Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Approach
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

NTSB narrative

During a night instructional flight, the flight instructor simulated an engine failure while on the downwind leg of the traffic pattern. As the airplane approached the runway with the landing light off, the flight instructor noticed that they were low on the approach. When the instructor asked the student if the landing light was on, the student pilot promptly answered “no” and turned it on. The airplane struck trees at the same moment, which resulted in substantial damage to the wings and tail. A review of meteorological and astronomical data revealed there was a broken cloud layer at 6,000 feet above ground level and the phase of the moon was a waning crescent with 1% of the Moon’s visible disk illuminated. Further review indicated that the Moon had set about 1 hour and 43 minutes prior to the accident. The pilot reported no mechanical malfunctions or anomalies that would have precluded normal operation.

Probable cause

The pilot’s failure to maintain clearance from terrain on approach which resulted in controlled flight into trees. Contributing to the accident was the flight instructor’s inadequate supervision of the approach path, the dark night conditions and the landing light being off.

  • 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: local date, investigation status, cause areas. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2021-10-06.
