Boeing 737 MAX 7: a “considerably long” certification

2023-06-02 10:00:00

Certification of 737 MAX-7 takes “considerable time” due to new documentation requirements, according to an official from Boeingeven though the aircraft had been used to recertify the MAX 8 and then the MAX 8200. The CEO, for his part, asks for the patience before the release of new plane.

The new requirements of the Federal Aviation Administration (FAA) simply in numbers of documents requested from the American aircraft manufacturer makes ” considerably long ” the certification of the 737-7the smallest of the re-engined single-aisle family, according to Mike Fleming, senior vice president of development programs and customer support at Boeing quoted by Aerotime. But the ” final documents » are in preparation, and its certification should take place by the end of the year. It won’t be before 2024 for the 737 MAX 10even if the manager is confident that he will soon obtain the green light from the FAA to begin certification flights.

Since Boeing got the green light to the status quo from Congress last December (bypassing the FAA’s deadline for certifying both models without changes to the security systems), few statements have been made officially on the subject of MAX certification. Recall that the MAX 8 had been recertified in the USA in November 2020 – 616 days after the last commercial flight of a MAX, following the two accidents which caused 346 victims at Lion Air then Ethiopian Airlines (371 MAX 8 and MAX 9 had been grounded). Flights verifying the modifications of the MCAS involved in the two crashes had been operated – in 737 MAX 7…

During the same press conference where an acceleration of the production of the 787 was announced, the CEO of Boeing Dave Calhoun for his part assured that the ” existential crisis of the MAX was in the process of being absorbed, even if deliveries to China have still not resumed (the country accounts for 140 of the approximately 230 MAX crammed in the parking lots of the aircraft manufacturer). As for the 787 Dreamliner, he estimates that around 90 aircraft are grounded due to quality issues (discovered by Boeing). For both devices, these “inventories” should be gone by the end of 2024.

After “killing” the NMA project in early 2020 shortly after his nomination, Dave Calhoun asked again “ patience » before the release of a new plane. With the same reasoning as last June, when he explained that lack of “technological leap” in motorization airliners, the financial risk was not justified. Even if GE and Safran, partners in CFM International, estimate that their Open Fan will bring a 20% improvement in consumption compared to their LEAP equipping the 737 MAX and A320neo.

« This mid-market aircraft, we’re not going back to what this design was. I never even looked at it. We’re just going to keep moving forward with the technologies we have. “, declared the CEO according to Leeham News, refusing to say whether the next plane will be single-aisle or twin-aisle. THE materials composites used in the 787″ can’t be ignored “, he added on the other hand, while noting that the Transsonic Truss-Braced Wing concept developed with NASA for example does not apply to large capacities. ” That’s the best I can tell you. I know everyone would love for me to get up here and design the new plane for you. It’s not gonna happen », a conclu Dave Calhoun.
