MH 370 final report
 
Nothing new in final MH370 report released this morning. Plane was sound, pilots in good health mentally and physically. Investigators not able to find out why transponder turned off or why plane diverted from filed flight plan under human control, not autopilot. They can't rule out interference on flight by third party. Remains one of world's aviation mysteries. Thoughts are with families of passengers and crew

Mh370 final report
 
MH370 final report out.

So what’s new in this report? To start with, the report says the turn back after IGARI had to be manually flown, the rate of turn was too high for any automatic mode.

This must mean the pilots were faced with massive electrical failures sufficient to knock out the autopilot. The aircraft was then seen on primary radar to meander and not maintain any fixed level(phugoid?).

With communication/electrical failures, followed shortly after by pilot incapacitation, we are surely looking at a decompression caused by the rupture of the crew oxygen cylinder in the avionics bay under the flightdeck. No other scenario fits so neatly. There are not many failures that will allow passive flight to fuel exhaustion. The pilots have finally been cleared of any nefarious acts.

Without hard evidence the officials will not speculate about any cause, they only report known facts. As the final crash site is unlikely to be found, it’s going to be down to us, ppruners to fill in the gaps.

"This must mean the pilots were faced with massive electrical failures sufficient to knock out the autopilot."
No... that's not what it "must" mean.

"The aircraft was then seen on primary radar to meander and not maintain any fixed level(phugoid?)"
If you read the report you would have noted that those vertical variances were discounted. If you know anything about (those types of) military primary survellance radars, or do some reading about them, you'll understand why the derived altitudes should be discounted.

My Lord...

"No other scenario fits so neatly"
My Lord (again)...

"The pilots have finally been cleared" etc
I can't even bring myself to say "My Lord" again

"it’s going to be down to us, ppruners to fill in the gaps"
Ahhh! Now I see! Of course -- the solution lies with those who frequent pprune! (especally those who frequent "Rumours and News"!) The silly Malaysians and Aussies and Brits and French and Americans and Chinese, etc. etc. could have saved a lot of time, effort and money.
My Lord...

Was there any impact analysis done on the right flaperon recovered for witness marks to determined if this was a controlled ditching?
I can't see that in the report.

Yes, in section 2.6.3 -- and in the Appendices (series of 1.12) as well.

Well said Grizzled. Well said indeed.

WOW! How can you even BEGIN to connect the dots here?!?

If there were "massive electrical failures sufficient to knock out the autopilot", then how on (or over) earth could the airplane settle into stable and "passive flight to fuel exhaustion"?!?

Neatly?!? I'll say it again... "My Lord!"

So, we are still really none the wiser at this juncture if truth be told.

Coochycool 31st Jul 2018 02:07

Havent finished reading the report yet, but the first raised eyebrow for me is the alleged high altitudes achieved on an aircraft we know had recently taken off carrying 49.1 tons fuel + 239 souls on board.

FL475 seems unlikely, but equally FL445 10nm south of Penang, if one is to believe the premise that a rogue pilot flew there intentionally for a last look of home.

The mil radar returns are noted as being of questionable value altitude wise which surprises me, but it still begs the question.....How high can a 772ER get thus loaded?

The parallel track with the Kota Bharu airway is also notable, suggesting "intentional manual input" indeed.

Intriguing how this saga has gone full circle, basically every theory under the sun has been thrown at it by every possible so-called expert and here we are back at square one with what is possibly a hijack scenario.

If this was a hijack I would suggest it runs to deep to ever be solved.

Oh, not this again............

ETOPS 31st Jul 2018 06:49

I was a Boeing 772 Captain for 4 years and regularly flew at FL410 - simply following the flight plan produced by the company. Even at high weights there was sufficient margin (the gap between VMO and the hockey stick) to allow occasional increases to FL420. That the certified max was FL420 wouldn't have worried someone who was trying "steal" MH370 and a climb above 42,000' might have been possible - I doubt FL475 was attainable and reckon the previously mentioned radar limitations are to blame for that figure.

As far as I know, there has only ever been one oxygen bottle that spontaneously ruptured....

Old Fella 31st Jul 2018 07:44

We can all speculate endlessly. A couple of things which I believe are, or at least could be, significant.
(1) The F/O was on his last training flight to type, and
(2) the opportunity existed for one pilot to lock the other out of the cockpit.

If either pilot left the cockpit and the other did lock the cockpit door it would have been a simple
matter for the lone pilot in the cockpit to don his oxy mask and depressurise the aircraft. Time
of useful consciousness, for those outside the cockpit without access to pressure breathing equipment,
would have been minimal leaving the handling pilot to disable the transponder and ACARS.
Of the two pilots it is reasonable to suspect the PIC would have the knowledge to do so. Why the
autopilot would have been disengaged, and for how long, is anyone's guess.

Whilst we may never find the answer my money would be on a deliberate act by one of the crew.

ETOPS 31st Jul 2018 08:17

Old Fella
My thoughts exactly - the combination of a flight sim available to practise the evasion, a willing trainee who simply would do as he was told (get me a bottle of water from the galley) and the mechanical deadlock in the door handle would give the Captain all the time he needed to carry this out. Single user of the flight deck O2 system gives many hours of continuous use allowing depressurisation and thus nobody conscious except him.

The question remains why?

Could it have been some suicide without leaving traces in order to secure his family the insurance payout?

Malaysia's civil aviation chief resigns in wake of MH370 report

Malaysia’s civil aviation chief Azharuddin Abdul Rahman resigned Tuesday after a report revealed that Malaysia Airlines flight MH 370 was likely deliberately steered off course and flew over the Southern Indian Ocean for more than seven hours after communications were severed.


I wonder why he waited so long. It's not like anything new was in the report. I also don't understand why he felt the need to resign in the first place. What's that going to accomplish?

birdspeed 31st Jul 2018 12:04

The report says they could find no one onboard with malicious intent. In the press conference the “inspector-in-charge” said the power failures to the communication systems(transponder,acars,satcom) were either turned off, OR power to them failed.

This means we are talking about a mechanical failure—an accident.

Yes, the inspector goes on to say ‘they cannot exclude the possibility of unlawful interference by a third party,’ but that’s because evidence is lacking either way.

The press have misinterpreted the reporting that the first turn was manually flown, and jumped to a conclusion it was a nefarious act—-WRONG.

The above should be the final report. Any normal thinking person knows this.

Coochycool 31st Jul 2018 13:04

Thanks for the reply ETOPS.

The elephant in the room here for me is this.....

https://en.wikipedia.org/wiki/Anwar_...s#Second_trial

Whilst I am normally loath to indulge what some might consider conspiracy theory, the coincidence here in known facts seems compelling.

The day before the MH370 incident, the leader of the Malaysian opposition party finally lost his long running legal battle on trumped up charges of sodomy, obviously designed to discredit and neutralise his threat. He was a known friend of the PIC. Giving the Captain possible motive to embarrass the standing government in the best way he knew how. We'll never know if this is what actually happened, but it does strike me as plausible.

The most disappointing thing about the final report must be that subsequent to Anwar's release and royal pardon upon the recent change of government, there still seems to be reluctance to discuss this aspect within MAS and political circles.
