What happened
The helicopter was conducting a takeoff operation from a confined area with one passenger on board. During the initial climb phase, the pilot reported experiencing a sudden power loss at an altitude of approximately 40 feet above ground level (AGL). In response to this emergency, the pilot executed a 180-degree turn to establish a downwind landing pattern.
During the descent and subsequent touchdown, the aircraft struck a tree. The impact resulted in a hard landing that caused significant damage to the airframe and rotor systems. Specifically, the tail rotor, tail boom, and main rotor drive shaft were damaged during the incident.
The investigation
Following the accident, Federal Aviation Administration (FAA) personnel examined the helicopter's mechanical condition. They conducted an engine run-up test after the accident with no load applied to the system. The report indicated that the engine operated normally during this post-accident inspection, suggesting that a mechanical failure of the engine itself was not immediately evident during that specific check.
Findings
Weather conditions at the time of the takeoff were noted as variable winds with gusts. These environmental factors may have contributed to the difficulty in maintaining control or power management during the critical low-altitude phase of flight. The pilot's decision to turn downwind after a power loss at such a low altitude likely exacerbated the severity of the impact.
Safety message
Operations from confined areas require precise energy management and careful consideration of wind conditions. Pilots must be prepared for immediate power failures during takeoff and ensure that escape routes or safe landing zones are identified prior to initiating the climb.
