Incident Details
An air ambulance helicopter experienced a tail rotor blade strike while maneuvering in dark night conditions within a confined landing zone. The tail rotor blades struck a tree during the maneuver. After the impact, the pilot did not detect any vibration in the anti-torque pedals or airframe and proceeded to land safely.
Post-Event Actions
Following the landing, the pilot chose not to shut down the aircraft. He conducted an inspection of the tail rotor and then returned to the hospital. At the hospital, the pilot performed another inspection of the tail rotor, this time with the assistance of the company mechanic on duty. Based on their assessment, they determined that the aircraft was airworthy.
Outcome
The following day, during a preflight inspection, another pilot discovered the damage on the tail rotor blades. The damaged tail rotor blades were subsequently removed and replaced.
