Boeing Completes 777-9 Brake Test After Challenges

Boeing has successfully completed runway brake certification tests for its next-generation 777-9 widebody jet, marking a major milestone for the long-delayed program. The tests wrapped up after an intensive two-month campaign that required round-the-clock maintenance shifts and tight coordination between teams in Oklahoma and Seattle.

According to company officials, the brake certification program faced multiple logistical and technical hurdles that had to be overcome to keep the aircraft on schedule. Remote engineering teams worked closely with on-site crews to troubleshoot issues and ensure the tests met regulatory standards. The effort underscores Boeing’s determination to move the 777X family toward certification and entry into service.

The 777-9, the largest twin-engine commercial aircraft ever built, features new GE9X engines, a composite wing with folding wingtips and updated avionics designed to deliver improved fuel efficiency and lower operating costs compared to current-generation widebodies. Brake testing is a key part of the aircraft’s certification, ensuring the airframe can safely stop under maximum weight and adverse conditions.

Industry analysts view the successful completion of the brake tests as a sign of progress for Boeing’s flagship widebody program, which has been delayed by supply chain challenges, certification changes and stricter regulatory oversight following recent safety issues.

With this milestone achieved, Boeing can advance to additional certification phases and flight testing, moving the 777-9 closer to its planned entry into service and reinforcing its competitiveness against the Airbus A350 in the long-haul market.
