Air India crash

[kgwilson]

10 out of 15 Boeing Engineers said in an interview they wouldn't fly on a Dreamliner. There are plenty of youtube videos citing Boeings problems and especially the problems with the 787.

The "Culture" Of Boeing is skewed to Profit above all else. Probably Accountant driven Union Hating and  establishing and sub contracting  NEW companies where work conditions are a bit wild and primitive. I've never been Keen on the Dreamliner but it does have colossal range. There was never any secret among those watching what was going on about Boeings workplace Culture and cost cutting. The short Undercarriage  limited the type of engines that could be fitted to the older 737's which already had rudder actuation Problems. causing fatalities . I chose to NEVER be endorsed on them.

The AAIB has released a statement saying they expect to produce a preliminary report by about July 11th. But the preliminary report will only be around 4 to 5 pages and just confirm basic details of the crash. However, it may also indicate the lines of investigation, and therefore the pointers to the cause of the crash.

 

The investigation is ruling out nothing at this point, and is including possible sabotage as one of the lines of investigation. This is not to say sabotage is suspected, only that they have to investigate the potential of sabotage, and examine any information (witnesses or black box evidence) that could increase the likelihood of any sabotage.

That there has been not even a hint of grounding airframes for any checks is at this point telling.

Certainly if no such recommendation comes in the next few days then Boeing will be relieved

An Air India plane plunged 900ft during its flight just two days after the disaster crash that killed 241 people onboard and dozens more on the ground, the airline has revealed. The plane, flying from Indira Gandhi International (IGI) Airport for Vienna, dropped 900ft in midair during a flight on June 14. It landed safely in Vienna following a nine-hour flight, but both pilots onboard have since been grounded pending an investigation by India's air watchdog, the Directorate General of Civil Aviation (DGCA), into the incident, Air India said.

Probably COMPLETELY Unrelated Causally. Just sensation. Nev

The trash media are using the altitude loss event of an Air India B777 to continue to smear Air India, and make it look like every AI aircraft is a crash waiting to happen.

 

Re Red750's report - The AI B777, Flight AI-187, took off from Delhi during a violent thunderstorm. On climbout, the aircraft obviously flew into a severe bout of turbulence and a heavy downdraught.

 

From official sources -

 

“The (B777) aircraft was involved in an inflight occurrence of stick shaker and GPWS caution. Soon after takeoff, stick shaker warning and GPWS 'don’t sink' caution appeared.  Stall warning occurred once, and GPWS caution occurred twice. There was an altitude loss of around 900 feet during climb. Subsequently, the crew recovered the aircraft, and continued the flight to Vienna."

 

However, officials pointed out that the post-flight report for the Delhi-Vienna leg only cited, “stick shaker due to turbulence after takeoff,” without detailing other significant alerts. A deeper review of the flight data recorder (DFDR) - most likely as part of increased surveillance after the AI 171 crash - had revealed additional warnings, including a “don’t sink” GPWS alert and a stall warning, that had not been documented earlier.

 

As a result, the flight crew have been temporarily suspended from further duties until the B777 altitude loss investigation is complete.

 

Possibly the major concern around this incident is the GPWS warning sounding, which indicates terrain was far too close to the flight path.

Long before all this I decided I would not fly on an indian crewed aircraft, not saying it was crew mistakes in this case, but there are just too many instances  of poor behaviour and crap CRM in Indian flight crews

 

Maybe my perception is not valid but its my persona position

[Litespeed]

I would think the lesson was don't go Boeing 787 until we know the cause of the crash.

If the people who build them won't fly then why should we.

Interesting news concerning the airline and possible culture/lack of training issues

Likely due to the Storms around. Normal procedure is to investigate and possibly recommend retraining or avoidance RADAR or use a higher  climb speed. Some planes have a thing like Alpha floor where the engines automatically go to a full power setting in such circumstances.  At lower altitudes there is a LOT of Reserve Power available on modern twin jet engined planes

[onetrack]

The GEnX engines in the Boeing 787 Dreamliner have increased thrust over previous models such as the CF6. The GEnX can generate up to 78,000 lbs of thrust at sea level, thus enabling the Dreamliner to take off with adequate power to spare, even at MTOW in high temperatures and high elevations.

[facthunter]

Nearly all take-offs are done with reduced thrust  to improve engine life.  Nev

Also prevents throwing a con rod. (Yep, know we’re talking jet engines, just and old saying) 

[facthunter]

It's about temps Cycles accumulating. You usually chuck a Rod  when changing gear at high revs.  It's a "specific" overstress.    Nev

[facthunter]

Conrods generally fail in tension. Changing direction near the top of the stroke. They want to keep going.  Nev
