Senator Tammy Duckworth, who chairs an aviation subcommittee, said last week she opposed Boeing's exemption request that would "prematurely allow the 737 MAX 7 to enter commercial service." She noted the exemption Boeing had sought "involves an anti-ice system that can overheat and cause the engine nacelle to break apart and fall off. This could generate fuselage-penetrating debris, which could endanger passengers in window seats behind the wing."
