## Narrative

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

STUDENT PILOT WAS CONDUCTING HIS FIRST ?SOLO LAP? AFTER 35 HOURS OF INSTRUCTION IN A CESSNA C-172.  ACCORDING TO THE STUDENT PILOT, HE ACCELERATED THE AIRCRAFT UP TO AN AIR SPEED OF 55 KNOTS AND PULLED THE YOKE BACK SLOWLY TO ROTATE. IMMEDIATELY AFTER ROTATION, APPROXIMATELY TWO TO THREE FEET ABOVE RUNWAY 7R, THE PLANE BEGAN TO BANK TO THE RIGHT WHILE AT THE SAME TIME THE STUDENT PILOT WAS YAWING TO THE LEFT.  THE STUDENT PILOT PRESSED THE RIGHT RUDDER PEDAL AND TURNED THE YOKE TO THE LEFT IN AN ATTEMPT TO LEVEL THE WINGS OF THE AIRCRAFT. WHILE ATTEMPTING TO KEEP HIS HEADING, WHICH WAS TO HIS LEFT, THE AIRCRAFT WAS STILL WANTING TO BANK TO THE RIGHT. THE STUDENT FELT UNSAFE TO CONTINUE FLIGHT AND INSTANTLY REDUCED THE POWER TO IDLE. THIS CAUSED THE AIRCRAFT TO LOOSE AIRSPEED, DESCENDING DOWN INTO THE GRAVEL AREA LOCATED TO THE LEFT SIDE OF RUNWAY 7R.  WHEN THE AIRCRAFT CONTACTED THE GRAVEL FIELD, THE STUDENT PILOT APPLIED PRESSURE TO THE BRAKES TO REDUCE AIRSPEED IN ADDITION TO APPLYING PRESSURE TO THE RIGHT RUDDER PEDAL TO SITUATE THE AIRCRAFT BACK ONTO RUNWAY 7R.  WHILE MAKING THIS CORRECTION, THE RIGHT MAIN GEAR HIT A SIGNAGE AND JUMPED ON RUNWAY 7R.  ONCE THE PLANE WAS ON RUNWAY 7R, THE STUDENT PILOT ADDED LEFT RUDDER PRESSURE TO MAINTAIN THE AIRCRAFT ON CENTERLINE WHILE APPLYING MORE BREAK PRESSURE IN STOPPING THE AIRCRAFT.  HOWEVER, DUE TO THE RIGHT GEAR PREVIOUSLY HITTING OTHER SIGNAGE, THIS CAUSED BRAKING FAILURE TO THIS AIRCRAFT CAUSING IT TO SKID TO RIGHT OFF OF RUNWAY 7R INTO ANOTHER GRAVELLY FIELD. WHILE STILL TRAVELING, THE AIRCRAFT SKIDDED INTO SIGNAGE, C7 HITTING IT WITH THE NOSE OF THE AIRCRAFT CAUSING THE PLANE TO BE TURNED 180 DEGREES FROM IMPACT, COMING TO A STOP.
