## Narrative

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

THE FLIGHT WAS SCHEDULED TO REVIEW FLIGHT MANEUVERS PRIOR TO THE STUDEN'S PRACTICAL FLIGHT TEST FOR THE PRIVATE PILOT CERTIFICATE. THE AIRPLANE WAS CONFIGURED WITH 25 DEGREES OF FLAPS FOR A SIMULATED SHORT FIELD TAKEOFF. THE FLIGHT INSTRUCTOR ADDED THAT 'THE ENGINE SOUNDED SMOOTH DURING THE ENTIRE FLIGHT' AND THE AIRPLANE APPEARED TO ACCELERATE NORMALLY AS IT BECAME AIRBORNE BY 2,000 FOOT RUNWAY MARKER. AFTER BREAKING GROUND, THE 66 HOUR STUDENT PILOT EXTIBLISHED THE AIRPLANE AT THE BEST ANGLE OF CLIMB SPEED; HOWEVER, THE AIRPLANE'S CLIMB PERFORMANCE WAS DEGRADED TO THE POINT THAT THE AIRPLANE WAS ONLY CLIMBING AT A RATE OF 100 FPM.THE FLIGHT INSTRUCTOR ASSUMED THE CONTROLS AND INITIALLY MANAGED TO MANEUVER THE AIRPLANE AROUND RISING TERRAIN AND OBSGTRUCTIONS AT THE DEPARTURE END OF THE RUNWAY. THE ENGINE WAS EXAMINED UNDER THE SUPERVISION OF THE FAA INSPECTOR. THE ENGINE WAS STARTED ANDOPERATED THROUGH THE NORMAL FLIGHT PARAMETERS. NO PRE-EXISTING ENGINE DEFICIENCIES WERE NOTED AND THE INVESTIGATION DID NOT REVEAL ANY EVIDENCE THAT THE ENGINE WAS NOT CAPABLE OF OPERATING AND PRODUCING POWER PRIOR TO THE ACCIDENT.                                                                     (-23) FOLLOWING TAKEOFF OUT OF TULSA DOWNTOWN AIRPARK, THE AIRCRAFT WAS UNABLE TO CLIMB ABOVE TERRAIN DUE TO LOW PERFORMANCE FROM ENGINE. THE INSTRUCTOR TOOK OVER THE CONTROLS AND MADE A FORCED LANDING IN A FIELD ONE MILE SOUTH OF THE AIRPARK.
