Boeing's 737 MAX 7 and MAX 10 aircraft will not receive certification until 2026 due to ongoing complications with the engine anti-ice system. The majority of the global fleet, including the 737 MAX 8 and MAX 9 models, have been in service since their respective launches in 2017 and 2018. However, both the shortest-cabin MAX 7 and the stretched MAX 10 continue to face regulatory hurdles.
Airlines are waiting for these new variants, especially the larger MAX 10, but must now adjust their fleet plans as further delays have been confirmed. The issues stem from technical concerns related to the aircraft's engine anti-ice system, which has required additional review by regulators before approval can be granted.
Certification delays for new aircraft types can impact airline operations and future planning. The situation with Boeing’s latest MAX models is being closely monitored by industry stakeholders as they await resolution of these technical challenges.
