    Bed in the Spirit AeroSystems integration

    With the December 2025 acquisition closed and ~15,000 Spirit employees folded into Boeing, the focus shifts to translating it into measurable quality gains - Boeing reports a 45% drop in 737 fuselage defects since 2024 - and stabilising rail deliveries of 737 fuselages from Wichita, which now builds more than 70% of the 737 MAX airframe, as the line ramps to 47/month and the new Everett North Line opens (July 6, 2026). Boeing backed the integration with a $2.35B Wichita reinvestment (announced May-June 2026) and, with Wichita State University's WSU Tech, a roughly 35,000-square-foot Boeing Workforce Training Center for aerospace technicians expected to open by the end of 2026.

    Reach a new SPEEA contract before the October 6 strike deadline

    TargetVote Sept 24-Oct 1, 2026; contract expires October 6, 2026

    Boeing and SPEEA reached a new tentative four-year deal on September 11, 2026 after members rejected the first offer on August 21. SPEEA's negotiating team is recommending a 10% guaranteed wage increase on the first pay period after ratification (expected October 2 if the vote passes), a 4% guaranteed increase in March 2027, and 6% annual wage pools for 2028-2030 with a 4% guarantee each year - a 36.3% compound increase for the average member versus 29.4% in the rejected offer. The Northwest Tellers Committee set the membership vote for noon PT September 24 through noon PT October 1. The current contract still expires October 6; a strike can start October 7 if members do not ratify. SPEEA-represented staff work on 737 MAX 10 and 777-9 certification, so the remaining gate is membership ratification. The Air Current reported on September 17 that Boeing has begun a soft hiring freeze and strike-contingency planning.

    737 MAX 10 certification

    Target~September-October 2026 (year-end 2026 at the latest)

    With the MAX 7 now certified (August 3, 2026), Boeing's remaining narrow-body certification work is the MAX 10, which completed its final planned certification flight on July 29, 2026 - closing out a campaign of 976 flights totaling more than 2,060 flight hours and roughly 1,040 ground-test hours. Remaining work is limited to development-assurance reviews, system-safety assessments, and final FAA submittals; Bloomberg reports the agency is expected to grant type certification around September or October 2026, with the FAA's public guidance still framing it as before year-end 2026. Certification clears the way for launch customers including United and Delta, with commercial deliveries expected to begin in 2027. Launch customer United - the type's largest customer with 167 firm orders - said on August 23, 2026 it now expects its first MAX 10 delivery in summer 2027 and is rethinking cabin plans after years of delay: hundreds of lie-flat premium seats originally bought for the jet have sat in storage, and United is leaning toward a higher-density domestic configuration (around 189 seats with recliner-style United First) instead of the lie-flat product it moved to the Airbus A321neo. A separate labor risk sits on the same window: SPEEA's current contract expires October 6, and Reuters said a strike could start October 7 if members do not ratify the September 11 tentative four-year deal covering about 17,000 professional and technical workers who work on MAX 10 and 777-9 certification. At Morgan Stanley's Laguna conference on September 16, 2026 CEO Kelly Ortberg said the MAX 10 will be certified 'very soon,' without naming a date.

    Issue updated 737 MAX go-around VNAV procedures to operators

In the news22

  1. FAA says 737 MAX software glitch is not a safety issue

    On Oct. 2, 2026 the FAA said its Corrective Action Review Board determined a software issue in certain Boeing 737 MAX flight computers is not a safety concern, because pilots retain full control and crew indications are clear and unambiguous. CNBC reported the finding paves the way toward 737-10 certification after the Sept. 28 hold; the FAA did not announce a type certificate. The agency said it would consider further action if it receives new information.

  2. FAA reviews 737 MAX software glitch on go-arounds

    Boeing told operators last month that 737 MAX flight-management-computer software versions 14 and 14.1 can drop vertical navigation after a missed approach if crews change the programmed path. The FAA said it will convene a Corrective Action Review Board. Southwest and United have asked Boeing not to deliver new MAX jets with the affected software, and Boeing said a permanent update is in work, originally aimed at 2028.

  3. Turkish Airlines firms up to 150 Boeing 737 MAX jets

    Boeing and Turkish Airlines finalized an order on September 23 for 100 737-8 jets plus options for 50 more 737 MAX aircraft, the airline's largest Boeing single-aisle purchase. The agreement, signed in New York with President Recep Tayyip Erdogan present, includes substitution rights for the still-uncertified 737-10 and industrial participation in Turkiye. It follows Turkish Airlines' 2025 order for up to 75 787 Dreamliners; Boeing did not disclose a contract value.

  4. FAA orders new 737 MAX bear-strap crack checks

    The FAA published Airworthiness Directive 2026-18-07 in the September 17 Federal Register, requiring inspections of the fuselage skin, bear strap, and stub frame at the forward galley-door cutout on certain Boeing 737-8, 737-9, and 737-8200 airplanes. The rule, prompted by reported cracks between stations 290 and 296, incorporates Boeing Alert Requirements Bulletin 737-53A1420 RB, covers an estimated 476 US-registered jets, and takes effect October 22, 2026. It is a separate directive from AD 2026-15-11, which took effect September 10; the FAA said Boeing is changing the manufacturing process on in-production airplanes.

  5. Lufthansa firms 20 Boeing 737 MAX 10 options

    Lufthansa Group said on September 17 that its Supervisory Board approved exercising options for 20 Boeing 737 MAX 10 aircraft, the group's first firm order for the largest MAX variant, lifting its firm 737 MAX total from 40 MAX 8s to 60 aircraft. Deliveries are scheduled to begin in the early 2030s as the jets gradually replace older Airbus A320-family aircraft across the group. The order has a list value of about $3.4 billion; Lufthansa has not named which airline will fly the MAX 10s and still holds 40 unused MAX-family options from the 2023 deal.
