Boeing 777X Certification May Not Happen Until 2027, Affecting Deliveries

Boeing 777X Certification Faces Potential 2027 Approval, Impacting Delivery Schedules

The certification of Boeing’s new 777X aircraft is facing potential delays, with FAA Administrator Bryan Bedford indicating that approval might not come until 2027. This timeline shift places increased pressure on Boeing’s planned delivery schedule, which aims to begin next year. The company has already experienced significant delays and financial charges related to the 777X program.

Boeing CEO Kelly Ortberg stated on May 27, 2026, that the majority of the flight-test program should conclude by the end of 2026. However, Extended-range Twin-engine Operational Performance Standards (ETOPS) testing is expected to continue into the following year. Despite these ongoing tests, Ortberg expressed confidence that Boeing is “building the airplanes and getting ready to start the deliveries next year.” This statement suggests Boeing is proceeding with manufacturing and preparation for customer handovers, even as certification processes extend.

The 777X program has already undergone revisions, with a previous adjustment in October 2025 moving the first delivery target to 2027. This revision also included a pre-tax charge of $4.9 billion. Originally, the aircraft was expected to enter service in 2020, meaning a 2027 certification would place the program approximately seven years behind its initial schedule.

Bedford’s comments highlight that the current delays are procedural rather than stemming from new technical issues. This distinction is important for stakeholders assessing the program’s remaining risks. The focus has shifted from whether Boeing can fix technical problems to how much time the Federal Aviation Administration (FAA) will need for its certification process.

If FAA certification occurs early in 2027, Boeing might still be able to complete some aircraft deliveries within that year. However, a later approval would significantly compress the handover period. This compressed timeline could complicate essential post-certification activities, such as airline training programs and the planning required for the aircraft’s entry into service.

Airlines that plan to introduce a new long-haul aircraft type must coordinate pilot training, operational procedures, and route launches. A shorter window between certification and the planned service entry makes these preparations more challenging to manage effectively. Boeing’s current strategy appears to be preparing for deliveries in 2027, even with ongoing testing and a potential 2027 certification.

The GE9X engine’s mid-seal durability fix has been addressed by Boeing and GE Aerospace, who state it is not expected to impact the planned delivery timing. This suggests that the primary obstacle now lies in the pace and sequencing of the FAA’s certification review. The FAA’s indication that 777X certification will follow the completion of remaining 737 MAX certification work places the 777X in a queue, potentially affecting its timeline regardless of Boeing’s testing progress.

This situation creates a gap between manufacturing readiness and certification readiness. While Boeing can continue building aircraft and preparing them for delivery, the actual handover of planes to airlines is contingent upon the FAA’s final approval. The tension between these two timelines is a central aspect of the 777X’s current status. Boeing is building aircraft and aiming for 2027 deliveries, while the FAA’s certification process may extend into that same year.
