NTSB narrative
AT APPROX 200 FEET AGL, UPON COMPLETION OF A PRACTICE FORCED LANDING PROCEDURE, CARBURETOR HEAT WAS DE-SELECTED, FULL THROTTLE APPLIED AND THE FLAP SETTING REDUCED FROM 40 DEG TO 20 DEG. ACCORDING TO THE CFI, THE ENGINE DID NOT DEVELOP FULL POWER WITH THE RPM OBSERVED TO BE 2100 VICE 2700 RPM AT RATED POWER. THE AIRPLANE CONTINUED ON THE SAME HEADING, CROSSED OVER A WOODED AREA BARELY CLEARING THE TREES, AND SETTLED IN A NOSE-HIGH, CONTROLLED ATTITUDE, INTO THE TREES FOLLOWED BY GROUND CONTACT. EXAMINATION AT THE CRASH SITE REVEALED THAT THE CARBURETOR HEAT VALVE OPERATED NORMALLY, THE ENGINE SPARK PLUGS AND EXHAUST STACKS WERE FREE FROM MAJOR DEPOSITS AND THAT THE OUTBOARD TIPS OF THE PROPELLER BLADES WERE BENT OPPOSITE TO THE DIRECTION OF ROTATION. A FOUR INCH DIAMETER OAK LIMB HAD BEEN SLASHED BY THE PROPELLER.
Probable cause
THE FAILURE OF THE ENGINE TO DEVELOP FULL RATED POWER FOR UNKNOWN REASONS.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
