Event WPR19CA052
Aircraft involved
Probable cause & findings
An in-flight collision with a bird during low-altitude maneuvering, which resulted in a hard landing.
Factual narrative
The flight instructor reported that the student pilot was practicing takeoffs and landings at the airport. The student took off from spot C (taxiway Z), flying a right traffic pattern with the intent to land on taxiway A. As the helicopter was making a right crosswind turn over a golf course at an altitude of about 300 ft above ground level, a large bird flew out of the trees and struck the tail rotor. The flight instructor took over control as the helicopter began to yaw and he subsequently initiated an auto rotation to the golf course. As a result of a hard landing, the tailboom and fuselage were substantially damaged. The flight instructor reported no mechanical anomalies with the helicopter that would have precluded normal operation. Bird remains were found on the golf course and were identified as a Turkey Vulture. The average weight of the species is 4 pounds.
