What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
In the morning of February 18, 2018, a student pilot and his flight instructor departed Valkaria Airport to the practice area in a Cessna 152. Between 0900 and 1000. They returned to the airport in order for the student to practice a few more touch and go landings. At 1000 feet while flying in the traffic pattern, suddenly, they heard a strange noise, and the student felt that the aircraft needed more trimming than before. The flight instructor took over the flight controls but could not detect anything unusual. During the post flight inspection they found a bullet hole on the left side of the rudder and a protusion on the right side of the rudder. It appeared that the bullet was still inside the rudder.
