The following was published in the newsletter of the Australian Licensed Aircraft Engineers Association. While primarily crticising Quantas, it reveals that SIA had invested heavily in the Rolls Royce engines.

Prior to the incident, there were already safety concerns about design flaws in the engine.

SIA however chose to "act blur" and keep on flying.

Even after the incident had occured, SIA chose to continue to "act blur" to try and downplay the problems. SIA even went to the extent of doing an "wayang" inspection that was physically impossible in the stated time frame (notice how similar this is to the initial reactions to the floods in Singapore !).

It was only when the problem became to obvious that they finally grounded the SIA planes.


QANTAS, SingaporeChalk and Swiss Cheese

After the infamous QF32 Trent 900 A380 incident on 4 November 2010, the ALAEA has been attacked by Qantas management for making well-educated and knowledgeable comments in the media. Qantas spin doctors have attempted to portray the ALAEAs concerns in regard to Qantas brand as an industrial campaign.

Qantas management, and in particular Alan Joyce and the Qantas board, miss the point. The ALAEAs actions are founded on a genuine concern for the sanctity of the famous Qantas brand, its impressive long-term aircraft safety record being its only distinguishable and marketable advantage. That record, and the Qantas brand, was created and protected by strict quality control and the skill and diligence of Australian aircraft engineers performing the major overhaul and repair on Qantas aircraft (including engines) in Australia under the Australian regulatory regime. The only thing that distinguishes Qantas in a very competitive market, where Qantas suffers the disadvantage of remote location from major world markets and unfair competition from subsidised airlines, is its safety record. Australian aircraft engineers have been the protectors of this record.

The ALAEA’s actions over a number of years have been aimed at correcting the current Qantas board and management direction of cost-cutting without considering the serious threats to its main product, a container that gets people through the air from one place to another, safely. Qantas managements own actions degrade the brand by handing over the control of its product to companies overseas. Ill-considered, short-term cost-cutting and a lack of investment in Australian-based engineering will have detrimental medium to long-term effects on Qantas, its employees and the Australian aerospace industry skills base.

Qantas approach after the recent incidents involving Rolls Royce aircraft engines has to be applauded. It drew the line on the world aviation chalk board in black and white when on 4 November Qantas Chief Executive Alan Joyce told reporters in Sydney, we will suspend all A380 takeoffs until we are fully confident we have sufficient information about (flight) QF32.

It was reported that Joyce said the plane was capable of flying on two engines. This was a significant engine failure. We are not underestimating the significance of this issue. Grounding the A380 fleet is a significant issue for us, he said. Effectively what this meant was that the Qantas A380 fleet would be grounded until they could inspect all engines and be sure they were safe to fly. Qantas have 6 A380s and 24 engines to inspect. Joyce firmly placed safety before schedule and safety before revenue. The Qantas fleet remains grounded after Qantas engineers, conducting thorough and detailed inspections, found oil in areas of other engines where it shouldnt be.

By contrast on 4 November after the Qantas incident, Singapore Airlines grounded its entire fleet of 11 A380s and 44 Rolls Royce RB211 Trent 900 engines for a short space of time and had them back in the air after about 24 hours, declaring that after checks they were fine. It seems logistically impossible to carry out detailed inspections on 44 engines to ensure their safety within such a short period of time but Singapore Airlines was prepared to risk it. Then on 10 November, Singapore Airlines could not further ignore the problem after Qantas engineers found oil problems in some of its other Rolls Royce engines on A380s, and Singaporeconducted further inspections on its engines and found similar problems. It had to take action and did so by grounding 3 of its A380s but left the other 8 flying. StillSingapore is taking a calculated risk for revenue versus safety.

These events and the different approaches demonstrated in the current circumstances by the two airlines illustrate the massive difference in safety and risk management philosophy of these two airlines. They are like chalk and cheese. Qantas shows a cautious absolute safety approach and Singapore just how prepared it is to take a risky approach.

The cheese relevant to this situation is well known in the aviation industry as the James Reason Swiss cheese model. This is based on the hypothesis that a series of seemingly unrelated safety events, occurring like holes in Swiss cheese, one day line up to cause a major, catastrophic event. Safety and risk management practice should therefore be designed to address the minor events so a catastrophic one doesnt happen. Definitive action to apprehend a sequence of events prevents a major disaster. In the current situation, Qantas decided to take definitive action to arrest the sequence of events whilst Singapore appears to be waiting for the holes to line up.

But whilst there may be events that appear unrelated, it is worth asking whether there are any common factors, actions or changes that have been taken that could directly or indirectly be causing the events?

Prior to July 2009, since the introduction of the B747-400, Qantas maintained and overhauled all its RB211 engines for B747 jumbo jets in its Rolls Royce centre of excellence Sydney engine line facility. Qantas established world records for reliability in longest engine hours on wing for its Rolls Royce engines, fuel efficiency and Rolls Royce used Qantas experience to improve its RB211 engines. The engine that had problems on 5 November on the B747 out of Singapore had been in service at Qantas since 1992 after being bought from British Airways. Qantas had maintained it, in-house, for approximately 18 years up until June 2009 without any major events. In the early part of 2009 Qantas commenced the implementation of a shutdown of its Rolls Royce engine overhaul facility after making a cost-cutting decision to outsource its RB211 – including Trent 900 – overhaul work to HAESL in Hong Kong. 360 Australian engineering jobs were lost. This cost cutting approach sacrificed some of Qantas control over its own product in that it handed over the safety and security of its engines to a competitor, Singapore Airlines.

Interestingly this was a complete turn-about from Qantas corporate philosophy and principles of the late 1980s and early 1990s, which led them to make the decision to have the Rolls Royce engine centre in the first place. One of the major factors influencing the decision to do the work in-house was the issue of tracking parts and those parts hours of usage. This is a critical factor in determining when particular parts should be serviced, repaired or replaced. The other option for Qantas was to have the work done in Singapore by Singapore Airlines engineering company and a subsidiary. This, however, would have involved a system of pooling parts where there was no guarantee your part i.e. a Qantas part tracked for hours of usage in the Qantas system, would come back on the engine, and no guarantee the records of usage for the parts used on your engine were in fact correct. In effect, Qantas identified too many holes in the cheese and would not take the risk. It decided the best way to control the quality of its engines and the safety of its product and aircraft was to do the work in-house under Qantas strict regime of quality assurance. Qantas wanted to retain control over its product and the brand of the airline – its international safety record.

So whats changed for Qantas after having the worlds best practice in engineering for Rolls Royce RB211 engines? Fundamentally Qantas has taken the risk to sacrifice its control over the safety of its product for a perceived cost reduction by handing over its RB211 and Trent engine work to Hong Kong and Singapore. Thus, they have created their own Swiss cheese hole by taking the risk they purposely avoided in the late 80s and early 1990s.

In July 2009, Qantas handed over its RB211 work including the RB211 Trent 900 to HAESL and SAESL. HAESL is Hong Kong Aero Engine Services Ltd, a joint venture of SIA Engineering Company (10%), Hong Kong Aero Engine Company (HAECO) (45%) and Rolls Royce (45%). Their principal activity is engine repair and overhaul of Rolls Royce Trent and RB211 series engines. SIA Engineering Company (SIAEC) is a wholly owned subsidiary of Singapore Airlines.

Another Rolls Royce and Singapore Airlines joint venture is International Engine Component Overhaul Pte Ltd (IECO). It is made up of SIA Engineering Company (50%) and Rolls Royce (50%). Their principal activity is specialising in the repair and overhaul of Rolls Royce Trent & RB211 Nozzle Guide Vanes and Compressor Stators. IECO currently has a worldwide customer base that encompasses the Asia Pacific region, such as Singapore, Hong Kong, Australia, China, and the rest of the world, which includes the United Kingdom, USA and Europe. It is a Rolls Royce certified Gold Centre of Excellence for the repair of Rolls Royce aero engine components.

In addition SIAEC, HAESL and Rolls Royce have another joint venture based in Singapore, Singapore Aero Engine Services Pte Ltd (SAESL). This is made up of SIA Engineering Company (50%), Rolls Royce (30%) and Hong Kong Aero Engine Services Ltd (HAESL) (20%). Their principal activity is as a Rolls Royce Centre of Excellence in the Asia-Pacific for the repair and overhaul of Rolls Royce Trent engines. SAESL began operations in 2001 and has grown their capability to support the full series of Trent family engines globally within a few years. Rolls Royce has SAESL as the first Trent 900 Centre of Excellence and SAESL are supporting Singapore Airlines fleet of A380s.

Just prior to the full handover of its RB211 and Trent work in 2009, Qantas had been getting parts of the complete engine in module form, from a contractor overseas. This might include getting a turbine module and fitting the completed module to Qantas engines. Before this, however, the Qantas/Rolls Royce centre did the complete rebuild of all modules and had never had a major failure. Sources within Qantas say that the engine with problems flying out of San Francisco in August and out of Singapore on 5 November, had been one of the last engines assembled out of the Qantas/Rolls Royce facility in Sydney but also had an overseas reconditioned turbine module fitted. This, however, is yet to be confirmed.

On 13 August 2010, the USA FAA issued an airworthiness directive for Rolls Royce RB211 Trent 900 engines, those engines used by Qantas, Singapore Airlines and Lufthansa on their Airbus A380 aircraft. In part the directive said, rearward movement of the IP turbine would enable contact with static turbine components and would result in loss of engine performance with potential for in-flight shut down, oil migration and oil fire below the LP turbine discs prior to sufficient indication resulting in loss of LP turbine disc integrity.

On 30 August 2010, a Qantas B747 jumbo powered by Rolls Royce RB211 engine with a Trent variation had an uncontained failure with one of its engines shortly after it left San Francisco and had to turn back.

On 4 November 2010, a Qantas A380 powered by Rolls Royce RB211 Trent 900 engines had a massive uncontained engine failure after take-off from Singapore and returned safely to Singapore.

On 5 November 2010, a Qantas Boeing 747-400 made an emergency landing after leaving Singapore due to another Rolls Royce RB211 engine failure. Passengers on board the flight said they heard a bang and saw smoke coming from the aircraft’s engine minutes after takeoff.

These events are serious, life threatening events. So why would Singapore Airlines keep flying its A380 Trent 900 engined aircraft and risk it? The answer probably lies in what is really at stake for them and Rolls Royce. They have to be seen to be backing their own work and product, out of their engine joint ventures or risk losing credibility and their massive capital investment in the ventures. Depending on what unfolds in the QF32 investigation it may well be that SIAEC and Rolls Royce have to foot the Qantas compensation bill together.

One thing needs to be kept firmly in mind. Rolls Royce, the maker of the Trent 900 engine which disintegrated, knew about the faults that the current airworthiness directive on these engines says are likely to have caused an intense oil fire in a structural cavity in the intermediate pressure turbine area of the engine. But Qantas was cut out of the information loop.

On 18 November 2010, the Sydney Morning Herald reported that, Rolls Royce had made changes to the design and manufacture of new A380 engines to stop oil leaks, but it had not done so to the engines on the Qantas A380 fleet.

If this was significant, and was known to be significant, we would have liked to have known about that, Mr Joyce said.

It doesn’t look like it is a significant modification, but it is a modification that has an impact on how the engines are performing and it is a modification that indicates whether you are going to have a problem or not with the engine.

Rolls Royce was responsible for all maintenance on the A380 engines, Mr Joyce said. He said the modification made by Rolls Royce to the engines on the production line appeared to be an indicator of potential problems.

This acknowledgement by Alan Joyce, Qantas CEO identifies a direct ramification of outsourcing, particularly overseas, and is a major problem. Once you outsource offshore you not only lose control over your product, but control over the flow of relevant information affecting your product and, in Qantas case, you jeopardise the sanctity of the brand. This is something that Qantas and its shareholders cannot afford. If your brand is based on having the worlds best practice, which Qantas had, then outsourcing things such as engine and aircraft overhaul and repair then you lose control over the management of your brand.

Prior to 5 November 2010, as outlined in a report attributed to Airbus Technical Services:

Rolls Royce had designed and was introducing a fix for the oil leak issues for this into the engines at its own speed. Qantas was left in the dark. It is fair to suggest that Qantas needs to review relationships with engine manufacturers in which it pays for power by-the-hour and leaves much of the maintenance and oversight of those engines to the designer and manufacturer.

To emphasise the obvious, the questions concerning the timeliness of the Rolls Royce responses to a known problem, and its capacity and willingness to share them with the airlines concerned will not go away. If the engine maker doesn’t address them its customers will.
The interests of the engine maker and holder of the service agreements are not the same as those of the airline. A carrier might want to correct and replace inadequate design features to a different, more urgent timetable than the party that benefits from the support contract, and has its own brand image to protect.

Whilst Alan Joyce has distinguished Qantas from Singapore by grounding the Qantas A380 fleet he still faces the same engineering quality problem of having no real control over the quality of the engines used on its A380s and some B747s. In fact Singapore Airlines (through its engineering subsidiary SIAEC, SAESL, HAESL and IECO) and its higher risk philosophy has more control over the Qantas brand than Qantas itself. Joyce and the Qantas Board continue to put the Qantas brand at risk, and this is no longer just a possibility it is definite.

What the shareholders don’t know is that a relatively small investment of about $50 million or less would have kept the Qantas Rolls Royce engines facility in Australia under their and Qantas control.

The Qantas Board should be intelligent enough to recognise that putting the Qantas brand in the hands of overseas engineering is an unacceptable risk, both from commercial and a passenger safety considerations.

The Qantas Board needs to commit to and spend the capital (approximately $100 million) to have its A380 and new B787 fleets overhaul and maintenance done in Australia. Its a cheap price to pay to protect the only market advantage Qantas has, its brand and safety record.

Things are just NOT going well with PAP!
 
Didn't Quantas resume flying those same A380s with the same engine? Doesn't that makes the grounding of all its A380 - absolutely pointless? IIRC The modification to the engines and the change of engine to the planes only took place some time after the after they started flying again. ALAEA(Australian Licenced Aircraft Engineers Association just in case no one knows what it means) is of coz taking the opportunity to condemn Quantas as they are trying to fight to get the maintanence back to Melbourne which is why the article sounds very bias.

In which case general maintenance is now done by Malaysia Airlines Engineering and Maintenance and not ST Engineering although I can't be sure if the Rolls Royce engines(can someone confirm this) are service here since I can't seem to find any article on it

Does the decision by Singapore Airlines and Lufthansa to continue A380s services after those inspections make them less safe than Qantas.

No, all it means is that they have not discovered the same problems that are of such clear concern to Qantas. The grounding decision by Qantas was unavoidable, given the seriousness of the events that occurred in the QF 32 incident, and has been received with admiration in the airline industry.

Qantas simply cannot risk a similar incident on another A380. Singapore Airlines and Lufthansa have not had such an incident, but since QF 32 occurred they, like Qantas, have been given very demanding inspection requirements for their Rolls-Royce engines, and if they turn out “clean” they fly.

Could it be that Qantas did something “wrong” with its A380 engines?

Maybe. But there is no evidence to support that being the case. It had complied with earlier airworthiness directives requiring other inspections of these engines. The “clustering” of the Rolls-Royce Trent 900 issues on the Qantas fleet defies explanation at this stage, but raises the possibility that defective materials in its engines have in failing, revealed a vulnerability or defect in the engine design.

If, stress “if”, this is found to be the case, Rolls-Royce and its customers are going to have to modify or replace their engines.

Passing current engines as fit for flight is one thing, but finding and fixing the underlying cause or causes of the faults Qantas has uncovered is a long-term and critical safety matter.

SIA needs to be brought down to earth by not paying it's pilots and staff properly .
 
It is ALAEA's fight for survival because they are not competitive and insufficient engines in their fleet to support their own maintenance facility. It is of course a matter of pride to ALAEA, but ASTA too could not survive as facilities such as those from China, Hong Kong and Singapore are more competitive. Such a facility need customers and who would want to fly their aircraft to Australia for maintenance as Australia is not situated along major flight routes.

If Qantas can have another company do it cheaper, why cut their noses to spite their face? In the past when the AUS$ was about par with SIN$, they were already not competitive, what about today? Whatever opinions expressed by SLAEA, are theirs, but I doubt many people will agree with them.

While ALAEA might have an agenda, there are two key facts in the article which are not in dispute.

1) The US FAA had issued a directive with regard to issues with the engines.

2) Shortly after the directive was issued, there was not 1 but 3 incidents involving the engines.

If this is still not sufficient to raise a red flag, what is?

Or does the airline industry operate along the line that as long no one died, things are OK and they can keep on flying?

I did a quick search and base on the dates I think it's referring to this

http://www.airweb.faa.gov/Regulatory_and_Guidance_Library%5CrgAD.nsf/0/BD36C747996B02D78625777E00523051?OpenDocument

1)Apparently, Rolls Royce is aware of the problem since January. So the question such be were they doing the changes. If Lufthansa and SIA were flying during that period, were the recommended changes already made to those planes? If so, why aren't the changes made for Quantas planes

2)See point 1. The issue is not new, Rolls Royce was aware of it since January. All incident you referred to involves Quantas planes for some reason. I suspect the maintenance crew servicing Quantas planes at more at fault here then the actual existing fault of the engine

Rolls-Royce plc has issued RB211 Trent 900 Series Propulsion Systems Alert NMSB RB.211-72-AG329, Revision 1, dated January 13, 2010. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

Also since 2008, Quantas have had incidence involving their planes almost on a monthly basis, the same year when the maintenance was outsourced. I suspect it has as much to do with their outsource maintenance crew as it is the engine fault. It's hard to explain otherwise why SQ which have twice as many planes with the same engine and twice as many flights have not suffer the same incidence while Quantas ran into 3 of them within a short span of time

OK found what I was looking for
http://www.saesl.com.sg/client.html

So now the juicy part is, did SAESL provide only proper servicing for SIA and gave 3rd rate service to Quantas(refer to earlier post if U have no idea what I am talking about)
 
It is call a lan lan situation. You must understand the aviation industry to know why.

Each company engine has very different specifications from engine design to the simplest mounting screws and place on the aircraft. This makes the switching of one company's engine to another practically impossible.

The obvious answer? Of course all flights will carry on as usual, since stopping all flights and removing all the engines in one go is not possible. Once an AD is issued, compliance of the AD will be carried out as soon as possible, and by this, it means when the engine has reached it's flight cycles and due for overhaul. In the process, the engine will then be rectified to comply with all AD's issued since it's last visit to the engine overhaul centre.

This is the normal practice in the airline industry as AD's being issued may be many, some important others not so. As long as there is no directive requesting airlines to stop operating the aircraft, it is up to the airlines themselves to schedule the grounding of their aircraft.

Red flag or no red flag, these engines have been operating for a few years. The likelihood of a repeat of the 4th Nov incident is pretty unlikely, notwithstanding the one on 5th Nov as they are totally unrelated. Different aircraft and different engine involved. As earlier stated, it is not possible to immediately cancel all flights and screw up thousands of passengers' travel plans by grounding all A380 aircraft.
 
Dear Arun

The FAA directive indicates a problem. However that problem might not at that point lead to a failure as happened in the Quantas engine. The information from Flight global/ Flight international seems to indicate that the problem lies with an oil pipe or oil lubrication point incorrectly designed and or fitted which lead to an oil leak and hence the fire. This might have something or not to do with the issues raised in the FAA directive, we lack clear cut definitive information at this stage.


1. Rolls Royce designs not only the engines but determines the maintaence protocol, steps procedures, for testing and repairing the parts on the Trent 900, not those jokers in Australia. If there is a design issue of some form the correct people to mod the engine are not the Aussies but Rolls Royce and National Authorities. If in fact it was a design flaw then whether the trent 900 was maintaned in sydney or the moon becomes irrelevant. Certification for new engines and mods to new engines takes years to come into fruition, just take a look at CFM for example or how long it took for Rolls Royce to get new heat exchangers installed to prevent the extreme ice issue with fuel supply.

2. The RB 211 has nothing to do with the Trent 900, they are at leats twenty years part. FAA calls the trent 900 the RB 211 Trent 900 but for all intends and purposes they are differing engines. The RB 211 engine which blew if it was the mod version has a trent 700 HP system involved which is very different from the one in the Trent 900.

3. Lufthansa and Quantas and SQ are still merrily flying the unmod engines. Do u think spare parts and mod spare parts grow on trees like apples and appear overnite ?




Thanks
