## Narrative

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

KATANA ACFT REPORTED ENGINE PROBLEMS SHORTLY AFTER TAKEOFF AND CRASHED INTO A FIELD. (.4) THE STUDENT PILOT REPORTED THAT WHILE LANDING AT THE AIRPORT SHE MADE A VERY STEEP APPROACH THAT RESULTED IN WHAT SHE DESCRIBED AS A HARD LANDING WITH SEVERAL BOUNCES ON THE RUNWAY. THE RUNWAY SURFACE WAS MADE OUT OF ASPHALT.  SHE FOUND NO DAMAGE DURING A POSTFLIGHT INSPECTION AND DECIDED TO CONTINUE THE FLIGHT BACK TO SANTA ROSA.  SHE SAID THE RUN-UP WAS NORMAL AND THEN DEPARTED.  AFTER CLIMBING 200 HUNDRED FEET, THE PILOT FELT THAT SOMETHING WAS WRONG WITH THE WAY THE AIRPLANE WAS PERFORMING SINCE IT WAS NOT GAINING MUCH ALTITUDE. FOLLOWING A CHECK OF THE POWER INSTRUMENTS AND CONTROL POSITIONS, THE PILOT CONTINUED IN THE CLIMB.  THE AIRPLANE CLIMBED VERY SLOWLY AND REACHED 1,000 FEET AGL, ABOUT 10 MILES FROM THE AIRPORT.  AT THAT TIME, THE PILOT REALIZED SHE SHOULD HAVE BEEN MUCH HIGHER AND BOTH THE ENGINE AND AIRPLANE SEEMED LIKE IT DID NOT HAVE ENOUGH POWER.  THE STUDENT THEN TURNED BACK TOWARD THE AIRPORT AS THE AIRPLANE BEGAN DESCENDING.  ABOUT 4 MILES FROM THE RUNWAY THE AIRCRAFT WAS AT 700 FEET AGL AND STILL DESCENDING.  THE PILOT THEN SELECTED A FIELD AND SET UP FOR A FORCED LANDING . SHE STATED THAT THE AIRPLANE TOUCHED DOWN AND THEN SPUN AROUND 180 DEGREES.  AN FAA INSPECTOR EXAMINED THE AIRPLANE AND ENGINE.  ACCORDING TO THE INSPECTOR'S STATEMENT, NO PREIMPACT DISCREPANCIES WERE NOTED WITH THE AIRFRAME, ENGINE, OR FUEL SYSTEM.  THE PROPELLER WAS DEFORMED AND EXHIBITED BOTH TIP END DAMAGE AND CHORDWISE SCRATCHES.  THE PROPELLER DAMAGE WAS NOT CONSISTENT WITH THE NATURE OF THE FIELD IN WHICH THE PILOT LANDED, BUT WAS CONSISTENT ASPHALT CONTACT.                                                     (-23) IT WAS FOUND THAT THE STUDENT PILOT, MRS. KAREN WILLIAM HAD MADE A HARD LANDING AT THE WATTS WOODLAND AIRPORT RIGHT BEFORE DEPARTING AND LOSING PERFORMANCE AS EXPLAINED IN THE PREVIOUS 8020-23 DATED 08/21/98. DURING THE HARD LANDING, THE PROPELLER STRUCK THE RUNWAY WHICH EXPLAINS THE LACK OF PERFORMANCE DURING THE CLIMB OUT. THE STUDENT ADMITS THE HARD LANDING BUT INDICATES THAT AT THAT TIME SHE DID NOT KNOW THAT THE PROPELLER HAD HIT THE GROUND.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB LAX98LA272](https://openairdocs.org/ntsb/LAX98LA272), Aug 18, 1998: Diamond Aircraft Industries DA-20-A1 (N606F), Woodland, CA, substantial damage. Probable cause: The pilot's failure during a preflight inspection to detect the damaged propeller from the previous hard landing. The damaged propeller degraded the climb performance capability of the airplane.
