FAA Approves Test Flights Of Boeing's Updated 737 Max Jet

The FAA has approved test flights for the Boeing 737 Max as part of its recertification process. The aircraft was grounded globally in March 2019 after two fatal crashes linked to its automatic stall prevention system. Boeing has been working on a software update, but recertification has been delayed due to additional technical issues. The FAA's clearance process involves multiple steps, including test flights and approval of pilot training programs. International regulatory approvals from Europe and Canada are also required.
