DALLAS (AP) — Boeing is asking federal regulators to exempt a new model of its 737 Max airliner from a safety standard designed to prevent parts of the engine housing from overheating and breaking during flight. .Thank you for reading this post, don't forget to subscribe!
Federal officials said last year that Boeing was working to fix the threat on existing MAX planes. In the meantime, he told pilots to limit the use of the anti-icing system in certain situations to avoid damage that “could result in loss of control of the airplane.”
Without any improvements, Boeing last month asked the Federal Aviation Administration to waive safety standards related to engine inlets and anti-ice systems through May 2026. Boeing needs the waiver to begin deliveries of the new, smaller Max 7 to airlines.
Some critics are concerned about creating a safety ground for pilots to remember when to limit use of the anti-ice system.
“When you say people could be killed, we pay attention to you,” Dennis Tajer, a spokesman for the American Airlines pilots, told The Seattle Times. “We are not interested in seeing exemptions and accommodations that rely on human memory… There just has to be a better way.”
Pilots flying the Max 8 and Max 9 have been warned to limit use of the anti-icing system to five minutes when flying in dry conditions. Otherwise, the FAA says, the inlets around the engine could get too hot, and parts of the housing could break off and hit the plane, possibly breaking windows and causing rapid decompression.
That’s what happened when an old 737 engine fan blade broke during a Southwest Airlines flight in 2018. A piece of the loose engine housing struck the window and broke it, killing a woman sitting next to the window.
The overheating problem only affects the Max, which has engine inlets made of carbon composite material instead of metal.
Boeing did not immediately respond to The Associated Press’ request for comment.
