Caveats

Not everyone here is a professional pilot, myself for example, but the analysis of the flaperon is not an area where professional pilot expertise is going to help. It's the realm of engineers, metallurgists, physicists, etc. I'm not one of them either. As I noted, at a minimum those are great photos of the flaperon. The author is working within the limits of what he has access to. It's better than nothing, which is what we have otherwise. Hopefully we will soon get a definitive analysis from people who have full access to the flaperon, but I'm not holding my breath.

Bear in mind that the efforts made by the authors of such papers do so in an attempt to bring some semblance of reality to the vacuum left by those who do have lawful access to all the data, but feel bound or obliged to "sit" on it.

Well said indie cent.

What a complete waste of time and effort by someone.

Some are. But a few are those peddling books or pitching articles to magazines; talking heads who want to appear on TV; quasi-experts who are touting their businesses; pundits pushing their pet-conspiracy-theories, etc.

Published for a single reason - the collective photography and, in particular, the shot of the flaperon with the outline of the full unit added in.

If nothing else the amount of the trailing edge gone compared to the rest of the unit might make those who believe it was a period in the surf grinding against the rocks think twice.

Tom's flaperon paper was distributed to the IG (18 people now) before it was posted here. I think it has some thoughtful analysis. Determining if the flaperon separated in the air (due to a high speed descent) is very important to the search area definition, so I welcome his contributions.

Sums up a discussion forum like this quite well

No use complaining for that is what drives the reader traffic on the internet.

as always you have to read carefully for the credibility of the content and not just take it as gospel.

Quote from M.Mouse:
"What a complete waste of time and effort by someone."

On the contrary, in comparison with the efforts of the vast majority of us posters on this forum, that is a remarkably well-researched and impartial paper; written and presented to an unusually high standard. I'm in agreement with mm43 and PPRT.

Considering the amount of painstaking work it represents, the expense of the investigating authorities publishing a statement correcting any misconceptions it may contain would be justified and timely, IMHO.

Chris: ATSB has Tom's analysis and they are looking at the implications.

Come now, the paper itself notes: "The team of Boeing engineers, technicians, and managers would be able to determine ‘likely’ (say 80% confidence level) failure mode within hours of physically observing the MH370 Flaperon in France."

The ATSB, Boeing, BEA, NTSB & Malaysian investigators involved aren't idiots.

Folks,
Re. NTSB, BEA I would agree, but ATSB and Malaysians, I would not be quite so certain -- based on local experience.
Tootle pip!!

Anything latest on this? Is under water search still going on in Indian Ocean right now? There are many like me eagerly to know anything related with this issue.
Adding another post here which I have just found.
======
12 October
A woman in the Philippines claims to have found the wreckage of a plane "containing many skeletons and painted with the Malaysian flag", prompting speculation it could be part of missing Malaysia Airlines flight MH370.
Siti Kayam claims to have stumbled across a smashed fuselage while she and others were out hunting for birds on the island of Sugbai.
According to the Daily Mail, police in neighbouring Borneo have confirmed they received a report of the discovery in thick jungle on the remote island.
Authorities are reluctant to say more at this time and "remain reserved about the report", says the Mail.
Sugbai lies more than 4,500 miles east of Reunion Island, where French officials believe part of the missing Malaysia Airlines plane was found earlier this year.
Experts say it is "highly unlikely" that debris could have drifted from the remote Philippines island to the other side of the Indian ocean, especially as Borneo, mainland Malaysia and parts of Indonesia lie in the way.
It is understood the report will be verified or dismissed after further investigation within the next day or so.
MH370 disappeared in March last year with 239 people on board. A senior French prosecutor confirmed last month that a series of numbers found inside the barnacle-crusted jet wing part, found on Reunion, matches records held by a Spanish manufacturer as being part of the Boeing 777.

@theAP

That claim was ruled out as a hoax:

KOTA KINABALU: Sabah police have confirmed that claims that wreckage of Malaysian Airlines flight MH370 was sighted on an isolated Philippines island are fake.

State police commissioner Datuk Jalaluddin Abdul Rahman said they have conducted necessary investigations and found that the information is false.

Trans-Atlantic debris from Cape Canaveral missile launch

Some of you outside the UK may not receive the news that a large, barnacle-clad object has been recovered by coastguards off the Scilly Isles (off the SW extremity of England). A news report from this morning subscribes to the initial theory that it is an inter-stage section from a failed Falcon 9 rocket launch at Cape Canaveral in June this year.

This evening, however, that has been challenged on the basis that - on closer examination of its paint scheme - it is from another Falcon 9 that was successfully launched in September 2014. In that case the object would have fallen into the sea from a much higher altitude 14 months ago, and then carried on the Gulfstream (North Atlantic Drift) to Blighty.

That picture (Exhibit 21) is not particularly accurate. Exhibit 1 shows that the rear spar is at approximately 60% of the flaperon chord, so about 40% of the bottom area is missing.

MH370 search narrowed to 'hot-spot' as analysis finds plane did not conduct controlled landing - Telegraph

Australia has released new analysis of the missing MH370 flight, identifying a top-priority search in the southern Indian Ocean and indicating the Boeing 777 did not conduct a controlled landing

beamender99: The statement in the ATSB report about controlled ditching reads as follows:

Ditching considerations
A controlled ditching scenario requires engine thrust to be available to properly control the
direction and vertical speed at touchdown and to provide hydraulic power for the flight controls
including the flaps.
The final SATCOM transmission was considered by the satellite working group to be due to a
power interruption to the SDU. Given the performance analysis by Boeing, it is entirely reasonable
to assume that engine flame-outs triggered the APU auto-start that restored power to the SDU.
This evidence is therefore inconsistent with a controlled ditching scenario.
That is mostly rubbish. Engine thrust is not required to properly control the direction and vertical speed at touchdown and to provide hydraulic power for the flight controls. In the case of MH370 the Ram Air Turbine provided the electrical and hydraulic power required to operate the flight controls. It did not allow extension of the flaps. Without flaps the landing speed will be higher, but the airplane can land without flaps. To understand that engine thrust is not required for control of airspeed and vertical speed at touchdown, have a look at these time histories from the A320 ditching in the Hudson river:

Bit of a difference between a controlled ditching in a river and... the Southern Indian Ocean, a thousand miles from land, with waves several metres tall.

I can't see any sane reason why someone who planned a controlled ditching there would have waited for the engines to run out of fuel first. That would dramatically reduce their chances of success.

MG23:

No one actually knows the seastate at the time and place flight MH370 ended. I didn't imply that a controlled ditching was easy or likely to be successful. There is also nothing to suggest that a ditching (or anything else, for that matter) was 'planned'.

But there is no justification for stating in an official report that "This evidence is therefore inconsistent with a controlled ditching scenario".
