The FAA subsequently grounded all models of the Boeing 737 Max 9 after the incident, leading to flight cancellations and frustration among airline executives. "Let me be clear: This won't be back to business as usual for Boeing," FAA Administrator Mike Whitaker said in a Wednesday statement. The agency has halted all further expansion production on Boeing 737 Max 9s until it is "satisfied" that the aircraft's quality control issues are resolved. In-house safety inspections of Alaska Airlines's fleet of Boeing 737 Max 9s following the initial incident revealed that there were "many" loose bolts found on the jets. The FAA's new safety guidelines for the 737 Max 9s come after a review of data stemming from 40 inspections of the grounded planes, the agency said.
