Boeing Co notified the FAA of the issue after it discovered structural cracks on an aircraft undergoing modifications in China. The FAA said subsequent inspections found similar cracks in a small number of additional planes. The FAA said planes with fewer flights will eventually get inspected. The order covers 1,911 U.S. registered planes.
The 737NG is the third-generation 737 and version before the now grounded 737MAX, which is not impacted by the issue. Boeing said Friday it has been in contact with 737NG operators about the discovery of cracks, but added that "no in-service issues have been reported."
