Accident Overview
A helicopter operating under unknown registration and operator details crashed while on an aerial photography mission near a business agency. The purpose of the flight was to take aerial photographs of the business agency located near the crash site.
Observed Flight Path
Witnesses observed the helicopter circling a parking lot in a right-hand pattern at an altitude between 150 and 300 feet above ground level. After completing two to three orbits, the helicopter appeared to hover momentarily before pitching nose-down to a nearly inverted attitude. This was followed by a steep descent until impact with the ground.
Separation of Components
Following the pitch-over maneuver, pieces of the tail and/or main rotor blades separated from the helicopter. Post-crash examination revealed leading edge damage to the main rotor blades and paint transfer consistent with a strike against the tail boom prior to ground impact.
Wreckage Distribution
The main rotor and hub assembly were located approximately 30 feet from the main wreckage, indicating significant forces during the impact sequence.
Investigation
The accident investigation focused on the documented damage patterns but did not specify a probable cause or contributing factors in the source material.
