Analysis

The pilot of the landing aircraft failed to see and avoid the departing aircraft. The aircraft struck the departing aircrafts vertical stabilizer and rudder with the propeller. Approximately 40% of the vertical stabilizer and rudder separated from the aircraft during the propeller strike.

Before the pilot used the runway at an uncontrolled airport she failed to look for and observe the landing traffic. The aircraft was not equipped with a communications radio. This was the pilot's first takeoff of the day and had planned on making several touch and goes. During takeoff the pilot heard a 'crunch' but was unaware of the landing aircraft's propeller strike which sliced off 40% of the vertical stabilixer and rudder. A normal traffic pattern was flown with a successful landing.
