- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Controlled flight into terrain/object (CFIT)
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary

NTSB narrative
The student pilot was conducting a solo flight and stated that, while on approach for landing, she had just reduced engine power when the tower controller asked her to extend the downwind leg of the airport traffic pattern due to other traffic. She subsequently became distracted looking for the other traffic and did not increase engine power to maintain altitude. The controller then instructed her to turn onto the base leg and she complied; however, the airplane continued to descend and collided with trees before coming to rest upright on the ground. Examination of the wreckage did not reveal any preimpact mechanical malfunctions, nor did the student pilot report any.
Probable cause
The student pilot’s failure to maintain altitude during approach, which resulted in controlled flight into terrain. Contributing to the accident was the student’s distraction due to other traffic in the airport traffic pattern.

- 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, coordinates. 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.
