Two airlines find loose bolts on Boeing 737 MAX 9 jets
The findings come after the Federal Aviation Administration grounded all 171 of the 737 MAX 9 planes operated by US airlines after a window and chunk of fuselage blew out of one Alaska Airlines aircraft shortly after it took off from an airport in Portland, Oregon.
Two US airlines say they have found issues with door bolts on their Boeing 737 MAX 9 jets. Alaska and United Airlines said they had discovered "loose hardware" on their fleet of airliners.
