Big Boeing 777X Update

The Boeing 777X has ticked up yet another milestone in its pathway to certification.

Roxavgeek reported, with thanks, to the Boeing 777X lovers fan page that the aircraft had been granted Type Inspection Authorisation (TIA) Phase 2D.

Now, the program moves into phase 3 as the process continues to ramp up, with Boeing attempting to seek the necessary approvals for the jet to receive its all-important stamp of approval for a launch sometime in 2026.

Phase 3 will be similar to Phase 2, involving a wide array of evaluations that will be conducted on the business as progress is finally made positively for the jet.

Included in the next phase are examinations of the reliability of the avionics and the integrated landing systems to determine how these processes interact throughout the plane and whether their interaction is as seamless as required.

Other areas include the certification of interior doors and crucial cabin systems to ensure they’re compliant and safe for use, with functionality tests also being conducted.

P-static testing will also be conducted, which is part of an overall verification process to ensure the systems remain unaffected by precipitation-induced static buildup.

Next, the stability and control checks will continue, a fundamental part of all phases and evaluations on the pathway to certification, as Boeing and the FAA work to understand whether the handling qualities are safe and reliable irrespective of the condition.

The APU will be tested with high performance and evaluated in various operational environments to determine its reaction. Through this, the rate of efficiency can be determined.

Lastly, climate management is also on the planemaker’s list with the cabin management to be studied, which will directly impact the passengers and crew aboard the plane.

The Latest On The Boeing 777X

It has been a busy period for the Boeing 777X, with significant progress on the certification process as the business moves ahead and remains on target for approval in 2026, with a corresponding 2026 delivery.

These ticks on different phase certifications follow a lengthy certification period that has been ongoing for some time, but has been necessary due to the scrutiny surrounding how new planes are approved, especially Boeing’s by the FAA, following the numerous quality slips that have emerged on other aircraft programs driven by negligence at various stages.

Boeing also scored further love for its new long-haul product in recent days, with Korean Air placing its largest-ever single aircraft order. For the planemaker, this was its largest widebody deal with Asia.

The purchase included 20 additional Boeing 777-9s, bringing the total commitment to the series and ensuring the 777X will play a fundamental role in Asia moving forward, alongside customers such as Cathay Pacific, ANA, and Singapore Airlines.

Away from new deals, which have been coming in thick and fast for the 777X after a lengthy period of lacking firm interest, there’s a general feeling that progress is finally moving in the right direction.

If all were to continue to stick to schedule, the 777X would be certified six years later, and by the time it enters service with scheduled passenger airlines, seven years would have passed due to the required crew familiarisation.

The delays for the program have been hard to ignore, but these are the cards the 777-9 has been dealt, and Boeing knows it must move forward with a positive mindset and change the narrative surrounding its commercial aeroplane division.

Certainly, therefore, the only way to change the narrative surrounding the delays with the 777X and ease the frustrations expressed by customers is to obtain certification once and for all, secure approval, and start delivering the type sooner rather than later, but still in the safest manner possible.
