Yes No N/A

Photo evidence (optional)

Abnormal vibration, noise, or temperature observed in drivetrain components critical (required)

Document any unusual vibration, noise, or heat signatures that may indicate bearing wear, misalignment, imbalance, or lubrication issues.

Vibration reading captured at required measurement point

Blades, Hub, Pitch, and Yaw Systems

Blades free of cracks, leading-edge erosion, lightning damage, or delamination critical (required)

Yes No N/A

Photo evidence (optional)

Blade surface condition acceptable across visible span

Check for contamination, missing surface protection, impact damage, or abnormal wear patterns visible from the inspection point.

Photo evidence (optional)
