Air Cambodia Orders 20 737-8 MAX Jets; Boeing Probes 777X Seal, 787 Switch Defect

BABA

Boeing won an order for ten 737-8 MAX jets plus ten options from Air Cambodia, delivered 56.8% revenue growth in Q4 and held a backlog of over 6,100 aircraft. It also faced a 777X engine seal durability concern and a fuel control switch defect grounding a 787 Dreamliner in India.

1. Air Cambodia Places Landmark 737 MAX Order

At the Singapore Airshow on February 3, 2026, Boeing secured a firm order for 10 737-8 jets from Air Cambodia, with purchase rights for an additional 10 aircraft, marking the Cambodian carrier’s first acquisition of Boeing airplanes. The 737-8 offers up to 178 seats in a two-class layout and a maximum range of 3,500 nautical miles (6,480 km). Air Cambodia anticipates a 20% reduction in fuel burn and emissions compared to its existing fleet, enabling the launch of direct services to key markets across North and Southeast Asia. The order underscores Boeing’s strategy to expand its presence in Southeast Asia, where demand for single-aisle jets is projected to account for over 80% of nearly 5,000 new aircraft deliveries over the next 20 years.

2. Potential 777X Engine Seal Durability Concern

Boeing and engine partner General Electric have identified a potential durability issue with a seal in the powerplant of the 777X, according to Bloomberg News. The finding emerged during routine qualification testing and is under technical review by both companies. While GE assesses the seal’s long-term performance under cyclic thermal and pressure conditions, Boeing is evaluating any implications for the 777X certification timeline and initial delivery schedule. Investors are monitoring regulatory feedback, as any redesign or additional testing could push back the jet’s entry into service and affect production forecasts.

3. Air India Grounds Boeing 787 Over Fuel Control Switch Defect

Air India grounded one of its 33 Boeing 787 Dreamliners after a pilot reported a possible defect in the fuel control switch following a London–Bengaluru flight. This component was implicated in last year’s fatal Dreamliner crash in Gujarat, which killed 260 people when dual engine fuel cutoff switches activated simultaneously. The airline has inspected switches on its entire 787 fleet per a prior regulator directive and found no anomalies. Boeing is providing technical support, while India’s aviation authorities review the incident. Any further findings could prompt service bulletins or increased maintenance checks, potentially impacting 787 utilization and maintenance costs.

4. Boeing Q4 and Fiscal 2025 Performance Signals Growth Momentum

In its fiscal fourth quarter and full-year 2025 results, Boeing reported a 56.8% year-over-year revenue increase, driven by robust commercial aircraft deliveries and defense and services unit growth. The company delivered a record number of single-aisle jets, contributing to a backlog exceeding 6,100 aircraft valued at approximately $700 billion. Improved margin performance in its Commercial Airplanes division and sustained defense contract awards supported cash flow generation. Valuation metrics now align with industry peers, with analysts noting that delivery ramp-up and backlog visibility justify a modest valuation premium relative to the broader aerospace sector.
