As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

FLIGHT WAS FOR A REGULATORY FLIGHT REVIEW FOR PIC (HIS FLIGHT REVIEW EXPIRED IN APRIL 2011). FLIGHT DEPARTED 1D2 AT APPROXIMATELY 1830 LOCAL AND PROCEEDED TO KOZW WHERE WITNESSES SAW THEM DOING AT LEAST 1 TOUCH AND GO LANDING.  WITNESS (PILOT WAITING TO TAKE-OFF)OBSERVED AIRCRAFT ON FINAL  APPROACH TO RUNWAY 31 AT KOZW, AND STATED THAT THE AIRCRAFT WAS "NOTICEABLY TOO HIGH AND AT A SLOW AIRSPEED" PERFORMING A SLIP WITH LEFT AILERON UP AND RIGHT RUDDER.
