• Engine transitions are a critical value inflection point in commercial aviation.
• Engines can represent over half of a narrowbody's total aircraft value.
• Traditional approaches to engine transitions are no longer sufficient.
• Engineering-led CAMO consultancy model is required for proactive risk management.

The increasing frequency of engine transitions due to ownership consolidation and aircraft movement may indicate a shift towards more proactive risk management strategies in the industry. This suggests that airlines and lessors could benefit from adopting engineering-led CAMO consultancy models to mitigate technical, financial, and operational risks associated with engine transitions.
