HeyEng Posted February 8 Share Posted February 8 (edited) There is also an issue with the engine anti-ice. The LEAP engine nacelle lip uses more composite materials than the legacy nacelles and can catastrophically fail if the anti-ice is left on in dry conditions for more than five minutes! The AD warns this could result in “an un-powered off-field landing”! https://www.federalregister.gov/documents/2023/08/10/2023-17197/airworthiness-directives-the-boeing-company-airplanes Edited February 8 by HeyEng Link to comment Share on other sites More sharing options...

Not a real shocker. 1 Link to comment Share on other sites More sharing options...

That's the definition of a "real shocker." 1 Link to comment Share on other sites More sharing options...

Not a real shocker. And of course anti-ice valves never stick in the open position! Boeing has auto anti-ice systems that automatically turn on and off during icing conditions but to maintain the same type rating as legacy 737 aircraft, these type of systems are not installed on the Max. The Max with the LEAP engines should have had a new type certificate but Southwest would have not have purchased the aircraft to begin with and so Boeing did a lot of pounding a square peg in a round hole to emulate handling characteristics of legacy 737. Even the NG had a different wing and cruised faster than the 100 to 600 aircraft and it could be argued that Boeing should have changed the type certification back then.
