Early detection of cracks in helicopter gearbox casing is critical for safety and operational readiness. This work applies cyclostationary analysis combined with unsupervised clustering to analyze vibration data from a main rotor gearbox. Together, these methods improve early detection, reduce diagnostic uncertainty, and support predictive maintenance strategies for helicopters.
