## Narrative

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

DURING A TELEPHONE INTERVIEW AIRMAN EXPLAINED THE ACCIDENT.  AIRMAN HAD FLOWN EARLIER IN THE DAY TO ELOY AZ. TO HAVE BREAKFAST WITH A FRIEND.  AFTER DEPARTING ELOY HE WENT TO AN UN-NAMED DESERT STRIP APPROXIMATELY TWO MILES EAST OF NEWMAN'S PEAK. THIS IS APPROXIMATELY 70 MILES SOUTH OF PHOENIX AND ADJACENT TO I-10 HIGHWAY. HE HAD ACCOMPLISHED ONE TOUCH AND GO AND WAS COMING AROUND FOR ANOTHER.  AIRMAN STATED HE TOUCHED DOWN NORMALLY TAILWHEEL FIRST, AS PER THE MANUFACTURER'S RECOMMENDATION.  HE APPLIED FORWARD CONTROL STICK PRESSURE TO RAISE THE TAIL WHILE SIMULTANEOUSLY APPLYING FULL THROTTLE.  AFTER HE HAD APPLIED FULL THROTTLE HE DROPPED HIS LEFT HAND OFF THE THROTTLE CONTROL TO REACH DOWN AND RESET THE ELEVATOR TRIM WHEEL FOR TAKE OFF.  AT ABOUT THIS POINT IN THE TOUCH AND GO THE NOSE OF THE AIRCRAFT ABRUPTLY TURNED TO THE RIGHT AND THE AIRCRAFT GROUND LOOPED, THE LEFT GEAR COLLAPESED AND THE LEFT WING CONTACTED THE GROUND.  AFTER THE AIRCRAFT CAME TO A STOP AIRMAN TURNED OFF ALL THE SWITCHES IN THE COCKPIT AND EXITED THE AIRCRAFT.  AIRMAN WENT ON TO STATE THAT AFTER HE HAD THOUGHT ABOUT IT AND REPLAYED THE WHOLE SEQUENCE IN HIS MIND HE REALIZED HE DID NOT APPLY ENOUGH FORWARD PRESSURE ON THE CONTROL STICK.  CONSEQUENTLY WHEN HE APPLIED POWER FOR TAKE-OFF THE TAIL WHEEL WAS STILL FULLY IN CONTACT WITH THE GROUND AND UNDER LOAD.  THE APPLICATION OF ENGINE POWER, THE APPLICATION OF RIGHT RUDDER TO COUNTER ACT THE P FACTOR AND THE FACT THAT THE TAIL WHEEL WAS STILL ON THE GROUND WAS THE IDEAL RECIPE FOR A GROUND LOOP.
