Narrative:
A Los Angeles Airways Sikorsky S-61L helicopter, N300Y, crashed at Compton, California. All 18 passengers and three crewmembers were fatally injured, and the aircraft was destroyed by impact and fire.
The flight was en route from Los Angeles International Airport to the heliport at Anaheim, California, when the yellow blade, one of five main rotor blades, separated at the spindle which attached the blade to the rotor head. Following the failure, the helicopter was uncontrollable and it fell to the ground .

The Safety Board determines that the probable cause of this accident was the fatigue failure of the yellow main rotor blade spindle, causing separation of the blade which made the aircraft uncontrollable. The fatigue crack originated in area of substandard hardness and inadequate shot peening.
