A pitch drive assembly is coupled to the blade pitch system and configured to rotate clockwise or counterclockwise within a range of angular degrees to adjust a blade pitch angle. The system includes a pitch lock pin-and-hole system including an interface plate and at least one blade pitch lock assembly coupled to the interface plate. Each lock assembly includes a locking pin having a pin center axis parallel with a center axis of a locking hole to engage a respective one locking hole of the set to lock the blade pitch angle.
