Fox News is reporting that the Federal Aviation Administration has banned a company from using stainless steel air bags in passenger-carrying airplanes.
The ban, which went into effect last week, has sparked a debate over the best way to keep airplanes running at low speeds.
The ban was part of the FAA’s efforts to limit the number of passenger-car crashes in the country, a key driver of the country’s economic growth.
The agency has been cracking down on the use of air bags, which are typically made of stainless steel and weigh more than a pound.
The FAA has been investigating the mufflers for more than two years, following a complaint from a California man.
The FAA is investigating whether the muffler, which is used in all of Boeing’s commercial airplanes, violated the Federal Motor Vehicle Safety Standard (FMVSS), the federal vehicle safety law.
The muffler’s makers are currently working to comply with the ban.
The National Transportation Safety Board has said that the ban is designed to prevent air bag-related crashes.
The safety board’s report said the ban does not appear to be effective.
In a statement, Boeing said it will continue to work with the FAA to address the safety concerns raised by the muffer’s makers and the safety of all of its customers.
The company has also announced a program to test mufflers on more than 400,000 passenger-flown aircraft.
It says that its engineers have identified more than 10 million miles of aircraft with the muffers in use and have been able to measure the performance of more than 100,000 of them.
