"NTSB Reports Missing Bolts on Boeing 737 Max Planes"
The National Transportation Safety Board's preliminary report revealed that four bolts were missing from a door panel that blew out of an Alaska Airlines Boeing 737 Max 9 plane last month, causing cabin depressurization and minor injuries to passengers. The report raised concerns about Boeing's manufacturing procedures and prompted the FAA to consider a heavier-handed approach to monitoring the company. Boeing has pledged to review the findings and implement a quality control plan, while also addressing another issue with incorrectly drilled holes in some 737 Max planes. These incidents come after the 737 Max 8 crashes in 2018 and 2019, and the NTSB's investigation into the recent door plug failure is ongoing.
