Which risk increases when a helicopter's rotor blades experience retreating blade stall?

💡 Explanation

Retreating blade stall happens because the advancing blade's lift increases as the retreating blade's lift decreases, leading to asymmetric lift; therefore, control is lost rather than engine failure, because blade asymmetry is the dominant issue.
