Boeing 777-9 Gains FAA Approval, Nears Certification Milestone

After years of delays, Boeing’s long-awaited 777-9—the flagship of the 777X family—has received FAA approval to advance into a new phase of certification testing. This marks a pivotal step forward for Boeing as it seeks to restore industry confidence and deliver its next-generation widebody jet.

Originally expected to enter service in 2020, the 777-9 program has faced multiple hurdles, including issues with the GE9X engines, software delays, and increased regulatory scrutiny following the 737 MAX crisis. Despite the setbacks, Boeing has logged over 4,000 flight hours across its test fleet. The latest approval under the FAA’s Phase 2C Type Inspection Authorization (TIA) allows formal system evaluations to proceed.

The FAA has approved the Boeing 777-9 for a new phase of certification testing, focusing on demonstrating the aircraft’s systems and flight performance under various conditions. This includes tests simulating ice formations, evaluating braking performance on wet runways, and assessing the aircraft’s behavior in extreme weather conditions like strong crosswinds. The certification process is crucial for the 777-9’s entry into service and is a significant milestone for Boeing. The successful completion of these tests could help Boeing regain its leadership position in widebody manufacturing.

The 777-9 is designed to carry up to 426 passengers in a typical two-class layout and offers around 20% greater fuel efficiency than previous 777 models. Notable innovations include composite folding wingtips, enhanced aerodynamics, and the powerful GE9X engines—the largest turbofans ever built.

With 551 total orders in the 777X backlog, Emirates is the largest customer with 170 aircraft on order. Lufthansa is expected to be the launch operator, likely introducing the 777-9 into commercial service by late 2025 or early 2026.

As Boeing prepares to add a fifth test aircraft and finalizes system validations, the 777-9 faces stiff competition from the Airbus A350-1000, or it might launch a new version the -2000. But more than a new aircraft, the 777-9 symbolizes Boeing’s determination to rebuild trust, meet modern performance standards, and reassert itself in the long-haul market.
