787 grounded, but batteries can fly

WASHINGTON (AP)—
At the same time, the United StatesS.
The government has proved that the Boeing 787 Dreamliner is safe because of the risk of fire, and federal rules prohibit batteries used to power the aircraft\'s electrical system from being transported on the aircraft as cargo.
The situation is now reversed.
About three weeks ago, Dreamliners around the world stopped flying because lithium-ion batteries, part of the plane, caused a plane to catch fire and smoke in a second.
However, the new regulations exempt aircraft batteries from banning the use of large lithium-ion batteries as cargo on aircraft flights.
In fact, this means that the battery of the Dreamliner is now allowed to fly only if it is not connected to the Dreamliner.
The regulation was promulgated on January.
On the 7 th, a battery fire broke out on Japan Airlines Flight 787 at Boston Logan International Airport, and firefighters took nearly 40 minutes to put out.
The timing of these two events seems to be a coincidence.
Pilots and safety advocates say the situation makes no sense.
They say that if the 78 7 battery system is too risky to allow the aircraft to fly, it is too risky to ship the same battery as the cargo on the passenger plane.
\"These incidents raise the whole problem of lithium batteries and their use in aviation,\" said Jim Hall, former chairman of the National Transportation Safety Commission . \".
\"The transportation of lithium batteries for any use on commercial aircraft shall be suspended (an)
The NTSB survey has been completed and we know more about the whole issue.
\"Chesley\" Sully \"Sullenberger\" is a former American airline pilot who is known for precise flight, this allowed passengers and crew to fly in the cargo compartment in an emergency on the Hudson River in New York, he said in an interview that it was uncomfortable to fly a passenger plane carrying lithium-ion aircraft batteries.
\"The potential of self
\"The ignition is huge for fire that is not included,\" he said . \".
The new regulations \"need to be looked at very harshly in the cold weather, especially what happened with the 787 battery.
\"In order to meet the requirements of the United States, the battery rules have changedS.
In a statement, the federal Administration for Pipeline and Hazardous Materials Safety said that, as required by Congress, it meets the transport requirements of international standards.
International Civil Aviation Organization, United States of AmericaN.
The agency setting global aviation standards passed the aircraft battery cargo exemption on October 2011 and came into effect on January. 1.
The standards of the organization are generally not binding.
But a clause was inserted in the United States. S.
According to the requirements of the battery industry and its shippers, the law cannot be stricter than that of the United States. N.

Regulations prohibit the shipment of lithium-ion batteries on passenger planes weighing more than 11 pounds kilograms (five kilograms)
Although heavy batteries can be transported on cargo planes.
The new regulations allow the transportation of lithium-ion batteries weighing up to 77 pounds, but only if they are aircraft batteries.
Other lithium-ion batteries larger than 11 pounds are still banned from shipment.
Two batteries weighing 778 (29 kilograms)each.
This is the first passenger plane to use lithium-ion batteries widely, and lithium-ion batteries are smaller in weight and more in storage compared to other similar-sized batteries.
The aircraft battery exemption was created for the convenience of the aviation industry, which wants to be able to quickly ship replacement batteries to aircraft that run out of batteries or fail.
Sometimes it will be faster to use a passenger plane.
NTSB is investigating the cause of the 787 battery fire in Boston.
Japanese authorities are investigating a battery failure that led to an emergency landing of 787 of air carrier Japan on January. 16.
Since then, all Dreamliners operated by eight airlines from seven countries have been grounded.
International Air Transport Association representing the United StatesS.
Airlines for international flights and other airlines requested a waiver of aircraft battery charges at the US airlines meeting on October 2011N.
Dangerous goods Committee of the agency
The association believes that the exemption will allow airlines to \"have a lot of operational flexibility in moving aircraft batteries on passenger planes that may not be able to be used on routes, or in a short period of time, if a battery is needed, \"according to a copy of the request obtained by The Associated Press.
Since the battery must meet special safety standards in order to be installed on the aircraft, \"it is believed that it exceeds (11-pound)
\"Restrictions on passenger planes will not harm safety,\" the request said . \".
Some committee members opposed allowing lithium-ion aircraft batteries to be shipped on passenger planes, saying that the safety regulations that allow batteries to be used on aircraft do not necessarily ensure that batteries are transported safely as goods, according to the meeting summary published online by the United StatesN. agency.
\"A member is in their (country\'s)

\"The colleague did not believe that the test criteria for the installed aircraft batteries could provide special treatment for transport purposes.
\"It was pointed out that the safety standards applicable to batteries used in aircraft operation\" are strictly aimed at performance issues and how batteries interact with aircraft systems \", concluded \".
The summary did not identify committee members, but a source familiar with the deliberations said it was the United StatesS.
Representative Janet McLaughlin
A federal official familiar with the meeting said she abstained from the standard.
Neither source was authorized to comment publicly, and both spoke anonymously.
The plane landed in Boston, and nearly 200 passengers and crew got off the plane. About half an hour later, the fire of Japanese airlines was ignited.
After a cleaner working on the plane smelled smoke, the firefighters received an alarm.
It took nearly 40 minutes to put out the fire.
Deborah Hersman, current President of NTSB, recently told reporters that the \"multi-system\" designed to prevent 78 7 batteries from Catching Fire \"did not work as expected \".
\"The aviation expectation is never to experience a fire on a plane,\" she said . \".
Concerns about the battery transport of lithium-ion aircraft on passenger aircraft are not limited to batteries used in 787.
The Airbus A350, which is expected to go public next year, will also use lithium-ion batteries widely.
Aircraft manufacturers are also considering refitting some aircraft to replace batteries with lithium-ion batteries to reduce weight, according to the Airline Association.
The lighter the plane is, the less fuel it burns.
Fuel is the biggest operating expense for most airlines.
Pilots of cargo airlines have long complained about the dangers of transporting lithium batteries.
The batteries were suspected to have caused or contributed to the severity of an on-board fire that crashed on a joint Parcel Service plane near Dubai in September 2010, killing two pilots.
Two pilots of the other UPS aircraft were burned out by a fire shortly after landing in Philadelphia on 2006, but they barely managed to escape the plane. Lithium-
If the ion batteries are improperly packaged, damaged or have manufacturing defects, they may be short-circuited and ignited.
