Probable cause
The pilot's failure to maintain a proper glidepath to the runway.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot reported that the Navion A encountered little turbulence or crosswind when he entered the airport traffic pattern for landing, and that there were no problems with the handling and performance of the airplane. After completing before-landing checks, and with the airplane aligned on the final leg of the approach for landing, the pilot anticipated "lifting" and "sinking" effects as the airplane crossed two rows of trees prior to the landing threshold. After crossing the first row of trees, the pilot applied power, but the sink rate was greater than he anticipated, and the airplane struck the second row of trees, then impacted the ground.
