open and some smoke mark under the left wing.

 

Continental also has one 777 with engine failure back in 2005. The plane was from Tokyo NRT to Houston IAH. The 777 make a diversion into Anchorage. One good thing about that diversion is that all passenger were given an overnight Alaska travel voucher while awaiting another 777 to be ferried from IAH.

 

both incident involving GE-90 engines.

British Airways (London) is officially declaring G-YMMM (msn 30314), the Boeing 777-200ER that was severely damaged in an accident at London Heathrow on January 17, 2008, a write-off. While landing, the aircraft’s nose-gear collapsed, the right main landing gear separated from the wing – rupturing the rear right wall of the centre fuel tank – and the left main landing-gear was pushed up through the wing root. Both front wheels of the right main landing-gear broke away and penetrated the right rear fuselage at seat height, and the gear also damaged the wing-to-body fairing and penetrated the rear cargo hold. The damage was described as “beyond economic repair” by the UK Air Accidents Investigation Branch.

 

Photo: G-YMMM is only the second Boeing 777 to be written off, following a General Electric GE90-powered 777-200 which was disassembled for parts in 2006.

This is purely academic, but would it be technically possible to restore the bird to flying condition even if someone was willing to bear the cost ? And how safe would it be thereafter, bearing in mind the out of norm stresses the structure must have endured at point of impact ?

Of course its technically possible. Change almost everything save the recoverable items like displays, some seats etc. But with possibly 80% - 90% component and parts changed, would it still be the same aircraft restored? The key word is 'beyond economic repair'

I think the same term was used on MH's 9M-MKB that was written-off. The cost of repairs + useable existing parts of aircraft exceed the present depreciated or mkt value of aircraft. Better to just get another one from the marketplace.

British Airways Crash Likely Caused By Ice In Fuel

 

September 4, 2008

A British Airways plane crash at London's Heathrow Airport in January was likely caused by ice in the plane's fuel system, a report into the incident said on Thursday.

 

The accident, which seriously injured one passenger when the plane landed 1,000 feet short of its intended runway, was not the fault of the flight crew, the Air Accidents Investigation Branch (AAIB) said in an interim report into the incident.

 

It also ruled out problems with the amount or quality of the fuel, focusing instead on the build up of ice in the system. The Boeing 777 aircraft, which used engines from Rolls Royce, had flown into London's Heathrow from Beijing.

 

"There are no safety recommendations specific to British Airways. We will work closely with the relevant regulatory authorities and comply with any requirements issued to all operators (of the aircraft)," the British carrier said in a statement.

 

The AAIB report said the incident was unique and the investigation would continue.

 

"Extensive data analysis has revealed that not only has there never been a previous occurrence of this type on the Boeing 777, but also that this is the first known occurrence of this nature in any large modern transport aircraft," it said.

EU, US To Issue New Boeing 777 Safety Rules

 

September 4, 2008

US and European air-safety regulators, concerned by potentially dangerous ice build-ups in the fuel systems of some long-haul jets, will issue new operating rules for about 220 Boeing 777 planes, people familiar with the matter told the Wall Street Journal.

 

The mandatory safety directives apply only to planes with engines manufactured by Rolls-Royce, which comprise about a third of the Boeing 777 fleet world-wide.

 

But under prodding from British officials, Boeing will analyze whether similar precautionary measures should be extended to the rest of its 777 line, people familiar with the matter told the WSJ.

 

The rules are expected to be released in the next few days.
