The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
N-329PA, PA-28-181 aircraft with student pilot and instructor pilot on board departed Deer Valley Airport. After a normal climb out and as the aircraft transistions to cruise flight regime the student pilots aileron/elevator control came off in his hands. The instructor pilot in the right seat assumed control of the aircraft, declared an emergency and returned to Deer Valley Airport and made an uneventful landing. Subsequent investigation revealed the pin holding the universal joint together had sheared, the bushings fell out and the joint separated causing the control to fall out of the panel.
