Incident Overview
During entry into the airport traffic area while under positive control, an aircraft was struck on the underside of its stabilizer. The impact was caused by the propeller of another aircraft that was also entering the traffic pattern. The two aircraft were converging at the time of the collision.
Flight Continuation
After the strike, the affected aircraft proceeded to enter the traffic pattern, performed a touch-and-go landing, and subsequently executed a full-stop landing. The pilot of the aircraft did not become aware of the damage sustained during the incident.
Damage Discovery
The damage was discovered during the next preflight inspection by a different user of the aircraft. The inspection revealed two slash marks on the bottom of the horizontal stabilator and the trim tab. The slashes were consistent with contact from the propeller of the other aircraft. No other damage was reported.
