FAA Gives the Public 45 Days to Comment on the Boeing 737 MAX

Boeing will 'very shortly' increase 737 MAX manufacturing to 38 per month.

In the near future, the FAA plans to issue a Notice of Proposed Rulemaking (NPRM) for an Airworthiness Directive (AD) affecting the Boeing 737 MAX. In keeping with our commitment to remain transparent, the NPRM will provide 45 days for the public to comment on proposed design changes and crew procedures to mitigate the safety issues identified during the investigations that followed the Lion Air and Ethiopian Airlines accidents. 

The agency continues to follow a robust certification process. In addition to the standard FAA certification team, the 737 MAX Technical Advisory Board (TAB) continues to provide valuable review and consultation.

While the posting of the NPRM is an important milestone, a number of key steps remain. The remaining tasks include:

  • JOEB Validation & FSB Review – Final planning is underway for the FAA’s Flight Standardization Board (FSB) and the Joint Operations Evaluation Board (JOEB) review of proposed training for flight crews, based on the design change and crew procedures. The results of this evaluation will be included in the updated Flight Standardization Board report, which will also be posted for public comment.
    The JOEB will include regulators from Canada, Europe, and Brazil and will evaluate minimum pilot training requirements. The FSB will issue a draft report for public comment addressing the findings of the JOEB.
  • Final FSB Report – The FAA will publish a final FSB report after reviewing and addressing public comments.
  • Final Design Documentation and TAB Report – The FAA will review Boeing’s final design documentation to evaluate compliance with all FAA regulations. The multi-agency Technical Advisory Board will also review the final Boeing submission and issue a final report prior to a final determination of compliance by the FAA.
  • CANIC & AD – The FAA will issue a Continued Airworthiness Notification to the International Community (CANIC) providing notice of pending significant safety actions and will publish a final Airworthiness Directive (AD) that addresses the known issues for grounding. The AD will advise operators of required corrective actions before aircraft may re-enter commercial service.
  • FAA Rescinds Grounding Order – This marks the official ungrounding of the aircraft, pending completion by operators of the work specified in the AD, along with any required training.
  • Certificates of Airworthiness – The FAA will retain its authority to issue airworthiness certificates and export certificates for all new 737 MAX airplanes manufactured since the grounding. The FAA will perform in-person, individual reviews of these aircraft.
  • Operator Training Programs – The FAA will review and approve training programs for all Part 121 operators.

The FAA will not speculate when the work will be completed. The agency continues to follow a deliberate process and will take the time it needs to thoroughly review Boeing’s work. We will lift the grounding order only after FAA safety experts are satisfied that the aircraft meets certification standards.

COMAC Unveils Plans for the C929 to Rival Airbus and Boeing

COMAC Unveils Plans for the C929 to Rival Airbus and Boeing

After the success of China’s first C919 aircraft, the country is setting its sights on developing a larger plane. COMAC (Commercial Aircraft Corporation of China) has officially confirmed plans to build a widebody aircraft, marking a significant step in its aircraft lineup.

Traditionally, Airbus and Boeing dominate the widebody aircraft market, with decades of expertise in developing planes and engines capable of carrying heavy payloads. China, which currently relies on imported engines, is now aiming to challenge these giants with its own widebody jet, the C929, designed to compete with the Airbus A350 and Boeing 777.

The C929 will be China’s first independently developed long-range widebody aircraft. It adheres to international airworthiness standards and boasts independent intellectual property rights. The baseline version is designed to seat 280 passengers and offers a range of 12,000 kilometers, catering to global demand for both regional and international air travel.

Russia, which also needs reliable narrowbody and widebody aircraft, could become a key customer for the C929. Additionally, China plans to target the broader Asian market as it continues to expand its aviation capabilities.

China’s aviation progress includes the ARJ21 (now called C909), a regional jet with 100 seats for shorter routes, and the C919, a narrowbody jet with 180 seats designed to rival the Boeing 737 MAX and Airbus A320. Both models have found increasing demand in the domestic market.

At China’s largest air show in Zhuhai, COMAC announced that Air China will be the launch customer for the C929 widebody jet, though details about order size and delivery timelines were not disclosed.

Other major deals announced by COMAC include:

  • Hainan Airlines: Firm orders for 60 C919 and 40 C909 regional jets.
  • Colorful Guizhou Airlines: 30 C909 jets, with 20 firm orders and 10 provisional agreements.

The C929, renamed from the CR929 after Russia withdrew from the joint development project in 2023, is expected to carry 280–400 passengers with a range of 12,000 kilometers, competing directly with Boeing’s 787 Dreamliner.

According to COMAC’s deputy general manager, Tong Yu, the first fuselage section of the C929 is expected by September 2027, with prototype test flights anticipated soon after.
