HE DECLARED AN EMERGENCY AND LANDED WITHOUT FURTHER INCIDENT. AN INVESTIGATION REVEALED THAT THE INBOARD TRAILING EAR OF THE MAIN ROTOR SLEEVE/SPINDLE ASSEMBLY, PN 330A31-002607, FOR THE BLUE BLADE, HAD FAILED. EVIDENCE OF FATIGUE WAS FOUND OVER MOST OF THE FRACTURE SURFACE AND EVIDENCE OF FRETTING CORROSION WAS FOUND AT THE ORIGIN OF THE FATIGUE. ALS
