Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The air ambulance pilot reported that he was enroute to his destination when two large birds impacted the helicopter, which resulted in substantial damage to the pitch change link assembly and drive link assembly. The helicopter began to “hop vertically” and controllability was in question, so the pilot made a precautionary landing without incident.
