Boeing has indicated progress in certifying the 737 MAX 7 and 10 variants, but further delays remain a possibility. The certification process for these two airplanes has been a hurdle for Boeing following the grounding of the 737 MAX family in 2019 due to safety concerns. A key challenge emerged in January 2024 when Boeing withdrew a request for a safety exemption related to the anti-icing system on the 737 MAX 7. This system, also present on the MAX 10, raised concerns about potential overheating and damage to the engine inlet cowl.

While withdrawing the exemption request, Boeing projected a solution within a year. However, industry analysts at Air Current predict certification for both variants may not be finalized until late 2025. This timeline extends beyond Boeing's initial hope that the exemption would expedite the MAX 7 certification process. The exemption request aimed to allow the MAX 7 to be certified quickly with a temporary solution, while Boeing developed a permanent fix for implementation by May 2026. The FAA had previously approved a similar interim solution for the MAX 8 and MAX 9 models facing the same anti-icing system issue.
The potential overheating of the anti-icing system is a serious concern, as it could lead to a catastrophic failure of the engine nacelle, the housing that surrounds the engine. This scenario raises safety risks and could force grounded airplanes. Boeing remains confident in its progress on the certification process. The company is working on a permanent solution for the anti-icing system that addresses the overheating concerns. While this signifies progress, industry observers remain cautious due to the complexities involved in modifying an aircraft design and obtaining regulatory approval.
The delays in certifying the MAX 7 and 10 could have financial implications for Boeing. Airlines that have placed orders for these variants may face delivery schedule adjustments. Additionally, the delay allows Airbus, Boeing's main competitor, to solidify its position in the narrowbody aircraft market segment that the MAX 7 and 10 target. Despite the potential setbacks, the progress on the certification process suggests Boeing is nearing the finish line for the MAX 7 and 10. However, the lingering possibility of further delays underscores the ongoing challenges the company faces in getting these aircraft back in service.
