faa to order jet insulation replacement - mylar insulation
On Wednesday, the Federal Aviation Administration announced that,S.
The airline will replace the insulation of 699 jets in the next four years, hoping to prevent fires like last fall near Nova Scotia that apparently caused fatal accidents.
The FAA order is intended to prepare airlines to meet the new, stricter aircraft insulation standards that the agency plans to release in a few months.
These new standards will effectively prohibit the use of metallized Mela insulation by airlines.
These changes are expected to cost airlines $0. 3 billion over four years, only for five aircraft-the MD-11, MD-80, MD-88, MD-90 and DC-10--
All of this was built in Long Beach by former Macdonald Douglas.
Now owned by Boeing.
The FAA operation is in the Swiss airline MD-
On September, 13 minutes after the flight crew reported smoke in the cockpit near Peggy Bay, Canada.
All 229 people on board-
The plane died.
Although FAA officials say they have seen few events, except for the Swiss Airlines crash, in which the flammable nature of the Mela insulation is a factor, they say the material is burning too fast and should be solved now.
The FAA's warning to Boeing and the FAA of more than 1996 has been slow, saying McDonald Douglas issued a warning to airlines on the issue on August 1996 and suggested replacing insulation.
Mylar is an approved material and when it is installed, its hazards are shown through subsequent tests.
However, the FAA also found in a separate test on 1997 that the Mela insulation material was extremely flammable and did not act immediately to order the removal of the material.
FAA officials admitted on Wednesday that the danger was an urgent issue only after the Swiss air crash.
The Swissair accident is still under investigation, but the Transport Safety Board of Canada released a report on Wednesday finding that the Mela insulation is a "significant source" of combustible materials that keep fire burning ".
The FAA order will be at 45-
The day of public comment did not meet the plan discussed by the agency in October.
The plan requires the replacement of insulation for almost all commercial aircraft.
But officials said recent tests showed that,
Mela insulated full flame-retardant.
Elizabeth Eriksson, director of aircraft certification at the FAA, said that most of the other insulation used on commercial passenger planes are now close to meeting new standards that are considered acceptable, and "will not pose a threat to aviation safety ".
Metallized Mela insulation, she says-
The trade name of a synthetic material called polyethylene O-benzene triacid ester or PET-
Proved to be more "easily lit" than other materials and "not through ["FAA's]
New standards have been substantially raised.
The FAA said the new order would apply to 699 of the United States. S. -
Registered aircraft are owned by American Airlines, Delta Airlines, Continental Airlines, Trans-World Airlines, Alaska Airlines, FedEx, Renault airlines, Mexican Airlines and American Airlines
The agency said 531 aircraft registered abroad also had insulation problems.
These jets are not directly regulated by the FAA, but officials say they often voluntarily comply with FAA orders because they often use American Airlines orders. S. airports.
Mylar, which is usually used to strengthen or protect other synthetic materials, is used to cover pillows-
Fiberglass-shaped wads are placed in the aircraft ceiling area before and after the cockpit wall and throughout the passenger compartment.
In a conference call with reporters, Eriksson said that the FAA would ask airlines to investigate their aircraft and first decide whether they contain metallized Mela insulation, and secondly, how can the material be replaced.
The airline will then be instructed to remove the Mela insulation and replace it as soon as it is practical ---
If possible, the next time the aircraft is regularly maintained.
Every airline will do the job on its own or contract it out.
The FAA estimates that these changes may cost airlines between $380,000 and $880,000 per aircraft, depending on the level and location of Mela's participation.
Insulation in the passenger area is easier to reach than in other areas.
The aviation industry representative reacted cautiously to the FAA statement.
Diana kelonan, spokeswoman for the Air Transport Association.
Airlines representing large airlines in the country said the industry was ready to work together to ensure safety on commercial aircraft, but expressed "concern" about the "premature movement" of the FAA ".
Airlines are concerned about two factors, she said: no one has changed the Mela insulation so widely, "we don't have a clear understanding of how it should be done . ".
The airline is also concerned that the work could cause "accidental damage" to the wires ".
Only a few other incidents occurred at Boeing.
Spokesperson Lori Gunte said her company wholeheartedly supports the FAA's efforts and said she would "force [the]
Our proposal [airline]
The operator was in 1996.
"Eriksson said that there were only a few incidents, except for the crash of the Swiss airline that was on fire with the Maitreya insulation.
Two recent incidents involved cargo planes.
The material itself, she said, is "not a security threat" only when [the Mylar]
There is a spark around.
"It was suggested that the fire on flight 111 of Swissair could have been caused by an arc in the wire.
Flight 111 from John F. , New York.
When Kennedy International Airport flew to Geneva, the crew in the cockpit was apparently shrouded in smoke from an internal fire.
The pilot's emergency landing in Halifax failed.
