Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The acft collided with the ground after a in-flt main rotor blade separation during an aerial application flt. Inspection of the fracture surface of the failed blade revealed characteristics consistant with the high stress, low cycle fatigue. Lab findings will be compared with similiar failures which have occurred subsequent to the existing airworthiness directive (ai 80-14-12) requiring special inspection of the same failure area.
