Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
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
Takeoff
First occurrenceThe 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
In flight collision with object
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

DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

THE PILOT AND A PASSENGER WERE DEPARTING A HUNTING LODGE AIRSTRIP, WHICH WAS LOCATED ON A KNOLL, ABOUT 300 FEET ABOVE THE SURROUNDING TERRAIN. THE AIRSTRIP WAS ABOUT 900 FEET LONG AND SLOPED DOWNHILL ABOUT 2 DEGREES. THE PILOT INDICATED THAT THE WIND WAS BLOWING GENERALLY FROM THE WEST ABOUT 12 KNOTS WITH GUSTS TO 15 KNOTS, BUT VARIED FROM THE NORTHWEST TO THE SOUTHEAST. THE AIRPLANE WAS 31 POUNDS BELOW ITS MAXIMUM GROSS WEIGHT. THE PILOT STARTED HIS TAKEOFF ROLL TO THE SOUTH. AT ABOUT 50 MPH OF AIRSPEED, HE ATTEMPTED TO 'ROTATE' THE AIRPLANE FOR TAKEOFF. HE SAID THAT THE AIRPLANE DID NOT ROTATE, BUT TOOK OFF AS IT CONTINUED OFF THE DEPARTURE END OF THE AIRSTRIP. THE PILOT ATTEMPTED TO GAIN AIRSPEED BY LOWERING THE NOSE OF THE AIRPLANE AS IT DESCENDED TOWARD LOWER TERRAIN. THE AIRPLANE STRUCK SEVERAL TREES ABOUT 200 YARDS FROM THE END OF THE AIRSTRIP. THE PILOT REPORTED THAT THE AIRPLANE ENCOUNTERED AN UNEXPECTED TAILWIND OR DOWNDRAFT.

Probable cause

THE PILOT'S IMPROPER PLANNING/DECISION AND FAILURE TO ATTAIN SUFFICIENT AIRSPEED TO SUSTAIN A CLIMB BEFORE HITTING TREES. THE UNFAVORABLE WIND CONDITION WAS A RELATED FACTOR.

  • 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. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1995-08-15.
  • API snapshot SHA-256: 1ed198c10eaa3d9fec3b89b222c84b443ad195b0f400fca18f7d58286992c9ac; retrieved 2026-09-21T13:08:45.278Z.
