737 MAX Grounding

The Boeing 737 MAX grounding occurred after two fatal crashes, caused mainly by a flight control system called MCAS that improperly pushed the plane’s nose down. Design flaws, lack of pilot information, and inadequate training led to tragic accidents. Regulators worldwide temporarily banned the aircraft from flying, prompting Boeing to modify the software, improve pilot training, and address safety concerns. The grounding lasted about 20 months before authorities determined the issues were resolved, allowing the 737 MAX to return to service with enhanced safety measures.
