What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Witnesses saw the pilot attempting to take off from his driveway for a local flight. The helicopter lifted off into a hover, which witnesses described as "unstable," prompting the pilot to land. They then heard an increase in main rotor RPM, followed by a near-vertical climb. At about 80 feet above ground level, the helicopter suddenly descended, striking a tree with its tail rotor before hitting the ground with its main rotor blades. The helicopter came to rest on its left side, approximately 40 feet from its departure point. The aircart sustained substantial damage to the main rotor system, tail rotor system, landing gear, and the fuselage.
The pilot reported that he did not have sufficient power to maintain altitude and lost control of the helicopter.
