During a media briefing accompanied by a PowerPoint presentation, boeing aircraft
reiterated its confidence in the safety of both the 787 and 777 aircraft models. Senior engineers showcased extensive testing procedures aimed at refuting claims that approximately 1,400 Boeing planes may be afflicted by significant safety issues. The company addressed specific allegations, including concerns about gaps in manufacturing processes that could lead to premature fatigue failure over time.

The upcoming Senate hearing is expected to feature testimony from Boeing engineer Sam Salehpour, who has publicly criticized boeing airplanes safety practices and alleged retaliation for speaking out. Salehpour’s claims, currently under investigation by the FAA, include allegations of workers resorting to extreme measures during assembly, such as “jumping on pieces of the airplane” to align them.

Boeing officials stressed that thorough inspections of nearly 700 in-service Dreamliner jets revealed zero airframe fatigue findings, even after six and twelve years of heavy maintenance inspections. These results have been shared with the FAA, according to Boeing’s chief engineer, Steve Chisholm. He emphasized that the materials used in the construction of the 787 were specifically chosen for their resistance to fatigue and corrosion.

In response to Salehpour’s accusations of shortcuts in assembly processes, boeing planes
acknowledged instances where shims were not of the proper size and where areas did not meet skin-flatness specifications. However, the company dismissed claims of excessive force during assembly, stating that such practices were not part of their standard procedures.

China Developing Comac C939 Wide Body Aircraft to Compete with A350 and B777

China Developing Comac C939 Wide Body Aircraft to Compete with A350 and B777


China’s Comac aircraft company is currently underway with the development of its own wide-body aircraft, the C939, positioned to compete with industry stalwarts like the Boeing 787 and Airbus A350 in the future. This strategic move by Comac involves crafting the next iteration with enhanced capacity and extended range capabilities, marking a significant leap forward in technological advancement compared to the current C919 aircraft.

Air China has inked a substantial deal worth a staggering $10.8 billion, based on list prices, to acquire 100 Comac C919 jets, signaling a strong vote of confidence in the domestic challenger to aerospace giants Airbus and Boeing.

China Comac C919 Total Order

With both China Southern and Air China combining orders for nearly 200 aircraft, the prospects for the new C919 aircraft appear increasingly promising for future fleet growth. To date, Comac has garnered orders for nearly 1,100 aircraft.

China is contemplating the development of another wide-body aircraft, the C939, poised to significantly bolster the aerospace industry in China.

COMAC has initiated work on the C939, a new wide-body airliner. While design concepts have been formulated, it will still take several years before a prototype materializes, according to reports from the South China Morning Post, citing anonymous sources.

Initially intended to be a joint venture with Russia, plans were halted due to Russia’s decision to safeguard its copyrights and technological advancements within its borders. Consequently, collaboration between China and Russia on aircraft development was discontinued. Sources suggest that China is vigorously pursuing new avenues for the independent development of its own wide-body aircraft, crucial for accommodating larger passenger capacities and extended flight ranges.

Comac C939 competes with Boeing 777 and A350

Information regarding the program remains limited. COMAC has refrained from commenting on the development of the new aircraft type, stating that official announcements will be made in due course. Nevertheless, the C939 could potentially accommodate up to 390 passengers, positioning it to compete with the largest Boeing 777 and Airbus A350 aircraft.

In addition to the prospective C939, COMAC is already advancing with the development of another widebody aircraft, known as the C929. This aircraft is poised to rival the Boeing 787 and Airbus A330, boasting 280 seats and a range approaching 6,500 nautical miles.

Since obtaining certification in late 2022, the COMAC C919 has been operational, accumulating nearly 1,000 firm orders, predominantly from Chinese-owned airlines and leasing companies.

With multiple widebody aircraft in the pipeline, COMAC stands to achieve parity with the two leading international aircraft manufacturers. Boeing, with its 777 and 787 models, and Airbus, with the A330neo and A350, both have a comparable range of offerings. However, Boeing’s aircraft are encountering delays and production challenges despite substantial orders, while the A350 is performing commendably, though the A330neo’s order intake has not met initial projections.

How much does C919 cost?

China is under pressure to fulfill the current orders for the C919 aircraft, prompting plans to expand production facilities across various regions within the country. The aim is to ramp up production capacity for C919 planes to 150 aircraft annually over the next five years. The latest reports indicate that the C919 is priced around $99 million, comparable to the price of Boeing 737 Max and Airbus A320 aircraft, with expectations for further price reductions in the future.

While the C919 has yet to be certified in major aviation markets outside of China, only four have been delivered thus far. In the long term, COMAC’s widebody aircraft will vie for global competitiveness. One potential benefit of COMAC aircraft could be in reducing China’s reliance on Western aircraft manufacturers. However, this shift won’t happen immediately; the current delivery rate of four aircraft in nearly 18 months is not sustainable, and both Airbus and Boeing have established manufacturing facilities in China to cater to its sizable market.

Nevertheless, assuming COMAC addresses the issues impeding deliveries, there’s a plausible scenario where the manufacturer assumes a significant role, particularly as China’s aviation market continues to expand.

As the C939 progresses through its development stages, more details are expected to emerge. Comparisons between official specifications of the C929 and C939 will be noteworthy, as will the initial orders for each aircraft type. However, it’s anticipated that neither will undergo test flights or enter into service for several years.
