Boeing 787 (partie 2)

An Air India Boeing 787-800, registration VT-ANJ performing flight AI-301 from Melbourne,VI (Australia) to Delhi (India) with 215 people on board, was enroute at FL380 about 20nm north of Kuala Lumpur (Malaysia) when all three flight management computer system failed simultaneously. The crew diverted to Kuala Lumpur for a safe landing on runway 32L about 65 minutes later.

The airline reported a software malfunction caused the simultaneous malfunction of the FMCs. The passengers were taken to hotels. A replacement aircraft is expected to depart Kuala Lumpur on Feb 6th and is estimated to reach Delhi with a delay of 24 hours.

But the researchers say their discovery, detailed in journal The Proceedings of the National Academy of Sciences yesterday, paves the way for developing a new generation lithium-ion battery that doesn't spontaneously combust at high temperatures.
"There is a big demand for these batteries and a huge demand to make them safer," said DeSimone. "Researchers have been looking to replace this electrolyte for years, but nobody had ever thought to use this material called perfluoropolyether, or PFPE, as the main electrolyte material in lithium-ion batteries before."

Japan said on Friday the battery in a Dreamliner jet that spewed white smoke last month could have reached temperatures as high as 660 Celsius (1,220 Fahrenheit).
 
The figure came in an report released by the transport ministry after Japan Airlines grounded one of its Dreamliner planes when the smoke was seen outside the cockpit window during maintenance at Tokyo's Narita airport.
It was the latest in a series of problems that have beset the aircraft, including a months-long global grounding over battery problems last year.
According to the report, one of the eight lithium-ion cells in the plane's battery system "swelled and electrolytic solution was sprayed" out of the battery, a ministry official said.

Air India so far has 12 Dreamliners in its fleet out of the 27 it has ordered.

The sources said a team of Boeing officials have been categorically told that DGCA would be forced to take any action in the interest of flight safety if these issues were not resolved satisfactorily in a time-bound manner.

In a clear warning to the producers of the Dreamliners, DGCA chief Prabhat Kumar is understood to have reminded the American company that the Indian regulator had once grounded the entire new A-320 fleet of the erstwhile Indian Airlines in early 1990s on count of safety.

Since its induction two years ago till last month, Air India's Dreamliners have experienced 44 major engineering snags. Parliament was also informed few weeks ago that a total of 136 "minor" technical problems had occured in the fleet since its delivery began in September 2012.

The faults included nine counts of equipment failures, seven flight control issues, six cases of landing gear trouble, four of problems with navigational aids and three windshield cracks. Last year alone, the aircraft experienced 30 technical problems and there have been 13 such snags till February 24, according to official data.

DGCA told the Boeing team to submit a time-bound plan to fix the problems and submit a list of problems being faced by other airlines flying these aircraft along with the corrective measures taken.

The Indian regulator's move comes in the backdrop of the US regulator Federal Aviation Administration downgraded India's aviation safety ranking from Category-I to II.

Air India is also seeking compensation from Boeing for over three-year delay in delivery of the aircraft, global grounding of Dreamliners for four months last year and failure to meet "guaranteed performance standards" on various counts.

Boeing ne va pas se permettre un paquet de white tails   bien longtemps sur ses parking !
Bon, l'inventaire risque une certaine depreciation, c'est tout !
Peut etre pas exclu quand meme, qu'ils en fassent de la piece detachee, mais ils ne resteront pas sur leur tarmac !
