Chinese aviation expert Xia Xiaofeng says some high-pressure turbine blades in GE Aerospace's GEnx engines on Boeing 787 aircraft may crack after about 1,000 flight cycles, earlier than expected, and in some cases lose material. One airline's 787 fleet recorded 5 engine removals due to high-pressure turbine blade defects in Phase 2 and Phase 2+ versions, but the study does not show that all GEnx engines or fleets face the same problem. In this context, the US FAA has issued several directives on GEnx turbine disks, compressor parts and fuel lines, but these are not direct evidence of the blade cracking described. There is not yet enough information to conclude that the cases share a common cause, and airlines could face inspection and replacement costs and operational disruption if engines must be removed. The article stresses that more data from the manufacturer and aviation regulators is needed to assess the scope of the issue.

- Boeing wins FAA approval for 737 Max 10 after years of delays
The FAA certified Boeing's 737 Max 10 on Tuesday after years of delays, making it the last model in Boeing's best-selling jet family to receive government approval. The approval came weeks after federal officials reviewed a navigation system glitch and deemed it not a safety-of-flight issue. The Max 10, the largest model in the family, was originally slated to fly in 2020, but heightened scrutiny after two Max crashes in 2018 and 2019, along with other safety issues including engineering changes to an engine anti-icing system, delayed certification. Orders for this aircraft make up about 30% of Boeing's backlog, with customers including Alaska Airlines, American Airlines, United Airlines and Delta Air Lines. United's CEO said the lie-flat seats the airline expected for the plane are now sitting in a warehouse because the wait was so long.
- Boeing and Airbus Planes Seat 200, China's Only 19, but It's the Engine the World Admires
COMAC has released images reportedly showing a full-scale test model of the all-electric 19-seat CE-25A, though there is no official confirmation that it has flown. The aircraft was first unveiled at the China International Import Expo in 2023, with a cruise speed of about 400 km/h and a range of 400 to 500 km for short- and medium-haul travel. Its distinctive feature is distributed electric propulsion, with 10 fans integrated into the wings, but the article stresses challenges such as low battery energy density, thermal management and reliability. By comparison, the Beechcraft 1900 carries up to 19 passengers about 700 km at roughly 520 km/h. Similar projects are underway in Europe (UNIFIER-19), the US (NASA's X-57A, cancelled in 2023) and France (AURA AERO's ERA).
- Boeing Stock Slumps Again; Time to Buy or Throw in the Towel?
Boeing shares fell again after management cut its outlook, with the 737 MAX production ramp-up delayed by up to a year and free cash flow (FCF) forecasts below consensus. FCF is projected at $2 billion in 2026, $3 billion in 2027, $6 billion in 2028 and $10 billion in 2029, versus Visible Alpha consensus of $5.3 billion, $9.5 billion and $12.4 billion for 2027–2029. The 777X certification, expected by mid-2027, followed by first delivery, is a major risk, as delays would keep more cash tied up in undelivered aircraft. The author estimates that if Boeing reaches $10 billion in FCF in 2029 and trades at 20 times FCF, the share price would be about $252, an annual return of 14.4% to 2029, and considers management's 2027–2029 production targets conservative. The author says the stock looks attractive after the reset if production targets are met, though volatility is likely, and points to a $745 billion backlog.
- Boeing's Backlog Grew to $745 Billion. The Question Remains How Fast It Can Fulfill It
Boeing reported an adjusted loss of $0.34 per share, worse than the $0.21 loss Wall Street expected, although revenue of nearly $24.2 billion beat the $23.84 billion forecast. Its total order backlog hit a record $745 billion at the end of September, including over 6,300 commercial airplanes and up about $30 billion from the prior quarter. However, CEO Robert Kelly Ortberg said the 737 Max has not yet reached its stability rate of 47 per month and may not be fully stable at that rate until next year, pushing the target of 52 per month to the second half of 2027, and the stock fell nearly 10.7% on Oct. 27. The 737 Max 10 recently received FAA certification and has over 1,500 orders, while the U.S. Navy selected Boeing for a $20 billion contract to build its sixth-generation fighter aircraft. Ortberg expects free cash flow of about $2 billion this year and $10 billion by 2029, below the $12.5 billion Wall Street consensus had modeled for 2029 before the report.
- Boeing shares slide on a disappointing cash flow update. Why this dip is buyable
Boeing shares fell about 10% on Tuesday to a fresh 52-week low after the company gave long-term free cash flow guidance below expectations, even though third-quarter revenue of $24.19 billion rose 4% year over year and beat forecasts. Free cash flow of $464 million beat the $330 million expected, and Boeing kept its $2 billion expectation for 2026. However, it now sees free cash flow of $3 billion in 2027 and $6 billion in 2028, reaching its $10 billion target in 2029, a year later than Wall Street had modeled. The company ended the quarter with a record $745 billion backlog, and CEO Kelly Ortberg said customer demand has not changed. The author views the report as a clearing event, reiterating a buy-equivalent 1 rating while lowering the price target to $225.
- The big reason Boeing's stock is falling so hard after earnings
Boeing expects to fall short on 737 Max deliveries, which casts doubt on its turnaround plans.

- Many people send money to hackers asking for a cut of the Binance theft
Wallets holding 18,270 bitcoin stolen from Binance keep receiving small transfers from strangers with messages asking for a share, though none of these messages has drawn a reply. The senders have spent about $46 in BTC on them, excluding transaction fees. Others urged the hacker not to return funds to Changpeng Zhao or to accept deals with white hat researchers, while some used the attention to promote their own tokens. As of Nov 1, the attacker had begun swapping 970,522 stolen SOL, worth about $96 million, into bitcoin, and the breach is estimated at about $6.3 billion, with roughly $2.7 billion frozen by token issuers and partners. Binance says it has covered about 95% of the stolen value and is processing withdrawals in stages, but it has not published a full technical report, and US authorities have linked the group to North Korea.

- Global oil prices fall sharply
World oil prices fell nearly 4% on the afternoon of Nov 2 as Iranian and Qatari officials held talks for a third straight day to advance a deal ending the war. Brent crude dropped 3.2% to $109.8 a barrel and WTI fell 3.6% to $100, after Brent closed October at a six-month high on fears that Middle East conflict would flare up again. The talks come after oil tankers transiting the Strait of Hormuz were recently attacked, pushing up global energy and shipping costs. Analysts said global crude is unlikely to top $120 a barrel because the risk of escalation through year-end is already priced in, and oil flows through Hormuz and alternative routes have recovered to nearly 80% of pre-war levels. OPEC and its allies kept their December output targets unchanged and are unlikely to adjust production until next year.
- Apollo launches $11 billion private credit platform, backed by Abu Dhabi

Apollo president Jim Zelter said financing needs from energy transition, defense and digital infrastructure are acutely felt in Europe.
