Accident occurred Thursday, August 04, 2016 in Homer, AK
Probable Cause Approval Date: 12/05/2016
Aircraft: ROBINSON HELICOPTER COMPANY R44 II, registration: N719TF
Injuries: 3 Uninjured.
NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
The pilot stated that while en route, about 1,000 feet above ground level (agl), a loud sound was heard in conjunction with feeling a "bump." At this point, a vibration was felt in the control pedals and a precautionary landing was executed. Upon inspection, an estimated 3-inch area of the tail rotor blade exhibited signs consistent with buckling.
Witnesses on the ground reported seeing an object consistent with a bird fall from the sky after contact with the helicopter. No panels or other equipment was missing from the helicopter during an inspection following the landing. The pilot reported no pre-impact mechanical malfunctions or anomalies that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
An in-flight collision with a bird resulting in damage to a tail rotor blade, which required replacement.
