CAUSES.

The Material Factor as the causal factor for this accident due to the detachment of a section of the blade (S/N A-5591) during flight which resulted in a dynamic imbalance, subsequent detachment of the mast and loss of control of the aircraft.
Contributing Factors
The Human Factor is a contributor to this accident due to:
The failure to timely detect damage to the blade top (white side) as a result of a previous impact, which left it exposed to the effect of the environment in a condition of stagnation conducive to localized corrosion attack (corrosion pitting), which ended in the final detachment of a part of the component.
The failure to comply with AD CF2011-44, which resulted in an unsafe condition in the operations of the equipment.
