• •US investigators identified a fractured engine fan blade as the cause of the decompression incident
• •The failure occurred during a Ryanair flight last month, triggering an emergency response
• •Officials have not yet confirmed the specific metallurgical cause behind the blade's structural fracture

A preliminary investigation has officially linked last month's Ryanair mid-air decompression event to a fractured engine fan blade. While such incidents are rare, the aerospace industry typically tracks these failures through stringent inspection cycles to prevent catastrophic engine loss. Investigators have yet to determine if the failure was caused by metal fatigue, a foreign object strike, or a manufacturing defect. The findings are expected to prompt a review of maintenance logs for similar engine models across the regional carrier's fleet.
